Hi Again,
The call to the backend is asyncrounous, your
qxgui.utils.Rpc.callAsync() function will return immediately.
There are two ways forward, you can either change your class so it fires
an "complete" event, or change the function so it accepts a callback.
From the callAsync() function it looks like you are expierenced enough
to do either without help.
The two choices would make your calling code look like this:
Option 1.)
var rpc = new qxgui.utils.Rpc;
rpc.callAsync( "doLogin", [ username, userpw ] );
rpc.addListener("complete", function(e)
{
var result = e.getData();
});
Option 2.)
var rpc = new qxgui.utils.Rpc;
rpc.callAsync( "doLogin", [ username, userpw ], function(result)
{
alert(result);
});
If you need more help, just decide first which one best meets your
requirements and let us know :)
HTH,
Matt
