Member Function Documentation

virtual void casa::WCInvisTool::get	(	Double &	x,
		Double &	y
	)			const [virtual]

Retrieve the position in linear WorldCanvas coordinates.

virtual void casa::WCInvisTool::getFractional	(	Double &	x,
		Double &	y
	)			const [virtual]

Retrieve the position in fractional linear WorldCanvas coordinates.

virtual void casa::WCInvisTool::keyPressed

(

const WCPositionEvent &

)

[virtual]

Functions called by the local event handling operators - these handle the drawing of the rectangle.

In special conditions, namely double clicking the key, they will pass control on to the doubleInside and doubleOutside functions

Reimplemented from casa::WCTool.

virtual void casa::WCInvisTool::keyReleased

(

const WCPositionEvent &

)

[virtual]

Reimplemented from casa::WCTool.

virtual void casa::WCInvisTool::moved	(	const WCMotionEvent &	,
		const viewer::region::region_list_type &
	)			[virtual]

Reimplemented from casa::WCTool.

virtual void casa::WCInvisTool::positionReady

(

)

[inline, virtual]

Function called when a position is ready.
