Where is the jContentPane? [message #75365]

I installed VE, but I couldn't get any GUI to work. Where is the
jContentPane in the Beans View? My visual class extends JFrame. Now, in
the Beans view, I am supposed to see the jContentPane, so that I can drop
swing elements on it, right? Something like Figure 3 in this IBM tutorial?
http://www-106.ibm.com/developerworks/opensource/library/os- ecvisual/

But nothing. The Beans view is empty. I can drag swing elements there
directly, but they are not in the ContentPane, and thus are not shown when
I start the app. Just an empty JFrame is shown.

What's wrong?

Thanks! Andi

P.S.: I use Eclipse 3.0.1, VE 1.0.1, GEF 3.0.1, EMF 2.0.1

What steps are you using to create the visual class?

Since the time I wrote the article you reference, the new visual class
dialog box has changed: instead of entering the superclass directly (or
using the browse button) you should choose Swing/frame in the Style
selection box on the left side of the dialog. If you bypass this way of
selecting the superclass, it seems that the jContentPane doesn't get
generated.

Thanks for your answer. I did exaclty what you described. It must be a
bug, or some plugin versions did not match. It was under Win XP. Now I
tried the same under SuSE Linux with Eclise 3.1M1, and everything worked
fine and easy here.

Strange! I tried it on yet another system, and it does NOT work. It's
RedHat Linux (gtk) with Eclipse 3.0RC2, VE 1.0.1, GEF 3.0.1, EMF 2.0.1.
Same results as in my first posting (see below): No jContentPane, no image
of the application in the upper part of the window.

Does VE only work with Eclipse 3.1 maybe?

I checked on the prerequisites: VE 1.0.1.1 requires Eclipse 3.0.1, EMF
2.0.1 and GEF 3.0.1. So that might explain why it doesn't work on your
Red Hat system, but not why it doesn't work on your XP system. I'm
using the same thing on my system & don't see the same problem.

What version of Java are you using? I think the latest 1.4 (1.4.2) is
recommended, but while 1.5 supposedly works it is not officially supported.

I'm running Windows XP and Java 1.4.2 with
VE 1.0.1.1, Eclipse 3.0.1, EMF 2.0.1 and GEF 3.0.1.

When I check Eclipse's error log just after attempting to visually
edit my JFrame extended class, I see an error report which I have
pasted below.

Your problem here is that you probably have EMF Examples installed. As
of 1.0.1.1 VE and EMF examples are incompatible. This has been fixed
with VE 1.0.2

Thank you. You were absolutely right. Once I loaded
VE 1.0.2 the problem was solved.

Strange! I tried it on yet another system, and it does NOT work. It's
RedHat Linux (gtk) with Eclipse 3.0RC2, VE 1.0.1, GEF 3.0.1, EMF 2.0.1.
Same results as in my first posting (see below): No jContentPane, no image

Does VE only work with Eclipse 3.1 maybe?
