IDE Windows Centered

[sfeinst]

I don't know if this is specific to QT, but since I was trying this with QT, posting here.

I am running Debian Trixie using Gnome as desktop

I downloaded fpcupdeluxe and installed v4.0 of lazarus with fpc 3.2.2.  I loaded Lazarus, and chose to rebuild the IDE but with QT6 widgetset.  I also tried downloading fpcupdeluxe qt version and installed the same (but fpcupdeluxe builds as qt instead of gtk when I use the qt version of fpcupdeluxe).

In both cases, when I startup the IDE, all windows are centered on the screen.  I moved them to their correct locations for me (main ide on top, object inspector on left, messages on bottom and editor in middle).  Closed the IDE and reopened, same thing.  All windows centered.

Am I missing a setting somewhere?  Does qt6 have issues with gnome and wayland?  Not sure what is going on.

Very likely Wayland issues, cause Wayland does not support setting window positions (and while there's a feature request for a suitable protocol, the maintainer of the Gnome compositor already said that they're not interested in supporting it).
You can try to run Lazarus using X11 backend (I don't know which parameter you need to pass to Lazarus so that Qt picks the X11 backend) cause Xwayland has some additional functionality here to do window positioning nevertheless.

Thanks,

Thought it might be Wayland.  Interesting gtk2 works ok.  I did try to rebuild Lazarus using gtk3 and had the same issue (actually a bunch of other issues too - but that would be a different thread).

Thought it might be Wayland.  Interesting gtk2 works ok.  I did try to rebuild Lazarus [4.0] using gtk3 and had the same issue (actually a bunch of other issues too - but that would be a different thread).

Since you are already using fpcupdeluxe, can you test with Lazarus 4.4 + gtk3 and Lazarus Trunk + gtk3?

I did try Lazarus trunk with gtk3.  A few issues (with centering being one).  My next thing to try is still using qt6, but I installed anchordocking for ide.  At least that way the Windows will be in their correct places.  I don't normally use the one window thing, but it is a compromise worth doing if qt6 works for the rest.  I'll be playing around with it.

Naturally, gtk2 doesn't have wayland backend.
