Hi, I have a tree data structure which I'm trying to display on a QTreeView, using a QSortFilterProxyModel with a QAbstractItemModel as its source. The problem is when I try to add/insert data into my data structure my application crashes without any exceptions or warning messages. It simply dies silently.
I published two source codes pretty much similar to each other on pastebin: - http://pastebin.com/xMjukTcK - The version of the code using the QTreeView connected directly to the QAbstractItemModel, without the proxy. There the insert rows works fine, when I click the "Go" button. - http://pastebin.com/8trLpxLF - The version of the code using the QTreeView connected to the QSortFilterProxyModel. There the insert rows causes the application to crash silently, when clicking the "Go" button. I tried a few different approaches, but got the result over and over again, then I decided to try some help in here to see if someone could please shed a light. Extra useful information about my current environment: * Ubuntu Linux 11.10 * Python 2.7.2 * PyQt version 4.8.6 * Qt version 4.7.4 Many thanks, Gabriel Gabriel de Carvalho Nogueira Reis Software Developer +44 7907 823942
