	<methods>
		<method name="_get_allowed_size_flags_horizontal" qualifiers="virtual const">
			<return type="PackedInt32Array" />
			<description>
				Implement to return a list of allowed horizontal [enum Control.SizeFlags] for child nodes. This doesn't technically prevent the usages of any other size flags, if your implementation requires that. This only limits the options available to the user in the Inspector dock.
				[b]Note:[/b] Having no size flags is equal to having [constant Control.SIZE_SHRINK_BEGIN]. As such, this value is always implicitly allowed.

		<method name="fit_child_in_rect">
			<return type="void" />
			<param index="0" name="child" type="Control" />
			<param index="1" name="rect" type="Rect2" />
			<description>
				Fit a child control in a given rect. This is mainly a helper for creating custom container classes.

		<method name="queue_sort">
			<return type="void" />
			<description>
				Queue resort of the contained children. This is called automatically anyway, but can be called upon request.
