Anyone Ported the Nebula-PShelf-API to RAP [message #128850]

Hi,

Before I start doing such a thing I'd like to query here whether someone
has already done this and:

a) Published the code under EPL
b) If not published the code has some pointers what might be the best
strategy to make this happen

I'm currently investigating 2 different things:
a) Looking into the ExpandBar implementation and modify it to make it
work similar to an PShelf
b) Looking into Qooxdoo and their layouts the Grid-Layout goes into the
right direction [1]

I don't want to port the fancy drawing stuff - only the functionality!

I haven't worked with PShelf yet, but from the snippets and the
screenshot it looks much the same as the ExpandBar if one leaves
aside the appearance.
This would be my first attempt. The fact that PShelfItems apparently
can handle Composites should not matter on the client-side
implementation.
If a protoypish solution is sufficient, creating a custom widget
using composition could be even quicker.

Using client-side layouts do not work for Composites that layout
their children. The layout-information needs to be on the server-side.

Hi Rüdiger,

Thanks for your reply. I made good progress today using Composition
using ordinary Composites and GridLayout. I can live without the
animation stuff for now.

There's only one thing left for now. I need to set a background image to
mimic the gradient drawn by the original Nebula control everything else
works quite nicely.

Hi Tom,

glad to hear you succeeded. For scaling the gradient there is no
easy way to solve this in RAP as of now. Lets hope the default
images sizes don't change too fast;)
If you would like to maintain the code in the RAP repository, please
let us know. We a re currently in the process of creating an
incubator project [1].

Cheers,
Rüdiger

Hi Rüdiger,

I started experimenting with the GCCanvas but didn't finished yet but it
would give me the gradient.

I guess I won't be allowed to put this code into the public domain
because my company works as a contracter and the copyright is transfered
to our customer.
