Create an NSButton using a CGRect to define its frame:
var button = NSButton(frame: CGRect(x: 100, y: 100, width: 80, height: 30))
Call setbuttonType: using a value from the NSButtonType enumeration. The default style is MomentaryPushInButton:
button.setButtonType(NSButtonType.MomentaryLightButton)
Set the title property to change the text displayed on the button:
button.title = "Click Me!"
The NSButton class uses the target/action pattern to indicate when the button has been clicked. Set the target to the object that is going to handle the click event. Then use a Selector to set the action property:
button.target = self
button.action = Selector("buttonClicked:")
Next, add the button to the window’s contentView property:
self.window.contentView.addSubview(button)
Finally, implement the action method to handle the button click:
func buttonClicked( sender : NSButton ) {
println("Button clicked")
}
