After reading JavaDoc for ILazyTreeContentProvider and Virtual Tables and Trees I am a bit confused. Do they really mean that with a simple ITreeContentProvider all elements have to be loaded when the tree is created? I expected that getChildren() would only be called when expanding an element (and hasChildren() to be called to determine whether the plus sign should be shown). Or are they intended for the case where some elements have many children?
