Thank you very much for your reply! As I mention in the mail before,
I'm trying to rewrite kimpanel with QML and DataEngine, the dataengine
part progress is well, but I have some problem in implement the UI.

I need a window to be always on the top to display the preedit and
candidate string, and this window will follow the cursor position, and
it should fit the content size within it. So it would resize and move
quite frequently after user input and focus change. AFAIK, the Plasma
Dialog edge hugging doesn't react immediately after the window move, I
don't want the preedit window to flicker.

So the only way is to implement with a simple qt window and paint it
with Plasma Svg?
