casa::PCInvisTool::PCInvisTool	(	PixelCanvas *	pcanvas,
		Display::KeySym	keysym = `Display::K_Pointer_Button1`
	)

Constructor.

Requires a PixelCanvas to operate on, and a key to catch.

virtual casa::PCInvisTool::~PCInvisTool ( ) [virtual]

Destructor.

virtual void casa::PCInvisTool::get	(	Int &	x,
		Int &	y
	)		const `[virtual]`

Retrieve the position in PixelCanvas pixel coordinates.

virtual void casa::PCInvisTool::getFractional	(	Float &	x,
		Float &	y
	)		const `[virtual]`

Retrieve the position in fractional PixelCanvas coordinates.

virtual void casa::PCInvisTool::keyPressed ( const PCPositionEvent & ev ) [virtual]

Functions called by the local event handling operators.
