Hello,
as you know I would like to implement a relationship between components
that is a little bit like a relationship between a Shell and SWT Button.
In my case there is a variable:
Hashmap hm;
in the code. And if I drop a swing button on the frame a button with a
parameter hm has to be instantiated.
myButton = new MyButton(hm);
Hashmap for my button has to be like parentComposite (Shell) for SWT
button.
(1)
Do I have to develop an editpart and an editpoliy beside decoderhelper to
reach my aim ? Or do I have to implement other classes? I have already
seen how to define an editpart and an editpoliy in override files.
I know I asked you a lot about instantiating a component with a parameter.
I really appreciate that you always gave me a detailed answer.
(2)
Could you give me an estimation how complex it is to implement my case or
how long it would take? It must also be considered that I am new in this
theme.
Thank you in advance
Elena

Hello,
could you give me a hint what classes and interfaces I must implement and
where it is better to start?
Thank you

Hi Elena,

What is the hierarchy of your classes. You said none of them were
visual but then you talked about Swing. Is your example something like
A extends Object{
public B getB();
public void setB(B);
B extends Object{
public void addA(A);
public void removeA(A);
}
What is the example of a full class .java code that contains a
relationship between parent and child you want the VE to be able to open
with ?
Best regards,
Joe

Hello :o),
in my case the relationship is like this:
-------------------------------------------
Public class B extends JButton {
Public B (A a) {
a.setB(this);
}
}
-------------------------------------------
Public class A extends Hashtable {
putB(B b) {
}
}
---------------------------------------------
As you see the class B is a visual class and the class A is a not visual
class. The Class A has a list of Objects of the class B. I hope it is
possible to implement my example.
Thank you very much :-)
Elena
