hi all,
the Developer's Guide link is dead, http://eclipse.org/rap/developers-guide/devguide.php?topic=advanced/custom-widget.html#native

any samples or doc for creating the native custom widgets without JSWriter with RAP 2.0?

Hi.

For RAP 2.0 there are going to be many changes that break existing
native custom widgets. Since we are still in the middle implementing
these changes, there is currently no point in writing a guide for custom
widget development on RAP 2.0. There will definitely be a guide, but i
can't say when, except that it should be before the 2.0 release.

Greetings,
Tim

Thanks to Buschtoens.
Hope to have a simple document or tutorial, I intend to develop my new project on RAP 2.0, and now I do not know how to start with custom widget and old custom widget can not work on RAP 2.0 any more.

Is there a developer's guide for migrating (developing) custom widgets to the new RAP 2.0 world yet?

The release notes of RAP 2.0 M1, M2, ... RC2 just mention it (but didn't explain) and in RAP wiki (http://wiki.eclipse.org/RAP/Custom_Widgets) the section regarding RAP 2.x is still empty...

Custom widget development has become a lot easier with the new Remote
API [1]. Unfortunately, we didn't manage to write a guide yet. However,
there are some examples to learn from. I'd recommend to have a look at
the CKEditor widget [2], which uses the new API and is up to date with
2.0. API documentation is also available: [3] for the Java Remote API
and [4] for JavaScript API.

Let us know how if you notice any problems. Your input will help us
creating a custom widget guide.

Regards,
Ralf

Hi Ralf,

thx for your quick response and the links provided.

I just started migrating a non-GUI widget based on the links you provided. Communication between server and client side is working fine (using pure JSON now). Notifications (triggered on client side) are working as well.

Using the LCA approach for implementing custom widgets isn't recommend by the release notes of RAP 2.0. Nonetheless RAP 2.0 still uses LCAs for its widgets. Why? Is using the LCA approach still a way for migrating my custom widgets? Or shall I eliminate all LCA usage?

How do I migrate custom widgets based on qooxdoo? Where do I have to place my code handling things like "rap.registerTypeHandler('myCustomWidget')" and the like? In the qooxdoo-constructor of my widget?

Any suggestions are welcome Smile

That's good to hear :)

Because it's a whole lot of work to change that. Anyway, the widget LCAs
will be changed to use the Remote API as well. We're looking forward to
replace the concept of lifecycle phases in favor of the remote API in
some future version.

LCAs are still supported but discouraged for new widgets. At some point
in time, we'll have to discontinue support for LCAs.

You probably know that RAP maintains a modified subset of qooxdoo. The
classes have moved to the rwt namespace. However, you can use these
classes at your own risk.

The typehandler has to be registered only once, directly in the code
that defines the widget. In the factory function, you'd create an
instance of your widget.

Regards, Ralf
