Re: [fix] Lost of menubar in 'full screen on' mode - Squeak-dev

6 May 1999


      This fix is for Mac Squeak source 'sqMacWindow.c', when in 'full screen on'
mode if you switch to other application with Command-Tab you lost the
menubar, this is because the VM is not processing the suspend/resume event.
Add this lines in function HandleEvents(void):
case osEvt:		/* this restore menubar in suspendMessage. JDR. */
    switch ((theEvent.message >> 24) & 0x0FF) { /* high byte of message */
    	Boolean		gInBackground;
case suspendResumeMessage:
    		/* suspend/resume is also an activate/deactivate */
    		gInBackground = (theEvent.message & resumeFlag) == 0;
    		if (fullScreenFlag)	{
    			if (gInBackground)	{
    				MenuBarRestore();
    			}
    			else
    			{
    				MenuBarHide();
    			}
    		}
    	break;
    }
break;
Also the function MenuBarRestore is incomplete, needs to be:
void MenuBarRestore(void) {
  /* Restore the menu bar from its saved state. Do nothing if it isn''t
hidden. */
  /* Many thanks to John McIntosh for this code!! */
    WindowPtr	win;
if (menuBarRegion == nil) return;  /* no saved state, so menu bar
is not hidden */
    DiffRgn(LMGetGrayRgn(), menuBarRegion, LMGetGrayRgn());
    LMSetMBarHeight(menuBarHeight);
win = FrontWindow();	/* to restore menubar in suspendMessage.
JDR. */
    if (win)	{
    	CalcVis(win);
    	CalcVisBehind(win, menuBarRegion);
    }
    HiliteMenu(0);
DisposeRgn(menuBarRegion);
    menuBarRegion = nil;
    DrawMenuBar();
}
Finally the SIZE flag 'acceptSuspendResumeEvents' needs to be activated in
the CW proyect.
