Standard themed Button.

Description
-----------

Button is the standard themed button. It can contain text and an icon, and will display them according to the current :ref:`Theme<class_Theme>`.

**Example of creating a button and assigning an action when pressed by code:**

::

    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!")

Buttons (like all Control nodes) can also be created in the editor, but some situations may require creating them from code.

See also :ref:`BaseButton<class_BaseButton>` which contains common properties and methods associated with this node.

**Note:** 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 :ref:`TouchScreenButton<class_TouchScreenButton>` for buttons that trigger gameplay movement or actions, as :ref:`TouchScreenButton<class_TouchScreenButton>` supports multitouch.
