After creation of a group, the group should be focused

[koppor]

1. Create a new library
2. Ensure that "Groups" are visible:
   
3. Create new Group "Test": Click on "Add group" (below), enter "Test" as name, click "OK"
   
4. Result: Group "Test" created, group "All entries" focused:
   

Expected result: Group "Test" focused:

This issue is very much about code reading and understanding how JavaFX and JabRef works. The fix itself probably will be three lines of code. The challenge is really: Which three lines and where to put these lines.

I think i know where to add those "three lines", in src/main/java/org/jabref/gui/groups/GroupTreeViewModel.java there is a function addNewGroupToRoot() which is called when a new group is made using the "Add group button" but i cant figure out which function to call inside this function so that the newly added group should be focused. I think its maybe setSelectedGroup() function of StateManager class but i am not able to use it correctly, any help is appreciated.

Building on Divyam's sluthing, I've made a fork and a branch on it that is able to successfully select and focus the new node.

However, I wonder if this actually desirable behavior? In many use cases, I can imagine wanting to select a number of entries, create a new group, and add them to that group. In the current version, this is straightforward: select entries -> Add group -> right click on group -> Add selected entries.

The new behavior, however, means that changing the group will deselect those entries. Now, if a person attempts to select before making the group, their selection will be lost and they'll have to navigate back to the previous page before they can reselect -> right-click on group -> Add selected entries.

I might suggest two options, which sort of go hand-in-hand. One is a new option in the Add group dialogue's Collection options, which would be From selection and include all selected entries. The second would be that right clicking on an entry or a group of selected entries would allow the option to Add group from selection, which would launch the Add group dialogue with the From selection option pre-selected. Both would reduce the length of time it takes to generate a group in this manner, and seem fairly straight forward to implement.

I'll submit a pull request with the current fix, but think it may be wise to implement these sorts of feature additions before it is merged into main. If this seems reasonable, I would be happy to go ahead and work to implement those changes.

can i ask which function did you finally end up using to focus the added group, for my knowledge?

Had to change things in three spots:

1. In GroupTreeViewModel.addNewSubgroup(), add the subgroup to the parent, and use the return value to instantiate a new GroupNodeViewModel that you put into GroupTreeViewModel.selectedGroups.

                GroupTreeNode newSubgroup = parent.addSubgroup(group);
                selectedGroups.setAll(new GroupNodeViewModel(database, stateManager, taskExecutor, newSubgroup, localDragboard, preferences));

2. In GroupTreeView, when registering a bidirectional binding between the treeView's getSelectionModel().getSelectionItems() and the viewModel's getSelectionGroups(), I updated the callback function for changes in the treeView to clear the contents of groupTree.getSelectionModel() before adding new selections to it.

BindingsHelper.bindContentBidirectional(
                        groupTree.getSelectionModel().getSelectedItems(),
                        viewModel.selectedGroupsProperty(),
                        newSelectedGroups -> {
>>>                         groupTree.getSelectionModel().clearSelection();
                            newSelectedGroups.forEach(this::selectNode);
                        },
                        this::updateSelection
                ));

3. In the StateManager, I similarly cleared the contents of StateManager.selectedGroups before adding new items.

Trickiest part was that the state was being stored in three separate places, and I had to figure out how to keep the updates between the three of them accurate.

Both are cool. I think, the first one is even more simpler to implement

Add checkbox - and remember in the preference the state of the checkbox.
