Re: [ve-dev] How to extend VE in the following situation:

Max,
I'm sorry you haven't gotten a response yet. Here in the US, we've just
had our big Independance Day holiday and a lot of the core developers
have been on vacation. You're definitely asking in the right place.
I'll find someone who knows the answer to your question and can help.
In the meantime, I again apologize for our slowness in responding.
Best Regards,
Dave Orme
VEP Project Lead

Dear VE developers,
I've asked the question (see below) two times and unfortunately have no
any response. Probably this is not the right place for asking such
questions?
Please, give me any feedback. Where I should ask such questions? Or
give any
information source I could figure out answer from.
Sorry, if this is not the right place for such questions.
Thanks,
Maxim

*Subject:* [ve-dev] How to extend VE in the following situation:
Hi,
I'd like to change/extend VE to generate a slightly different code
in getter method
for a particular class. (SWING based)
**
*1. *In my application I have class:
**
class MyGenericAction extends javax.swing.AbstractAction {
public void setOwner(Jpanel owner) {
....
}
}
And I have different particular implementations of MyGenericAction
e.g:
class SendAction extends MyGenericAction {
}
**
*2. *I create JPanel in VE and put my SendAction into the panel
and set
properties Enabled and Name. VE generates the following code:
private sample.vep.SendAction getIvjActSend() {
if (ivjActSend == null) {
ivjActSend = new sample.vep.SendAction();
ivjActSend.setEnabled(true);
ivjActSend.setName("Hello");
}
return ivjActSend;
}
*3. *The issue is that I know that any MyGenericAction instance
always requires
also Owner property to be specified and the user can forget to
specify it explicitly.
So I need to override code generation for all classes extending
MyGenericAction
in the following way:
*1st option*
private sample.vep.SendAction getIvjActSend() {
if (ivjActSend == null) {
ivjActSend = new sample.vep.SendAction(*this*); *// The
"this" must be in the constructor for all *
*
//classes derived from MyGenericAction after I put
action to Panel*
ivjActSend.setEnabled(true);
ivjActSend.setName("Hello");
}
return ivjActSend;
}
**
*2nd option*
private sample.vep.SendAction getIvjActSend() {
if (ivjActSend == null) {
ivjActSend = new sample.vep.SendAction();
*ivjActSend.setOwner(this); // this code must be inserted
automatically *
* //for all
classes derived from MyGenericAction after I put action to Panel*
ivjActSend.setEnabled(true);
ivjActSend.setName("Hello");
}
return ivjActSend;
}
*Questions*
Could you please provide some recommendations for implementig such
or similar functionality?
Which extension points I need to implement to add the functionality?
Thanks in advance,
Maxim
