How to create custom slot in Qt Designer 4.1?

[cioannou]

For example, you declare a slot in your app.h file:

private slots:
...
	void searchAll();

private slots:
...
	void searchAll();

To copy to clipboard, switch view to plain text mode 

That's exactly what I am trying to avoid.
If I change the app.h that is generated by the designer and afterwards add some new widgets to my dialog, all my private slots will be lost.

Am I missing something?
