Title: It's monday....time for another stupid MUI-question ;)
Post by: Kronos on September 22, 2003, 08:55:07 PM

O.k. I allready discussed this sometimes ago with itix on irc, but it
seems that I'm just to slow  even for the easiest instructions  .....


I got a costum class,and this should have an extra attribute, which I than
want to use as trigger for an Notify-method.

I know that it has something to do with OM_SET/GET, but how do I make sure
that the attribrute is actually checked forafterI set it ?

I do get a bunch of OM_GETs at app-start,but none afterwards ....

You simply need to forward the OM_SET message to your superclass. This is a snippet code from the UAE gui I'm writing for AROS (btw, why the hell isn't the

Code: [Select]

... bbcode available, uh?:

struct TagItem *tags, *tag;

for
(
    tags = message->ops_AttrList;
    (tag = NextTagItem(&tags));
)
{
    switch (tag->ti_Tag)
    {
          ....
    }
}

return DoSuperMethodA(CLASS, self, (Msg)message);

Sorry for the bad indentation, but without the [code] thingie I couldn't do better.

You mean you want to be notified when your attribute has been changed?

Tell you, both MUI and Reaction's API suck ;-) What's needed is a clean, C/C++ style compliant...;-)

Sorry Kronos, I don't actually know the answer so I'll shut up now :-)

@Karlos

More the other way round.

I want the app to be able to check the attribute via a Notify that I setup
at progstart. Than I want to set the attribut inside my class, and the
app should react according to that notify.

Yes I did,but until right now had no time to try ....

Seems to work o.k. sofar.

@Karlos
That isn't really a special MUI/ReAction-prob ....
I stillcringe when I remeber how long it me to find out how to set the
IMsg->code in a GadgetUP-event coming from my boopsi-object
(based on RKRMBut)  :-x  :-x

There is a C++-wrapper for MUI,so that wouldn't be a prob. And writing
better doku for that sounds somewhat easier than writing a new GUI-lib
AND a good doku for that  :-o
