Hello folks,
I try to improve my webui which already use qooxdoo.
My webui is above an embedded system and it is used to change the config
and display status.
For now, I get back the different config sets and status in json with a
RPC call, do a JSON.parse() and manually, for each form and page, I set
the different values needed.
Lot of code, so I want to improve it.
I want to use the power of model, view and controller using
qx.data.controller.Form class.
I did some try, created a static model represented a part of the user
config, set it to the form controller. My form is fill by the model.
--------------------------------
var data_obj = {
trigger: {
enabled: true,
pre: "3",
post: "4",
mode: "Level",
maxlen: "300",
chan: "XYZ",
logic: "OR",
level: {
x: "10",
y: "10",
z: "10"
}
}
};
var data_model = qx.data.marshal.Json.createModel(data_obj);
this.__data_form_controller = new qx.data.controller.Form(data_model,
this.__ui_form, true);
--------------------------------
But now, I've some concerned about how organize all the stuff.
Especially, the part where I send back the modification done by the user
by a RPC call.
I followed the feedreader example. I created my models (under
mystuff.model.*), a rpc loader (under mystuff.io) and views (under
mystuff.view.*). I began to write each page in a singleton class.
* How can I write the apply code for each form ? Here the code I did
for my apply button for now :
--------------------------------
ui_button_apply.addListener("execute", function() {
if (this.__ui_form.validate()) {
var model;
model = this.__data_form_controller.getModel();
}
});
--------------------------------
I don't want to send all the config each time the user modify the
config. Do I need to create an object with the config and do a JSON
stringify like this ?
--------------------------------
var trigger_model = model.getTrigger();
var data = {
trigger : {
enabled : trigger.getEnabled(),
pre : trigger.getPre(),
/* ....*/
}
};
var text = JSON.stringify(data);
--------------------------------
Furthermore, I don't want to write in each page the rpc call and analyze
the call answer. So, how can I organize the code ?
* Second question. How can I give the model to the page ? Is there a
good way to do that ?
* Third question. How can I update the model ? As you can see above,
when I instanciate a qx.data.controller.Form, I tell him I want to be in
charge of calling updateModel() to update the model with the new values.
I guess I have to add the call when the apply call is a success, right ?
But, I need another way to update the model. For example, if the user
stay on the webui a long time and come back, perhaps the model is
outdated because some other user on another computer has modified the
config. I think about a cache timeout. The model will be valid for XX
seconds. So, when the user come back, go to another page, I force a new
RPC call. What do you think about this system ? Is there an example of
this elsewhere on the internet ?

Viallard Anthony.
