Is there a way to use the QFileDialog to create a custom file dialog? I need to be able to put a "file information" section on the right hand side of the window...

Thanks

Can you use a layout to define the Widget that gets set into the preview? For instance, I am creating a QVBoxLayout object and populating it with various things, including a push button. So far I cant get anything to display in the preview, and I cannot define a signal/slot for the button.

If you can do these things, then this is what I was looking for. Else, I will need to define my own open dialog...

Answer...

I finally figured out to use the addWidgets() function of QFileDialog to add a 2 labels and a button to the bottom of the open file dialog. I first had to inherit from QFileDialog in my class, then called the addWidgets in the constructor. Not exactly what I had in mind, but it works.

What exactly did you have in mind?

I originally wanted the labels on the right hand side of the QOpenFileDialog instead of the bottom. But inheriting only allows for a single label to be placed on the right or left hand side of the dialog.

RE: Answer...

As any_skoa mentioned in a previous email, you can easily do what you want with setInfoPreview() or setContentsPreview().

It is true that it allows for a single widget. However, you can have as many labels, buttons or whatever you like within this widget. Use a QVBox for example and put your labels into it.

No problem at all.

I implemented the SetInfoPreview that was been mentioned. However, when I click on a new file, the preview information does not redraw? is there something that I am missing? This is not the end result, but just a check to see if it works...

Source code

class FilePreview : public QVBox, public QFilePreview
{
public:
   FilePreview( QWidget *parent = 0 ) : QVBox( parent ) {}

   void previewUrl( const QUrl &u )
   {
      QLabel *fileTypeLbl;

      QString path = u.path();
      
      setCaption( "File Information:" );

      new QLabel( tr( "File Type:" ), this );
      fileTypeLbl = new QLabel( path, this );
   }
};

previewUrl() should be called whenever a new file is selected.

Your current implementation will result in very strange behaviour! You should create your widgets in the constructor of your class, not the previewUrl() method.

The "strange behavior" is that a new QVBox get placed alongside the existing one, but nothing gets redrawn until you deselect the preview box, then reselect again, then there is the updated information under the previous information.

Thanks for the help chickenblood!!
