    Question Question about thumbnailing different kinds of images

    Hi all, I'm creating an application and I need to do a thumbnailing of the images in a selected directory from a tree widget with all the directories that the user can view. These images have different formats and I need to thumbnail the images of each format in a separate window. In most of the cases the images are very large (in order of 3000x3000 pixels). I've thought to use a QTabWidget with a QListWidget in each tab window for each format. Then, I start a thread that creates the thumnailed images and send them to the main thread to put them on the correct tab. Well, here's my question: anybody could suggest me what's the best way to fill each list widgets with the thumbnailed images. There are various solutions: starting a thread at the same time for each tab window (format) in the tab widget (could need a lot of cpu and memory but also could be that some formats have no images an others like the jpeg tab have most of the images) , starting a thread that fills only the tab that the user is viewing, ... Any ideas?

    Thanks
