Do this:
|
|
#define SOKOL_IMPL or
|
|
#define SOKOL_APP_IMPL
|
|
before you include this file in *one* C or C++ file to create the
|
|
implementation.
|
|
|
|
In the same place define one of the following to select the 3D-API
|
|
which should be initialized by sokol_app.h (this must also match
|
|
the backend selected for sokol_gfx.h if both are used in the same
|
|
project):
|
|
|
|
#define SOKOL_GLCORE33
|
|
#define SOKOL_GLES3
|
|
#define SOKOL_D3D11
|
|
#define SOKOL_METAL
|
|
#define SOKOL_WGPU
|
|
|
|
Optionally provide the following defines with your own implementations:
|
|
|
|
SOKOL_ASSERT(c) - your own assert macro (default: assert(c))
|
|
SOKOL_UNREACHABLE() - a guard macro for unreachable code (default: assert(false))
|
|
SOKOL_WIN32_FORCE_MAIN - define this on Win32 to use a main() entry point instead of WinMain
|
|
SOKOL_NO_ENTRY - define this if sokol_app.h shouldn't "hijack" the main() function
|
|
SOKOL_APP_API_DECL - public function declaration prefix (default: extern)
|
|
SOKOL_API_DECL - same as SOKOL_APP_API_DECL
|
|
SOKOL_API_IMPL - public function implementation prefix (default: -)
|
|
|
|
Optionally define the following to force debug checks and validations
|
|
even in release mode:
|
|
|
|
SOKOL_DEBUG - by default this is defined if _DEBUG is defined
|
|
|
|
If sokol_app.h is compiled as a DLL, define the following before
|
|
including the declaration or implementation:
|
|
|
|
SOKOL_DLL
|
|
|
|
On Windows, SOKOL_DLL will define SOKOL_APP_API_DECL as __declspec(dllexport)
|
|
or __declspec(dllimport) as needed.
|
|
|
|
On Linux, SOKOL_GLCORE33 can use either GLX or EGL.
|
|
GLX is default, set SOKOL_FORCE_EGL to override.
|
|
|
|
For example code, see https://github.com/floooh/sokol-samples/tree/master/sapp

Portions of the Windows and Linux GL initialization, event-, icon- etc... code
|
|
have been taken from GLFW (http://www.glfw.org/)
|

|
|
Link with the following system libraries:
|
|
|
|
- on macOS with Metal: Cocoa, QuartzCore, Metal, MetalKit
|
|
- on macOS with GL: Cocoa, QuartzCore, OpenGL
|
|
- on iOS with Metal: Foundation, UIKit, Metal, MetalKit
|
|
- on iOS with GL: Foundation, UIKit, OpenGLES, GLKit

- on Linux with EGL: X11, Xi, Xcursor, EGL, GL (or GLESv2), dl, pthread, m(?)
|
|
- on Linux with GLX: X11, Xi, Xcursor, GL, dl, pthread, m(?)
|
|
- on Android: GLESv3, EGL, log, android
|
|
- on Windows with the MSVC or Clang toolchains: no action needed, libs are defined in-source via pragma-comment-lib
|
|
- on Windows with MINGW/MSYS2 gcc: compile with '-mwin32' so that _WIN32 is defined
|
|
- link with the following libs: -lkernel32 -luser32 -lshell32
|
|
- additionally with the GL backend: -lgdi32
|
|
- additionally with the D3D11 backend: -ld3d11 -ldxgi
|
|
|
|
On Linux, you also need to use the -pthread compiler and linker option, otherwise weird
|
|
things will happen, see here for details: https://github.com/floooh/sokol/issues/376
|
|
|
|
On macOS and iOS, the implementation must be compiled as Objective-C.

FEATURE OVERVIEW
|
|
================
|
|
sokol_app.h provides a minimalistic cross-platform API which
|
|
implements the 'application-wrapper' parts of a 3D application:
|
|
|
|
- a common application entry function
|
|
- creates a window and 3D-API context/device with a 'default framebuffer'
|
|
- makes the rendered frame visible
|
|
- provides keyboard-, mouse- and low-level touch-events
|
|
- platforms: MacOS, iOS, HTML5, Win32, Linux/RaspberryPi, Android
|
|
- 3D-APIs: Metal, D3D11, GL3.2, GLES3, WebGL, WebGL2

STEP BY STEP
|
|
============
|
|
--- Add a sokol_main() function to your code which returns a sapp_desc structure
|
|
with initialization parameters and callback function pointers. This
|
|
function is called very early, usually at the start of the
|
|
platform's entry function (e.g. main or WinMain). You should do as
|
|
little as possible here, since the rest of your code might be called
|
|
from another thread (this depends on the platform):
|
|
|
|
sapp_desc sokol_main(int argc, char* argv[]) {
|
|
return (sapp_desc) {
|
|
.width = 640,
|
|
.height = 480,
|
|
.init_cb = my_init_func,
|
|
.frame_cb = my_frame_func,
|
|
.cleanup_cb = my_cleanup_func,
|
|
.event_cb = my_event_func,
|
|
...
|
|
};
|
|
}
|
|
|
|
To get any logging output in case of errors you need to provide a log
|
|
callback. The easiest way is via sokol_log.h:
|
|
|
|
#include "sokol_log.h"
|
|
|
|
sapp_desc sokol_main(int argc, char* argv[]) {
|
|
return (sapp_desc) {
|
|
...
|
|
.logger.func = slog_func,
|
|
};
|
|
}
|
|
|
|
There are many more setup parameters, but these are the most important.
|
|
For a complete list search for the sapp_desc structure declaration
|
|
below.
|
|
|
|
DO NOT call any sokol-app function from inside sokol_main(), since
|
|
sokol-app will not be initialized at this point.
