Although I haven't been able to check it out today, I'm pretty sure that
there is a document in the developer support area at www.geoworks.com that
does a very good job of showing how to use multiple source files.
>>>>I learned that it is (almost?) impossible to separate UI-objects into
different goc files.<<<
Correct for all your static UI objects. The only objects that can live
outside your main UI source file are objects which are added dynamically by
your app.
As Gerd said, always do an mkmf and pmake depend whan you add a new source
file.
Hope this helps...
