194749 - Tree widget doesn't work on Qt

Status: RESOLVED WONTFIX

(Core Graveyard :: Ports: Qt, defect)

Description

[Robert Kaiser]

The <tree> widgets in XUL UI are not really functional in Qt port. If you open
e.g. bookmarks window or sidebar, and want to expand/collapse a bookmarks
folder, it doesn't react in any way, not even if you "force" a repaint by
switching desktops. Ah, well, single click seemingly doesn't work, but I saw now
that double click on tree item does something... It actually performs the
double-click on an item thre lines or so above the one that I really did click
upon. Hmm, OK, single click does work in a way that it seems to also fire on the
item around three items above the one I clicked upon, it seems to respect the
horizontal position though (seen in manage bookmarks at least, it seems
bookmarks sidebar always does expand/collaps on a single click anywhere on the
item).

Hmm, I hope I've given you a clue...

I've seen the problem. Is such a tree somewhere else as in the Properties? Will
take the bug, may be a positioning problem. Does it works with key handling?

It's much better after applying the fix of bug 197737, though there seems some
issues left. I can't investigate all though because of our bad paint problems
currently.

Those are a few lines I get when opening the bookmarks manager and playing
around a bit, then closing again:

This bug has been buried in the graveyard and has not been updated in over 5 years. It is probably safe to assume that it will never be fixed, so resolving as WONTFIX.
