Re: [cdt-debug-dev] Events and CDI

You don't need to fire a CreatedEvent for local variables. The rendering of
the Variables view is asynchronous and messages you see are generated by the
label decorators. All you have to do is to implement the "getValue" method
of ICDIVariable.

Subject: [cdt-debug-dev] Events and CDI
Hi all,
I'm working on a debugger that uses the win32 and MS-provided
symbol-access APIs to support debugging of Visual Studio-compiled
applications. I've run into a problem with supporting variables and
thought that a CDI developer or a developer of the CDI gdb-mi debugger
could give me some pointers...
My first attempt at showing variables was to get method-local
variables and parameters working. ICDIStackFrame has a method
getLocalVariableDescriptors() that returns an array of variables
descriptors. I've implemented this method to return variable descriptors
for the local parameters of the current stack frame. What I observe in
Eclipse is that sometimes the <var-name> = <value> item is displayed in
the Variables view, sometimes "Pending ..." is displayed, and sometimes
"..." is shown.
I learned when implemented breakpoints that a CreatedEvent had to be
posted for each new breakpoint in addition to returning the breakpoint
object from the set<Type>Breakpoint. I thought that perhaps I needed to
do something similar for variables. I started by posting CreatedEvent's
when createLocalVariable() was called, but saw no change in behavior. I
also tried posting CreateEvent's from getLocalVariableDescriptors().
Again, no change in behavior.
Any thoughts on what I may be doing wrong?
Thanks in advance!
Thanks and Regards,
Matthew
