[Jabref-users] Patch for group selection tree - ID: 2211981

[Martin R. <Mar...@fu...>]

Hello *,

We implemented feature "group selection tree - ID: 2211981" and uploaded 
it at the JabRef patchtracker. The feature demands to store the 
treestructure and the groupselection while switching between several 
tabs, so that they can be restored when you return to the according tab.

We store the selection in an array and the treestructure in an 
enumerator. The storing happens when you switches the tab. If you return 
to the according tab groupselection and treestructure are restored. We 
also restore the scrolled area, so that really everything stays the same 
in the grouppanel. There is a setting in the prefernces where you can 
choose if you want to initially expand all subgroups. If you enable this 
setting all subgroups are expanded if you switch the tab. We left this 
prefernce unchanged.

We didn't add any JUnit test because testing seemed not practicable.

We apreciate comments and ideas!
