how to get only expanded node after open & close in CL_GUI_ALV_TREE?

Hi,

I have a tree structure using CL_GUI_ALV_TREE.

I would like to capture only the expanded nodes AFTER open and close operation.

If the user opens all the nodes and then closes them, I get all the nodes when using GET_EXPANDED_NODES.

I want to get only the expanded nodes that the user currently sees on the screen (so in open and close you will not get it as open).

whatever I tried doesn't work.

Do you have any idea how to do it?

Thanks,

Itay

this methods calls method of attribute MR_COLUMN_TREE without setting the parameter NO_HIDDEN_NODES to 'X'

that's why you get every node that is "open" even if not "visible"

as this attribute MR_COLUMN_TREE is protected, you cannot access it...

you should consider using an object of class CL_GUI_COLUMN_TREE directly in place of CL_GUI_ALV_TREE so that you can call the method with this parameter set...

you will have far more to do by hand but you will get more flexibility...
