A themed button that can contain text and an icon.

.. rst-class:: classref-introduction-group

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

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

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


.. tabs::

 .. code-tab:: gdscript

    func _ready():
        var button = Button.new()
        button.text = "Click me"
        button.pressed.connect(self._button_pressed)
        add_child(button)
    
    func _button_pressed():
        print("Hello world!")

 .. code-tab:: csharp

    public override void _Ready()
    {
        var button = new Button();
        button.Text = "Click me";
        button.Pressed += ButtonPressed;
        AddChild(button);
    }
    
    private void ButtonPressed()
    {
        GD.Print("Hello world!");
    }



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.

:ref:`StyleBox<class_StyleBox>` used when the **Button** is focused. The ``focus`` :ref:`StyleBox<class_StyleBox>` is displayed *over* the base :ref:`StyleBox<class_StyleBox>`, so a partially transparent :ref:`StyleBox<class_StyleBox>` should be used to ensure the base :ref:`StyleBox<class_StyleBox>` remains visible. A :ref:`StyleBox<class_StyleBox>` that represents an outline or an underline works well for this purpose. To disable the focus visual effect, assign a :ref:`StyleBoxEmpty<class_StyleBoxEmpty>` resource. Note that disabling the focus visual effect will harm keyboard/controller navigation usability, so this is not recommended for accessibility reasons.
