Hi!
In the PharoTaskForces SqueakSource repository I committed a new
version of Morphic (Morphic-Alexandre_Bergel.393). This version
includes the window announcement I have been working on for few months
already.
Here is an example of a unit test.
-=-=-=-=-=-=-=-=-=-=-=-=
MorphicWindowNotificationTest>>testWindowCreationAndDeletion
| t window newWindowCreated r |
t := 0.
World announcer on: MorphicCreationWindowAnnouncement do: [:ann |
t := t + 1. newWindowCreated := ann window].
World announcer on: MorphicClosingWindowAnnouncement do: [:ann | t :=
t + 10. newWindowCreated := ann window].
window := SystemWindow labelled: 'foo'.
window openInWorld.
self assert: (t = 1).
self assert: (window == newWindowCreated).
window delete.
self assert: (t = 11).
self assert: (window == newWindowCreated).

If everybody agrees on this, it would be cool to include it in Pharo
soon. At each new version of Morphic, I will have to update this, and
this is boring.
The comment of the .mcz is
-=-=-=-=-=-=-=-=-=-=-=-=
This new version extends Morphic with a window event mechanism.
It add a variables to SystemWindow (thus implies a recompilation of
all subclasses of SystemWindow).
It does some overrides in:
- SystemWindow: for deletion, resize, ...
- ScrollPane: notification for scrolling. This part is probably not
nicely designed, but it works
- PasteUpMorph: World can now emit event for window creation and
deletion
The method SystemWindow>>openAsIsIn: is overriden. The new version
belongs to Morphic, before it belonged to Polymorph. Loading this
version make Polymorph dirty therefore.
5 test methods are provided in MorphicWindowNotificationTest. All
tests are green in a pharo1.0-10502-rc1dev09.12.2

Comments are welcome
Cheers,
Alexandre
