ShowCursor

ShowCursor Display the mouse cursor

#include <Quickdraw.h> Quickdraw

void ShowCursor( );

This function increments the cursor level (but never higher than 0). If the

cursor level gets to 0, the cursor is displayed and resumes tracking the mouse.

Notes: Each call to ShowCursor should balance a previous call to HideCursor

or ShieldCursor.

This call increments the cursor level. The cursor level is set to 0 when

you call InitCursor; is decremented by each call to HideCursor; and

incremented by each call to ShowCursor. The cursor is visible only when

the cursor level is at 0. The system never increments the cursor level

above 0, so additional call to ShowCursor have no effect.

An alternative to the HideCursor...ShowCursor sequence is

ShieldCursor ... ShowCursor, which hides the cursor only if it is

currently positioned within a specified rectangle.
