Detailed Description

This class implements additional QCanvasView functionality.

Attention:

This class knows about QCanvasItem objects. Any methods that need to know about classes derived from QCanvasItem that are not part of Qt should be implemented in a derived class.

The original source code was taken from $QTDIR/examples/canvas/canvas.h of version 3.0 of Qt.

Requests:

Move any attached text displays along with moved plotter display.

Requests:

For plots using pixmap, do not draw plot when resizing until mouse is release.

Todo:

Need ability to group and un-group items.

Todo:

add page by adding another standard size page (either A4 or US Letter depending on preferences set somewhere.
