Alright, a couple of tufts of hair later and I'm still no further on with
this stupid problem. Someone, please rack your brain and tell me what I'm
doing wrong.
In a vain attempt to try and locate the source of this problem I've changed
a few things in my code:
- I've removed any reference to the userdata I was providing. Which as it
turns out, didn't make any difference. The application still crashed.
- The only remaining message I deal with in my despatcher is now OM_NEW,
which calls the function below like this:
#ULONG SAVEDS ASM MCC_Message_Despatch(REG(a0,struct IClass *cl),
REG(a2,Object *obj), REG(a1,Msg msg))#
# {#
# switch(msg->MethodID)#
# {#
# case OM_NEW:#
# return MCC_Message_New(cl,obj,(APTR)msg);#
# }#
##
# return DoSuperMethodA(cl,obj,msg);#
# }#
#ULONG SAVEDS MCC_Message_New(struct IClass *cl, Object *obj, struct opSet
*msg)#
# {#
# /* create class */#
# obj = (Object *)DoSuperNew(cl, obj,#
# MUIA_Window_ID, MAKE_ID('T','E','S','T'),#
# MUIA_Window_Title, "Test Window",#
##
# WindowContents, VGroup,#
# Child, SimpleButton("Test"),#
# End,#
# TAG_MORE, msg->ops_AttrList);#
##
# if(obj)#
# {#
#DoMethod(obj, MUIM_Notify, MUIA_Window_CloseRequest, TRUE,
obj, 3, MUIM_Set, MUIA_Window_Open, FALSE);#
# return((ULONG)obj);#
# }#
# }#
As already mentioned in the previous email, I add this new window on demand
with the following calls:
#newwin = (Object*)NewObject(MCC_Message->mcc_Class, NULL, TAG_DONE);#
#if(newwin) DoMethod(app, OM_ADDMEMBER, newwin);#
Everything works fine, as it should I imagine, but as soon as I press that
close window gadget, it's goodnight. Reset required. Having a look at the
stack trace I can see the last MUIish call is MUIP_FreeVec()
Can anyone please see anything wrong with the way I'm doing this? Last
attempt before I scrap the whole lot until next year, I can't be done with
crappy Windows programming at work and this is stressing me out even more
at home now :-)

Daniel
