CL_SALV_TREE

[Former Member]

Hello All,

   In the class CL_SALV_TREE we can get the node information from method GET_NODES and selections from the method GET_SELECTIONS.

But this class do not have any method that will retrieve expanded nodes.

Event IF_SALV_EVENTS_TREE~EXPAND_EMPTY_FOLDER will only trigger on node which have empty nodes.

I have seen in the package of the class CL_SALV_TREE , there is another class CL_SALV_GUI_TREE, which has the method GET_EXPANDED_NODES.

The class CL_SALV_TREE internally forms a tree using class CL_SALV_GUI_TREE, so we can handle the events triggered in CL_SALV_GUI_TREE in our local implementations.

Is there any way we can get the expanded node details using class CL_SALV_TREE.

We can also use the class CL_GUI_COLUMN_TREE which have majority of functions, but I am using the class CL_SALV_TREE.

With regards,

Is this what you need: cl_salv_tree->get_selections( )->get_selected_nodes( ) ?

This method also returns the selected nodes.

Hello Evgeniy,

       Thank you for your reply. I am looking for nodes which are expanded, not for selected.

Oh.. I think there is only one way: recursively get nodes and check that they have visible child nodes.

Something like this (it's a conept code add some checks to prevent dumps 😞

form f1 using p_node type ref to cl_salv_node.

     data(nodes) = p_node->get_children( ).

     loop at nodes assigning field-symbol(<fs>).

          try.

               data(child) = <fs>-node->get_first_child( ).

               if child->is_visible.

                    "your <fs>-node is expanded

                    "do what you need

                    "and then lets check child's children

                    perform f1 using child.

               else.

                    "your <fs>-node is NOT expanded

               endif.

          catch cx_salv_msg.

               "there will be exception if node has no children

               "so your <fs>-node can't be expanded.

          endtry.

     endloop.

endform.

And call it:

perform f1 using cl_salv_tree_object->get_nodes( )->get_root_node( ).

Hello Evgeniy,

Those methods are not working. I am using the class CL_GUI_ALV_TREE, which has more flexibility.

Hi,

you can use CL_GUI_COLUMN_TREE  better or CL_GUI_ALV_TREE, the last one has many methods, may you need them later.

and there are many actions, Drag, Drop, double click, context menu.
