NSWindow resize issue

[Andreas Höschler]

Hi all,

while working on GSDock I encountered a window resize problem that does 
only occur under GNUstep. The application works as expected under 
MacOSX, but under GNUstep there seems to be some kind of update problem 
when the dock window and contentView is resized.

I encounter this problem when I first start GSDock and then any other 
GNUstep application. The dock should be resized to hold the additional 
icon. The relevant portion of code is here:

- (void)resizeDock
{
...
    frameRect.size.width = cellSize.width;
    frameRect.size.height = cellSize.height * [self numberOfRows];

    NSLog(@"numberOfRows %d", [self numberOfRows]);
    NSLog(@"frameRect.size %@", NSStringFromSize(frameRect.size));

    [[self window] setFrame: frameRect display:NO animate:NO];
    [self setCellSize: cellSize];
    [self setNeedsDisplay:YES];
    NSLog(@"window %@", NSStringFromRect([[self window] frame]));
    NSLog(@"dock %@", NSStringFromRect([self frame]));
}

The logs show the correct new size but the display is not refreshed 
accordingly. Can anybody confirm this behaviour/problem on his 
machine/installation?

I am just getting lost in back trying to figure out how this is 
supposed to work. I suspect the responsible piece of code to be in

        pico ./back/Source/x11/XGServerWindow.m

        - (void)placewindow:(NSRect)rect :(int)win;

but I would appreciate to hear that this happens on other 
machines/installations as well before I get any deeper into the water. 
I have attached the GSDock sources.

Thanks a lot!

Regards,

  Andreas
