How do I make my own QDialog working like for example QFileDialog

[Randulf]

Thanks a lot for the help and tips!!
Got it working now.
Removed exec(), accept(), reject() and done().

Now I can just

int r = myDialog->exec()
if(r==1)
    QStringList settings = myDialog->readSettings()
delete myDialog

int r = myDialog->exec()
if(r==1)
    QStringList settings = myDialog->readSettings()
delete myDialog

To copy to clipboard, switch view to plain text mode 

Thanks again!!!
