Hello,
I'm working with the cl_gui_column_tree class to build a user interface and i wonder if it's possible to remove the expander icons (not the icon for the opended/closed folder itself) of a tree at some places.
The standard layout would be something like this:
- Root (expanded)
- Node 1 (expanded)
Item 1
Item 2
+ Node 2 (unexpanded)
(Note that + and - are no folder icons but only the expander icons (some arrows)).
What I want to achieve is that there is no expander displayed in some cases and that a node is automatically expanded if it has subelements. The example above would look like this if i would be able to deactivate the expander icons for Node 1 and 2 (or at least overwrite the icons with the empty icon):
- Root
Node 1
Item 1
Item 2
Node 2
Item 3
Is this possible somehow? The 'expander' property of a Node seems to have no effect on this when set to initial.
An additional question goes to the default icons of folder or leaf nodes. I'd like to know their icon-code but I wasn't able to find these icons in the ICON table. Are they stored elsewhere or does anyone know their @XY@ codes?
Thanks for your help!
