In my HelloWorld console-based tool, I want to over-ride the "open" request so that the console displays a custom message when the session starts, for example:
Hello World Console
Today's date is 10/05/2009
open project://my_project/session_profiles/hw.ffsp
Welcome!
Hello World>
I am trying to insert the lines in bold above; what class do I over-ride to accomplish this?
There is no "overriding" needed to do this. The controller is a "view", anything it displays needs to go through the model. In this case the easiest thing is to have your open handler just put the text it wants in its response. This will then be shown by the view and it will show up in the test report.
If you want to have other means of displaying stuff in the view, you will need to customize the model to allow the controller to provide/set this information so the view can retrieve it.
Again, you aren't overriding anything, and your handlers are not directly writing to the console. The importance of this last part cannot be overstated. The controller and model cannot know anything about the view. they need to function without views and they need to be able to use any view that is attached to them.
I may have missed something in the documentation - The Hello World walk through does not create any handlers for "open". If I were to create my own OpenHandler and attach it to the "open" request, the console does not open.
Are you setting open correctly in the open handler
From SessionController jdocs:
It is very important to handle open properly. If you have NO IRequestHandler defined for open, the controller will automatically open the session. If you have defined an IRequestHandler for open, then the model that you will be provided will be of type SessionModel you MUST call SessionModel.setOpen() to move the session into an open state. If the session is not open, then a ToolException should be thrown.
Great, that worked! However, the entire text gets printed after the "open project://..." line:
Hello World Console
open project://my_project/session_profiles/hw.ffsp
BEFOREAFTER
Hello World>
I want to display text before the "open project://..." line:
Hello World Console
BEFORE
open project://my_project/session_profiles/hw.ffsp
AFTER
Hello World>
I guess I could extend the Console.getBanner() method to print information before the "open project://.." line. Is that the right place to do it?
The console is designed to allow you to enter a request and then to display the response. The Open request starts with Open device:foo, you can't really have anythinig before.
One important thing to note, the console is designed for learning the SDK and is not the recomended way of interacting or displaying information.
Is there a reason that you want to display information about opening before the open step?
Displaying information before the "open" text in the response is purely for cosmetic reasons; in this specific case I want to display a copyright notice:
Hello World Console

open project://my_project/session_profiles/hw.ffsp
Welcome. Today's date is 10/05/2009
Hello World>
For now I have added this text to the getBanner() method.
