current selected stack frame [message #161554]

Hi all,
I'm developing a debugger and I just finished the "watch expression"
evaluation. My debugger evaluates all expressions for each
stack frame so every stack frame has its own results. My desired behaviour
is: every time the user clicks on a stack frame in the debug view, the
expression view will be refreshed and display the values associated to the
current stack frame.

My questions are:
How do I know which stack frame has been selected and when?
How do I trigger a refresh in the Expression view?(also I do I retrieve
it)

thanks for your time

ciao
Alberto

Which version of Eclipse? In 3.0, there is a new IWatchExpression debug
model element. It is passed a stack frame in which to evaluate its value.
Debug models may contribute a delegate to evaluate watch expression values
as applicable. Each time a stack frame is selected, the watch expression is
passed the new context. In 2.1, you have to listen to selection changes in
the debug view.

As well, see DebugUITools.getDebugContext().
