Blitz/Amiblitz ScreenNotify Example?

[DisasterIncarna]

I have had a look at the screennotify include and unfortunately for clueless OS retards like me, it has no example of how to use it correctly, does anyone know how to correctly use screennotify to detect when workbench is closing and then reopens?

It's not a library I've used, but the include is just a very thin wrapper around the actual library interface, so usage should be essentially the same as with C. The Screennotify archive includes autodocs and an example program, so it should just be a matter of porting that to Blitz.

Hi,
I'm been trying to convert the c example from screennotify10 archive
with no luck...
I'm getting to the point where I read out 3, Workbench
Then I should read out true or false ?!
Any Pro that could help me out here ?

XINCLUDE "screennotify.include.ab3"

Port.l = CreateMsgPort("AB3_TemplateII.1")
succ2.l = screennotify_AddWorkbenchClient{Port.l}

snm.l = GetMsg_(Port) ; message ?
If snm <> 0 Then snm_Type.l = GetMsg_(snm) ; get message

NPrint snm

If snm_Type = 3 ; workbench ?

value = ?????

if value = false
CloseGUI{}
NPrint "close"
end if


if value = true
OpenGUI{}
NPrint "open"
end if


ReplyMsg_(snm)
End If

I don't speak Basic too well. I just used this to find out how to work with pointers and structs in Basic: https://eab.abime.net/showpost.php?p...69&postcount=4

If I adopt it right it should be like this:

*snm.ScreenNotifyMessage = GetMsg_(Port)
if *snm
	type.l = Peek.l(*snm\snm_Type)
	value.l = Peek.l(*snm\snm_Value)

	if type = 3
		if value = 0
			CloseGUI{}
			NPrint "close"
		else
			OpenGUI{}
			NPrint "open"
		end if
	end if
	ReplyMsg_(*snm)
end if

Thanks, It does make most sense but I can't get it working
*snm 1076732392
type 4194312
value 0
hmmmmm

I guess you dont have to Peek.l() the values of the struct:

type.l = *snm\snm_Type

will be enough.


Do you know if the screennotify.library still works with AmigaOS 3.2 ?
I tried to do a working example, but I do not get any messages when calling the menu item "Close Workbench".

Yes it works on 3.2, removing peek gives type 3

ReplyMsg_(*snm.ScreenNotifyMessage) and values 0 & 1 works as well

You dont have to add the datatype .ScreenNotifyMessage everytime just the first time to init it.

I do not get any message, how do you produce it?
Just trying to close the Workbench?

Change screen mode

Thanks!
That worked.
