Hello!
Would you please tell me how to append filter text to filename as extension?

Found this solution:
http://www.qtcentre.org/forum/f-qt-p...ht=QFileDialog

but maybe there is a lighter one for such simple (I hope) operation?

Qt Code: 
  1. void snapShot::on_actionSave_as_activated()
  2. {
  3. 	if ( preview->palette().brush ( backgroundRole() ).texture().isNull() )
  4. 	{
  5. 		QMessageBox::critical ( this,tr ( "Error" ),tr ( "Nothing to save" ),QMessageBox::Ok,0 );
  6. 		return;
  7. 	}
  8.  
  9. 	QString fName;
  10. 	QString frmts;
  11. 	QFileDialog fd ( this );
  12. 	fd.setAcceptMode ( QFileDialog::AcceptSave );
  13. 	fd.setWindowTitle ( tr ( "Save as..." ) );
  14.  
  15. 	QStringList filters ( fd.nameFilters() );
  16. 	filters << tr ( "PNG Images (*.png)" );
  17. 	filters << tr ( "JPG Images (*.jpg *.jpeg)" );
  18. 	filters << tr ( "XPM Images (*.xpm)" );
  19. 	filters << tr ( "All Images (*.png *.jpg *.jpeg *.xpm)" );
  20. 	fd.setNameFilters ( filters );
  21.  
  22. 	fd.setDirectory ( WorkDir );
  23. 	fd.setFileMode ( QFileDialog::AnyFile );
  24. 	if ( fd.exec() ==QDialog::Accepted )
  25. 	{
  26. 		QStringList files = fd.selectedFiles();
  27. 		if ( !files.isEmpty() )
  28. 			fName = files[0];
  29. 	}
  30. 	if ( fName.length() >0 )
  31. 	{
  32. 		if ( saveInFile ( fName ) ) {
  33.  
  34. 			if( !QFileInfo(fName).exists() )
  35. 				fName.append(".png");
  36. 		    setWindowTitle( QFileInfo(fName).absoluteFilePath() + " - " + initWindowTitle);
  37. 		}
  38. 	}
  39. }
To copy to clipboard, switch view to plain text mode 

When the user print "file.jpg" - it's ok, but when he print just "file" and then choose filter ("jpg") - exec() returns "file" without any information about desired extension...

Thanks in advance!
