How to disable the automatic addition of rows in the list by pressing the button Enter?

What do you mean exactly? I put a combo box on a form and tried -- nothing I typed in was added to the list.

Lazarus SVN: 23755
In the box write something. Press Enter. The list (Items) adds a new row with the text of the input field. If you click again Enter, then the changes will not happen. But changing the text in the box and pressing Enter - get a new line in the list (Items).

I couldn't recreate what you say with svn 23803 (this morning's). Sorry.

In 23803 it is disabled by default?

I have never seen the behaviour you describe, I'm afraid I didn't understand you completely.
Do you actually mean you do not want to be able to type in at all? Then you should put Style = csDropDownList.
But, if Style is csDropDown (the default), what you type is not added to list anyway.

Yes, in the GTK2 this does not happen. But in QT 4.5 it is.
I would somehow bypass it at the moment KeyDown.

It's probably a Qt bug then. You should report this in bugtracker.
