Detailed Description

The class of derived from ViewBase for drawing as a Qt Widget.

It is derived from QWidget in order to get a position and size in its parent. It also derives from QtViewImp where most of the drawing code is implemented.

Bug:: @@@ Displaying an empty NTuple leads to Qfont error messages.

See jira bug report.
