draw the distance vector on a PixelCanvas.

(To be called only by the base class refresh event handler).

Reimplemented from casa::MultiWCTool.

Reimplemented from casa::MultiWCTool.

virtual void casa::MWCPositionVelocityTool::reset ( casacore::Bool skipRefresh = false )

virtual

Reset to non-showing, non-active.

Refreshes if necessary to erase (unless skipRefresh==true). (Does not unregister from WCs or disable future event handling).

Reimplemented from casa::MultiWCTool.