|
|
|
|
The .width and .height parameters are the preferred size of the 3D
|
|
rendering canvas. The actual size may differ from this depending on
|
|
platform and other circumstances. Also the canvas size may change at
|
|
any time (for instance when the user resizes the application window,
|
|
or rotates the mobile device). You can just keep .width and .height
|
|
zero-initialized to open a default-sized window (what "default-size"
|
|
exactly means is platform-specific, but usually it's a size that covers
|
|
most of, but not all, of the display).
|
|
|
|
All provided function callbacks will be called from the same thread,
|
|
but this may be different from the thread where sokol_main() was called.
|
|
|
|
.init_cb (void (*)(void))
|
|
This function is called once after the application window,
|
|
3D rendering context and swap chain have been created. The
|
|
function takes no arguments and has no return value.
|
|
.frame_cb (void (*)(void))
|
|
This is the per-frame callback, which is usually called 60
|
|
times per second. This is where your application would update
|
|
most of its state and perform all rendering.
|
|
.cleanup_cb (void (*)(void))
|
|
The cleanup callback is called once right before the application
|
|
quits.
|
|
.event_cb (void (*)(const sapp_event* event))
|
|
The event callback is mainly for input handling, but is also
|
|
used to communicate other types of events to the application. Keep the
|
|
event_cb struct member zero-initialized if your application doesn't require
|
|
event handling.
|
|
|
|
As you can see, those 'standard callbacks' don't have a user_data
|
|
argument, so any data that needs to be preserved between callbacks
|
|
must live in global variables. If keeping state in global variables
|
|
is not an option, there's an alternative set of callbacks with
|
|
an additional user_data pointer argument:
|
|
|
|
.user_data (void*)
|
|
The user-data argument for the callbacks below
|
|
.init_userdata_cb (void (*)(void* user_data))
|
|
.frame_userdata_cb (void (*)(void* user_data))
|
|
.cleanup_userdata_cb (void (*)(void* user_data))
|
|
.event_userdata_cb (void(*)(const sapp_event* event, void* user_data))
|
|
|
|
The function sapp_userdata() can be used to query the user_data
|
|
pointer provided in the sapp_desc struct.
|
|
|
|
You can also call sapp_query_desc() to get a copy of the
|
|
original sapp_desc structure.
|
|
|
|
NOTE that there's also an alternative compile mode where sokol_app.h
|
|
doesn't "hijack" the main() function. Search below for SOKOL_NO_ENTRY.
|
|
|
|
--- Implement the initialization callback function (init_cb), this is called
|
|
once after the rendering surface, 3D API and swap chain have been
|
|
initialized by sokol_app. All sokol-app functions can be called
|
|
from inside the initialization callback, the most useful functions
|
|
at this point are:
|
|
|
|
int sapp_width(void)
|
|
int sapp_height(void)
|
|
Returns the current width and height of the default framebuffer in pixels,
|
|
this may change from one frame to the next, and it may be different
|
|
from the initial size provided in the sapp_desc struct.
|
|
|
|
float sapp_widthf(void)
|
|
float sapp_heightf(void)
|
|
These are alternatives to sapp_width() and sapp_height() which return
|
|
the default framebuffer size as float values instead of integer. This
|
|
may help to prevent casting back and forth between int and float
|
|
in more strongly typed languages than C and C++.
|
|
|
|
double sapp_frame_duration(void)
|
|
Returns the frame duration in seconds averaged over a number of
|
|
frames to smooth out any jittering spikes.
|
|
|
|
int sapp_color_format(void)
|
|
int sapp_depth_format(void)
|
|
The color and depth-stencil pixelformats of the default framebuffer,
|
|
as integer values which are compatible with sokol-gfx's
|
|
sg_pixel_format enum (so that they can be plugged directly in places
|
|
where sg_pixel_format is expected). Possible values are:
|
|
|
|
23 == SG_PIXELFORMAT_RGBA8
|
|
28 == SG_PIXELFORMAT_BGRA8
|
|
42 == SG_PIXELFORMAT_DEPTH
|
|
43 == SG_PIXELFORMAT_DEPTH_STENCIL
|
|
|
|
int sapp_sample_count(void)
|
|
Return the MSAA sample count of the default framebuffer.
|
|
|
|
const void* sapp_metal_get_device(void)
|
|
const void* sapp_metal_get_renderpass_descriptor(void)
|
|
const void* sapp_metal_get_drawable(void)
|
|
If the Metal backend has been selected, these functions return pointers
|
|
to various Metal API objects required for rendering, otherwise
|
|
they return a null pointer. These void pointers are actually
|
|
Objective-C ids converted with a (ARC) __bridge cast so that
|
|
the ids can be tunnel through C code. Also note that the returned
|
|
pointers to the renderpass-descriptor and drawable may change from one
|
|
frame to the next, only the Metal device object is guaranteed to
|
|
stay the same.
|
|
|
|
const void* sapp_macos_get_window(void)
|
|
On macOS, get the NSWindow object pointer, otherwise a null pointer.
|
|
Before being used as Objective-C object, the void* must be converted
|
|
back with a (ARC) __bridge cast.
|
|
|
|
const void* sapp_ios_get_window(void)
|
|
On iOS, get the UIWindow object pointer, otherwise a null pointer.
|
|
Before being used as Objective-C object, the void* must be converted
|
|
back with a (ARC) __bridge cast.
|
|
|
|
const void* sapp_win32_get_hwnd(void)
|
|
On Windows, get the window's HWND, otherwise a null pointer. The
|
|
HWND has been cast to a void pointer in order to be tunneled
|
|
through code which doesn't include Windows.h.
|
|
|
|
const void* sapp_d3d11_get_device(void)
|
|
const void* sapp_d3d11_get_device_context(void)
|
|
const void* sapp_d3d11_get_render_target_view(void)
|
|
const void* sapp_d3d11_get_depth_stencil_view(void)
|
|
Similar to the sapp_metal_* functions, the sapp_d3d11_* functions
|
|
return pointers to D3D11 API objects required for rendering,
|
|
only if the D3D11 backend has been selected. Otherwise they
|
|
return a null pointer. Note that the returned pointers to the
|
|
render-target-view and depth-stencil-view may change from one
|
|
frame to the next!
