[Qt-interest] FileDialog in the certain folder

[Ender EREL]

You can connect a slot to the
void directoryEntered ( const QString & directory )
signal of QFileFialog, and check if the directory is allowed. If not, 
you can set the directory to any directory you want by using setDirectory().

This may solve your problem with minimum effort but it may create some 
undesired visual results, overall i think it is worth giving a try 
before looking for other solutions.
