Hello. I'm starting work on a new project, and would like to use Netbeans as the RCP framework. The problem is, our customer prefers a single document interface for our application, which Netbeans no longer officially supports. My question is, has anyone out there recently developed an SDI application using the Netbeans RCP framework, and if so, how did you re-enable or replace the now-missing SDI functionality?
Thanks,
Ed

I don't think it supports it specifically. Though have a look at these. Might help:

Support for it was removed a few releases ago, so it's not built in.
That said, it's possible to replace NetBeans' own Window System with
your own implementation that has the behavior you want. I wrote an
FAQ entry about it:

http://wiki.netbeans.org/DevFaqReplaceWindowSystem

The part about DummyWindowManager will probably be of special interest
to you since it opens each TopComponent in its own window.

Feel free to update the FAQ based on what you learn.

Tom, is there an @ServiceProvider annotation use that will do the same thing as
the #- prefix to remove the old one? Does the position value take care of this
if you know the other position value, or is there a way to make sure yours is
the one used if you use the annotation?

I'm just now switching to the 6.7.1 platform and so I haven't yet used
the annotations much. That said, the @ServiceProvider annotation's
javadoc:

http://bits.netbeans.org/dev/javadoc/org-openide-util/org/openide/util/lookup/ServiceProvider.html

indicates that you could set the position and/or specify a list of
implementations which your own implementation supersedes. If you
manage to get it working, it would be great if you could put a quick
example in this FAQ entry:

You can do either. Since the standard decl is (*)

package org.netbeans.core.windows;
@ServiceProvider(service=WindowManager.class)
public class WindowManagerImpl extends WindowManager {...}

and any declared position trumps no declared position, you could write

@ServiceProvider(service=WindowManager.class, position=/*RIPJSB*/1750)
public class MyWindowManager extends WindowManager {...}

to make yours be loaded preferentially (WM.getDefault just uses the first instance it finds); or

@ServiceProvider(service=WindowManager.class, supersedes="org.netbeans.core.windows.WindowManagerImpl")
public class MyWindowManager extends WindowManager {...}

to hide the original and thus have the same effect.

(*) You don't need source code or even binaries to find this out; just peek at the summary produced by dev builds:

Thanks for the quick help. I tried the annotation method, but I get a ClassCastException. I added the DummyWindowManager mentioned in the Wiki to the NetBeans Paint demo using the annotation:

Code:
@ServiceProvider(service=WindowManager.class, supersedes="org.netbeans.core.windows.WindowManagerImpl")
public final class DummyWindowManager extends WindowManager {
...
}


but when I run it, I get:

Code:

java.lang.ClassCastException: org.netbeans.paint.DummyWindowManager cannot be cast to org.netbeans.core.windows.WindowManagerImpl
   at org.netbeans.core.windows.WindowManagerImpl.getInstance(WindowManagerImpl.java:131)
   at org.netbeans.core.windows.PersistenceHandler.load(PersistenceHandler.java:141)
   at org.netbeans.core.windows.WindowSystemImpl.load(WindowSystemImpl.java:77)
[catch] at org.netbeans.core.NonGui$2.run(NonGui.java:184)


Since WindowManagerImpl is final, I don't see a way around this. Any ideas?
Thanks,
Ed
