Prajnaranjan Das: Please read the documentation that was pointed out to you. They do explain how to do things the Qt way. There further are lots of boks available (a list is "here":http://developer.qt.nokia.com/wiki/Books_and_Links_for_learning_C_and_advanced_topics).

We are glad to help with specific questions, but we will not write your application for you.

Get the Qt sources, go to directory examples/widgets/imageviewer. I think that's basically what you want.

prajnaranjan.das · wrote on 15 Dec 2010, 04:45

Actually that example is used for viewing in window but here I want to build a mobile application, in which It should automatically search and show the images from my mobile device...But for this I'm not getting any idea ......So for this can you please help me ????

Prajnaranjan Das: If you do not want to program the image viewer yourself you can always go to Ovi store and buy one.

If you want to program the application yourself you can take the image viewer example that was pointed out to you and start from there. You will need to modify it a bit of course, but I am sure you will be able to figure it out with some documentation and books. Again I and most others here are willing to answer specific questions, but we can not do your work for you.

I don't understand if you want buy an app, or if you are a newbie and not know Qt.
User have post a possible solution, example of photo viewer like in Qt for desktop or Qml for mobile, you have to look that and choice the best way.
Before please read some documentation about Qt (maybe "here":http://qt.nokia.com/developer/books/) and C++.

You can use QImage and a QWidget subclass create one. It should be very easy. Override the paintEvent in the QWidget subclass to draw the image. To automatically search for images, you should need to implement a recursive function for scanning the file system and finding image files. You should use QFile and related classes. Hope this helps.
