Regions are used by handler objects to denote the handler should only respond when an event object occurred in some sub-area of a graphical. As handler objects have become old-fashioned since the introduction of class gesture this class too is seldomly used. For example, the region region(x, y, w/10, h/10) Denotes a region with the same origin as the area it is related to, extending to 10% in both directions.CchainsizeOI xIeN$class/expression$C.expressioneN$class/area$C.areaEN$class/handler$C.handlerXnnnsNM.region.G.area_heightCman_method_card identifiermodule last_modifiednamesummary descriptionsee_alsoinherit diagnosticsdefaultsbugsOI xNM.region.G.area_heightRIOI x,{PÒN area_heightnOI x¦Dimension of the described region for the specified area.
