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:
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;
}
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
