I have a large flex application (the app) running on one server, and many small flex applications (widgets) running on another server, which are to be included in the app so that visually the user see's one continuous application. Due to proprietary third party software, this structure cannot be changed. I am looking for some way to al...
Very typically I have a situation where a given object will need to have many listeners. For instance, I might have class Elephant { public void addListener( ElephantListener listener ) { ... } } but I'll have many such situations. That is, I'll also have a Tiger object that'll have TigerListeners. Now, TigerListeners and Elephan...
Hello - I am trying to send an event to iframes which have been opened by the application based on few events which should be prior registered by iframes. I cannot figure out how. I use jquery but I don't expect the iframes to be nice citizens to implement listeners in jQuery. Though I can mandate it - I am still looking for normal java...

Or does Java need to revert back to some sort...
I have implemented the event listener pattern in PHP, and setup a test case to validate that it is working within a single call to a URL. I'd like to be able to persist this state between calls while avoiding setup/teardown of all of the events within the application. I'm hoping that by persisting the state, when an event is fired, the ...
I would like to use factory classes and methods to generate GUI components, but I don't know how and in which class the various listeners should be declared and added to the components. If I have a simple factory class such as that listed below should I add an ActionListener to the button before it is returned to the calling class. If t...
For example, say the main Activity has an custom object foo with a method called bar. When foo.bar() is called via the activity, it does a bunch of things on a thread and when it is finished it would somehow alert the main ui thread, the activity, it's parent that it is finished. I imagine this working the same way an event like a On...
I have code similar to the following: public class myButton extends JButton() { public int data; public myButton(){ super("asdf"); data = 2; } } public class myPanel extends MouseListener() { myButton myButtonVar1; myButton myButtonVar2; public myPanel() { myButtonVar1 = new myButton(...
