With 4.3.4 it pick the Qt file dialog. I fully encourage you to upgrade your 
Qt to at least 4.4 because in this version the QFileDialog received a brand 
new data model that is easier to use and much more efficient.

And the solution to solve your problem is to install a QSortFilterProxyModel 
on the QFileDialog (call model() to get the source model). You can then filter 
in the proxy all nodes (directories) you don't want. You can check the doc of 
QSortFilterProxyModel and you can set it on the dialog by calling 
setProxyModel. I fixed some bugs with that particular use case, therefor i 
encourage you to upgrade to 4.5.0 or 4.5.1 when it will be release.
