I wish to have one column of my outline view dedicated to switch buttons, and when this column is clicked, the item should NOT be selected (as in iTunes), unfortunately I have not found a way to do it.
I tried this hacky solution, but my outlineView:shouldSelectItem: selector is called twice for each mouse down, causing the item to be toggled twice. Any help?
- (BOOL)outlineView:(NSOutlineView *)outlineView shouldSelectItem:(id)item
NSEvent *theEvent = [NSApp currentEvent];
if([theEvent type] == NSLeftMouseDown)
NSPoint p = [outlineView convertPoint:[theEvent locationInWindow] fromView:nil];
NSRect r = [outlineView rectOfColumn:0];
[item setEnabled:([item enabled] ? NO : YES)];
