Detailed Description

template<typename BOOL>
class gobjSwitch< BOOL >

If the switch is on draw the object else don't.

This class wraps a gobj in a switch so that the gobj can be displayed or not displayed depending on isdrawn's state.

The BOOL is designed to have either bool or bool & .

template<typename BOOL>

gobjSwitch< BOOL >::gobjSwitch	(	gobj *	x_,
		BOOL	isdrawn_,
		boolc	cleanup_ = true
	)			[inline]

Pass the object, set the initial drawing state and memory policy.

If x_ is 0 this switch is in a unconstructed state.
