[Fedora-i18n-bugs] [Bug 1851862] New: input into Qt4/Qt5 with ibus does not work when using Gnome Wayland

https://bugzilla.redhat.com/show_bug.cgi?id=1851862

            Bug ID: 1851862
           Summary: input into Qt4/Qt5 with ibus does not work when using
                    Gnome Wayland
           Product: Fedora
           Version: 32
            Status: NEW
         Component: ibus
          Assignee: tfujiwar(a)redhat.com
          Reporter: mfabian(a)redhat.com
        QA Contact: extras-qa(a)fedoraproject.org
                CC: i18n-bugs(a)lists.fedoraproject.org,

  Target Milestone: ---
    Classification: Fedora



The input modules for Qt4 and Qt5 seem to be installed:

[mfabian@localhost lineedits]$ rpm -qf
/usr/lib64/qt4/plugins/inputmethods/libqtim-ibus.so
ibus-qt-1.3.3-24.fc32.x86_64
[mfabian@localhost lineedits]$ rpm -qf
/usr/lib64/qt5/plugins/platforminputcontexts/libibusplatforminputcontextplugin.so
qt5-qtbase-gui-5.14.2-5.fc32.x86_64
[mfabian@localhost lineedits]$

I did set the environment variable QT_IM_MODULE=ibus

I used the lineedits examples for testing:

[mfabian@localhost lineedits]$ rpm  -qf
/usr/lib64/qt4/examples/widgets/lineedits/lineedits 
qt-examples-4.8.7-52.fc32.x86_64
[mfabian@localhost lineedits]$ rpm  -qf
/usr/lib64/qt5/examples/widgets/widgets/lineedits/lineedits 
qt5-qtbase-examples-5.14.2-5.fc32.x86_64
[mfabian@localhost lineedits]$

I am using ibus-anthy for testing ibus input, but it doesn’t matter which ibus
engine is used.

When using the Gnome Xorg desktop, I can input with ibus-anthy into both the
Qt5 and the Qt4 lineedit examples.

With the Qt4 lineedit example, I can choose by opening the context menu with
the right mouse button between using xim and ibus. Both works.

Qt5 does not support xim, so this option does not exist, but ibus input works.

Now when using the Gnome Wayland desktop, I can only input when using the "xim"
option in Qt4.

With the "ibus" option in Qt4, ibus input does not work. And in Qt5, ibus input
does not work.

To summarize:
=============

ibus input using the ibus modules does not work in Qt4 and Qt5 when Gnome
Wayland is used,
it works in Gnome Xorg.

--- Comment #1 from Mike FABIAN <mfabian(a)redhat.com&gt; ---
Copying this file makes it work (Fujiwara San told me that):

[mfabian@localhost bus]$ cp 8e6ab773e4094f2db140fb3b3068ba27-unix-wayland-0
8e6ab773e4094f2db140fb3b3068ba27-unix-0
[mfabian@localhost bus]$ 

8e6ab773e4094f2db140fb3b3068ba27-unix-0 did already exist, probably from the
previous log in into the Gnome Wayland session. But it contained wrong
information.

I will fix ibus-qt after qt5 is fixed.
