00009  Purpose : a view is a part of the graphical representation which is
00010            contained in an independent QFrame. There are two ways in which this
00011      class can be used: 
00012      1. pure Qt-Views (contains only Qt-Widgets) useful if complicated
00013         graphics are not needed
00014      2. pure SViewEl-Containers ... mouse and paint-events are delegated
00015         to the dependent ViewEl(s). The view is responsible for
00016         setting up the graphical context, placing the view elements
00017         in a reasonable way and for interacting with the window
00018         system (event handling). CAUTION: Views must register themselves
00019         at the dependent ViewEl(s).
