- All requesters in the Requester Toolkit check the pr_WindowPtr of your
- process to find the screen they should open on.
-
- These code fragments show you how to set/restore the pr_WindowPtr of your
- process.
-
- -----------------------------------------------------------------------------
-
- ...
- struct Window *win;
- struct Process *myproc;
- APTR oldwinptr;
-
- main()
- {
- myproc = (struct Process *)FindTask (NULL);
- /* get old window pointer */
- oldwinptr = myproc->pr_WindowPtr;
- ...
- /* Open your screen */
- ...
- /* Open window on your screen */
- win = OpenWindow (&newwindow);
- if (!win) FreeExit();
- /* change the window pointer */
- myproc->pr_WindowPtr = win;
- ...
- /* now all requesters from the Requester Toolkit will appear
- on the screen your window is on. */
- ...
- }
-
- -----------------------------------------------------------------------------
- In 'FreeExit()' you MUST restore the old windowptr before closing your
- window and exiting!
- -----------------------------------------------------------------------------
-
- FreeExit()
- {
- ...
- /* restore old window pointer before closing window */
- myproc->pr_WindowPtr = oldwinptr;
- if (win) CloseWindow (win);
- ...
- exit (0);
- }
