1. So this means that, when I
drop a ULCLabel from the palette on the canvas, there is no way to generate:
 
private ULCLabel ulcLabel = null;
 // declaration for global 
 
 
ULCLabel getUlcLabel() {
    if (ulcLabel ==
null) {
      ulcLabel
= ComponentFactory.createLabel();
    }
    return ulcLabel;
}
 
>  The ConstructorDecoderHelper will generate
what ever the javaInstance.getAllocation() is.  it is up to the commands
to set the proper ParseTree
 
-----------------
 
2. Moreover, we have a class ULCFiller.
When a filler dropped from the palette into a container say ULCBoxPane
on canvas, I would like to generate
 
       box.add(ULCFiller.createHorizontalStrut(150));

>  ha... A different decoder is used
here..  I beleive that at this time, it will only deal with a new
FooBar()... 
> This is support we need to add (please
open a defect)... for now you will have to create your own decoder.

3. Then there is Separator.
 
When I drop a separator from palette
on a Menu or ToolBar on the canvas, I would like to generate:
 
    menu.addSeparator();

> This is a method invocation... which
is on the queue for us to support :-(

Is it possible to generate this
kind of code?

ugly harcoded way could be (and I am embarrased to say this out loud :-(

and create the propert decoder/proxy for it.

4. In general how does one:
 
1. Customize code gen for a bean
instantiation
> The only support is via the
Constructor, and the GLOBAL/LOCAL mechanism.

2. Suppress generation of instance
/ local var for a bean
> We are working now on implicit beans
(like a ContentPane for a JFrame).... but it will go into 1.2

Thanks and regards,

At this time VE will only deal with a static assignments, e.g.,  ULCLabel
l = ComponentFactory.createLabel(), where createLabel() is a static method.
 This is since the Parse Tree can be evaluated, as is, on the target
VM. 

We plan to add generic method invocation with https://bugs.eclipse.org/bugs/show_bug.cgi?id=49432

Subject	[ve-dev] Are factory methods supported by Visual Editor?

Hello,

Is it possible to specify factory methods instead of 
constructors for the code generation part of VE?

I.e. what I want to get generated is the following:
   ComponentFactory.createLabel()
instead of
   new ULCLabel()

Thanks and regards,

Janak
