If umbrello supports this then how do I use this? I did not find some menu 
item like "Read Class from Header File" (okay - probably something shorter 
than this example :-) ... give me a hint ...

Then lets start gather things which might be useful inside of user 
profile/setting:
- - Qt support (i.e. signals/slots/Q_OBJECT); does this make sense only for C++? 
I did not use any other Qt language binding - thinking of perl and python 
e.g.; how are Q_OBJECT declaration done there?
- - syntax style of generated code

So adding it to the feature list with a low priority is a good idea.

We should keep in mind that generating the model from available sources would 
be a nice feature, too. So maybe another property of code generation whether 
an operation shall be implemented inlined or not. Okay, whether this is 
possible depends on the language.

I understand and agree.

I have asked yesterday whether the parsing 'part's of KDevelop can be easily 
reused by other applications without the need of KDevelop itself. I am going 
to give a summary as soon as I receive some useful information.
