Etymology

WCRTRegion stands for WorldCanvas Rectangle Tool Region

Synopsis

This class finalises the functionality in WCRectTool 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.

Destructor.

Member Function Documentation

virtual void casa::WCRTRegion::doubleInside ( ) [virtual]

Functions specific to the region drawing - these are called by lower-level event handlers in the base classes.

Reimplemented from casa::WCRectTool.

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

get the linear coords of the current rectangular region

virtual void casa::WCRTRegion::regionReady ( ) [inline, 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
