slot

Deletes the current transfer texture.

void OpenGLColorgradientWidget::resizeGL	(	int	width,
		int	height
	)

protected

Sets the new viewport and calculates the vertices from the quad.

Parameters:

width	The new width of the window, measured in pixel.
height	The new height of the window, measured in pixel.
