drag&drop

Hi experts,

I have a Problem with drag&drop within simple_tree_control.

Drop after a node is no problem, but how can I find out, if the draged node must be inserted after or before the node that are marked for drop.

Please send me an answer.

Thx for advance

hi,

take a look to program "SIMPLE_TREE_DRAG_DROP_DEMOF01"

you can control the behavior - storing in the internal table -

probably you need various methods for this.!

hi,

the structure of the internal table e.g. MTREESNODE shows you how to handle a node or a leaf.

e.g.

lines of code in "SIMPLE_TREE_DRAG_DROP_DEMOF01" at 158.

if you want to drag new objects as node - you need one method(event-handling - ON DROP)

and one method for dragging new objects as leaf.

in the event handler you have to read your int.table to figure out is it a leaf or node where to append.
