How to setPlainText() without emit textChanged(), QPlainTextEdit

[MaQzma]

Hi,

Is there any way to call "QPlainTextEdit::setPlainText()":http://doc.qt.nokia.com/4.7-snapshot/qplaintextedit.html#plainText-prop without emit "QPlainTextEdit::textchanged()":http://doc.qt.nokia.com/4.7-snapshot/qplaintextedit.html#textChanged signal?

I just want that textChanged() signal will be emited only when the user changes the text, not when I use setText(), clear(),...

Thx.
