[cdt-dev] Detecting variable closing

[Vladimir Prus <vladimir@xxxxxxxxxxxxxxxx>]

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
