Thanks for responding so quickly and my apologies for not being clear.
I need to create a class inherited from qx.ui.form.List but when I do this:
qx.Class.define("timerecording.pruebas.lista",
{
extend : qx.ui.form.List,
construct : function()
{
},
members:
{
init: function()
{
Tad= [{ 'calle': 'Sin datos'}];
modelo= qx.data.marshal.Json.createModel( Tad);
controlador = new qx.data.controller.List( modelo, this,
'calle');
}
},
events:
{
"completed": "qx.event.type.Event",
"leftClick": "qx.event.type.Event"
}
});//Fin objeto
I get this error.
TypeError : container is null
my question is, is it possible to create a new widget starting from
qx.ui.form.List and give more features.?
My idea is to create a widget that contains routines to query the database,
you can distinguish between several tables for which data is displayed
correctly and the time to create the forms code does not involve a lot of
typing but is creating a nothing new variable of the form "var list = new
list (tabla_x);"
Best Regards
