Classes to use for a flexible image selection/tagging widget in Qt

Question

Hello, I'm new with Qt and am looking for advice on how to structure this.

I want a flexible widget that can display a set of images (normally read from a directory but other sources too) and let the user select images with the arrow keys and/or mouse and also apply custom tags.

For example there might be 5 tags defined by the application. A user can press a key to select one, and then a little icon would appear in or near the image preview showing that it was selected for that tag.

Would I need to implement this from scratch via drawing on a QWidget or is there something that would make a sensible base class? Thanks!

Answer 1

I would use a QListView base class, and then subclass QStyledItemDelegate. There is an example here which might help you.
