QComboBox + QAbstractModel findText problem?
Message 1 in thread
To answer my own question: I found the problem. I copied the
data() example from the model/view docs for my model, which contains the
following code snippet:
if (role == Qt::DisplayRole)
return stringList.at(index.row());
A model like this is not 100% compatible with a QComboBox. To get the
findText() method working, the string must also be returned for the
Qt::EditRole, i.e. the snippet must look like this:
if (role == Qt::DisplayRole || role == Qt::EditRole)
return stringList.at(index.row());

P.S. should stop using the 'reply' button to post here. Not nice for
threading. Wonder why nobody yelled at me, yet. :-)
