	<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]
		[codeblocks]
		[gdscript]
		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!")
		[/gdscript]
		[csharp]
		public override void _Ready()
		{
		    var button = new Button();
		    button.Text = "Click me";
		    button.Connect("pressed", this, nameof(ButtonPressed));
		    AddChild(button);
		}

		private void ButtonPressed()
		{
		    GD.Print("Hello world!");
		}
		[/csharp]
		[/codeblocks]
		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.
