freeze_mouse_flag(3alleg4)					  Allegro manual					freeze_mouse_flag(3alleg4)

NAME
freeze_mouse_flag - Flag to avoid redrawing the mouse pointer. Allegro game programming library. SYNOPSIS
#include <allegro.h> extern volatile int freeze_mouse_flag; DESCRIPTION
If this flag is set, the mouse pointer won't be redrawn when the mouse moves. This can avoid the need to hide the pointer every time you draw to the screen, as long as you make sure your drawing doesn't overlap with the current pointer position. SEE ALSO

NAME
show_mouse - Tells Allegro to display a mouse pointer on the screen. SYNOPSIS
#include <allegro.h> void show_mouse(BITMAP *bmp); DESCRIPTION
Tells Allegro to display a mouse pointer on the screen. This will only work if the timer module has been installed. The mouse pointer will be drawn onto the specified bitmap, which should normally be `screen' (see later for information about bitmaps). To hide the mouse pointer, call show_mouse(NULL). Warning: if you draw anything onto the screen while the pointer is visible, a mouse movement interrupt could occur in the middle of your drawing operation. If this happens the mouse buffering and graphics drawing code will get confused and will leave 'mouse droppings' all over the screen. To prevent this, you must make sure you turn off the mouse pointer whenever you draw onto the screen. This is not needed if you are using a hardware cursor. Note: you must not be showing a mouse pointer on a bitmap at the time that the bitmap is destroyed with destroy_bitmap(), e.g. call show_mouse(NULL); before destroying the bitmap. This does not apply to `screen' since you never destroy `screen' with destroy_bitmap(). SEE ALSO
