Libelektra: QT-GUI does not support multiline metadata correctly

[ghost]

Metadata with much text simply gets printed over multiple lines, which results in overlapping text if additional metadata is present below.

System:

qmake --version
#> QMake version 3.0
#> Using Qt version 5.5.1 in /usr/lib/x86_64-linux-gnu

cat /etc/os-release
#> NAME="Linux Mint"

Thank you for reporting!

@0003088 Do you maybe have time to fix this?

[0003088]

This issue looks vaguely familiar, I think I tried to fix this already back in the day (to no avail obviously). I can make a few tests but as far as I see there have been no additions to the QT TableViewColumn type since 2015 https://doc.qt.io/qt-5/qml-qtquick-controls-tableviewcolumn.html

To me it looks like an rendering error in the qt engine itself.

Thank you for looking into it! Is this problem reported in the QT issue tracker?

[0003088]

Doesn't look like it, guess I could file one during the next days. Has this happened with the latest version of QT? Should be 5.12.1.

@Piankero Please tell us the OS and version of QT.

I looked into this again and it's in fact not a problem with the TableViewColumn, but with the Text delegate. The problem are obviously the newlines, by default Qt just renders them as they are

There is the possibility to 'elide' them, so only the first line is shown and dots indicate, that something has been left out

Obviously not ideal. It is however supported to check if elide mode is in effect so maybe a solution would be to create a mouse field that is only active if elide is on and displays the whole text on hover?

BTW I would recommend to update Qt, 5.5 is _very_ old.

Sounds like a good plan! Maybe the text can be done a bit longer before being elided? Or do already two lines create an overlap?

I just realized that I cannot save changes in the metakeys? Is this a known issue? It works if I create a new key, assign it a metakey and synchronize. But if I want to change an existing metakey, the changes are gone after sync/restart.

[markus2330]

Thank you for spotting and reporting this problem! No, it is not a known issue, setting meta-data on the commandline works without problems:

kdb setmeta user/something abc def
kdb getmeta user/something abc
#> def
kdb setmeta user/something abc def2
kdb getmeta user/something abc
#> def2

Maybe the problem is in the 3-way merge, which is currently being reimplemented because of many known problems.
