<p>Hi Marcel,</p>
<p><br>
</p>
<p>these are reasonable follow-ups, though I think they would be part of another big project, decoupling various packages in Squeak and cleaning up their dependencies.</p>
<p><br>
</p>
<p>However, your list looks like a good guide for developers that do not know the differences between these variants. Shall we copy your text somewhere into the wiki?</p>
<p><br>

<p>Best,</p>
<p>Christoph</p>

<div class="PlainText">Hi Christoph.<br>
<br>
It's all in Trunk now. ;-) Here are possible next steps:<br>
<br>
1. "Project current world" vs. "self currentWorld"<br>
<br>
In all packages that should not be dependent from Morphic, use "Project<br>
current world". Otherwise, use "self currentWorld".<br>
<br>
2. "self currentWorld" vs. "self world"<br>
<br>
In morphs, try to use "self world" whenever possible. Only class-side<br>
methods should use "self currentWorld". Well, if you have code that should<br>
work with morphs not being installed in any world, use "self currentWorld"<br>
because it will fall back to "Project current world".<br>
<br>
3. "self currentHand" in non-Morphic packages (ST80, Tools, etc.)<br>
<br>
Well, there are some cases where the use of "self currentHand" adds a<br>
dependency to the Morphic package. Not sure whether we can fix this now or<br>
whether we want to extract object-oriented event handling out of Morphic<br>
first to be used in other graphics frameworks such as ST80, SqueakShell,<br>
etc. :-)<br>

Marcel<br>
