[Qt-interest] 'Back' button not working properly.

[Saravana Selvaraj]

Hi Ravi,

    {
     >> Mediagallery();
    }

Here, the above statement creates a new object of type Mediagallery. It
doesn't call its own class constructor. 

So, in your case, you need to move the required functionality from
constructor to some other member function and call this new member
function from back2gallery().

Hope this helps.

Regards,
Saravana

Hi everyone,
    I am having problems implementing the functionality of a 'Back'
button.I am working on a Media gallery using Qt 4.4.3. When  the gallery
is opened,we see the first 10 pictures present in it(The 10
pictures/thumbnails are set on 10 QPushButtons).On clicking any of the
10 pics ,it gets enlarged (set on top of a QLabel). Now, once the
enlarged picture  is shown,I am thinking of giving a 'Back'button  so
that the user can go back to the initial view showing the 10 thumbnails
on the 10 pushbuttons. I created a button 'back' and connected it to a
slot 'back2gallery()' inside which I called the constructor again. My
constructor's name is 'Mediagallery()'.So, I wrote- void
Mediagallery::back2gallery()
    {
      Mediagallery();
    }

But,it's not working.I was thinking that it was simple...but,guess I did
it wrong. Please advice on how to get past this issue. Thank you. Ravi
