Detailed Description

Class to keep track of the painter and the current paint area in a paint session. The paint area y-origin and height are specified in Houdini's UI coordinate space (i.e. bottom-left origin).

void RE_WindowDrawablePaintState::popPaintArea

Pop the current paint area from the stack.

void RE_WindowDrawablePaintState::pushPaintArea	(	int	paint_area_x,
		int	paint_area_y,
		int	paint_area_w,
		int	paint_area_h
	)

Push onto the stack a new paint area. This is needed by UI_Viewport, for example, which paints into an FBO with a different viewport.

void RE_WindowDrawablePaintState::toPainterPosition	(	int &	x,
		int &	y,
		int	w = 0,
		int	h = 0
	)		const

Convert the given x,y position from the Houdini UI coordinate space to Qt's QPainter coordinate space. If x,y is for the (bottom-left) corner of a rectangle, then specify the width and height of the rectangle to convert the x,y position to the Qt (top-left) rectangle.

void RE_WindowDrawablePaintState::toUIPosition	(	int &	x,
		int &	y,
		int	w = 0,
		int	h = 0
	)		const

Convert the given x,y position from the Qt QPainter coordinate space to the Houdini UI coordinate space. If x,y is for the (top-left) corner of a rectangle, then specify the width and height of the rectangle to convert the x,y position to the Houdini UI (bottom-left) rectangle.