|
|
|
|
const void* sapp_wgpu_get_device(void)
|
|
const void* sapp_wgpu_get_render_view(void)
|
|
const void* sapp_wgpu_get_resolve_view(void)
|
|
const void* sapp_wgpu_get_depth_stencil_view(void)
|
|
These are the WebGPU-specific functions to get the WebGPU
|
|
objects and values required for rendering. If sokol_app.h
|
|
is not compiled with SOKOL_WGPU, these functions return null.
|
|
|
|
const void* sapp_android_get_native_activity(void);
|
|
On Android, get the native activity ANativeActivity pointer, otherwise
|
|
a null pointer.
|
|
|
|
--- Implement the frame-callback function, this function will be called
|
|
on the same thread as the init callback, but might be on a different
|
|
thread than the sokol_main() function. Note that the size of
|
|
the rendering framebuffer might have changed since the frame callback
|
|
was called last. Call the functions sapp_width() and sapp_height()
|
|
each frame to get the current size.
|
|
|
|
--- Optionally implement the event-callback to handle input events.
|
|
sokol-app provides the following type of input events:
|
|
- a 'virtual key' was pressed down or released
|
|
- a single text character was entered (provided as UTF-32 code point)
|
|
- a mouse button was pressed down or released (left, right, middle)
|
|
- mouse-wheel or 2D scrolling events
|
|
- the mouse was moved
|
|
- the mouse has entered or left the application window boundaries
|
|
- low-level, portable multi-touch events (began, moved, ended, cancelled)
|
|
- the application window was resized, iconified or restored
|
|
- the application was suspended or restored (on mobile platforms)
|
|
- the user or application code has asked to quit the application
|
|
- a string was pasted to the system clipboard
|
|
- one or more files have been dropped onto the application window
|
|
|
|
To explicitly 'consume' an event and prevent that the event is
|
|
forwarded for further handling to the operating system, call
|
|
sapp_consume_event() from inside the event handler (NOTE that
|
|
this behaviour is currently only implemented for some HTML5
|
|
events, support for other platforms and event types will
|
|
be added as needed, please open a github ticket and/or provide
|
|
a PR if needed).
|
|
|
|
NOTE: Do *not* call any 3D API rendering functions in the event
|
|
callback function, since the 3D API context may not be active when the
|
|
event callback is called (it may work on some platforms and 3D APIs,
|
|
but not others, and the exact behaviour may change between
|
|
sokol-app versions).
|
|
|
|
--- Implement the cleanup-callback function, this is called once
|
|
after the user quits the application (see the section
|
|
"APPLICATION QUIT" for detailed information on quitting
|
|
behaviour, and how to intercept a pending quit - for instance to show a
|
|
"Really Quit?" dialog box). Note that the cleanup-callback isn't
|
|
guaranteed to be called on the web and mobile platforms.
|
|
|
|
MOUSE CURSOR TYPE AND VISIBILITY
|
|
================================
|
|
You can show and hide the mouse cursor with
|
|
|
|
void sapp_show_mouse(bool show)
|
|
|
|
And to get the current shown status:
|
|
|
|
bool sapp_mouse_shown(void)
|
|
|
|
NOTE that hiding the mouse cursor is different and independent from
|
|
the MOUSE/POINTER LOCK feature which will also hide the mouse pointer when
|
|
active (MOUSE LOCK is described below).
|
|
|
|
To change the mouse cursor to one of several predefined types, call
|
|
the function:
|
|
|
|
void sapp_set_mouse_cursor(sapp_mouse_cursor cursor)
|
|
|
|
Setting the default mouse cursor SAPP_MOUSECURSOR_DEFAULT will restore
|
|
the standard look.
|
|
|
|
To get the currently active mouse cursor type, call:
|
|
|
|
sapp_mouse_cursor sapp_get_mouse_cursor(void)
|
|
|
|
MOUSE LOCK (AKA POINTER LOCK, AKA MOUSE CAPTURE)
|
|
================================================
|
|
In normal mouse mode, no mouse movement events are reported when the
|
|
mouse leaves the windows client area or hits the screen border (whether
|
|
it's one or the other depends on the platform), and the mouse move events
|
|
(SAPP_EVENTTYPE_MOUSE_MOVE) contain absolute mouse positions in
|
|
framebuffer pixels in the sapp_event items mouse_x and mouse_y, and
|
|
relative movement in framebuffer pixels in the sapp_event items mouse_dx
|
|
and mouse_dy.
|
|
|
|
To get continuous mouse movement (also when the mouse leaves the window
|
|
client area or hits the screen border), activate mouse-lock mode
|
|
by calling:
|
|
|
|
sapp_lock_mouse(true)
|
|
|
|
When mouse lock is activated, the mouse pointer is hidden, the
|
|
reported absolute mouse position (sapp_event.mouse_x/y) appears
|
|
frozen, and the relative mouse movement in sapp_event.mouse_dx/dy
|
|
no longer has a direct relation to framebuffer pixels but instead
|
|
uses "raw mouse input" (what "raw mouse input" exactly means also
|
|
differs by platform).
|
|
|
|
To deactivate mouse lock and return to normal mouse mode, call
|
|
|
|
sapp_lock_mouse(false)
|
|
|
|
And finally, to check if mouse lock is currently active, call
|
|
|
|
if (sapp_mouse_locked()) { ... }
|
|
|
|
On native platforms, the sapp_lock_mouse() and sapp_mouse_locked()
|
|
functions work as expected (mouse lock is activated or deactivated
|
|
immediately when sapp_lock_mouse() is called, and sapp_mouse_locked()
|
|
also immediately returns the new state after sapp_lock_mouse()
|
|
is called.
