keyPressEvent and auto completion

Hello,

I'm trying to do an auto completer for parenthesis but when I insert ")" in my QPlainText while "(" key is pressed I get ")(" instead of "()". That 's propably because the inserted text is written before the pressed key. How could I do?
Tanks for your help.

PS: I don't want to use keyReleaseEvent because this is lagging to much.

Any idea of what the setKeepPositionOnInsert should do?

I thought of using scintilla in my qplaintextedit but I wonder if it's possible? I saw the qsciscintillabase doc and it says that low level API are implemented on it.

In fact I don't have any idea how to implement indentation without qscintilla.

Could you simply give your idea?

I finally achieved to code my "indentor". If someone is interested in it just send me a PM:cool:
