Detailed Description

A concrete window class that contains the canvas and responds to menu item and tool bar events from the window and messages sent by the Inspector.

Attention:

This class should implement those actions specific to HippoDraw as an application. All changes to the CanvasView should be implemented in the that class so that other applications can benefit from the implementation.

Bug:

If a document could not be opened, error messages displays, but one get a new empty canvas window.

It is not throwing an exception which is read to be caught.

Bug:

@ Windows only, not all the canvas is initially shown.

Run displays.py and the CanvasWindow needs manual resizing for all the canvas to be seen.

Bug:

The View/Cut empty pages button doesn't work and is not enabled.

Requests:

@ Be able to retrieve from SIP Python module, information on the active displays such as axis labels, etc.

Requests:

Have a editable NTuple table view.

Requests:

@ Be able to group canvas items together and set parameters to all of them at once.

This makes sense for some Inspector tabbed panes but not for others.

Requests:

@ Open documents read only.

This could be the default when the file Open menu item is used.

Requests:

@ Have CanvasWindow size a setting.

Requests:

A clear all button on the tool bar.

Requests:

A setting on whether to prompt user or not for clear all.

Todo:

@@ Be able to ask canvas if it is saved from Python.

Todo:

Make it a setting if the Inspector window comes up automatically or not.

Todo:

Respond to Page Up and Page Down keys.

Todo:

Needs something to display on the canvas for values only seen in the Inspector.

One example is the name of the ntuple file. This is so that the document when printed can be more useful as a stand alone.
