Some question as i am begginer in Qt and want to do a lot !
-
- how launch Examples and Demos Launcher !
i read this page http://doc.trolltech.com/4.7/qtdemo.html and it was not there as it said !
2.i am beginner in Qt but really OK in C++ language (for 3 years), i want to make a CBIR app, which load images from local disk and sort them by visual similarity, i heard Qt has variety in user interface design and that's why i chose it. but i don't know to start from where in Qt?! do i need to make Qt C++ app or Qt quick app !?
- i already start and make user interface which has QTreeView in left and QGraphicsView in right side i want to by clicking on local disk directory load images into the right side, but i don't know what library or widget i have to use !
Thanks in Advance.

[/quote]Reinstall Qt. Go to http://qt.nokia.com/downloads and download the SDK or the library version, do a full install. It's got to be there! If you compile Qt from scratch, make sure you compile the examples.

For your Tree You want to create a QFileSystemModel http://doc.qt.nokia.com/latest/qfilesystemmodel.html and then set the QTreeView's Model to this that should make most of the file directory stuff pretty simple.
A C++ app will probably be simpler if you are making a desktop app where as the Qt Quick app would allow you to possibly do some fancier things with animation and so forth if you wanted to head down that track. -
