Detailed Description

Base implementation of WCTool for invisible (non-drawing) tools.

Synopsis

This class implements some of WCTool, and adds additional interface to support invisible (ie. non-drawing) tools for WorldCanvases.

Member Function Documentation

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

virtual

Retrieve the position in linear WorldCanvas coordinates.

virtual void casa::WCInvisTool::getFractional	(	casacore::Double &	x,
		casacore::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

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 ( )

inlinevirtual

casacore::Function called when a position is ready
