QCompleter and QAbstractItemModel
Message 1 in thread
Hi there,
I'd like to use Qt 4.2's Completer+QLineEdit to replace one of my older homegrown widgets. The underlaying data is well representable in a Tree, so I derieved a class from QAbstractItemModel and provided it to the Completer via setModel.
The problem is: it doesn't work.
The Model methods do not even get called. ( rowCount and columnCount directly when executing setModel, but that was it ).
I tried it with other AbstractItemModel-Derieved classes in the Application, that work fine in QTreeViews - not working either.
QCompleter and QDirModel work fine though....
Any Ideas?

Did you subclass QCompleter and implement the two virtual functions to work
with your model?

*sigh*
sometimes you just fail to see the forest, because the trees are in your
way...
I declared the completer on the Stack, and it went out of scope before
anything interesting could happen... :)
Thanks anyway...
