I'd like to get a simple notification after a TPropertyEditor.Edit is
done, basically because the event OnModified of TTIPropertyGrid only
works for the simple types (Ordinal, string) and not for TPersistent
sub classes (such as TStringList).

by following the flow of the calls i find this:

TPropertyEditor.Edit() calls
TPropertyEditor.SetPtrValue()TPropertyEditor.SetPtrValue() calls
PropertyHook.Modified();TPropertyEditorHook.Modified() calls the
global Forms function GetDesignerForm()GetDesignerForm() checks if the
global OnGetDesignerForm event is assinged.if so,
TPropertyEditorHook.Modified() will check if the resulting form has a
.Designer (TIDesigner)if so, the Designer.Modified will be called and
that's only where i can be notified
in short: i have to fully implement a custom TIDesigner, just to be
notified that a property editor dialog has closed !?

Isn't it a shame ?

Maybe i miss a simpler way out ?

TTIPropertyGrid.PropertyEditorHook.AddHandlerModified();

does the job much more simply.
