		Standard themed Button.
	</brief_description>
	<description>
		Button is the standard themed button. It can contain text and an icon, and will display them according to the current [Theme].
		[b]Example of creating a button and assigning an action when pressed by code:[/b]
		[codeblock]
		func _ready():
		    var button = Button.new()
		    button.text = "Click me"
		    button.connect("pressed", self, "_button_pressed")
		    add_child(button)

		func _button_pressed():
		    print("Hello world!")
		[/codeblock]
		Buttons (like all Control nodes) can also be created in the editor, but some situations may require creating them from code.
		See also [BaseButton] which contains common properties and methods associated with this node.
		[b]Note:[/b] Buttons do not interpret touch input and therefore don't support multitouch, since mouse emulation can only press one button at a given time. Use [TouchScreenButton] for buttons that trigger gameplay movement or actions, as [TouchScreenButton] supports multitouch.
