That's just a quick solution which I came up with and there are better solutions of course (Implementing your own line edit for example), but this works as I tested.

This is a SLOT:

void main_window::on_line_edit_0_text_changed( QString text )
{
    QString tmp = text;

    tmp.truncate( 1 ); // tmp is now first char of your text
    tmp = tmp.toUpper();

    if( text.size() > 1 )
    {
        text.remove( 0, 1 );
        text = text.toLower();
        text.prepend( tmp );
        line_edit_0->setText( text );
    }
    else
    {
        line_edit_0->setText( tmp );
    }
}

The connect:

connect( line_edit_0, SIGNAL( textChanged( QString ) ), this, SLOT( on_line_edit_0_text_changed( QString ) ) );
