NAME
SetWindowPointerA -- Select a pointer for your window. (V39)
SetWindowPointer -- Varargs stub for SetWindowPointerA(). (V39)
SYNOPSIS
SetWindowPointerA( window, taglist )
A0 A1
VOID SetWindowPointerA( struct window *, struct tagitem * );
SetWindowPointer( window, tag1, ... )
VOID SetWindowPointer( struct window *, ulong tag1, ... );
FUNCTION
Allows you to set the pointer image associated with the
specified window. Whenever the window is the active one,
the pointer image will change to the window's version.
If the window is the active one when this routine is
called, the change takes place immediately.
INPUTS
window = pointer to the window to receive this pointer definition
taglist = pointer to a taglist describing your pointer
TAGS
The same three tags are also accepted by openwindowtaglist(),
which allows you to establish the initial pointer at the
time you open your window.
WA_Pointer (APTR) - The pointer you wish to associate with
your window. If NULL, you are requesting the preferences
default pointer. custom pointers should be allocated
by performing a newobject() on "pointerclass".
(See <intuition/pointerclass.h>). Defaults to NULL.
WA_BusyPointer (BOOL) - Set to TRUE to request the preferences
busy-pointer. If FALSE, your pointer will be as requested
by WA_Pointer. Defaults to FALSE.
WA_PointerDelay (BOOL) - Set to TRUE to defer changing your
pointer for a brief instant. This is typically used
along with setting the busy pointer, especially when
the application knows it may be busy for a very short
while. If the application clears the pointer or sets
another pointer before the delay expires, the pending
pointer change is cancelled. This reduces short
flashes of the busy pointer.
RESULT
None
EXAMPLE
This example sets the standard busy pointer with pointer-delay,
does a bit of work, then clears the pointer:
/* Put up the busy pointer, with pointer-delay */
SetWindowPointer( win,
WA_BusyPointer, TRUE,
WA_PointerDelay, TRUE,
TAG_DONE );
/* Do busy stuff here */
/* No tags means "clear the pointer" */
SetWindowPointer( win,
TAG_DONE );