|
|
|
|
On the web platform, sapp_lock_mouse() and sapp_mouse_locked() behave
|
|
differently, as dictated by the limitations of the HTML5 Pointer Lock API:
|
|
|
|
- sapp_lock_mouse(true) can be called at any time, but it will
|
|
only take effect in a 'short-lived input event handler of a specific
|
|
type', meaning when one of the following events happens:
|
|
- SAPP_EVENTTYPE_MOUSE_DOWN
|
|
- SAPP_EVENTTYPE_MOUSE_UP
|
|
- SAPP_EVENTTYPE_MOUSE_SCROLL
|
|
- SAPP_EVENTTYPE_KEY_UP
|
|
- SAPP_EVENTTYPE_KEY_DOWN
|
|
- The mouse lock/unlock action on the web platform is asynchronous,
|
|
this means that sapp_mouse_locked() won't immediately return
|
|
the new status after calling sapp_lock_mouse(), instead the
|
|
reported status will only change when the pointer lock has actually
|
|
been activated or deactivated in the browser.
|
|
- On the web, mouse lock can be deactivated by the user at any time
|
|
by pressing the Esc key. When this happens, sokol_app.h behaves
|
|
the same as if sapp_lock_mouse(false) is called.
|
|
|
|
For things like camera manipulation it's most straightforward to lock
|
|
and unlock the mouse right from the sokol_app.h event handler, for
|
|
instance the following code enters and leaves mouse lock when the
|
|
left mouse button is pressed and released, and then uses the relative
|
|
movement information to manipulate a camera (taken from the

CLIPBOARD SUPPORT
|
|
=================
|
|
Applications can send and receive UTF-8 encoded text data from and to the
|
|
system clipboard. By default, clipboard support is disabled and
|
|
must be enabled at startup via the following sapp_desc struct
|
|
members:
|
|
|
|
sapp_desc.enable_clipboard - set to true to enable clipboard support
|
|
sapp_desc.clipboard_size - size of the internal clipboard buffer in bytes
|
|
|
|
Enabling the clipboard will dynamically allocate a clipboard buffer
|
|
for UTF-8 encoded text data of the requested size in bytes, the default
|
|
size is 8 KBytes. Strings that don't fit into the clipboard buffer
|
|
(including the terminating zero) will be silently clipped, so it's
|
|
important that you provide a big enough clipboard size for your
|
|
use case.
|
|
|
|
To send data to the clipboard, call sapp_set_clipboard_string() with
|
|
a pointer to an UTF-8 encoded, null-terminated C-string.
|
|
|
|
NOTE that on the HTML5 platform, sapp_set_clipboard_string() must be
|
|
called from inside a 'short-lived event handler', and there are a few
|
|
other HTML5-specific caveats to workaround. You'll basically have to
|
|
tinker until it works in all browsers :/ (maybe the situation will
|
|
improve when all browsers agree on and implement the new
|
|
HTML5 navigator.clipboard API).
|
|
|
|
To get data from the clipboard, check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED
|
|
event in your event handler function, and then call sapp_get_clipboard_string()
|
|
to obtain the pasted UTF-8 encoded text.
|
|
|
|
NOTE that behaviour of sapp_get_clipboard_string() is slightly different
|
|
depending on platform:
|
|
|
|
- on the HTML5 platform, the internal clipboard buffer will only be updated
|
|
right before the SAPP_EVENTTYPE_CLIPBOARD_PASTED event is sent,
|
|
and sapp_get_clipboard_string() will simply return the current content
|
|
of the clipboard buffer
|
|
- on 'native' platforms, the call to sapp_get_clipboard_string() will
|
|
update the internal clipboard buffer with the most recent data
|
|
from the system clipboard
|
|
|
|
Portable code should check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED event,
|
|
and then call sapp_get_clipboard_string() right in the event handler.
|
|
|
|
The SAPP_EVENTTYPE_CLIPBOARD_PASTED event will be generated by sokol-app
|
|
as follows:
|
|
|
|
- on macOS: when the Cmd+V key is pressed down
|
|
- on HTML5: when the browser sends a 'paste' event to the global 'window' object
|
|
- on all other platforms: when the Ctrl+V key is pressed down
|
|
|
|
DRAG AND DROP SUPPORT
|
|
=====================
|
|
PLEASE NOTE: the drag'n'drop feature works differently on WASM/HTML5
|
|
and on the native desktop platforms (Win32, Linux and macOS) because
|
|
of security-related restrictions in the HTML5 drag'n'drop API. The
|
|
WASM/HTML5 specifics are described at the end of this documentation
|
|
section:
|
|
|
|
Like clipboard support, drag'n'drop support must be explicitly enabled
|
|
at startup in the sapp_desc struct.
|
|
|
|
sapp_desc sokol_main() {
|
|
return (sapp_desc) {
|
|
.enable_dragndrop = true, // default is false
|
|
...
|
|
};
|
|
}
|
|
|
|
You can also adjust the maximum number of files that are accepted
|
|
in a drop operation, and the maximum path length in bytes if needed:
|
|
|
|
sapp_desc sokol_main() {
|
|
return (sapp_desc) {
|
|
.enable_dragndrop = true, // default is false
|
|
.max_dropped_files = 8, // default is 1
|
|
.max_dropped_file_path_length = 8192, // in bytes, default is 2048
|
|
...
|
|
};
|
|
}
|
|
|
|
When drag'n'drop is enabled, the event callback will be invoked with an
|
|
event of type SAPP_EVENTTYPE_FILES_DROPPED whenever the user drops files on
|
|
the application window.
|
|
|
|
After the SAPP_EVENTTYPE_FILES_DROPPED is received, you can query the
|
|
number of dropped files, and their absolute paths by calling separate
|
|
functions:
|
|
|
|
void on_event(const sapp_event* ev) {
|
|
if (ev->type == SAPP_EVENTTYPE_FILES_DROPPED) {
|
|
|
|
// the mouse position where the drop happened
|
|
float x = ev->mouse_x;
|
|
float y = ev->mouse_y;
|
|
|
|
// get the number of files and their paths like this:
|
|
const int num_dropped_files = sapp_get_num_dropped_files();
|
|
for (int i = 0; i < num_dropped_files; i++) {
|
|
const char* path = sapp_get_dropped_file_path(i);
|
|
...
