Re: [perl-win32-gui-hackers] Menus and NEM

[Jez W. <je...@je...>]

Interesting.

Now I know what the problem is I can use a work around (create a child
window within the main window being the parent, then attach all controls =
to
the child :) )

In an ideal world it should be fixed - but I can see the logic for not do=
ing
it.

In my case, I'm trying to convert my app to exclusively use NEM but keep
running into various problems - such as this one:) Most of my app is stil=
l
OEM...

Cheers,

jez.

Hello,

Looks like menus are indeed a little busted. You can't use both event mod=
els
on a menu. You can use either the NEM or the OEM, but you can't selective=
ly
use NEM here and OEM there. If you add a menu to a window that is using t=
he
NEM and your window uses OEM, your menu won't work. Your menu's event mod=
el
must match that of the window you're adding it into.

This is because menu commands are processed in their parent window's
wndproc, and the wndproc assigned to a window depends on the event model =
it
is using. A bit of bashing and hacking on my (and others) part could make
multi-event-model menus work properly, but I'd like to know if this
functionality is actually required by anyone. I mean, if you're a NEM use=
r
you're going to use the NEM for everything, and if you're an OEM user you=
're
going to use the OEM for everything. So is there any point to allowing yo=
u
to mix and match in menus?

I'm inclined to believe "yes" just for flexibility, but if I discover tha=
t
it looks too annoying to implement I might change my mind to "no".

Steve
