XXX TO DO:
|
||||
|
||||
- generalize the scrolling listbox with some behavior into a base class
|
||||
- add popup menu with more options (e.g. doc strings, base classes, imports)
|
||||
- show function argument list (have to do pattern matching on source)
|
||||
- should the classes and methods lists also be in the module's menu bar?
