It seems that you're using our very old API. startComposition()
and endComposition() had already been obsolete. Please use our
latest 'unified patch' for development.

Download qt-x11-immodule-unified-qt3.3.2-20040812.diff.gz from
following page and see src/kernel/qinputcontext.cpp for the API
description.

Backspace key can be filtered by ordinary input context. For
example, uim-anthy input method can delete preedit characters by
backspace key.

Our immodule API provides no way to do it. Please show us why
it's required.

Although the XIM input method in the official Qt release commits
characters via QKeyEvent for many languages, we had decided that
always committing composed characters via QIMEvent. I could
explain detailed reason about this in next reply if you want.


In addition, please show me your code. It gives me more
information about what you're thinking.
