Standard themed Button.
</brief_description>
<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.

<member name="alignment" type="int" setter="set_text_alignment" getter="get_text_alignment" enum="HorizontalAlignment" default="1">

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.
