[Qt-interest] Help Tree view with Dir Model

[yogesh upreti]

Hi Denis,
QFileSystemModel is working in background and loading step by step in
parallel, this is a little bit undesirable.
I read this mail before and the document too but I still can't find how to
specify which should be the selected index??

Thanks anyway for help


Hi,
Qt Doc recommends use QFileSystemModel instead of QDirModel. The similar
topic discussed in this list:
http://lists.trolltech.com/pipermail/qt-interest/2010-March/021062.html
and
http://lists.trolltech.com/pipermail/qt-interest/2010-March/021195.html

Hope it helps.
