One of the benefits of using New Window() is the ability to add optional scripts to display boxes. In the deprecated Dialog(), the following combo box could not include an optional script. If you wanted an action associated with any of the display box controls, you had to place a script as the control’s last argument. For example:
win = New Window( "Combo Box",
<<Modal,
<<ReturnResult,
	comboObj = Combo Box(
		{"True", "False"},
		<< Set( 1 ),
		Print( comboObj << Get )
	)
);
