Dear SDN members,
I am trying to use CL_SALV_TREE in a very simple way. I only want a simple tree with two columns, in which I would like to be able to navigate to subnodes etc...
The code I implemented is like this:
* Create instance
CALL METHOD cl_salv_tree=>factory
IMPORTING
r_salv_tree = gr_tree
CHANGING
t_table = it_produtos_cat.
* Get nodes reference
gr_nodes = gr_tree->get_nodes( ).
*Add first node
gr_node = gr_nodes->add_node(
related_node = key " empty at this moment
relationship = cl_salv_nodes=>if_salv_c_node_relation~parent
data_row = wa_produtos
visible = abap_true
expander = abap_true
enabled = abap_true
folder = abap_true ).
* Get Key of the node added
key = gr_node->get_key( ).
*Add first child
gr_node = gr_nodes->add_node(
related_node = key " key from the first node
relationship = cl_salv_nodes=>if_salv_c_node_relation~last_child
data_row = wa_produtos
visible = abap_true
expander = abap_true
enabled = abap_true
folder = abap_false ).
* display tree
gr_tree->display( ).
At the moment I have two problems, the major problem is that I do not have a expander icon to expand the first node...actually in this version of my code I can only see the first node. I am quite sure the relation is ok, because when I you the method
* Expand all nodes
gr_nodes->expand_all( ).
before display, all nodes apear. But all without expander icon and consequently it is not possible to expand or collapse the nodes.
The other problem is that when I select one or more nodes, and execute method
* Get selected nodes
gr_selections = gr_tree->get_selections( ).
lt_nodes = gr_selections->get_selected_nodes( ).
The nodes table lt_nodes is always empty!!!
Any ideas?! Specially for my first problem (Expander is not available) ?
Thanks for any help.
Regards
MPM
P.S.: I tried already the method SET_EXPANDER of class cl_salv_node.
