[vwnc] Closing a window and opening a Dialog ...

Dennis smith-4
The normal "ApplicationModel" close is asynchronous, and if you do the
following

    |app|
    app := XXcityUI allInstances detect: [:x | x builder window isOpen].
    app closeRequest.
    Dialog warn: 'Testing'

Where there is an open window of XXcityUI, a subclass of
ApplicationModel, then it does
not close because the Dialog opened before the close occurred, and the
close says if there is
a modal window open, do nothing.

I can see a few ways around this -- but I am interested in how others
close their windows and if
anyone has seen this problem before??

Re: [vwnc] Closing a window and opening a Dialog ...

thomas.hawker

That raises a question I’ve had for some time.  Why is a synchronous attempt to close a window deferred and made asynchronous?  I can see that the asynchronous path is required because of incoming [external] window events, such as those passed up from the host window manager.  But it seems to me that if, under normal application control, I close the window, it should go away immediately.  That is, it should just do all the things that normally happen without deferring the behavior to the window manager event loop.

 

Cheers!

I suspect the reason it does not allow a window to be
closed if a dialog is open is because you don't want the
dialog's parent to close. I suppose the test could be made
more specific to not allow a window in the modal chain
to be closed.

If you know the window you are closing is not in the modal
chain can always duplicate most of the code in
ApplicationStandardSystemController>>closeNoTerminate and
bypass the test.

Re: [vwnc] Closing a window and opening a Dialog ...

Dennis smith-4
Yes that was my #1 solution -- I actually have a
    closeImmediate
method that does that -- I was just interested in comments -- thanks
