Welcome to LQ!!

Please tell us a bit more about the project. eg: Where will the program find the images? Will there be user interaction to stop, restart, rewind, fast forward, etc.?

Does the "designer toolkit" go beyond the basic capabilities of QT?

I wanna write a code in c++ (in QT)for making a slideshow of images. It should be like MS powerpoint without any controls like rewind, fastforwd, stop and play !!!
It should read image files by taking the target of the file from the user and display them as a slideshow.

You can do simple slide shows using an image manager such as Digikam. And I ma pretty sure that OpenOffice Impress also does slide shows.

What is the reason for writing the program? eg what features do you need that don't already exist other programs?

Are you proficient in C++ and QT?

Finally, to get better help, post some of the work you have done so far.

Thats the whole point where i am facing a problem !!!

I am not supposed to use any pre-existing softwares but I need to code them .!!!
Ya I am proficient in c++ and trying to explore QT !!
so need help for that...

Are there any header files or existing in built functions in c++ for displaying images !!

Homework, as I suspected.....

I think the answer will be found in the QT documentation. C++ only provides the basic language environment. QT (or GTK) is what gives you the specific graphical tools, the interface into X, etc.

Here is the last help that I personally can offer:

This was found by entering "qt display images" in Google.

Good luck
