RE: [cdt-dev] Detecting variable closing

["Mikhail Khodjaiants" <Mikhail.Khodjaiants@xxxxxxx>]

Volodya,

I don't think there is a "legitimate" way to detect when a var-object is
no longer needed by the Variables view. The view asynchronously requests
the information needed to display it's content. It doesn't notify the
backend if a previously requested object is no longer needed.
Try to post this question to the platform-debug-dev@xxxxxxxxxxx mailing
list, maybe they have a solution.

Regards,
Mikhail

Subject: [cdt-dev] Detecting variable closing


Hello !

Is there an easy way to detect when a variable (for example,
corresponding to a structure) in the variable view is collapsed by the
user?

For a background -- the structure variable might be huge, so reading it
all from target on each -var-update can be slow. I want to detect when
the variable is closed and send a special gdb command that prevents
updating this variable on -var-update -- after all, the children of the
variable are not visible anyway. The variable is not necessary a
top-level one.

Thanks in advance,
Volodya
