Initializing gadget state from robot

[Chris Searle]

If you have a robot add a gadget to a wave (adding a document.Gadget
to the blip document) - is there a way to initialize the state of the
gadget? For example - if the robot has found enough information in the
blip text itself - it would be nice to just use it instead of
presenting the user with the form that is used when no state is present.

You need to get the Gadget entry from the gadget you added. Once you
do this, you can use element.setField(key, value) to control its
state. I'm not sure how to go about getting the gadget object for a
newly added gadget (gadget insert/append have no return types).
Perhaps you can go back and try something like GadgetView.getGadgets
or getGadget("url") to find it again.

Chris,

In the java api gadget.setField(key, value) does the trick. You can
then read the field with wave.State().get(key) in the gadget.

see http://wave-robot-java-client.googlecode.com/svn/trunk/doc/com/google/wave/api/Gadget.html
and http://code.google.com/apis/wave/extensions/gadgets/reference.html

Ah. Looks interesting. This would allow me to replace my python code
with a static XML file (would have to move the code - a urlfetch that
retrieves json - to the gadget - but that's not too hard).

I'll look into this.

Here's what I'm doing:

gadget = document.Gadget(gadgetUrl)
doc.InsertElement(m.start(0), gadget)

Now - from http://wave-robot-python-client.googlecode.com/svn/trunk/pydocs/waveapi.document.Gadget-class.html
I wonder - can I not just call:

gadget.SubmitDelta()

after adding it to the doc? Not that I can see what format it should
be in yet ;)
