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 ) ) );

You can subclass QLineEdit and override keyPressEvent. QValidator is primarily for forbidding bad inputs as opposed to generating good ones, but for this simple case, fixup will probably do.

I'm not sure about the inputMask, but you can do it by subclassing QValidator, or you can use QRegExpValidator.
