TTIPropertyGrid OnEditorFilter not called for sub TPersistent
lazarus / 31-LCL

----------------------------------------------------------------------

If I inspect a TPersistent that publishes sub TPersistents, the event
OnEditorFilter is not called for the TPropertyEditor matching to the
publications of the sub TPersistents.

see attached sample.

Bug ?

You need to add {$M+} before the declaration of TSub to ensure all
properties are correctly published.


You also should make sure that you don't create a TStringList, a TSub
and a TRoot in such a cavalier fashion without freeing them after use,
because your code has horrible memory leaks.

No, I don't need to. TSub is already a TPersistent. Anyway this
doesn't solve ths issue.

But I guess that you don't get the problem: OnEditorFilter allows to
hide a particular property, but the event is not called for the
members of sub objects.

IRL this would allow me to hide some properties that are not
interesting at all, but visible because inherited from TPersistent or
TComponent (like .Tag or .Name). For example in this option editor
(based on TTIPropertyGrid), I can't hide the property Tag because of
this.
