Hi.
Im writing an IDE that uses the JDT debugger. It works to some extent -
it is possible to create a line break point. Running the code in debug
mode then stops at the indicated line.
The only problem is that I can't make the little icon appear in the
vertical ruler. Im using the method
JDIDebugModel.createLineBreakpoint(...) (and I can see that JDT does
excatly the same), which should create a marker in the ruler.
My first guess was that the image that should be inserted was not
available - so I copied the "icon" directory into my plug-in workspace
directory - but it didn't help.
Any help will be appreciated,
Mads

The editor displays annotations in its vertical ruler. The editor knows
about breakpoints because each breakpoint has an associated marker, which
displays as an "annotation" in the ruler. When the marker changes
(created/modified/removed), a resource delta is fired and the editor knows
to update the annotation. The image for a breakpoint is retrieved from a
debug model presentation - in this case, the Java debugger contributes a
"model presentation" that is used to render elements from the Java debug
model.
See the Java editor as an example.

Im writing an IDE for the language Beta. The Beta compiler generates Java
bytecodes, so it is natural to reuse some of the clases in JDT. In fact the
class I use as the launch delegate is
JavaLocalApplicationLaunchConfigurationDelegate.
So launching applications works perfectly fine! But debugging is more
complicated. I've made the ruler respond to double clicks and let the
corresponding action be to insert a breakpoint. In the code I have the
code: JDIDebugModel.createLineBreakpoint(resource, "beta.program", lineNo, -1,
-1, 0, true, null).
And this almost works. The only thing missing is the little icon appearing in
the ruler - the debugger stops executing when reaching the specified line.
So what Im really asking: How do I make the little icon appear in the ruler?
Thanks,
Mads
