Sync position of adw::TabPages in adw::TabView and FactoryVecDeque

[zefr0x]

If I have both adw::TabView and adw::TabBar, when I change the position of a tab from the TabBar, it's position will be changed in the TabView, but not in the FactoryVecDeque, so I lose track of TabPages.

I think that FactoryView::factory_update_position should be implemented for adw::TabView. Way isn't it implemented? Is there any problem?

I tried to use TabView::connect_page_reordered to change the position in the FactoryVecDeque but I wasn't able to. I didn't find a way to reorder elements in FactoryVecDeque when I just have the a TabPage and it's new position.

Is there any thing that I can do?

Currently, only the position of the element in the factory container is synced with the position of the widgets and not the other way around. FactoryView::factory_update_position is only for widgets, so it would not fix your problem and I don't think there's any benefit of implementing it as there is no Position type you could choose for ordering tab pages.

I think I tried to get bidirectional sync working, but I'm not sure why exactly I didn't implement it. I could have another look at the problem, but this might take some time.
