Winwrangler does not work with xfce window manager

[Axel von Bertoldi]

The summary says it all. Using xfwm4 in Hardy. Winwrangler runs and apparently detects hotkey presses, but nothing happens. Example output when pressing a hotkey:

Got KeyPress! keycode: 11, modifiers: 84
Calling handler for '<Ctrl><Super>2'...
WinWrangler-Message: Hotkey <Ctrl><Super>2 for 'tile' activated
(winwrangler:17880): WinWrangler-DEBUG: Num windows: 2

(winwrangler:17880): WinWrangler-WARNING **: Desktop layout contains floating element at (0, 25)@1680x26
(winwrangler:17880): WinWrangler-DEBUG: Calculated desktop bounds (0, 25), (1680, 1050)
(winwrangler:17880): WinWrangler-DEBUG: Grid is 2x1, with cell size 840x1025

(winwrangler:17880): WinWrangler-DEBUG: set_geom(0, 25, 840, 1025)

Thanks,

Thanks for your bug report again :-)

It looks like the bounds are calculated correctly at least... I suspect that maybe xfwm4 doesn't implement the entire EWMH, but I could be wrong.

I just tried running 'wnckprop --set-x=40' (with xfwm4) on a Tomboy note window and this is what I got:

----------------------
mikkel@delight:~$ wnckprop --set-x=40

(wnckprop:6965): Wnck-WARNING **: Property _NET_WM_NAME contained invalid UTF-8

Action not allowed
mikkel@delight:~$
---------------------

And the window wasn't moved to x=40 as it should have been. This will need some more investigation...

[Axel von Bertoldi (bertoldia)]

Yeah, I get exactly the same here on a number of applications. Blame
xfwm4???

Hehe, yeah, I'd love to pass the blame on :-)

I'll have a better look at this when I find more time... But I am quite sure that xfwm4 is to blame, mostly because Compiz and Metacity works very well. Haven't tried KWin, but it ought to work as well...

Pasting my response to a comment on my blog entry: http://www.grillbar.org/wordpress/?p=306#comment-86735

"The commit message for revision 28313, 2008-10-19, reads “Add support for NET_MOVERESIZE_WINDOW” and I just checked the libwnck sources to see what wnck_window_set_geometry() uses, and this is exactly what it does…

I have not tried on xfwm4 > rev 28313 because it requires a lot of xfce4.5 packages that I don’t have time to compile myself. But it should work…"

So the bottom line: xfwm4 trunk should have fixed this. Marking this bug as Invalid.

THis was a missing feature in xfwm4 which is fixed in its trunk

Thank you for tracking this bug down.
