normally a tree node has an arrow in front to expand the node and an item has an point cause it's not possible to expand.
Now our users are allways confused if they open a node and there is nothing inside. This can happen in our application cause they shall see the structure but not in every project every node has items.
They are used the behaviour of Microsoft Explorer where there is only an arrow in front in case there are other folders inside.
It would be good if there is a possiblity to display if the node has other nodes or items or not. So that it is not necessary to open the node. For example the node has then a point in front like a item? Or maybe nothing like in Microsoft Explorer.
Is there any possibilty?
Thanks in advance
