My guess is that there's nothing to select, because you are loading
images in a second thread, and at the time setSelectionIndexes is
called, the thread hasn't managed to load even the first image yet.
You'll need to arrange for the thread to tell the main thread when it
has done some work so that the first thread can perform the selection.
