Changes

(the series of tabs encapsulated in another series of tabs is potentially difficult for a learner to comprehend, but an alternative tree view is thought inappropriate because of the horizontal space consumed, and because use of a module should be constrained to the public API of the module).

Activity canvas GTK+ widget hierarchy:

Activity canvas GTK+ widget hierarchy, assuming two modules open, modules "main" and "test", of which "main" has a file "file.py", and "test" has a file "test.py":

*gtk.Notebook (for viewing and writing code, one page per module)

 

**gtk.Notebook (one page per file in each module)

*gtk.Notebook (tab labels "main", "test", "+")

***GtkSourceView (one for each file in each module)

***notebook page label "setup", a GtkSourceView for "setup.py", hidden if not yet edited by learner,

***notebook page label "+", creates a new file, prompts for file name, defaults to .py,

**notebook page label "test", a gtk.Notebook (tab labels "__doc__", "test.py", "setup.py", "+")

***notebook page label "__doc__", a GtkSourceView in read-only mode, hidden if __doc__ is empty,

***notebook page label "setup", a GtkSourceView for "setup.py", hidden if not yet edited by learner,

 

(if the page "+" technique does not work, then toolbar buttons will be required to create a new module, create a new file in a module, or import an example module).
