Updating a jpanel

Another time saver and a great way to explore the APIs.

I guess most people knows about this one but maybe not all the features.

Usually I’m writing about Net Beans RCP applications but this time it will be about Net Beans as an IDE.

Using raw sockets wouldn’t allow for the delegate callbacks (people subscribed to the Mediator class’ Message Received event). Hence here the collaboration pattern is that each participant (here the buttons) communicates to the mediator its activity and the mediator dispatches the expected behavior to the other participants.It is aware of all of the Colleagues and their purposes with regards to inter-communication.Colleague - defines the interface for communication with other Colleagues Concrete Colleague - implements the Colleague interface and communicates with other Colleagues through its Mediator The Mediator pattern ensures that components are loosely coupled, such that they don't call each other explicitly, but instead do so through calls to a mediator.And to show the methods available on an object just hit ctrl space after the dot and those will be shown with the javadoc.So this is something most people knows about and use ctrl space for.. If you for example adds a new variable in a constructor just enter the type and ctrl space and Net Beans will show a few example of the variable name that you can use. If you place the cursor outside a method body and hit ctrl space it will show a list of available methods that can be overridden if you class is extending another class for example.In the following example, the Mediator registers all Components and then calls their Set State methods.
