I implemented a CL_GUI_SIMPLE_TREE and a CL_GUI_TOOLBAR. There is one button in the toolbar, which should only be activated, in case a folder is selected in the tree.
How to implement that? Which event of CL_GUI_SIMPLE_TREE should I use?
Is this possible at all?
Another option would be, to check, which node is selected in the tree, when the user clicks a button in the toolbar. In case of the wrong node is selected, I would then send a message like 'Function not possible" ...
Thanks in advance!
