Etymology

MultiPointToolImpl stands for MultiWorldCanvas Point Tool Region

Synopsis

Why this "finalization" is required is beyond me... i.e. why not roll this functionality into the parent class??

Thu Aug 18 20:13:53 UTC 2011

This class finalises the functionality in MWCPointTool to implement event-based drawing of elliptical regions on a WorldCanvas. Double clicking inside the constructed point emits the region, whilst pressing Escape cancels the region.

Example

Motivation

Elliptical regions are the most common regions, and constructing them visually can be very efficient.

To Do

casa::MultiPointToolImpl::MultiPointToolImpl	(	viewer::RegionSourceFactory *	rf,
		PanelDisplay *	pd,
		Display::KeySym	keysym = `Display::K_Pointer_Button2`
	)

Constructor.

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

Destructor.

Member Function Documentation

virtual void casa::MultiPointToolImpl::doubleInside ( ) [protected, virtual]

Handle double-click inside the point.

Invokes regionReady().

Reimplemented from casa::MultiRectTool.

void casa::MultiPointToolImpl::getLinearCoords	(	Vector< Double > &	blc,
		Vector< Double > &	trc
	)		`[protected]`

get the linear coords of the current elliptical region

void casa::MultiPointToolImpl::getWorldCoords	(	Vector< Double > &	blc,
		Vector< Double > &	trc
	)		`[protected]`

get the world coords of the current elliptical region

virtual void casa::MultiPointToolImpl::handleEvent ( DisplayEvent & ev ) [virtual]

handle events, via new-style interface.

Currently just for reset event.

Reimplemented from casa::DisplayEH.

virtual void casa::MultiPointToolImpl::regionReady ( ) [inline, protected, virtual]

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::QtPointRegion.
