[Qt-interest] Force file extension with QFileDialog::getSaveFileName?

[Eric Clark]

If you create your own dialog, you can use QFileDialog::setDefaultSuffix. But if you use the static functions, you will need to implement the logic on your own. It should be fairly easy to do though:

QString fileName = QFileDialog::getSaveFileName(...);
QFileInfo file(filename);
if(file.suffix().isEmpty()) fileName += ".txt";

The above code is an example of the logic to add the default extension ".txt".
