#include <allegro5/allegro.h> void al_apply_window_constraints(ALLEGRO_DISPLAY *display, bool onoff)
If enabled, the specified display will be automatically resized to new sizes to conform constraints in next cases:
- The specified display is resizable, not maximized and is not in fullscreen mode.
- If the appropriate current display size (width or height) is less than the value of constraint. Applied to minimum constraints.
- If the appropriate current display size (width or height) is greater than the value of constraint. Applied to maximum constraints.
Constrains are not applied when a display is toggle from windowed to maximized or fullscreen modes. When a display is toggle from maximized/fullscreen to windowed mode, then the display may be resized as described above. The later case is also possible when a user drags the maximized display via mouse.
If disabled, the specified display will stop using constraints.
