Dead keys lost

[anacharsis]

Can't type ê nor ë in edit window of
geany 1.34.1 (built on 2019-05-01 with GTK 3.24.1, GLib 2.58.2)
using GNOME 3.30.2 on my old laptop ASUS N73JF with a french keyboard running
Fedora 29 (kernel 4.20.15-200.fc29.x86_64)
I just get e.
GNOME Terminal accept those unicode (UTF8 encoded chars), I can type them in Geany's terminal plugin, copy-paste them in the edit window, but not type them in edit window.

On the same device (mutliboot)
geany 1.32 (built on 2018-08-01 with GTK 3.22.26, GLib 2.54.1)
GNOME 3.28.2 running
Ubuntu 18.04.1 LTS (kernel 4.15.0-46-generic)
works fine.

I love old Geany but new rolling Fedora is attractive.

Sounds more likely to be the GTK or Gnome versions, can you try the same version of Geany on both systems.

[anacharsis]

Thanks for your prompt comment elextr.
I build from source (on Fedora 29):
./geany -V
geany 1.32 (built on Mar 19 2019 with GTK 3.24.1, GLib 2.58.3)
(GLib 2.58.2 updated to 2.58.3 last night!).
The problem is still there.

Going to study GTK-3.24.1 behavior with dead keys in edit windows (as it seems the easiest place to dig in).

[anacharsis]

I download source of SciTE and run
make GTK3=1
under scintilla/gtk/ and scite/gtk (on Fedora 29).
SciTE runs almost fine from the command line... But the problem is still there, and it shows:
Gdk-Message: 21:36:23.603: Window 0xee4c80 is a temporary window without parent, application will not be able to position it on screen.
each time I type " or ^ dead key.
A curious thing: I can type ^e in a search/find dialog without any problem (I get ê).

Where to dig now?

[elextr]

@anacharsis since the problem is GTK version dependent probably you have to dig into GTK keyboard handling. Also I don't suppose that your locale and your keyboard layout are different, that is likely to cause problems?

[anacharsis]

I install a dayly build Ubuntu 19.04 (kernel 5.0) under VBox, and a (not snap) Geany:
geany -V
geany 1.34.1 (built on 2019-30-01 with GTK 3.24.5, GLib 2.59.3)
It runs fine. My problem is not GTK version.

[elextr]

@anacharsis if I read your above correctly you have:

Geany	GTK	Works?
1.32	3.22.6	yes
1.32	3.24.1	no
1.34.1	3.24.1	no
1.34.1	3.24.5	yes

which looks like 3.24.1 is a dud GTK version to me.

[codebrainz]

@anacharsis does it work if you run Geany like this?

XMODIFIERS="@im=none" geany

I've got the same problem in the official binary of fedora 29 distro. Solved by running geany with the following command:
GDK_BACKEND=x11 geany

It seems to be a problem with wayland gdk.

[anacharsis]

@elextr
See João Alves: I think gtk <-> wayland interactions need some more care.

@matthew Brush
Command line
XMODIFIERS="@im=none" geany
produces
Gdk-Message: ... : Window ... is a temporary window without parent, application will not be able to position it on screen.
dead keys still lost.

@joão Alves
Command line
GDK_BACKEND=x11 geany
runs geany fine (no dead key lost).

Thanks so much: I love Geany for so long...

[anacharsis]

To use Geany directly, add
export GDK_BACKEND=x11
in my .bashrc, et voilà.
