Thanks Alex for the example. Nice code! I see there that the main frame is generated within the execute method, an approach that I was taking, but was not sure about.
Since I know my own agenda, I recommend that you use the Startable interface instead... I think there will be consensus to remove Executable
in Framework 5.0, since the Startable can do the same job.
I think this subject will raise a bit of debate. Startable is a non-blocking operation whereas Executable is in-line execution. As such, you can correlated Initializable and Executable much more closely that Executable and Startable.
I think in the execute/start method the main frame is build and shown. But I
think a separation of roles would be good in terms of being responsible for
- an initial setup, coordination of managers and start of the whole application
- a GUI - the main frame (see thread "Merlin for Applications")
Both might implement Initializable, Startable and/or Executable. So which one is now the right one for what exactly?
Based on what you said above - your describing a service interface equivalent to Executable. In effect - the framework Executable interface and the semantics it implies on the container/component contract do not allow for the separation of the concerns you describing - however, if you put in place your own Executable and published this as a service that your component provides then you can take control over this.
Actually this is exactly what I did in the last GUI app I built.
Cheers, Stephen.
