Hi all,
VE is working fine for me when I create a new visual element (eg. JButton)
through the VE engine. But when I tried to visualise a JFrame and its
contents that I had written "by hand" before I get a blank screen even
though I had opened the class with the "Visual Editor". (When I run the
class everything is fine!)
Am I doing something wrong? My own code is of course different from code
generated by the VE - but is this the reason that my code is not
visualised?
Regards,
Georg
Here is the code, some of it is in German but don't bother...

Hi Georg,

What occurs when the VE opens is that it parses the code to look for patterns and from
this it constructs a model of the Java components, their properties and relationships, and
this is what drives the GUI, tree, property sheet, etc... There is an article that
describes these patterns at
http://www-106.ibm.com/developerworks/websphere/library/tech articles/0303_winchester/winchester.html,
although this was written in February and there have been enhancements made since.
However the basic concepts in the article should still hold true.
Looking at your code there were a few changes required to make it VE parseable.
1 - Initialization should not occur during the constructor as you did. Instead we
look for a specific method that by default is initialize() although you can add new ones
using the Visual Editor preferences.
2 - The contentPane should be explicitly defined in its own field. We don't support
an implicit content pane right now as you coded.
3 - Every Java component needs its own field. We do have a line item to support the
kind of coding pattern you have where fields are just defined locally in methods as this
is a common coding pattern, especially for JLabel and other literals.
4 - For the JSpinner you referenced the static private field MAXRECHENTIEFE in their
construction. Right now we don't support this, although if this were on a separate class
as a static public field we would, i.e. if it is something we can find from reflection on
another type.
I re-wrote your class as below and this seems to parse and open OK in the VE.
Patterns for code parsing is one of the line items that needs to be worked on for a future
release, because the goal of the VE is that it is more flexible with the type of code it
can consume.
Best regards,
Joe
