QTextEdit changing color , after pasting some color data

[PstdEr]

Hi,
I dont know this is a strange problem , or silly but i am stumbled..

I am using the following code to format my QTextEdit.

whenever i paste some colored text from some other location the color is visible as it is and if i press enter
the text "EnterHere>" also changing to same color as pasted text.
I am using "EnterHere>" as command promt
I tried using AutoFillFormat(None) but did not help.

please let me now if any body faced this before.

QFont font("Arial",9,QFont::Courier,FALSE);
    setFont(font);
    QPalette pl;
 
    setAutoFillBackground(true);
    pl.setColor(pl.Base,Qt::black);
    pl.setColor(QPalette::Text,Qt::white);
    setPalette(pl);
    mPrompt = "EnterHere>";
    append(mPrompt);

QFont font("Arial",9,QFont::Courier,FALSE);
    setFont(font);
    QPalette pl;

    setAutoFillBackground(true);
    pl.setColor(pl.Base,Qt::black);
    pl.setColor(QPalette::Text,Qt::white);
    setPalette(pl);
    mPrompt = "EnterHere>";
    append(mPrompt);
