QFileDialog and file extension

[wysota]

If you can live without using the native file dialog (that's what happens when you use static versions of the dialog), you can create a QFileDialog subclass where you will reimplement accept() to make the checks and modifications yourself "inside" the dialog. If they are successful, call the base class implementation (QDialog::accept() would probably be better than QFileDialog::accept() here). Otherwise don't call the base class accept(), so the dialog doesn't get closed (or something like that). You can also create a helper method that will act in a fashion similar to what QFileDialog's static methods do (like return the list of files).

Hi,

I have same problem. Is this a bug for Qt's file dialog?
Qt must check and insert extension automatically.

Why would Qt insert the extension automatically (especially when you are using a native dialog)?

QString path = QFileDialog::getSaveFileName(...);
if(path.isEmpty()) return;
if(!path.endsWith(".ext"))
  path.append(".ext");

QString path = QFileDialog::getSaveFileName(...);
if(path.isEmpty()) return;
if(!path.endsWith(".ext"))
  path.append(".ext");
