Class TreeNodeViewSkin<T>

java.lang.Object
javafx.scene.control.SkinBase<TreeNodeView<T>>
com.dlsc.gemsfx.treeview.TreeNodeViewSkin<T>
Type Parameters:
T - the type of the value stored in each tree node
All Implemented Interfaces:
javafx.scene.control.Skin<TreeNodeView<T>>
public class TreeNodeViewSkin<T> extends javafx.scene.control.SkinBase<TreeNodeView<T>>
Default skin for TreeNodeView.

The skin computes node positions for regular and compact layouts, creates cells through the view's cell factory, and draws links using the configured link strategy.
