Button

Inherits: BaseButton < Control < CanvasItem < Node < Object

Inherited By: CheckBox, CheckButton, ColorPickerButton, MenuButton, OptionButton

A themed button that can contain text and an icon.

Description

Button is the standard themed button. It can contain text and an icon, and it will display them according to the current Theme.

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

GDScriptC#

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!")

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 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.

int align_to_largest_stylebox = 0 🔗

This constant acts as a boolean. If true, the minimum size of the button and text/icon alignment is always based on the largest stylebox margins, otherwise it’s based on the current button state stylebox margins.

int h_separation = 4 🔗

The horizontal space between Button‘s icon and text. Negative values will be treated as 0 when used.

int icon_max_width = 0 🔗

The maximum allowed width of the Button‘s icon. This limit is applied on top of the default size of the icon, or its expanded size if expand_icon is true. The height is adjusted according to the icon’s ratio. If the button has additional icons (e.g. CheckBox), they will also be limited.

int outline_size = 0 🔗

The size of the text outline.

Note: If using a font with FontFile.multichannel_signed_distance_field enabled, its FontFile.msdf_pixel_range must be set to at least twice the value of outline_size for outline rendering to look correct. Otherwise, the outline may appear to be cut off earlier than intended.

Font font 🔗

Font of the Button‘s text.

int font_size 🔗

Font size of the Button‘s text.

Texture2D icon 🔗

Default icon for the Button. Appears only if icon is not assigned.

StyleBox disabled 🔗

StyleBox disabled_mirrored 🔗

StyleBox used when the Button is disabled (for right-to-left layouts).

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 hover 🔗

StyleBox used when the Button is being hovered.

StyleBox hover_mirrored 🔗

StyleBox used when the Button is being hovered (for right-to-left layouts).

StyleBox hover_pressed 🔗
