OK, forget the patch.

We already have one, it's called tabstop.

I will rephrase the question in my previous post. Suppose I have a grid with a read only TNxDBDateItem (has no sub items), should this be skipped automatically, as default behaviour?

Your right, I looked at the Delphi inspector and it stops at expandable items. But what about read only items that are NOT expandable (top level) items. Does it make sense to stop at those items?

Your example works as expected, gray (top level) items are skipped.

John Taylor asked “how can the Inspector be forced to focus the next editable item rather than categories that cannot be changed by the user ?�. The way I understand it he wants all read only items to be skipped. This makes sense to me.

Why do you want to stop at those read only top level items?
To expand them using the +/- keys?

This is really strange. I have tested it again and here it works fine.
Arrow keys up and down but also (shift) tab.
The read only top level items (TNxDBToolbarItems) are skipped.

Please post (or send me) a sample.
