I'll see if the same happens to 1.9.8 and fix it using 'make debtargz' as you've pointed out.

I agree.
I have (unsuccessful) try to post a similar mail in the fpc pascal
list.
But what do you mean with published methods? The published section is
intended only for properties, which should be published in the object
inspector. I guess you mean event methods. Beside event methods,
callback functions and virtual methods could be affected too.
My main problem, if I hide the hint by using
{$HINTS OFF}
...
{$HINTS ON}
I remove all useful hints as well.

But IMCO this is not really a good OOP-like solution. Above all because every class in the unit have access to all sections of a other class, including the private section (at least in Delphi). A real private section is on my wish list since Delphi 1. Sometimes is it not possible or meaninful to put all related classes in 1 unit, e.g. to avoid monster units and split a problem in surveyable parts, although this classes belong together and are managed by a furthermore class. Then you need to publish more methods, as you need for other resp. the actual usage, this softed the information hiding concept. Years ago I read a description of a object oriented pascal dialect, which use a other concept, IIRC called view concept. The developer can declare different views to a class, which only contain the methods, which are needed for a concrete problem. I think such a concept would be the better way. The developer of a class or component don't need to consider, which methods / fields he need to set in the protected part. A developer which derive a class can define, which methods / fields he need and write a view without any hacks or modification of the origin class. wkr Peter. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
