Etymology

MWCRTRegion stands for MultiWorldCanvas Rectangle Tool Region

Synopsis

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

Example

Motivation

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

Constructor & Destructor Documentation

casa::MWCRTRegion::MWCRTRegion ( Display::KeySym keysym = Display::K_Pointer_Button2 )

Constructor.

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

Destructor.

Member Function Documentation

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

Handle double-click inside the rectangle.

Invokes regionReady().

Reimplemented from casa::MWCRectTool.

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

get the linear coords of the current rectangular region

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

get the world coords of the current rectangular region

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

handle events, via new-style interface.

Currently just for reset event.

Reimplemented from casa::DisplayEH.

virtual void casa::MWCRTRegion::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::QtOldRTRegion.
