DESCRIPTION:
This Application is used to create a GUI inside a wave
gadget from a JSON passed via the wave API (wave.getState()). This
Application expects the JSON data to construct the menu
from in wave.getState('ui.structure') with a special structure we call
the qooxwave protocol. This protocol is not yet completed.
For understanding qooxwave protocol, have a look at the documentation:
https://2009.igem.org/Team:Freiburg_software/Project/qooxWave-details
TODO:
- complete qooxwave protocol
- gadget resizing should respect menus
- Refreshing UI on every state update is not neccessary
- solve absolute url problem (still pointing to sourceforge.net in config.josn)
- rebuild the model on user input and bind model to store
- MVC improvement: when changing something like clicking on a checkbox, the model is not updated correctly
therefore the state has still the old value (no checkbox clicked),
nothing will happen, eventhough the server might whant to uncheck the checkbox!
So there must be either
- a update of the model
- allways update gui on stateupdate
- some kind of mixing of the above: not on every state update, but if the model
might be out of sync
- modelling is very sensible cerncerning their ids. they cannot contain certain characters, which?
- check target url for upload widget
