[alt.toolkits.xview] Is explicit dispatching only for "output"?

andrew@resam.dk (Leif Andrew Rump) (03/20/91)

The code below, which is part of a Guide generated XView program
with two buttons does not perform as expected and documented in
Volume Seven of XView Programming Manual (Version 2) page 399.

The second paragraph on page 399 states: "... the user might be
attempting to interact with the application by selecting a panel
button." which is exactly what we want. After activating the
Search button the user should be able to press the Stop button.

Which (s)he isn't!

/*
 * Notify callback function for `search_but'.
 */
void fs_search_notify(item, event)
Panel_item      item;
Event           *event;
{
  Display	*dpy;
  
  dpy = (Display *)xv_get(fs_popup_win->popup_win, XV_DISPLAY);
  fs_stop_search = false;

  XFlush(dpy);
  while (!fs_stop_search)
  {
    notify_dispatch();
    XFlush(dpy);

    Odin_search_batch(...);	/* This returns every now and then */
  }
}
 
/*
 * Notify callback function for `stop_but'.
 */
void fs_stop_notify(item, event)
Panel_item      item;
Event           *event;
{
  fs_stop_search = true;
}
