Ffenestri (multiple host window support), and Mac Host Menus

The 3.10 team asked me to build a change set for Ffenestri  (multiple  
host window support), and Mac Host Menus for 3.10.
The last change set was build for Tweak in 2004.

I've updated my ftp site and my idisk in the Ffenestri folder found  
in the experimental directory with a number of new
change sets that let you load the Ffenestri logic into a 3.10 image,  
likely also into a 3.9 image. Testing shows that this re-released  
code works with Mac PowerPC and MacIntel.  I did uncover a byte order  
problem on macintel btw.

For the additional Macintosh Host menu support, used by Sophie, and  
by Scratch I've also pushed out a set of change sets
to allow one to load that logic into a 3.10 image, likely also into a  
3.9 image too. Testing shows that this re-released code works with  
Mac PowerPC and MacIntel.

I did NOT revisit the Tweak support, there seems to be a LACK of  
interest. Anyone who wants to explore that should email me and I'll  
point out the methods of interest they can rework for Tweak.  Of  
course for Tweak you can open a tweak project in a host window and  
expect everything to work since the display and event queue are  
instance variables, not globals like in Morphic.

I don't have either a Mac or a RiscOS box, so I'm not entirely clear
as to whether Areithfa Ffenestri does something useful now, or if
it's more of an R&D exercise awaiting future development work.

It would; and I can't find anything in my mailfiles to suggest that  
it has been done yet.

Right now it is a bit of both. The low-level stuff seems to me to be  
complete but we need the higher level stuff to actually make sensible  
use of it.
You can:-
   create
   decorate
   show
   hide
   delete
   move
   query state
   display on
   get event info from
host windows. John did some hacks to map Squeak projects to windows  
as a proof of concept but I don't think that is the way to go. I'd  
rather see it having any morph in a separate host window, including  
allowing pasteupmorphs (I think that's the chap) so that you can do  
something MDI-like if you really want to. John also did host menu  
stuff and it appears to work ok on Windows as well. I'd recommend  
having a pesudo-platform that provides sorta-host popup menus by  
using an undecorated window to display a Squeak menu as well - since  
Mac and Windows host menus are so utterly f**%#ed up. In my opinion.  
Which is, of course, The Truth.

Well actually it was to map tweak projects to a window because a  
tweak world has a display surface and an event queue. So when the VM  
flows the events
we dispatch the event to the proper tweak world event queue based on  
which host window the weak world thinks it is managing and possibly  
alter the coordinates.
  And when the tweak world draws to the tweak surface we ensure it  
draws to the proper host window surface.

Normally the tweak project's event queue would just be filled with  
events based on focus, and the surface used would be Display.

Worked quite nicely, not a HACK....

What was a hack was the Morphic project integration I did. On a  
morphic project switch I would switch out what the Display was, and  
of course on
window activation ensure the correct Morphic project was switched to  
and the events for the proper window would flow. Because the logic in  
2004, perhaps today, assumes only one morphic project was running  
that was reasonable.

In all of this, if one looks at the SUnit you'll see how to interact  
with a window and draw to it without any regard to what Morphic thinks.

Sadly looking for Sensor and or Display usage will cause one's blood  
to run thin... The fun part is that in *lots* of usage there is no  
context to decide which
drawing surface we are dealing with...

It's 5.36 here and just reading all.
Later I report any relevant issues.

Again I said you John  are not a master, you are one indispensable Squeaker.

All SUnit test are green.
The quit command of new menu do not works. Ask for save or no , but no
quits.
The usual World menu is working, if this helps you

Host Windows are nice !!!!

Hi guys

Do you think that this is reasonable to rescue this project. Because  
after reading your comment I have the impression that
I was wrong suggesting to have a look at what you did.

Well the host menu quit command does is


        applicationQuit ifNotNil: [applicationQuit handler:
                [:evt | Smalltalk snapshot:
                        (self confirm: 'Save changes before quitting?'
                                orCancel: [^ self])
                                andQuit: true]].

mmm well that is wrong, SmalltalkImage current...
and the error handler in the menu  handler code traps the error so  
you don't see it.

I've posted a fix to my ftp site and idisk.

Yes this is why I was mentioning it for 3.10 but if this is not ready  
what should be done? May be some people
may join and do something.

Stef

Ok, well all I did was spend some time to confirm that the host  
window and mac menu support works in a 3.10 image, plus works for  
macintosh
powerpc and macintel. I believe Impara has a windows VM for the host  
window plugin but I'm not sure where.  Having one for unix would be  
great too.

Both Sophie and Scratch use the mac menu logic, so that is in actual  
use. However no-one I know is using the multiple window support.

Actually, if I am not mistaken, the regular Windows VM has had host  
window support built-in for quite some time.

All what John send works fine, he is working a lot with this.

I ask he and repeat for all what have Mac and knowledge of Quartz Composer
if some kind of Squeak drive is possible.

I mean some like the attached file could be generated inside Squeak (not in
Quarz Composer) but performed into a host window.

Maybe I again ask stupid things :=)

Edgar

Ah, well could someone could load the Ffenestri change sets I posted  
into an image and try running the Sunits on a windows machine?

     For what it's worth, as I mentioned in a Spoon progress report[1],
I'm building the Spoon display support from the Ffenestri work.


     thanks again!

mmm.

Well in Sophie we set things up to allow quicktime to draw to a  
surface.  What we do is setup a GWorld via FFI and call our
quicktime plugin to setup a squeak surface that points to the the  
GWorld. Then we tell Quicktime to draw to the GWorld, the
plugin is setup to signal a semaphore when quicktime has finished  
drawing a frame. So we wait on the semaphore, and when
fired we flush the form to Display.

For the browser plugin I use this to create a CGBitmapContext

SharedBrowserBitMapContextRef = CGBitmapContextCreate  
(SharedMemoryBlock,width,height,
8,rowBytes,colorspace,kCGImageAlphaNoneSkipFirst);

then later do
                CGContextDrawImage(SharedBrowserBitMapContextRef, clip, image);    
to draw to this bitmap
or
                CGContextDrawImage(targetWindowBlock->context, clip, image); to  
draw to the window context.

image is a CGImageCreate using a CGDataProviderCreateDirectAccess  
which points to the squeak form, usually the Display.

With I think the right parms the CGBitmapContextCreate could write  
bits to a Squeak Surface.

I can't say how you would interface to Quartz Composer, first it  
would look like you need the Obj-C interface logic, then follow the
instruction on how to use the QCRenderer class to draw to an openGL  
context. Which at this point you have exhausted my knowledge of
how to continue.

Evil things, I note the  copybits logic grabs an extra word off the  
end of a form. That can cause a VM memory protection depending on
how the bitmap storage area was created. In Sophie we tried to use  
the Cairo png reader but found this copybits bug was an issue.
