QtCurve misbehaves on Kwin

[hackan301]

Ok so I haven't tried QtCurve with any other window managers here but I am going to draw the problem I have with QtCurve directly to Kwin.

When I have Oxygen or Bespin (only two other widget styles I have used) and have my System Settings/Window Behaviour set to place appearing windows in a specific way, let's say Centered, it works perfectly fine - But not when QtCurve is the set widget style.

While QtCurve is on all new programs end up in the upper-right corner. I could overrule it with adding Window Rules, but what I want is to get them dynamically centered - Something which is impossible with static Window Rules.

Anyone who has any idea about where I could begin investigating this?


Many thanks in advance / hackan

The original developer of QtCurve is no longer maintaining the software. Someone moved it to the KDE Projects site, but the code repository seems broken.

[hackan301]

Hm I see. It would be interesting to know if QtCurve behaves the same under a different window manager than Kwin. I could give Compiz a go.

[SteveRiley]

I could give Compiz a go.

Compiz on KDE? That will bring in a large handful of GNOME/Gtk packages. compizconfig-backend-kconfig looks like a useful package, too. Let us know how it works for you -- I suspect Compiz on KDE is uncommon.

[hackan301]

Yeah, haha, I suspect it is pretty uncommon. I tried it on just for the heck of it a couple of years ago on KDE and it was a disaster, haha!

At here...

Tested with the Kubuntu 14.10 / Plasma 4

QtCurve 1.8.18 git snapshot 2014.08.03




Turning on:

- widget style QtCurve
- window decoration: QtCurve
- window placement: Centered




At here, most of the applications are launching the window to the center.




Few Qt 4 / Qt 5 applications seem to have own start point.

QtCurve

As told at the QtCurve github : https://github.com/QtCurve/qtcurve

QtCurve has recently switched hosting locations to the KDE infrastructure.

The new repo URLs are:

read-only: git://anongit.kde.org/qtcurve

read-write: git@git.kde.org:qtcurve

web: https://projects.kde.org/projects/pl...rve/repository or http://quickgit.kde.org/?p=qtcurve.git

Something to try

Have you tried with the new user to exclude the damaged configuration files ?

[hackan301]

No, I haven't tried with a new user account yet, that is an interesting theory, will try it.

Maybe there's some differences between QtCurve versions also, I am running: 1.18.14

[hackan301]

Alright the outcome is somewhat interesting. It seems that what makes QtCurve place new application windows in the upper-right corner is - wait for it - Window Opacity!

It's the darnest thing, in my theme I have window opacity set to 80%, pulling it back up to 100% makes new application widnows appear according to KDE window behaviour settings.
