Avoiding the VM-Quit Dialog under Windows

Hi all,

I'd like to avoid/bypass the VM-quit dialog (Win32) by handling the quitting within the image. Is there any way to do this under the current Win32 VM? I know about disabling Alt-F4 and remember to have read some posts about a #windowClose event under Linux. Disabling Alt-F4 doesn't quite do the job for me, because the VM's close button is still visible to the user. So I'd like to be notified within the image if the user presses the X-button, and then have the image react accordingly.

Any help would be really appreciated!
-Jens

I *think* the latest Etoys version from squeakland.org does this, but
I do not use Windows so can't verify.

Re: [squeak-dev] Avoiding the VM-Quit Dialog under Windows

Thanks, Bert.

I just checked the latest Etoys version, and indeed found the code I was expecting in the image. Problem is, it doesn't ever get triggered under Windows. I tracked it back all the way down to the #primGetNextEvent: method in class EventSensor, and it just seems that a "type 5" (EventTypeWindow) event never gets signalled/polled. So, instead there's the VM-quit dialog again... :-(

I used the Etoys VM that was bundled with the download from SqueakLand (BTW, I had to rename the installer to *.exe, it didn't have a suffix to it, but then it worked beautifully and flawlessly).

Hey, that makes me remember: The Plopp VM apparently resolves the VM-quit dialog issue. Do you remember if you did anything special to it or is there some hidden aspect of the Win32 VM I'm unaware of?

Thanks!

Michael would know ... but I think the Plopp VM was not special. Maybe
have a look at Plopp.ini? But IIRC for Plopp we simply handled Alt-F4
in the image, I don't think it supported the close button.

Re: [squeak-dev] Avoiding the VM-Quit Dialog under Windows

You're right, Bert. Plopp just disables Alt-F4.

I just checked the WindowEvent code in Etoys with the latest Win32-VM I could find (3.10.7). That newest VM doesn't seem to be providing these events either. Is Windows that different from Mac or Linux? (Okay, that was a rhetorical question, sigh...)

if you use a current VM adding
EnableAltF4Quit=0

to the .ini does the trick. It controls both F4 and the window close
button behavior.

Hmm, which browser and windows version are you using? Just checked and
the installer downloads just fine including extension.

Yes, Michael, I already know that much. But this setting just *disables* Alt-F4 as well as the close button. It does not, however, notify my image of any VM-WindowEvents, or does it?

What I want to accomplish is this:

Whenever the user presses the VM's close button I want to be receiving some kind of #windowClose event, which my application can react to. I've seen all the necessary code in the new Etoys image, and I've read about these events in a post by Ian Piumarta (from last year, I think) in the Linux-VM. So, I guess my question is: Does the current (or newest) Win32-VM support these WindowEvents at all, because to me it doesn't seem so? (but it would be sooooo useful!)

I used Firefox 2.0.0.17 on an ancient WindowsME machine to download the installer, then I installed on my Vista computer

It should, but we just checked and it acutally doesn't. Need to
investigate further...

Thanks for looking into this, Michael! This would make Squeak applications so much more professional under Windows.

Er well people are welcome to update some of the documentation at

http://isqueak.org/ioGetNextEvent

to address the finer points of what getNextEvent tosses up, why
and how to turn features on/off

In reply to this post by Jens Mönig

Hi Jens -

I just finished uploading a new VM (3.10.8) which generates a window
close event when the EnableAltF4Quit preference is turned off. I've
tested it with the etoys4 image and it works as expected (for both the
close button as well as Alt-F4):

http://squeakvm.org/win32/release/SqueakVM-Win32-3.10.8-bin.zip
http://squeakvm.org/win32/settings.html

Cheers,
- Andreas

... and I just tested it with Scratch and it also works as expected. Thanks again!
