Whoops. Accidentally sent to the wrong list :-) - A. -------- Original Message -------- Subject: Re: Handle Close Event in Image - necessary for 1.0? Date: Thu, 15 Apr 2010 15:56:59 -0700 From: Andreas Raab <andreas.raab@gmx.de> To: The general-purpose Squeak developers list <squeak-dev@lists.squeakfoundation.org> Hi - Just as a reminder when you discuss VM stuff, make it a habit to include vm-dev@lists.squeakfoundation.org. I don't read the Pharo list regularly (I only checked it today due to the unfortunate Scratch development). This whole issue was entirely unnecessary and could've been solved with one message to vm-dev. Here is why: The in-image close-event that is now generated by default in the Windows VM has always been a settable entity. If you'll compare the 4.0.2 vs. 3.11.8 VMs the only difference in this area is that the preference "EnableAltF4Quit" is now unset by default. To change it, edit your .ini file to have: EnableAltF4Quit = 1 and you will be back to the previous behavior. You can add this trivially to your one-click (or other) setup. In fact, I'd recommend going carefully through the other relevant vm settings and decide how they should be set for your releases. They are documented here: http://squeakvm.org/win32/settings.html So next time, do include vm-dev when you have a vm issue.

I think I've found something that should be fixed before releasing 1.0 since it is meanwhile a major problem on Windows.

In "old" Squeak/Pharo you could close the native world window using the "X" or hit ALT+F4 on Windows and the system asked you if you really want to close the whole Smalltalk system using a native dialog which was provided by the VM.

With the new VM's (4.0.1 and 4.0.2 on Windows, see [1]) the native "window close event" is now dispatched from the VM into the image so it could be handled by Smalltalk code. This is currently not done/handled in Pharo. Only in Squeak so far.

The recent Squeak trunk/release candidate already handles the event within the image and now provides an in-image dialog to ask the user to quit.

So: in Pharo now NOTHING happens when you try to close the window using "X", you can only quit using the world menu - which is IMHO really a show stopper since you cant close using "X" or ALT+F4 (the key combination to close any windows program).

Two possible options:

A) we should handle the event now in-image similar to Squeak by fixing and integration issue 2131 (see [2]), so not only for 1.1. but also for 1.0

B) release and distribute Pharo 1.0 with an old VM< 4.0

BTW: You can get the old behavior on Windows by additionally using SHIFT, so SHIFT + ALT + F4 allows to close. But this is not very convinient, doesnt follow what the typical Windows user expects and one has to know about it...

Bye T.
