inlineoverridevirtual

Update size and resize step of a widget in the window.

After retrieval of the minimal size and the resize-steps of a widget, this function is called to allow further refinement, typically by computing the real maximal size of the content. Afterwards, size is taken to be the minimal size of the widget and resize is taken to contain the resize steps. For the convenience of the callee, padding contains the amount of padding between the content and the edge of the widget. This should be added to the returned size.

Parameters

	widget	Widget number.
[in,out]	size	Size of the widget.
	padding	Recommended amount of space between the widget content and the widget edge.
[in,out]	fill	Fill step of the widget.
[in,out]	resize	Resize step of the widget.
