There is a method in the WorkbenchImages class called
getImageDescriptorFromProgram(String filename, int offset). The
documentation says that "This consults the plugin for extension and
obtains its installation location. All requested images are assumed to be
in a directory below and relative to that plugin's installation
directory.". Can somebody please let me know what is the expected value
for the filename parameter here. Is it just a filename, a complete URL or
a relative URL in the bundle context.
Warm Regards,
Rajesh

Run Eclipse under debug control and set a breakpoint in the interesting
methods. See how things get there. It seems to me, looking at the
code, that it could only be used to retrieve things that have been
cached by some other part of the system. So perhaps your predecessor
was using it as a sneaky (no-API) way to gain access to some images.
When I set a breakpoint there, I don't even see it get called...
Does your software ever actually call this method today. If so, use the
debugger to trace into the behavior of the method that way...
