◆ AssignSizePosition()

void NWidgetHorizontalLTR::AssignSizePosition	(	SizingType	sizing,
		int	x,
		int	y,
		uint	given_width,
		uint	given_height,
		bool	rtl
	)

overridevirtual

Assign size and position to the widget.

Parameters

sizing	Type of resizing to perform.
x	Horizontal offset of the widget relative to the left edge of the window.
y	Vertical offset of the widget relative to the top edge of the window.
given_width	Width allocated to the widget.
given_height	Height allocated to the widget.
rtl	Adapt for right-to-left languages (position contents of horizontal containers backwards).

Afterwards, pos_x and pos_y contain the top-left position of the widget, smallest_x and smallest_y contain the smallest size such that all widgets of the window are consistent, and current_x and current_y contain the current size.

Reimplemented from NWidgetHorizontal.
