Hi all,
sorry to fill the board again. At the moment I'm trying to
implement a filter for my qtreeview. So far I've managed to implement a
sorter using the QSortFilterProxyModel and I'm able to sort my list by
clicking the headers in my model. However, I've not been successful
connecting my QLineEdit to the filter proxy so I'm wondering if I've missed
a step. This is the code for my GUI. Any assistance is much appreciated.
Thank you
