Hide buttons from titlebar in Cocoa
I believe this should work:
[[window standardWindowButton:NSWindowCloseButton] setHidden:YES];
[[window standardWindowButton:NSWindowMiniaturizeButton] setHidden:YES];
[[window standardWindowButton:NSWindowZoomButton] setHidden:YES];
another way is...
for (id subview in [self window].contentView.superview.subviews) {
if ([subview isKindOfClass:NSClassFromString(@"NSTitlebarContainerView")]) {
NSView *titlebarView = [subview subviews][0];
for (id button in titlebarView.subviews) {
if ([button isKindOfClass:[NSButton class]]) {
[button setHidden:YES];
}
}
}
}
Swift code for accepted answer
window!.standardWindowButton(.miniaturizeButton)!.isHidden = true
window!.standardWindowButton(.zoomButton)!.isHidden = true
window!.standardWindowButton(.closeButton)!.isHidden = true
I also needed this but visible for mouse overs - Swift:
var trackingTag: NSTrackingRectTag?
override func mouseEntered(with theEvent: NSEvent) {
if trackingTag == theEvent.trackingNumber {
window!.standardWindowButton(.closeButton)!.alphaValue = 1.00
}
}
override func mouseExited(with theEvent: NSEvent) {
if trackingTag == theEvent.trackingNumber {
window!.standardWindowButton(.closeButton)!.alphaValue = 0.01
}
}
func updateTrackingAreas(_ establish : Bool) {
if let tag = trackingTag {
window!.standardWindowButton(.closeButton)!.removeTrackingRect(tag)
}
if establish, let closeButton = window!.standardWindowButton(.closeButton) {
trackingTag = closeButton.addTrackingRect(closeButton.bounds, owner: self, userData: nil, assumeInside: false)
}
}
override func windowDidLoad() {
window!.ignoresMouseEvents = false
updateTrackingAreas(true)
window!.standardWindowButton(.closeButton)!.alphaValue = 0.01
}
func windowShouldClose(_ sender: Any) -> Bool {
window!.ignoresMouseEvents = true
updateTrackingAreas(false)
return true
}
Visibility is needed but just slightly - 0.01 opacity, to have the tracking area effective.
