Numerical input text field. SpinBox is a numerical input text field. It allows entering integers and floats. [b]Example:[/b] [codeblock] var spin_box = SpinBox.new() add_child(spin_box) var line_edit = spin_box.get_line_edit() line_edit.context_menu_enabled = false spin_box.align = LineEdit.ALIGN_RIGHT [/codeblock] The above code will create a [SpinBox], disable context menu on it and set the text alignment to right. See [Range] class for more options over the [SpinBox]. [b]Note:[/b] [SpinBox] relies on an underlying [LineEdit] node. To theme a [SpinBox]'s background, add theme items for [LineEdit] and customize them. [b]Note:[/b] If you want to implement drag and drop for the underlying [LineEdit], you can use [method Control.set_drag_forwarding] on the node returned by [method get_line_edit]. Applies the current value of this [SpinBox]. Returns the [LineEdit] instance from this [SpinBox]. You can use it to access properties and methods of [LineEdit]. [b]Warning:[/b] This is a required internal node, removing and freeing it may cause a crash. If you wish to hide it or any of its children, use their [member CanvasItem.visible] property. Sets the text alignment of the [SpinBox]. If not [code]0[/code], [code]value[/code] will always be rounded to a multiple of [code]custom_arrow_step[/code] when interacting with the arrow buttons of the [SpinBox]. If [code]true[/code], the [SpinBox] will be editable. Otherwise, it will be read only. Adds the specified [code]prefix[/code] string before the numerical value of the [SpinBox]. Adds the specified [code]suffix[/code] string after the numerical value of the [SpinBox]. Sets a custom [Texture] for up and down arrows of the [SpinBox].
