Detailed Description

This class implements additional FigureEditor functionality particular to QtView objects.

Attention:: Methods that only need to know about QCanvasItem objects should be implemented in the base class.

Requests:: Coordinates should show when mouse is over plot.

Should be no need for right mouse down.

Requests:: Need remove empty pages menu item.

Bug:: @@ When adding new plot, not all of the new plot becomes visible.

Bug:: @@ When pasting from pasteboard, views are not displayed when pasted on top of existing view.

Bug:: Canvas size doesn't automatically enlarge when size of a view is dragged to be larger than canvas.

Todo:: Should implemented method hasSelectedViews() since in a number of places the implementation calls selectedViews only to ask if vector is empty.
