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.
|
|
|
|
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_GLES2
|
|
#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_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.
|
|
|
|
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.
|
|
|
|
To make use of the integrated GL loader, simply include the sokol_app.h
|
|
implementation before the sokol_gfx.h implementation.
|
|
|
|
For example code, see https://github.com/floooh/sokol-samples/tree/master/sapp

|
|
|
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.

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 (TODO: 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 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.
|
|
.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 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_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 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.
|
|
|
|
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
|
|
27 == SG_PIXELFORMAT_BGRA8
|
|
41 == SG_PIXELFORMAT_DEPTH
|
|
42 == SG_PIXELFORMAT_DEPTH_STENCIL
|
|
|
|
int sapp_sample_count(void)
|
|
Return the MSAA sample count 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 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
|
|
|
|
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 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_EVENTYTPE_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
|
|
cgltf-sapp.c sample in the sokol-samples repository
|
|
at https://github.com/floooh/sokol-samples):
|
|
|
|
static void input(const sapp_event* ev) {
|
|
switch (ev->type) {
|
|
case SAPP_EVENTTYPE_MOUSE_DOWN:
|
|
if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) {
|
|
sapp_lock_mouse(true);
|
|
}
|
|
break;
|
|
|
|
case SAPP_EVENTTYPE_MOUSE_UP:
|
|
if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) {
|
|
sapp_lock_mouse(false);
|
|
}
|
|
break;
|
|
|
|
case SAPP_EVENTTYPE_MOUSE_MOVE:
|
|
if (sapp_mouse_locked()) {
|
|
cam_orbit(&state.camera, ev->mouse_dx * 0.25f, ev->mouse_dy * 0.25f);
|
|
}
|
|
break;
|
|
|
|
default:
|
|
break;
|
|
}
|
|
}
|
|
|
|
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
|
|
|
|
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 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 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.
|
|
|
|
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 brower 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().
|
|
|
|
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
|
|
- 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)
