Button¶
Inherits: BaseButton < Control < CanvasItem < Node < Object
Inherited By: CheckBox, CheckButton, ColorPickerButton, MenuButton, OptionButton
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 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!")
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!");
}
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.
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 TouchScreenButton for buttons that trigger gameplay movement or actions, as TouchScreenButton supports multitouch.

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

StyleBox used when the Button is being hovered.
StyleBox normal
Default StyleBox for the Button.
StyleBox pressed
StyleBox used when the Button is being pressed.
