Shift Select (click) to select a range of torrents does not work (QTBUG-115838)

[ackerthehacker2]

qBittorrent & operating system versions

qbittorrent 44.2
OS: Mac OS 12.3.1 Intel
Qt 6.2.4
libtorrent 2.0.5

What is the problem?

One cannot use shift click to select a range of file (standard Mac operation).

Command -click works individually
Command-A select all

but if you want to select a range, you are stuck.

Steps to reproduce

On. Mac in qbit. click on TORRENT ...
go down two or more and hold the shift key when you select

Additional context

The is standard Mac UI

Log(s) & preferences file(s)

No response

Seems like a regression in Qt6: #11768

[ackerthehacker2]

Yep .. I searched for shift click instead of shift. mouse click ...

It doesn't work sometimes in Windows too after QT6 upgrade. If you select end of range with shift, it selects just the last line instead. You can select range just by dragging with pushed left mouse button over lines. It is not so precise, but might work for some cases. It might help if you push every shift, alt, ctrl at keyboard to remove the effect. Not sure, if it always help, more like a ritual.

@thalieht This seems to be fixed in Qt 6.3.1 (at least on windows)

@DarkVoyage
Can you confirm with below test builld?

tested 4.4.2 (based on Qt 6.2.4) and 4.4.4 (based on Qt 6.3.0) official builds on Intel-based and M1-based MacBooks running the same version of macOS (12.5.1) - issue is reproducible only on Intel-based, everything is fine on M1 even with Qt 6.2.4

very strange that Shift + Up/Down arrows works, but not with mouse. in case of mouse it looks like it selects as it should for a moment, but than "single click" event is fired for the last selected item and selection disappears.

this is definitely not a qBittorrent bug, this is something inherited from Qt. also this is another confirmation that macOS for M1 and Intel are different things (since 12.5 difference became is much more noticeable, but previously it also can be found). if summarize in few words: macOS for Intel is something that "just exists" and nothing more, and macOS for Apple Silicon (i.e. M1/M2) is something developed in direction very close to phones rather than computers. degradation...

P.S> I don't have personal MacBook, h/w I used for testing I got from the office due to work responsibilities. and I'll return it very soon.

I've tested 4.4.4 QT 6.3.0 Windows 10 x64. No problem anymore. But it has a little strange behavior, if you still hold SHIFT then click further and keep holding left MB and drag cursor a little in list (up or down) - then you lose selection and it selects just this row or two rows like you don't hold SHIFT at all. But if you still holding SHIFT and click any row again - it will restore previous selection. This dragging is very little, sometimes you click and selection is lost, but it is because it felt small dragging. So not a bug (maybe). There's no (and can't be) such problem with arrow keys, because there's no dragging, just discreet action. So maybe this list dragging has sensitivity in pixels, I think I saw such a setting in some programs.

Also a remark that dragging cursor through rows with LMB while holding shift or ctrl has specific behavior, different to clicking. While ctrl allows adding to selection in any direction and order, shift has effect of canceling some selected items that are outside of range.

I can no longer seem to reproduce this with the use of Qt 6.5.1

Is there any qBittorrent macOS build with Qt 6.5.1? Mine is 6.4.3.

4.5.3 had Qt 6.5.x https://www.fosshub.com/qBittorrent-old.html

@xavier2k6 The issue is still present but doesn't happen always, with qbittorrent-4.5.3_lt20.dmg.
Hold the shift key and keep selecting up and down and eventually it will select only the last one. The first click I'm not holding the Shift key, then all the time.

[xavier2k6]

issue is reproducible only on Intel-based, everything is fine on M1

@superbonaci comment above may still be relevant...

You could also test with the latest master branch which uses Qt 6.5.2 & see if it makes a difference for you.

I'm on M1 too.
Testing qBittorrent-CI_macOS_GUI=ON_libtorrent-2.0.9_Qt-6.5.2.zip still same issue. Sometimes select properly and other not, holding shift all the time:

@superbonaci
Could you report it to Qt?
