The universe entry loads the package from my server not from squeakmap.

This only would make sense if Ramon's image would have a cached squeak-
map with Glorp version 0.4.129. Every other combination IMHO can't
work.

Hmmm, I changed the url in the package to point to a proper destination.
I did a fresh install of a 3.9 image. I opened squeakmap and reloaded
the map. The map reflects my change I've done two hours ago. But the
install action seems to try to load from the old URL which still leads
to the login form. The URL which is now in the map is correct but the
install fails. I'll monitor this.

Hi all,

I am fairly new to Squeak, and so far I have figured out the syntax 
and everything, I do understand the basics. However, I am stuck on one  
particular thing - manipulation of objects that have been created, and  
are now in a World. I think the easiest example of what I mean is by 
the following. Assume for a moment I have created a simple 
RectangleMorph in the World, in this case with a specific parameter, 
the color. The code for this would work out as:

| rectangle |
rectangle := RectangleMorph new openInWorld.
rectangle color: Color white.

Now, that the object is created in the World, how do I change its 
properties while it exists? How would one change the color of the 
RectangleMorph in this example, while it is on screen? Since 
everything is an object, and objects can receive messages, I do 
believe this to be possible, correct?


Thanks for your help,

Marcus

Just send messages to your reference (rectangle).

You did this in line 2

rectangle color: Color white.

You can send other messages like

rectangle useRoundedCorners.

If you dont have a reference to your morph, open a workspace, select 
in its menu

"create textual references to dropped morphs"

then drag and drop your morph into your workspace. Use the printed 
reference to send messages to.

Hope this helps
Enno

ya, an inspector works, you can also use the halo to change some things in
morphic

And to get the inspector (if you didn't know), you can start with the
red menu halo, go to debug, and then choose inspect morph.

I can't seem to resize Omnibrowser columns, is it something subtle?

yes, exactly. It's also a fixed bug, you can get the fix by downloading the newest
version of the OB-Enhancement package from Colin's Monticello repository at
http://source.wiresong.ca/ob/.
