|
[OptionButton] is a type of button that brings up a dropdown with selectable items when pressed. The item selected becomes the "current" item and is displayed as the button text.
|
|
See also [BaseButton] which contains common properties and methods associated with this node.
|
|
[b]Note:[/b] The IDs used for items are limited to signed 32-bit integers, not the full 64 bits of [int]. These have a range of [code]-2^31[/code] to [code]2^31 - 1[/code], that is, [code]-2147483648[/code] to [code]2147483647[/code].
|
|
[b]Note:[/b] The [member Button.text] and [member Button.icon] properties are set automatically based on the selected item. They shouldn't be changed manually.
