Hi all,

Please help,

I have created ALV tree, with the help of standard program bcalv_tree_01. now i want to create it interative like DOUBLE CLICK on any ITEM or NODE. so i have define class and implement it with two method for event NODE_DOUBLE_CLICK and ITEM_DOUBLE_CLICK. and i have register it. when i display the tree it doesn't expand, but i comments the CALL METHOD gd_tree->set_registered_events it works fine. should i have to implement the event EXPAND_NO_CHILDREN also?

and what should be the code, becoz i am new in alv tree and oops. for sytex please refer BCALV_TREE_01.

please help as soon as possible.

Thanks in advance.

HI,

To understand the click events in a tree ; refer to the program SAPSIMPLE_TREE_CONTROL_DEMO.

Hi!

Ya you have to code for the method EXPAND_NO_CHILDREN

Where you will be defining the childs to the particular node.

the better example for it you can refer to SAPSIMPLE_TREE_CONTROL_DEMO

where

HANDLE_EXPAND_NO_CHILDREN method implemented shows the childs added and METHOD HANDLE_NODE_DOUBLE_CLICK

implemented to handle the doulbe click.

Regards.
