isActive abstract method

bool isActive(
  1. TreeViewNode<T> node
)

Returns whether or not the given TreeViewNode is enclosed within its parent TreeViewNode.

If the TreeViewNode.parent isExpanded (and all its parents are expanded), or this is a root node, the given node is active and this method will return true. This does not reflect whether or not the node is visible in the Viewport.

Implementation

bool isActive(TreeViewNode<T> node);
