It's actually quite easy--just find a user-visible text string somewhere in the
viscinity of what you're looking for, and grep for it in the git repository.
For example, some days ago I wanted to know which class implements the dropdown
button component that can be seen in some of the NetBeans toolbar. I hovered
over the one in the Java editor, and got a tooltip that said "Go back to
StringUtil.java". This meant that somewhere in the NetBeans codebase, there is
a string called "Go back to", which should bring me in the right direction.
Then, from the checked-out netbeans sources, I do:
git grep 'Go back to'
This shows me a few results, with one being relevant:
ide/editor/src/org/netbeans/modules/editor/impl/actions/Bundle.properties:NavigationHistoryBackAction_Tooltip=Go
back to {0}
Then I do:
git grep 'NavigationHistoryBackAction_Tooltip'
This takes me to
ide/editor/src/org/netbeans/modules/editor/impl/actions/NavigationHistoryBackAction.java
.
In that file I find a method call DropDownButtonFactory.createDropDownButton,
which is in the class org.openide.awt.DropDownButtonFactory. And that's the
class I was looking for.
In the end, you usually just end up having to open up one or two NetBeans
modules in the IDE to work on a particular bug, or inspect a particular feature.

Hi Tim,
That is most impressive, and yet terrifying at the same time. It raises even
more questions for me. How does anyone know where anything is?
Probably not for discussion here but, what use is software engineering, design
methodologies etc., is software development just an enormous hackathon?
Food for thought.
Many thanks to everyone who replied to my original post.
Jeremy
