void requestChildNodes ( [in] TreeExpansionEvent  Event)

Invoked when a node with children on demand is about to be expanded.

This event is invoked before the treeExpanding() event.

void treeCollapsed ( [in] TreeExpansionEvent  Event)

Called whenever a node in the tree has been successfully collapsed.

void treeCollapsing ( [in] TreeExpansionEvent  Event)
raises (ExpandVetoException
)

Invoked whenever a node in the tree is about to be collapsed.

Exceptions
ExpandVetoExceptionto notify the calling XTreeControl that collapsing TreeExpansionEvent::Node should fail.
void treeExpanded ( [in] TreeExpansionEvent  Event)

Called whenever a node in the tree has been successfully expanded.

void treeExpanding ( [in] TreeExpansionEvent  Event)
raises (ExpandVetoException
)

Invoked whenever a node in the tree is about to be expanded.
