Problem with QCompleter
Message 1 in thread
Hi list,
i have a problem using QCompleter in my subclass of QTextEdit. In the
following code cout prints what is expected, but i don't see any popup
appear.
if (completionPrefix != _completer->completionPrefix()) {
_completer->setCompletionPrefix(completionPrefix);
_completer->popup()->setCurrentIndex(_completer->completionModel()->index(0,
0));
cout << "KeyPressEvent: " <<
_completer->completionModel()->index(0,
0).data().toString().toStdString() << endl;
}
QRect cr = cursorRect();
cr.setWidth(_completer->popup()->sizeHintForColumn(0)
+
_completer->popup()->verticalScrollBar()->sizeHint().width());
QCompleter::completionMode is set to popup of course.
Is there something i am missing?
Thanks!

Yes, you doesn't popup...
Have a look at: http://doc.trolltech.com/4.2/tools-customcompleter.html
