Description Takuro Ashie 2013-06-29 08:50:56 UTC
When I try to input Japanese string via IME on a text widget, composition string isn't shown on it.

On the other hand, when I continue typing then commit the string by pressing "Enter" key, a result string is correctly entered to the widget. And I confirmed that "System (Windows IME)" in the "Input Methods" menu in the context menu of the widget is correctly selected. So IME seems work.

Although a similiar issue is fixed recenctly,


I think that the issue I met is different problem, because

* It's also reproduced on standard GTK+ widgets.
* No preedit string is entered (the caret doesn't move). Not a color issue.

FYI I also using GTK+ on windows (gtk+-2.24.10) with my some products, I have not seen such a problem on them.

I recently fixed an issue where the first preedit string would not be rendered: https://github.com/mono/monodevelop/commit/37ebb263107972de4cc0b68fe159a014c0c5b2cf

Though if GTK+ widgets are affected too, then it sounds like a gtk+ bug.

Confirmed, seems to be a GTK bug since it affects GTK entries too.

I updated GTK+ in my products to 2.24.20 and tested it.
I can't still reproduce this issue with it.

We have prepared a new build of GTK+ that contains a fix for this issue. To test it, please download https://mjhutchinson.com/files/temp/gtk-2.24.20-2013-07-11.zip and copy the directories it contains "C:\Program Files (x86)\GtkSharp\2.12". You can verify it is installed by checking that "Help->About->Show Details" shows "GTK 2.24.20".
Comment 5 Mikayla Hutchinson [MSFT] 2013-07-11 20:17:02 UTC
I have verified that this fix works on my machine.

I confirmed it on my environment.

It works fine for me too.

The new GTK+ binaries have been included in the GTK# 2.12.22 installer, which is now in the beta update channel and will roll out to stable after we're reasonably confident there are no regressions.
