cv::Mat3b	mat_
	Matrix that contains widget shape.

	pointer to parent window that is containing this widget

Additional Inherited Members
Protected Attributes inherited from z::Widget
float	alpha_ = 1
	alpha value of widget. Widgets can be overlapped. Alpha value will be calculated in such cases.

bool	hidden_ = false
	if hidden, a widget will not show on window, but still can react to event.

bool	activated_ = true
	deactivated widget cannot get focus so that it cannot react to events.

bool	focus_ = false

int	zIndex_ = 0
	higher zIndex widget will be in front of lower zIndex widget.
