Hi, I'm new to VE and the Java platform and am having trouble getting my
frame (with panel and button) to display when I run a simple Java App
project. No clue! Main executes, but no UI components seem to execute.
I tried putting a method breakpoint on "private JFrame getJFrame()" but the
debugger ignores it, so I don't know if I'm asking the debugger to do
something it can't do, or if there's a code problem of some type.
Shouldn't the JFrame and components just display or am I missing some
configuration issue?
Versions:
jdk1.4.2
eclipse 3.0.1
jre1.4.1_03

Hi Paul,
Did you write any code within your main() method to call the getJFrame()
method? The VE doesn't write the main() method for you when working
with Swing because usually there's more to starting up an application
than simply opening the JFrame. Using Run As->Java Bean we allow you to
test out your visual classes without having to write a main() method.

Jeff,
No, I only tried a static call to getJFrame() and it predictably (I'm now
realizing why) complained about the method not being static. So that's my
problem. I have to now catch up with how you guys do this because I'm not
used to instantiating an instance of a class that I'm already in order to
run its private methods. I shoulda known when I saw the compiler error.
This is obviously not a VE or IDE problem, so thanks for steering me in the
right direction. Paul
