Change sorting behavior of Quick Outline [message #892295]

Hi there!

I just updated to Xtext 2.3 and discovered the following(don't know if it was like that before):

The outline of my DSL has a different sorting order in outline and quick outline.

I'm using a custom TreeProvider (by extending DefaultOutlineTreeProvider), generating a list of all functions within a document in the order of appearence.
In the outline, the functions are represented correctly, in the quick outline they are ordered alphabetically.
(see attached screenshot)

So after some debugging I found out that there are the classes OutlineFilterAndSorter and QuickOutlineFilterAndSorter where the second one by default always returns true in isSortingEnabled().
Is there a reason for that?

I didn't find a corresponding bind... method in the UIModule to overwrite QuickOutlineFilterAndSorter, so is there way to change this behaviour without overwriting a lot of other classes?

Thanks for your help!

Timo,

just add a binding on your own:

public Class<? extends QuickOutlineFilterAndSorter>
bindQuickOutlineFilterAndSorter() {
return MyQuickOutlineFilterAndSorter.class;
}

The framework will consider that one, too.

Regards,
Sebastian

Hi Sebastian,

Perfect, didn't know that I can add bindings myself.
Thanks!
