Windows

These functions are declared in the following header file:

 #include <allegro5/allegro_windows.h>

al_get_win_window_handle

HWND al_get_win_window_handle(ALLEGRO_DISPLAY *display)

Source Code

Returns the handle to the window that the passed display is using.

al_win_add_window_callback

bool al_win_add_window_callback(ALLEGRO_DISPLAY *display,
   bool (*callback)(ALLEGRO_DISPLAY *display, UINT message, WPARAM wparam,
   LPARAM lparam, LRESULT *result, void *userdata), void *userdata)

Source Code

The specified callback function will intercept the window's message before Allegro processes it. If the callback function consumes the event, then it should return true. In that case, Allegro will not do anything with the event.

Optionally, you may use result to customize what Allegro will return return in response to this event. By default, Allegro returns TRUE.

The userdata pointer can be used to supply additional context to the callback function.

The callbacks are executed in the same order they were added.

Returns true if the callback was added.

Since: 5.1.2

al_win_remove_window_callback

bool al_win_remove_window_callback(ALLEGRO_DISPLAY *display,
   bool (*callback)(ALLEGRO_DISPLAY *display, UINT message, WPARAM wparam,
   LPARAM lparam, LRESULT *result, void *userdata), void *userdata)

Source Code

Removes the callback that was previously registered with al_win_add_window_callback. The userdata pointer must be the same as what was used during the registration of the callback.

Returns true if the callback was removed.
