Hi,
I think I shouldn't create the store and the controller each time you click.
You just have to reload the store.
Something like this:
{"query": [{"json_id": "Puerto serie disponible", "fecha": "2012-01-22
13:40:40.836348", "editor": "JGenicio"}], "datos": [{"temperatura": 19.0625,
"TL": 23.1875, "TH": 25.0}], "puertos": [{"puerto": "/dev/ttyUSB0",
"dispositivo": "03a5b08768870d3f589cb7088699c989"}]}
The Selectbox:
var txt_config= new qx.ui.basic.Label( "Seleccionar
puerto");
var SeleccionPuerto= new qx.ui.form.SelectBox();
this.add( txt_config, { row: 1, column: 0});
this.add( SeleccionPuerto, { row: 1, column: 1});
The button:
var Boton_Scan_Puerto_Serie= new
qx.ui.form.Button("Recarga...", "aplicacion/22x22/actions/find.png");
Barra_Herramientas.add( Boton_Scan_Puerto_Serie);
var url =
qx.util.ResourceManager.getInstance().toUri(
"http://192.168.1.54:50000/cgi-bin/Domotica/Comunicaciones/RS-232/prueba.py";);
var almacen = new qx.data.store.Json( url);
var controller = new qx.data.controller.List(null,
SeleccionPuerto);
controller.setLabelPath("temperatura");
almacen.bind("model.datos", controller, "model");
Boton_Scan_Puerto_Serie.addListener( "execute",
function()
{
this.setStatus( "Actualiza
lectura de temperatura");
almacen.reload();
}, this);

Ana Sousa
