If I want to setFrameOrigin: (or setFrame:) correctly

while keeping old rotation angle, I must keep the old

angle first, then set frame rotation to 0, then set origin

then set frame rotation to old angle.



This code will let the button rotate and move the frame.

But it doesn't work properly on GNUstep but Cocoa.

(you may want to keep calling it a few times to produce

the unexpected result)



- (void) buttonPush:(id)sender

{



                float oldAngle = [aView frameRotation];

                [aView setFrameRotation:oldAngle + 10];



                NSRect oldRect = [aView frame];

                [aView setFrame:NSOffsetRect(oldRect,10,10)];

        [[aView superview] setNeedsDisplay:YES];

}



a small workaround can fix it.



- (void) buttonPush:(id)sender

{



                float oldAngle = [aView frameRotation];

                [aView setFrameRotation:oldAngle + 10];



                NSRect oldRect = [aView frame];



                [aView setFrameRotation:0]; //hack1



                [aView setFrame:NSOffsetRect(oldRect,10,10)];



                [aView setFrameRotation:oldAngle + 10]; //hack2



        [[aView superview] setNeedsDisplay:YES];

}
