I am studying Chinese and use the composite key when writing pinyin.
However I have the problem that it doesn't produce consistent results, see below.

Code: Select all

Combination  Firefox    Any KDE program
Comp. + c    ǎěǐǒǔ      ǎěǐ©ǔ
Comp. + -    āēīōū      ãēīõū

Any tips on how to fix this?

Does this occur in a pure Qt application such as Arora or qtconfig?

Yes, I just tried with Arora - same problem there.
So I guess it is a Qt bug/feature then.

Or could it be ibus?
Ok, not ibus. Tried both shutting ibus down and starting Arora with XMODIFIERS=''

For some time I have had to give up composite keys either on GTK apps or Qt apps.
Try disabling/enabling iBus for a Qt application without closing it. Open the contextual menu on a textbox for the test application, look for "Select input method" and try each entry by writting some text with composite keys.

For me, XIM works bad with Qt apps, but iBus plugin for Qt gives the best results.

Thanks for answering. I tried changing to XIM in kmess, but then the composite key stopped working altogether for some reason.
