Function Documentation

void GrDestroyCursor (  GR_CURSOR_ID  cid  )

Destroys the specified server-based cursor and reclaims the memory used by it. Parameters: cid  ID of the cursor to destory

void GrMoveCursor (  GR_COORD  x, GR_COORD  y )

Moves the cursor (mouse pointer) to the specified coordinates. The coordinates are relative to the root window, where (0,0) is the upper left hand corner of the screen. The reference point used for the pointer is that of the "hot spot". After moving the pointer, the graphic used for the pointer will change to the graphic defined for use in the window which it is over. Parameters: x  the X coordinate to move the pointer to y  the Y coordinate to move the pointer to

GR_CURSOR_ID GrNewCursor (  GR_SIZE  width, GR_SIZE  height, GR_COORD  hotx, GR_COORD  hoty, GR_COLOR  foreground, GR_COLOR  background, GR_BITMAP *  fgbitmap, GR_BITMAP *  bgbitmap )

Creates a server-based cursor (mouse graphic) resource. Parameters: width  the width of the pointer bitmap height  the height of the pointer bitmap hotx  the X coordinate within the bitmap used as the target of the pointer hoty  the Y coordinate within the bitmap used as the target of the pointer foreground  the colour to use for the foreground of the pointer background  the colour to use for the background of the pointer fgbitmap  pointer to bitmap data specifying the foreground of the pointer bgbitmap  pointer to bitmap data specifying the background of the pointer

void GrSetWindowCursor (  GR_WINDOW_ID  wid, GR_CURSOR_ID  cid )

Specify a cursor for a window. This cursor will only be used within that window, and by default for its new children. If the cursor is currently within this window, it will be changed to the new one immediately. If the new cursor ID is 0, revert to the root window cursor. Parameters: wid  the ID of the window to set the cursor for cid  the cursor ID
