Member Function Documentation

virtual void casa::MultiPolylineToolImpl::doubleInside ( )

protectedvirtual

Handle double-click inside the polygon.

Invokes regionReady().

Reimplemented from casa::MultiPolylineTool.

void casa::MultiPolylineToolImpl::getLinearCoords	(	casacore::Vector< casacore::Double > &	x,
		casacore::Vector< casacore::Double > &	y
	)

protected

get the linear coords of the current ploygon region

void casa::MultiPolylineToolImpl::getWorldCoords	(	casacore::Vector< casacore::Double > &	x,
		casacore::Vector< casacore::Double > &	y
	)

protected

get the world coords of the current polygon region

virtual void casa::MultiPolylineToolImpl::regionReady ( )

inlineprotectedvirtual

This function is called when a region is deliberately "finished" by the user.

It can be implemented to do further actions, such as report the region to the application.

Reimplemented in casa::QtPolylineToolRegion.
