I recently got back to hacking my tune-teaching program, and it
is going superbly. I should have something to show in a week
Along the way, I'm starting to notice how tidbits of information
I gather become "knowledge nuggets" that are worth storing
and retreiving in some FAQ-centric way.
1. I found out (or rediscovered, assuming I once knew it) the
events generated when clicking on different Java Swing
The topic relationships here are generates/generated by.
The FAQ-style questions one would like to see are in the
What event does <component> generate when clicked?
What components generate a <eventType> event?
2. Then there are other little knowledge nuggets, like:
To deselect all radio buttons in a ButtonGroup, add
an invisible button and execute its doClick() method.
Q-form: How do you deselect all radio buttons in a
3. Finally, and more deeply:
Selecting a button in a radio group does NOT generate
action events for the deselected buttons. Although other
buttons in the group have their appearance changed, it is
up to the application to carry out the appropriate
de-selection semantics (if any) for every other button in
Q-form: What events are generated for the buttons in a
Now, #2 was taken out of the class comments. But items #1 & #3
were discovered by a combination of fooling around, reading,
and controlled experimentation.
Clearly, there is a strong knowledge-component in this discovery
process. Each "nugget" developed in the process accumulates
towards a developer's "expertise rating".
If the ability to do remote collaboration on a design is one
important tool we need to bootstrap open source development
of a DKR, then a FAQ-style expertise system has considerable
DKR-ness, in and of itself.
[Somewhere in the open source community, I recall seeing a
FAQ-generating tool. But I don't recall where, or how good
