[Pharo-project] Handle Close Event in Image - necessary for 1.0?
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.

if you want this to be fixed for 1.1 open a ticket provide some tested code I cannot do everything especially for platform I do not have access to. Stef

a showstopper is something that breaks and put the system on its knees. So this problem may be fixed but only for 1.1.

Thanks Torsten for reporting. I don't think this is a stopper for 1.0 at all. We can release an older VM without that problem ? Even more because the new version 4 doesn't bring anything new for Pharo. isn't it ? The only problem where ImageSegment...Ok, I rather to have working this thing of closing the windows. Can you tell us exactly the link of the previous vm that was working ? because we are doing the one-click now and we took the 4. Then, for 1.1 open a ticket so that someone try to fix the problem with the version 4. Cheers Mariano On Tue, Apr 6, 2010 at 7:22 AM, Torsten Bergmann <astares@gmx.de> wrote:

This should pass, shouldn't it? [ FileStream newFileNamed: 'foo.txt' do: [ :file | file position: 1. self assert: file next isNil. self assert: file atEnd ] ] ensure: [ FileDirectory default deleteFileNamed: 'foo.txt' ifAbsent: [] ] Levente
