1724841 - (tb-deforestation) [meta] Replace the XUL trees in Thunderbird with something better

Status: NEW

(Thunderbird :: General, task)

Description

[Geoff Lankow (:darktrojan)]

Sooner or later, we'll want to be rid of XUL trees, either because they're being removed from the code, or because we're getting rid of XUL altogether. We have quite a few of them, some of which are tables like the thread pane, most of which are more like simple lists.

This is a meta bug for their removal. We're not in any rush, so I won't be filing lots of bugs to do all the work now, but it will be handy to tie the work together for reference.

I posted on TB discussion forum, but also adding a link here for a possible replacement candidate: https://thunderbird.topicbox.com/groups/developers/Tc68d151e839d9e99/html-tree-replacement-for-the-xul-tree

We have a replacement.

Comment 3

[Ben Bucksch (:BenB)]

We do? Go tell, please! That would be fantastic, assuming it works as well and as fast as the XUL trees.

The most difficult places have been converted (to using our tree-view custom element).
Remaining ones should be relatively straight forward (though not quite piece of cake):

• 19 cases for mail/: https://searchfox.org/comm-central/search?q=%3Ctree%5Cb&path=mail&case=false&regexp=true
• 6 cases for mailnews/: https://searchfox.org/comm-central/search?q=%3Ctree%5Cb&path=mailnews%2F&case=false&regexp=true
• 2 cases for calendar/: https://searchfox.org/comm-central/search?q=%3Ctree%5Cb&path=calendar%2F&case=false&regexp=true
• 1 case in chat/: https://searchfox.org/comm-central/search?q=%3Ctree%5Cb&path=chat%2F&case=false&regexp=true

Beware of outdated comments and dead code.
