<p> Have you ever tried MorphicWrappers (I'm feeling
like I'm going to make
<br>everybody skip my messages if I keep talking about MWs... sorry)
<p> One of the nicest things about morphic wrapper is
that you can evaluate a expression
<br>just by typing it (anywhere) and pressing enter.
<br> We call it typing in the air, it's like this:
<br> When you start typing, a
balloon pops up (attached to the HandMorph) and starts
<br>containing what you are typing [you are editing balloon's contents],
when you press enter
<br>the expression gets evaluated and the result gets attached to the HandMorph
(arrow).
<br> For example, if you point to the background of a
World (the World itself) and write
<br>EllipseMorph new, a new EllipseMorph gets attached to you hand... But,
eh! what happens
<br>if I type something like '1+2', where the result is not a Morph? well,
you'll get a MorphicWrapper
<br>on the result, that will wrap the result, and show it in a Morphic
way...
<br> And also, the current context for what you are typing
is the object under the arrow, so, if you
<br>are pointing to the just created EllipseMorph and say: 'self color:
Color red', ellipse's color will
<br>change to be red, and if you say bounds, you'll get EllipseMorph's
bounds.
<br> If you drop a block on the World (just type '[1+2]',
and press enter, for example), you place
<br>it in the world, place the arrow over it, and say 'self value', you'll
get '3' attached to your hand...
<br> Ok, there's more of it... just ask, I'll gladly
answer!
<p> Answering Bye!