|
|
}
|
|
}
|
|
}
|
|
|
|
The returned file paths are UTF-8 encoded strings.
|
|
|
|
You can call sapp_get_num_dropped_files() and sapp_get_dropped_file_path()
|
|
anywhere, also outside the event handler callback, but be aware that the
|
|
file path strings will be overwritten with the next drop operation.
|
|
|
|
In any case, sapp_get_dropped_file_path() will never return a null pointer,
|
|
instead an empty string "" will be returned if the drag'n'drop feature
|
|
hasn't been enabled, the last drop-operation failed, or the file path index
|
|
is out of range.
|
|
|
|
Drag'n'drop caveats:
|
|
|
|
- if more files are dropped in a single drop-action
|
|
than sapp_desc.max_dropped_files, the additional
|
|
files will be silently ignored
|
|
- if any of the file paths is longer than
|
|
sapp_desc.max_dropped_file_path_length (in number of bytes, after UTF-8
|
|
encoding) the entire drop operation will be silently ignored (this
|
|
needs some sort of error feedback in the future)
|
|
- no mouse positions are reported while the drag is in
|
|
process, this may change in the future
|
|
|
|
Drag'n'drop on HTML5/WASM:
|
|
|
|
The HTML5 drag'n'drop API doesn't return file paths, but instead
|
|
black-box 'file objects' which must be used to load the content
|
|
of dropped files. This is the reason why sokol_app.h adds two
|
|
HTML5-specific functions to the drag'n'drop API:
|
|
|
|
uint32_t sapp_html5_get_dropped_file_size(int index)
|
|
Returns the size in bytes of a dropped file.
|
|
|
|
void sapp_html5_fetch_dropped_file(const sapp_html5_fetch_request* request)
|
|
Asynchronously loads the content of a dropped file into a
|
|
provided memory buffer (which must be big enough to hold
|
|
the file content)
|
|
|
|
To start loading the first dropped file after an SAPP_EVENTTYPE_FILES_DROPPED
|
|
event is received:
|
|
|
|
sapp_html5_fetch_dropped_file(&(sapp_html5_fetch_request){
|
|
.dropped_file_index = 0,
|
|
.callback = fetch_cb
|
|
.buffer = {
|
|
.ptr = buf,
|
|
.size = sizeof(buf)
|
|
},
|
|
.user_data = ...
|
|
});
|
|
|
|
Make sure that the memory pointed to by 'buf' stays valid until the
|
|
callback function is called!
|
|
|
|
As result of the asynchronous loading operation (no matter if succeeded or
|
|
failed) the 'fetch_cb' function will be called:
|
|
|
|
void fetch_cb(const sapp_html5_fetch_response* response) {
|
|
// IMPORTANT: check if the loading operation actually succeeded:
|
|
if (response->succeeded) {
|
|
// the size of the loaded file:
|
|
const size_t num_bytes = response->data.size;
|
|
// and the pointer to the data (same as 'buf' in the fetch-call):
|
|
const void* ptr = response->data.ptr;
|
|
}
|
|
else {
|
|
// on error check the error code:
|
|
switch (response->error_code) {
|
|
case SAPP_HTML5_FETCH_ERROR_BUFFER_TOO_SMALL:
|
|
...
|
|
break;
|
|
case SAPP_HTML5_FETCH_ERROR_OTHER:
|
|
...
|
|
break;
|
|
}
|
|
}
|
|
}
|
|
|
|
Check the droptest-sapp example for a real-world example which works
|
|
both on native platforms and the web:

|
|
|
|
HIGH-DPI RENDERING
|
|
==================
|
|
You can set the sapp_desc.high_dpi flag during initialization to request
|
|
a full-resolution framebuffer on HighDPI displays. The default behaviour
|
|
is sapp_desc.high_dpi=false, this means that the application will
|
|
render to a lower-resolution framebuffer on HighDPI displays and the
|
|
rendered content will be upscaled by the window system composer.
|
|
|
|
In a HighDPI scenario, you still request the same window size during
|
|
sokol_main(), but the framebuffer sizes returned by sapp_width()
|
|
and sapp_height() will be scaled up according to the DPI scaling
|
|
ratio.
|
|
|
|
Note that on some platforms the DPI scaling factor may change at any
|
|
time (for instance when a window is moved from a high-dpi display
|
|
to a low-dpi display).
|
|
|
|
To query the current DPI scaling factor, call the function:
|
|
|
|
float sapp_dpi_scale(void);
|
|
|
|
For instance on a Retina Mac, returning the following sapp_desc
|
|
struct from sokol_main():
|
|
|
|
sapp_desc sokol_main() {
|
|
return (sapp_desc) {
|
|
.width = 640,
|
|
.height = 480,
|
|
.high_dpi = true,
|
|
...
|
|
};
|
|
}
|
|
|
|
...the functions the functions sapp_width(), sapp_height()
|
|
and sapp_dpi_scale() will return the following values:
|
|
|
|
sapp_width: 1280
|
|
sapp_height: 960
|
|
sapp_dpi_scale: 2.0
|
|
|
|
If the high_dpi flag is false, or you're not running on a Retina display,
|
|
the values would be:
|
|
|
|
sapp_width: 640
|
|
sapp_height: 480
|
|
sapp_dpi_scale: 1.0
|
|
|
|
If the window is moved from the Retina display to a low-dpi external display,
|
|
the values would change as follows:
|
|
|
|
sapp_width: 1280 => 640
|
|
sapp_height: 960 => 480
|
|
sapp_dpi_scale: 2.0 => 1.0
|
|
|
|
Currently there is no event associated with a DPI change, but an
|
|
SAPP_EVENTTYPE_RESIZED will be sent as a side effect of the
|
|
framebuffer size changing.
