I have an NSplitview similar to Mails. I'm trying to fix the split so it doesn't move just like Mail but can't for the life of me figure out how to do it. My left split has an Outlineview and the right split a tableview. Resizing the window always moves the split upsetting the visual appearance of the sourcelist in the left split.
You can do this by implementing the resizeSubviewsWithOldSize delegate method, here is what I do. I have 2 views left is flexible in width, right has fixed width.
- (void)splitView:(NSSplitView *)sender resizeSubviewsWithOldSize: (NSSize)oldSize
{
NSRect newFrame = [sender frame];
CGFloat dt = [sender dividerThickness];
// this is the fixed view (right)
// on top on being fixed it is also collapsible
NSRect rightFrame = [rightView frame];
// this is the flexible view (left)
NSRect leftFrame = [leftView frame];
rightFrame.size.height = newFrame.size.height;
leftFrame.size.height = newFrame.size.height;
if (![splitView isSubviewCollapsed:rightView]) {
rightFrame.origin.x = newFrame.size.width -
rightFrame.size.width;
rightFrame.origin.y = 0;
leftFrame.origin = NSMakePoint(0,0);
leftFrame.size.width = newFrame.size.width -
rightFrame.size.width - dt;
} else {
rightFrame.origin.x = newFrame.size.width;
rightFrame.origin.y = 0;
rightFrame.size.width = 0;
leftFrame.origin = NSMakePoint(0,0);
leftFrame.size.width = newFrame.size.width - dt;
}
[leftView setFrame: leftFrame];
[rightView setFrame:rightFrame];
}
The code above is a little modified from what I actually use and I
didn't compile it so it might need change. Also it can be condensed
considerably. Also note that you may need to implement
canCollapseSubview, constrainMaxCoordinate and constrainMinCoordinate
depending on what exactly you're trying to achieve.
The main disadvantage when doing this (as far as I can see) is that you're responsible for correctly setting up all the child view frames. The split view prints debug logs when you do something that is completely wrong, so that helps.
