Right click popup on ctree/clist

[Markus Lausser <sgop users sourceforge net>]

Hello.

I have a general problem. WHat is the best solution for the following
problem:
I want a right click popup on a clist/ctree entry. After activating a item
in the popup the according callback should act on the entry clicked.
The problem is: between right click and activating the entry the contents of
the clist/ctree could have changed, the entry even could be non
existent then.

At the moment i do it like this: saving the clist widget and row in a global
var, and using these information in the callbacks, no matter what changes 
were made to the clist after saving this stuff. And as expected: sometimes
the callbacks use the wrong clist entry..sometimes even a row number, that
does not exist anymore.

Does anyone know a _good_ solution?
The solution should be independent of existing data attached to the rows.
What i mean is: sometimes there is data attached sometimes there is not.

Thanks in advance.

Markus.