|
|
|
|
Per-monitor DPI is currently supported on macOS and Windows.
|
|
|
|
APPLICATION QUIT
|
|
================
|
|
Without special quit handling, a sokol_app.h application will quit
|
|
'gracefully' when the user clicks the window close-button unless a
|
|
platform's application model prevents this (e.g. on web or mobile).
|
|
'Graceful exit' means that the application-provided cleanup callback will
|
|
be called before the application quits.
|
|
|
|
On native desktop platforms sokol_app.h provides more control over the
|
|
application-quit-process. It's possible to initiate a 'programmatic quit'
|
|
from the application code, and a quit initiated by the application user can
|
|
be intercepted (for instance to show a custom dialog box).
|
|
|
|
This 'programmatic quit protocol' is implemented through 3 functions
|
|
and 1 event:
|
|
|
|
- sapp_quit(): This function simply quits the application without
|
|
giving the user a chance to intervene. Usually this might
|
|
be called when the user clicks the 'Ok' button in a 'Really Quit?'
|
|
dialog box
|
|
- sapp_request_quit(): Calling sapp_request_quit() will send the
|
|
event SAPP_EVENTTYPE_QUIT_REQUESTED to the applications event handler
|
|
callback, giving the user code a chance to intervene and cancel the
|
|
pending quit process (for instance to show a 'Really Quit?' dialog
|
|
box). If the event handler callback does nothing, the application
|
|
will be quit as usual. To prevent this, call the function
|
|
sapp_cancel_quit() from inside the event handler.
|
|
- sapp_cancel_quit(): Cancels a pending quit request, either initiated
|
|
by the user clicking the window close button, or programmatically
|
|
by calling sapp_request_quit(). The only place where calling this
|
|
function makes sense is from inside the event handler callback when
|
|
the SAPP_EVENTTYPE_QUIT_REQUESTED event has been received.
|
|
- SAPP_EVENTTYPE_QUIT_REQUESTED: this event is sent when the user
|
|
clicks the window's close button or application code calls the
|
|
sapp_request_quit() function. The event handler callback code can handle
|
|
this event by calling sapp_cancel_quit() to cancel the quit.
|
|
If the event is ignored, the application will quit as usual.
|
|
|
|
On the web platform, the quit behaviour differs from native platforms,
|
|
because of web-specific restrictions:
|
|
|
|
A `programmatic quit` initiated by calling sapp_quit() or
|
|
sapp_request_quit() will work as described above: the cleanup callback is
|
|
called, platform-specific cleanup is performed (on the web
|
|
this means that JS event handlers are unregisters), and then
|
|
the request-animation-loop will be exited. However that's all. The
|
|
web page itself will continue to exist (e.g. it's not possible to
|
|
programmatically close the browser tab).
|
|
|
|
On the web it's also not possible to run custom code when the user
|
|
closes a browser tab, so it's not possible to prevent this with a
|
|
fancy custom dialog box.
|
|
|
|
Instead the standard "Leave Site?" dialog box can be activated (or
|
|
deactivated) with the following function:
|
|
|
|
sapp_html5_ask_leave_site(bool ask);
|
|
|
|
The initial state of the associated internal flag can be provided
|
|
at startup via sapp_desc.html5_ask_leave_site.
|
|
|
|
This feature should only be used sparingly in critical situations - for
|
|
instance when the user would loose data - since popping up modal dialog
|
|
boxes is considered quite rude in the web world. Note that there's no way
|
|
to customize the content of this dialog box or run any code as a result
|
|
of the user's decision. Also note that the user must have interacted with
|
|
the site before the dialog box will appear. These are all security measures
|
|
to prevent fishing.
|
|
|
|
The Dear ImGui HighDPI sample contains example code of how to
|
|
implement a 'Really Quit?' dialog box with Dear ImGui (native desktop
|
|
platforms only), and for showing the hardwired "Leave Site?" dialog box
|
|
when running on the web platform:

|
|
|
|
FULLSCREEN
|
|
==========
|
|
If the sapp_desc.fullscreen flag is true, sokol-app will try to create
|
|
a fullscreen window on platforms with a 'proper' window system
|
|
(mobile devices will always use fullscreen). The implementation details
|
|
depend on the target platform, in general sokol-app will use a
|
|
'soft approach' which doesn't interfere too much with the platform's
|
|
window system (for instance borderless fullscreen window instead of
|
|
a 'real' fullscreen mode). Such details might change over time
|
|
as sokol-app is adapted for different needs.
|
|
|
|
The most important effect of fullscreen mode to keep in mind is that
|
|
the requested canvas width and height will be ignored for the initial
|
|
window size, calling sapp_width() and sapp_height() will instead return
|
|
the resolution of the fullscreen canvas (however the provided size
|
|
might still be used for the non-fullscreen window, in case the user can
|
|
switch back from fullscreen- to windowed-mode).
|
|
|
|
To toggle fullscreen mode programmatically, call sapp_toggle_fullscreen().
|
|
|
|
To check if the application window is currently in fullscreen mode,
|
|
call sapp_is_fullscreen().
|
|
|
|
WINDOW ICON SUPPORT
|
|
===================
|
|
Some sokol_app.h backends allow to change the window icon programmatically:
|
|
|
|
- on Win32: the small icon in the window's title bar, and the
|
|
bigger icon in the task bar
|
|
- on Linux: highly dependent on the used window manager, but usually
|
|
the window's title bar icon and/or the task bar icon
|
|
- on HTML5: the favicon shown in the page's browser tab
|
|
|
|
NOTE that it is not possible to set the actual application icon which is
|
|
displayed by the operating system on the desktop or 'home screen'. Those
|
|
icons must be provided 'traditionally' through operating-system-specific
|
|
resources which are associated with the application (sokol_app.h might
|
|
later support setting the window icon from platform specific resource data
|
|
though).
