[e4-dev] Model changes for 4.4 M4

[Paul Elder <pelder@xxxxxxxxxx>]

Eric Moffatt  and I are planning a
number of E4 model changes for next week (M4). Our initial cut is below:

* Change MCompositePart to extend MGenericTile<MPartSashContainerElement>
rather than MPartSashContainer. (This is so that MCompositePart will extend
only one concrete type, namely MPart. In implementing split editors/views,
Eric found that the MPart/MPartSashContainer ambiguity caused some problems.)
* Deprecate MInputPart and MInput.
     * Question: Is there
need for an 'inputSpec' attribute on MPart? (A replacement for MInput's
inputURI attribute.)
* Create MWizard and MDialog classes
(that extend MWindow), and add corresponding collection attributes on MApplication
     * Question
          *
Is there need for new attributes on these classes?
          *
Is there need for MWizardPage, too? (It seems to me that MWizard's 'children'
being mapped to the wizard's pages is sufficient.)


Feedback is appreciated. In an effort
to keep this discussion grounded, please support any suggested additions/changes
with some form of code example that demonstrates why the change is necessary.
