Hi,
sending and subscribing to messages works similar to dispatching and
listening for events. So if you have a button mybutton, you write
qx.event.message.Bus.subscribe("activation-message",function(message){
this.setEnabled(message.getData());
}, mybutton);
and within the field that should activate the button, you write, for example
myfield.addEventListener("focus",function(){
qx.event.message.Bus.dispatch(new
qx.event.message.Message("activation-message", true))
});
I will write a tutorial on messagens soon.
