sokol_app.h -- cross-platform application wrapper
Project URL: https://github.com/floooh/sokol
Do this:
#define SOKOL_IMPL
before you include this file in *one* C or C++ file to create the
implementation.
Optionally provide the following defines with your own implementations:
SOKOL_ASSERT(c) - your own assert macro (default: assert(c))
SOKOL_LOG(msg) - your own logging function (default: puts(msg))
SOKOL_UNREACHABLE() - a guard macro for unreachable code (default: assert(false))
SOKOL_ABORT() - called after an unrecoverable error (default: abort())
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_API_DECL - public function declaration prefix (default: extern)
SOKOL_API_IMPL - public function implementation prefix (default: -)
SOKOL_CALLOC - your own calloc function (default: calloc(n, s))
SOKOL_FREE - your own free function (default: free(p))
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_API_DECL as __declspec(dllexport)
or __declspec(dllimport) as needed.
Portions of the Windows and Linux GL initialization and event code have been
taken from GLFW (http://www.glfw.org/)
iOS onscreen keyboard support 'inspired' by libgdx.
If you use sokol_app.h together with sokol_gfx.h, include both headers
in the implementation source file, and include sokol_app.h before
sokol_gfx.h since sokol_app.h will also include the required 3D-API
headers.
On Windows, a minimal 'GL header' and function loader is integrated which
contains just enough of GL for sokol_gfx.h. If you want to use your own
GL header-generator/loader instead, define SOKOL_WIN32_NO_GL_LOADER
before including the implementation part of sokol_app.h.
For example code, see https://github.com/floooh/sokol-samples/tree/master/sapp
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, Android (RaspberryPi)
- 3D-APIs: Metal, D3D11, GL3.2, GLES2, 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,
...
};
}
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).
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 in the
future may also be 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.
.fail_cb (void (*)(const char* msg))
The fail callback is called when a fatal error is encountered
during start which doesn't allow the program to continue.
Providing a callback here gives you a chance to show an error message
to the user. The default behaviour is SOKOL_LOG(msg)
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 you're allergic to global variables
or cannot use them for other reasons, an alternative set of callbacks
can be defined in sapp_desc, together with a user_data pointer:
.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_cb (void(*)(const sapp_event* event, void* user_data))
.fail_cb (void(*)(const char* msg, void* user_data))
These are the user-data versions of the callback functions. You
can mix those with the standard callbacks that don't have the
user_data argument.
The function sapp_userdata() can be used to query the user_data
pointer provided in the sapp_desc struct.
You can 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)
Returns the current width of the default framebuffer, this may change
from one frame to the next.
int sapp_height(void)
Likewise, returns the current height of the default framebuffer.
bool sapp_gles2(void)
Returns true if a GLES2 or WebGL context has been created. This
is useful when a GLES3/WebGL2 context was requested but is not
available so that sokol_app.h had to fallback to GLES2/WebGL.
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 an ARC __bridge cast so that
they 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 an 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 an 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_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
--- 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
called on the web and mobile platforms.
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. You can also get a DPI scaling factor with the function
sapp_dpi_scale().
Here's an example on a Mac with Retina display:
sapp_desc sokol_main() {
return (sapp_desc) {
.width = 640,
.height = 480,
.high_dpi = true,
...
};
}
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
APPLICATION QUIT
================
Without special quit handling, a sokol_app.h application will exist
'gracefully' when the user clicks the window close-button. 'Graceful
exit' means that the application-provided cleanup callback will be
called.
This 'graceful exit' is only supported on native desktop platforms, on
the web and mobile platforms an application may be terminated at any time
by the user or browser/OS runtime environment without a chance to run
custom shutdown code.
On the web platform, you can call the following function to let the
browser open a standard popup dialog before the user wants to leave a site:
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.
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 trough 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.
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:
https://floooh.github.io/sokol-html5/wasm/imgui-highdpi-sapp.html
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).
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)
======================================================
In its default configuration, sokol_app.h "hijacks" the platform's
standard main() function. This was done because different platforms
have different main functions 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.
- ```sapp_run()``` takes over control and calls the provided init-, frame-,
shutdown- and event-callbacks just like in the default model, it
will only return when the application quits (or not at all on some
platforms, like emscripten)
NOTE: SOKOL_NO_ENTRY is currently not supported on Android.
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
- mouse pointer visibility(?)
- the UPDATE_CURSOR event currently behaves differently between Win32 and OSX
(Win32 sends the event each frame when the mouse moves and is inside the window
client area, OSX sends it only once when the mouse enters the client area)
- 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)
