[Button] is the standard themed button. It can contain text and an icon, and it will display them according to the current [Theme].
|
|
[b]Example:[/b] Create a button and connect a method that will be called when the button is pressed:
|
|
[codeblocks]
|
|
[gdscript]
|
|
func _ready():
|
|
var button = Button.new()
|
|
button.text = "Click me"
|
|
button.pressed.connect(_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.Pressed += ButtonPressed;
|
|
AddChild(button);
|
|
}
|
|
|
|
private void ButtonPressed()
|
|
{
|
|
GD.Print("Hello world!");
|
|
}
|
|
[/csharp]
|
|
[/codeblocks]
|
|
See also [BaseButton] which contains common properties and methods associated with this node.
|
|
[b]Note:[/b] Buttons do not detect 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.

|
|
[StyleBox] used when the [Button] is focused. The [theme_item focus] [StyleBox] is displayed [i]over[/i] 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.
