xworker.javafx.control.TreeView.dml Maven / Gradle / Ivy
The TreeView control provides a view on to a tree root (of type TreeItem). By using a TreeView, it is possible to drill down into the children of a TreeItem, recursively until a TreeItem has no children (that is, it is a leaf node in the tree). To facilitate this, unlike controls like ListView, in TreeView it is necessary to only specify the root node.

Represents the cell factory that will be used for creating TreeCells, which are used to represent items in the TreeView.
]]>
Specifies whether this TreeView is editable - only if the TreeView and the TreeCells within it are both editable will a TreeCell be able to go into their editing state.
]]>
Specifies whether this control has cells that are a fixed height (of the specified value).

The FocusModel provides the API through which it is possible to control focus on zero or one rows of the TreeView.
]]>
Property representing the root node of the TreeView.
]]>
The SelectionModel provides the API through which it is possible to select single or multiple items within a TreeView, as well as inspect which rows have been selected by the user.
]]>
Property that represents whether or not the TreeView root node is visible.

需要实现的方法：
- TreeCell<T> call(TreeView<T> param)
创建TableCell，默认实现通过子节点创建。

用于定义动作行为，通过子节点添加具体的动作行为。
只有第一个动作模型（本节点类型）生效，会忽略后面添加的动作模型。

需要重写下面的方法：
- void changed(ObservableValue<? extends T> observable, T oldValue, T newValue)
