Method treeChanged

core/tree.go:830–832

treeChanged must be called after any structural change to the [Tree] (adding or deleting nodes). It calls SendChangeEvent to notify of changes.

(original ...events.Event)

// change to the [Tree] (adding or deleting nodes).
// It calls SendChangeEvent to notify of changes.
func (tr *Tree) treeChanged(original ...events.Event) {
	tr.sendChangeEvent(original...)
}

// sendChangeEventReSync sends an [events.Change] event on the RootView node.
// If SyncNode != nil, it also does a re-sync from root.
