Hi All, I want to set NSSegmentStyleSeparated on my NSSegmentedControl (managed by autolayout). However, when I create constraints for the parent view, I get an exception:
Assertion failure in -[NSSegmentedControl ns_widgetType], /SourceCache/AppKit/AppKit-1348.17/Layout.subproj/NSUserInterfaceTheme.m:398 An uncaught exception was raised What kind of segmented control are we! Example code: (in WindowController) - (void)windowDidLoad { [super windowDidLoad]; NSSegmentedControl* segmentedControl = [[NSSegmentedControl alloc] init]; [segmentedControl setSegmentCount:2]; [segmentedControl setTranslatesAutoresizingMaskIntoConstraints:NO]; segmentedControl.segmentStyle = NSSegmentStyleSeparated; [self.window.contentView addSubview:segmentedControl]; NSString* constraint = @"|-[segmentedControl]-|"; NSDictionary* views = NSDictionaryOfVariableBindings(segmentedControl); NSArray* constraints = [NSLayoutConstraint constraintsWithVisualFormat:constraint options:NSLayoutFormatDirectionLeadingToTrailing metrics:nil views:views]; [self.window.contentView addConstraints:constraints]; } The exception is raised in "addConstraints:". Everything is fine if I do not change segmentStyle. It also works fine if I change segment style *after* adding constraints, but then I get the exception e.g. when dragging window to external display. Any ideas? Thanks for any help.