|
|
|
|
There are two ways to set the window icon:
|
|
|
|
- at application start in the sokol_main() function by initializing
|
|
the sapp_desc.icon nested struct
|
|
- or later by calling the function sapp_set_icon()
|
|
|
|
As a convenient shortcut, sokol_app.h comes with a builtin default-icon
|
|
(a rainbow-colored 'S', which at least looks a bit better than the Windows
|
|
default icon for applications), which can be activated like this:
|
|
|
|
At startup in sokol_main():
|
|
|
|
sapp_desc sokol_main(...) {
|
|
return (sapp_desc){
|
|
...
|
|
icon.sokol_default = true
|
|
};
|
|
}
|
|
|
|
Or later by calling:
|
|
|
|
sapp_set_icon(&(sapp_icon_desc){ .sokol_default = true });
|
|
|
|
NOTE that a completely zero-initialized sapp_icon_desc struct will not
|
|
update the window icon in any way. This is an 'escape hatch' so that you
|
|
can handle the window icon update yourself (or if you do this already,
|
|
sokol_app.h won't get in your way, in this case just leave the
|
|
sapp_desc.icon struct zero-initialized).
|
|
|
|
Providing your own icon images works exactly like in GLFW (down to the
|
|
data format):
|
|
|
|
You provide one or more 'candidate images' in different sizes, and the
|
|
sokol_app.h platform backends pick the best match for the specific backend
|
|
and icon type.
|
|
|
|
For each candidate image, you need to provide:
|
|
|
|
- the width in pixels
|
|
- the height in pixels
|
|
- and the actual pixel data in RGBA8 pixel format (e.g. 0xFFCC8844
|
|
on a little-endian CPU means: alpha=0xFF, blue=0xCC, green=0x88, red=0x44)
|
|
|
|
For instance, if you have 3 candidate images (small, medium, big) of
|
|
sizes 16x16, 32x32 and 64x64 the corresponding sapp_icon_desc struct is setup
|
|
like this:
|
|
|
|
// the actual pixel data (RGBA8, origin top-left)
|
|
const uint32_t small[16][16] = { ... };
|
|
const uint32_t medium[32][32] = { ... };
|
|
const uint32_t big[64][64] = { ... };
|
|
|
|
const sapp_icon_desc icon_desc = {
|
|
.images = {
|
|
{ .width = 16, .height = 16, .pixels = SAPP_RANGE(small) },
|
|
{ .width = 32, .height = 32, .pixels = SAPP_RANGE(medium) },
|
|
// ...or without the SAPP_RANGE helper macro:
|
|
{ .width = 64, .height = 64, .pixels = { .ptr=big, .size=sizeof(big) } }
|
|
}
|
|
};
|
|
|
|
An sapp_icon_desc struct initialized like this can then either be applied
|
|
at application start in sokol_main:
|
|
|
|
sapp_desc sokol_main(...) {
|
|
return (sapp_desc){
|
|
...
|
|
icon = icon_desc
|
|
};
|
|
}
|
|
|
|
...or later by calling sapp_set_icon():
|
|
|
|
sapp_set_icon(&icon_desc);
|
|
|
|
Some window icon caveats:
|
|
|
|
- once the window icon has been updated, there's no way to go back to
|
|
the platform's default icon, this is because some platforms (Linux
|
|
and HTML5) don't switch the icon visual back to the default even if
|
|
the custom icon is deleted or removed
|
|
- on HTML5, if the sokol_app.h icon doesn't show up in the browser
|
|
tab, check that there's no traditional favicon 'link' element
|
|
is defined in the page's index.html, sokol_app.h will only
|
|
append a new favicon link element, but not delete any manually
|
|
defined favicon in the page
|
|
|
|
For an example and test of the window icon feature, check out the the
|
|
'icon-sapp' sample on the sokol-samples git repository.
|
|
|
|
ONSCREEN KEYBOARD
|
|
=================
|
|
On some platforms which don't provide a physical keyboard, sokol-app
|
|
can display the platform's integrated onscreen keyboard for text
|
|
input. To request that the onscreen keyboard is shown, call
|
|
|
|
sapp_show_keyboard(true);
|
|
|
|
Likewise, to hide the keyboard call:
|
|
|
|
sapp_show_keyboard(false);
|
|
|
|
Note that on the web platform, the keyboard can only be shown from
|
|
inside an input handler. On such platforms, sapp_show_keyboard()
|
|
will only work as expected when it is called from inside the
|
|
sokol-app event callback function. When called from other places,
|
|
an internal flag will be set, and the onscreen keyboard will be
|
|
called at the next 'legal' opportunity (when the next input event
|
|
is handled).
|
|
|
|
OPTIONAL: DON'T HIJACK main() (#define SOKOL_NO_ENTRY)
|
|
======================================================
|
|
NOTE: SOKOL_NO_ENTRY and sapp_run() is currently not supported on Android.
|
|
|
|
In its default configuration, sokol_app.h "hijacks" the platform's
|
|
standard main() function. This was done because different platforms
|
|
have different entry point conventions which are not compatible with
|
|
C's main() (for instance WinMain on Windows has completely different
|
|
arguments). However, this "main hijacking" posed a problem for
|
|
usage scenarios like integrating sokol_app.h with other languages than
|
|
C or C++, so an alternative SOKOL_NO_ENTRY mode has been added
|
|
in which the user code provides the platform's main function:
|
|
|
|
- define SOKOL_NO_ENTRY before including the sokol_app.h implementation
|
|
- do *not* provide a sokol_main() function
|
|
- instead provide the standard main() function of the platform
|
|
- from the main function, call the function ```sapp_run()``` which
|
|
takes a pointer to an ```sapp_desc``` structure.
|
|
- from here on```sapp_run()``` takes over control and calls the provided
|
|
init-, frame-, event- and cleanup-callbacks just like in the default model.
