Etymology

"RectRegionEvent" holds information about a rectangular 'region' selected by the user with the MWCRTRegion mouse tool. NB: glish uses the term 'pseudoregion' instead to refer areas selected by MWCRTRegion et. al. In the context of Image Analysis, 'Region' refers to a more complex object, which may be assembled from multiple pseudoregions.

Synopsis

RectRegionEvent is created by the MWCRTRegion display library mouse tool, when a rectangular area is selected by it on a WorldCanvas where the tool is active. The event is passed (via WorldCanvas::sendEvent()) to the generic DisplayEH s registered with that WorldCanvas.

Motivation

A mechanism was needed to notify library objects associated with a WorldCanvas (in particular, DisplayData s) when a rectangular region was selected on the WC via MWCRTRegion. Formerly, this information was sent only to glish. This event is on a different level from the mouse/keyboard WorldCanvasEvents and serves a different purpose, so a new event type was created.
