Replace keyPressEvent (dot with tab)

[the_bis]

I have to get an IP address so I have four QLineEdit input box like this:

[    ] . [    ] . [    ] . [    ]

[    ] . [    ] . [    ] . [    ]

To copy to clipboard, switch view to plain text mode 

I can insert the first number in hte first QLineEdit (mylineEditGetAddressIP_A) and I can go to the second by pressing the tab key. My goal is to skip to the next lineedit also when I press the "." key.

This is my not working code:

(dialog object header):

[...]
private:
	bool eventFilter ( QObject * , QEvent * );
[...]

[...]
private:
	bool eventFilter ( QObject * , QEvent * );
[...]

To copy to clipboard, switch view to plain text mode 

(dialog object c++ code):

[...]
mylineEditGetAddressIP_A->installEventFilter(this);
[...]
bool dialogGetAddressObject::eventFilter ( QObject *object , QEvent *event )
{
	if (event->type() == QEvent::KeyPress)
	{
		QKeyEvent *keyEvent = static_cast<QKeyEvent *>(event);
		if ( keyEvent->key() == Qt::Key_Period )
		{
			qDebug () << "Event: Qt::Key_Period - Insert Qt::Key_Tab event...";
			QKeyEvent * myKeyEvent = new QKeyEvent ( QEvent::KeyPress , Qt::Key_Tab , Qt::NoModifier, 0);
			QWidget::keyPressEvent ( myKeyEvent );
			return true;
		}
	}
	return false;
}
[...]

[...]
mylineEditGetAddressIP_A->installEventFilter(this);
[...]
bool dialogGetAddressObject::eventFilter ( QObject *object , QEvent *event )
{
	if (event->type() == QEvent::KeyPress)
	{

		{

			QKeyEvent * myKeyEvent = new QKeyEvent ( QEvent::KeyPress , Qt::Key_Tab , Qt::NoModifier, 0);
			QWidget::keyPressEvent ( myKeyEvent );
			return true;
		}
	}
	return false;
}
