ALV Tree Context Menu

[Former Member]

Hello Friends,

We are working on ALV Trees.

this is the sample code:

<b>CLASS LCL_TREE_EVENT_RECEIVER DEFINITION.

PUBLIC SECTION.

METHODS: HANDLE_NODE_CM_REQ

FOR EVENT NODE_CONTEXT_MENU_REQUEST OF CL_GUI_ALV_TREE

IMPORTING NODE_KEY MENU.

ENDCLASS. </b>

<b>CLASS LCL_TREE_EVENT_RECEIVER IMPLEMENTATION.

METHOD HANDLE_NODE_CM_REQ.

CALL METHOD MENU->CLEAR.

CALL METHOD MENU->ADD_FUNCTION

EXPORTING

FCODE = 'DEL_SUBTREE'

TEXT = 'Delete Subtree'. "Delete Subtree

CALL METHOD MENU->ADD_FUNCTION

EXPORTING

FCODE = 'ADD_SUBTREE'

TEXT = 'Add Subtree'. "Add Subtree</b>

Then we handle the node that is selected by the user.

Now our problem is can the context menu be created dynamically based on the node selected.

For example:

If my ALV Tree is

<b>Node A

>Node B

>>Node C

>Node B

>>Node C</b>

So, if I right click on Node A, I should get only 'Add B' or 'Delete B'.

if I click on Node B, I should get 'Add C' or 'Delete C'.

Depending on the node on which I right click the context menu should change. How to achieve that.

regards,

Raju.

Hi,

The method HANDLE_NODE_CM_REQ FOR EVENT NODE_CONTEXT_MENU_REQUEST has NODE_KEY as importing paramer.

Use that NODE_KEY in method GET_OUTTAB_LINE' and get the node details.

Based on that you use 'Add Function' to have a relevant context menu.

Use Method GET_FIRST_CHILD to identify the child nodes.

Hope this helps
