◆ update_drawables()

void CLLayoutRenderer::update_drawables	(	double	lx,
		double	ly,

	)

protected

This method goes through all layout objects and checks them if they are within the current viewport. If they are, they are added to the list of objects that are drawn. An object is within the viewport if it's bounding box or parts of it are within the viewport. For curves, each start, end and base point is checked and if any of those is within the viewport, the curve is added to the list. The viewport is specified by its lower left (lx,ly) and upper right point (rx,ry).
