Synchronize a list and a viewer

**MTK358** · 27th September 2010, 22:33

I have a QStandardItemModel full of filenames, and a file viewer widget. How do I synchronize the currently viewed file with the list's current item?

With signal and slots.

I tried doing it with the currentChanged() signal, but it's not emitted when the list is cleared or when it's not in focus.

I am asking because I once used QTreeWidget and it's signal

Qt Code:

Switch view

itemSelectionChanged()

itemSelectionChanged()

To copy to clipboard, switch view to plain text mode

and I had no problems both when selection was changed with mouse or key... though I can't really check if it would work in your case

nevertheless You can try it out

Items will be added, removed, and cleared without the list being in focus.

to be honest I can not say a word about removing or clearing the list of items because I had to abandon writing it due to other more important project I am working on right now

If I find some time, I will go for it to check it out
