| 2 | |
| 3 XXX TO DO: | |
| 4 | |
| 5 - reparse when source changed (maybe just a button would be OK?) | |
| 6 (or recheck on window popup) | |
| 7 - add popup menu with more options (e.g. doc strings, base classes, imports) | |
| 8 - show function argument list? (have to do pattern matching on source) | |
| 9 - should the classes and methods lists also be in the module's menu bar? | |
| 10 - add base classes to class browser tree | |
