Hi.
I want to, from script, extend a Java class that has no default
constructor. Specifically, I want to extend javax.swing.OverlayLayout
so that I can override some of its methods. I tried:
Rhino 1.7 release 3 PRERELEASE 2009 03 04
js> new JavaAdapter(javax.swing.OverlayLayout, { })
Exception in thread "main" java.lang.NoSuchMethodError:
javax.swing.OverlayLayout: method <init>()V not found
at adapter1.<init>(<adapter>)
...
so obviously I need a way to provide a constructor in my class so that I
can call super and provide an argument. Is there a way I can do this,
or will I have to extend OverlayLayout from Java?
Also, having the NoSuchMethodError quit the shell doesn't look good.
Maybe there can be a 'catch (NoSuchMethodError e)' at
src/org/mozilla/javascript/JavaAdapter.java:216 that throws some kind of
Exception.
Thanks,
Cameron
[PS: Actually, after I misposted this originally in m.d.t.js-engine, I
realised that I don't actually want to extend OverlayLayout; I need to
call setAlignmentX() on the components in the container. But extending
a class with no default constructor is something I've wanted to do
before, so the question still remains.]
