Hi list, I experience some strange behavior with NSSplitView.
Let me explain what I'm trying to do : The split view contains 3 subviews (2 dividers), and has a delegate that controls it. It is an horizontal split view. Let number those 3 views from top to bottom 0, 1 and 2. The upper divider has the default behavior, the two upper views (0 & 1) should be resized. I want the lower divider to behave differently, when dragged, view 1 should not resize but instead views 0 & 2 should. So, to achieve this, I implemented delegate methods : -(void)splitViewDidResizeSubviews:(NSNotification *)notif; -(void)splitViewWillResizeSubviews:(NSNotification *)notif; In those methods, I inspect the userInfo dictionary, in order to react only when the divider n°1 is dragged. In the first method, I record the position of divider 0, as well as the height of the third view : _positionZero = NSHeight([view0 frame]); _view2Height = NSHeight([view2 frame]); In the second, I compute the difference between view2 successive heights, and then move divider 0 by the same amount : CGFloat view2HeightDelta = _view2Height - NSHeight([view2 frame]); [[self splitView] setPosition:(_positionZero + view2Height) ofDividerAtIndex:0]; // view2Height maybe positive or negative Now, what happens ? When I drag divider 1 down, all works as expected. When I drag it up, it stops moving at what appears to be the return value of -minPossiblePositionOfDividerAtIndex, for divider 0. This shouldn't happen, as the min possible position is updated after the call to -setPosition:ofDividerAtIndex:, which is confirmed by my logs. But the divider stops moving at this limit, as if the split view was looking only one time to this minimum, and never again (until I release the mouse and then drag the divider again). Anyone experienced something like this ? Is there a better way to do what I'm trying to do ? Any answer/advice is greatly appreciated.
