Also: - Add an option to limit the icon size in PopupMenu. This is similar to how this works in Tree and TreeItem. - Add the same option to TabBar. - Add a theme constant for Tree, PopupMenu, Button, and TabBar to apply this limit on the control level.

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].
|
|
[b]Example of creating a button and assigning an action when pressed by code:[/b]
|
|
[codeblocks]
|
|
[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!")
|
|
[/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]
|
|
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.
|
|
[b]Note:[/b] 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] used when the [Button] is focused. The [code]focus[/code] [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.