|
|
|
|
sapp_run() behaves differently across platforms:
|
|
|
|
- on some platforms, sapp_run() will return when the application quits
|
|
- on other platforms, sapp_run() will never return, even when the
|
|
application quits (the operating system is free to simply terminate
|
|
the application at any time)
|
|
- on Emscripten specifically, sapp_run() will return immediately while
|
|
the frame callback keeps being called
|
|
|
|
This different behaviour of sapp_run() essentially means that there shouldn't
|
|
be any code *after* sapp_run(), because that may either never be called, or in
|
|
case of Emscripten will be called at an unexpected time (at application start).
|
|
|
|
An application also should not depend on the cleanup-callback being called
|
|
when cross-platform compatibility is required.
|
|
|
|
Since sapp_run() returns immediately on Emscripten you shouldn't activate
|
|
the 'EXIT_RUNTIME' linker option (this is disabled by default when compiling
|
|
for the browser target), since the C/C++ exit runtime would be called immediately at
|
|
application start, causing any global objects to be destroyed and global
|
|
variables to be zeroed.
|
|
|
|
WINDOWS CONSOLE OUTPUT
|
|
======================
|
|
On Windows, regular windowed applications don't show any stdout/stderr text
|
|
output, which can be a bit of a hassle for printf() debugging or generally
|
|
logging text to the console. Also, console output by default uses a local
|
|
codepage setting and thus international UTF-8 encoded text is printed
|
|
as garbage.
|
|
|
|
To help with these issues, sokol_app.h can be configured at startup
|
|
via the following Windows-specific sapp_desc flags:
|
|
|
|
sapp_desc.win32_console_utf8 (default: false)
|
|
When set to true, the output console codepage will be switched
|
|
to UTF-8 (and restored to the original codepage on exit)
|
|
|
|
sapp_desc.win32_console_attach (default: false)
|
|
When set to true, stdout and stderr will be attached to the
|
|
console of the parent process (if the parent process actually
|
|
has a console). This means that if the application was started
|
|
in a command line window, stdout and stderr output will be printed
|
|
to the terminal, just like a regular command line program. But if
|
|
the application is started via double-click, it will behave like
|
|
a regular UI application, and stdout/stderr will not be visible.
|
|
|
|
sapp_desc.win32_console_create (default: false)
|
|
When set to true, a new console window will be created and
|
|
stdout/stderr will be redirected to that console window. It
|
|
doesn't matter if the application is started from the command
|
|
line or via double-click.
|
|
|
|
MEMORY ALLOCATION OVERRIDE
|
|
==========================
|
|
You can override the memory allocation functions at initialization time
|
|
like this:
|
|
|
|
void* my_alloc(size_t size, void* user_data) {
|
|
return malloc(size);
|
|
}
|
|
|
|
void my_free(void* ptr, void* user_data) {
|
|
free(ptr);
|
|
}
|
|
|
|
sapp_desc sokol_main(int argc, char* argv[]) {
|
|
return (sapp_desc){
|
|
// ...
|
|
.allocator = {
|
|
.alloc_fn = my_alloc,
|
|
.free_fn = my_free,
|
|
.user_data = ...,
|
|
}
|
|
};
|
|
}
|
|
|
|
If no overrides are provided, malloc and free will be used.
|
|
|
|
This only affects memory allocation calls done by sokol_app.h
|
|
itself though, not any allocations in OS libraries.
|
|
|
|
|
|
ERROR REPORTING AND LOGGING
|
|
===========================
|
|
To get any logging information at all you need to provide a logging callback in the setup call
|
|
the easiest way is to use sokol_log.h:
|
|
|
|
#include "sokol_log.h"
|
|
|
|
sapp_desc sokol_main(int argc, char* argv[]) {
|
|
return (sapp_desc) {
|
|
...
|
|
.logger.func = slog_func,
|
|
};
|
|
}
|
|
|
|
To override logging with your own callback, first write a logging function like this:
|
|
|
|
void my_log(const char* tag, // e.g. 'sapp'
|
|
uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info
|
|
uint32_t log_item_id, // SAPP_LOGITEM_*
|
|
const char* message_or_null, // a message string, may be nullptr in release mode
|
|
uint32_t line_nr, // line number in sokol_app.h
|
|
const char* filename_or_null, // source filename, may be nullptr in release mode
|
|
void* user_data)
|
|
{
|
|
...
|
|
}
|
|
|
|
...and then setup sokol-app like this:
|
|
|
|
sapp_desc sokol_main(int argc, char* argv[]) {
|
|
return (sapp_desc) {
|
|
...
|
|
.logger = {
|
|
.func = my_log,
|
|
.user_data = my_user_data,
|
|
}
|
|
};
|
|
}
|
|
|
|
The provided logging function must be reentrant (e.g. be callable from
|
|
different threads).
|
|
|
|
If you don't want to provide your own custom logger it is highly recommended to use
|
|
the standard logger in sokol_log.h instead, otherwise you won't see any warnings or
|
|
errors.
|
|
|
|
|
|
TEMP NOTE DUMP
|
|
==============
|
|
- onscreen keyboard support on Android requires Java :(, should we even bother?
|
|
- sapp_desc needs a bool whether to initialize depth-stencil surface
|
|
- GL context initialization needs more control (at least what GL version to initialize)
|
|
- application icon
|
|
- the Android implementation calls cleanup_cb() and destroys the egl context in onDestroy
|
|
at the latest but should do it earlier, in onStop, as an app is "killable" after onStop
|
|
on Android Honeycomb and later (it can't be done at the moment as the app may be started
|
|
again after onStop and the sokol lifecycle does not yet handle context teardown/bringup)

NOTE:
|
|
|
|
Q: Why not use CAMetalDrawable.presentedTime on macOS and iOS?
|
|
A: The value appears to be highly unstable during the first few
|
|
seconds, sometimes several frames are dropped in sequence, or
|
|
switch between 120 and 60 Hz for a few frames. Simply measuring
|
|
and averaging the frame time yielded a more stable frame duration.
|
|
Maybe switching to CVDisplayLink would yield better results.
|
|
Until then just measure the time.
