All Torrents screenshot

Can't seem to reproduce

Hmm... Just try the following steps:
1. Make tab 1: show All torrents
2. Make tab 2: show Active torrents
3. Choose tab 1
4. Add torrent, start download
5. Minimize to system tray
6. Wait until torrent will be downloaded (and finish checking chunks)
7. Restore KTorrent window
8. Now you on the tab 1. Choose tab 2.
9. Now you can see the incorrect chunks line

If it is helpful I attache my ktorrentrc file below.

Qt-4.7.1

I can observe the same phenomenon. The important point is that the KTorrent window is closed and ktorrent is only visible as an icon in the system tray. Then a check has to be executed. Now, when opening the main window again, you will see the misplaced torrent check. If several checks have been performed, the output of all of them is on the same place, so you absolutely can not read any of the numbers.

I opened new bug 264215 is might be related to this. As bug 248205 is depend on several opened tabs think this may depend on the several opend tabs situation too.

Is this actually still reproducible with the latest code from git ?

Yes. Confirm this with latest git.
For small torrents, the chunk bar invalid only in tab 2. But for big (over 1 GiB, not tested the real size level) the bug appears in both tab 1 and tab 2.
The problem with tab 2 is a problem due the bug 264215.

Backport to 4.1: Update view tab when switching to it, fixes data scan widget showing in the wrong place

The bug exists in latest Git.
Don't understand how update() will hide chunk bar. In the bug 248205 you create method View::extend(bt::TorrentInterface* tc,Extender* widget). Think this method should be applied in ViewManager::onCurrentTabChanged() or call tree.

update() will hide all widgets of items which are not visible

Ok. I try to clarify the problem.
You expect that extenders will hide in ViewModel::update(ViewDelegate* delegate,bool force_resort):382.
Callback:
ViewManager::onCurrentTabChanged(QWidget* tab):264
View::update():140

They are not.
The situation when in tab 2 (Active torrents) there are no torrent actually active.
Local variable "hidden" is true for discussed torrent because the group "Active torrents" has no torrents.
Also Item::hidden is true.
So the result of expression at 376 is false. And hide action isn't executed at 382.
Also I noticed that the torrent in tab 2 (from ViewModel::torrents) hasn't been updated (it's been updated in tab 1), beacsue has wrong status "bt::ALLOCATING_DISKSPACE", and not updated info (bytes_downloaded, bytes_uploaded, etc).
So, the problem I think is: we start torrent in tab 1, the torrent became visible in tab 2 (because it will be downloaded and active). The torrent in tab 2 didn't change hidden value, but the extender started. Then KTorrent didn't change the value because expect that the torrent already changed status to hidden and hide extender.

There are 2 solutions:
1. Try to hide extenders for all torrents (otside "if" statement at 376-383)
2. Correctly update actual infromation (Item object) for torrents after changing tab.

In addition, if behavior will be this: after changed to tab 2 (Active torrents), the torrent still was active, but seconds later peers were disconected and the torrent became not active. The update() function still be executed every timer tick, so the problem will be gone because the hidden status will be changed.

This solves the problem.
