将焦点设置在ControlsFX中的PropertySheet项目节点上(Set focus on PropertySheet Item Node in ControlsFX)

将焦点设置在ControlsFX中的PropertySheet项目节点上(Set focus on PropertySheet Item Node in ControlsFX)

我想将焦点放在ControlsFX中的PropertySheet.Item Node（例如TextField ）上。 PropertySheet Item具有唯一的名称，因此我可以找到PropertySheet.Item ，其代码为propertySheet.getItems().get(i).getName() 。 但是没有API来获取与属性项对应的Node 。 我看到的唯一解决方案是使用getChildrenUnmodifiable方法遍历场景图 。 但是，当我使用此方法遍历PropertySheet ，它返回：

PropertySheet@1ab0e7e0[styleClass=property-sheet] BorderPane@46e1b462 ToolBar@93ba99a[styleClass=tool-bar] SegmentedButton@d5c968[styleClass=segmented-button] HBox@1c3283db ToggleButton@2fffaccc[styleClass=toggle-button left-pill]''

我没有得到任何Propertysheet节点，如TextField或ComboBox 。 有可能吗？ 谢谢。

I want to set focus on PropertySheet.Item Node (for example TextField) in ControlsFX. PropertySheet Item have unique name, so i can find PropertySheet.Item with code propertySheet.getItems().get(i).getName(). But there is no API to get Node which corresponds to property item. The only solution i see is to walk scene graph with method getChildrenUnmodifiable. But when i traverse PropertySheet with this method it returns:

PropertySheet@1ab0e7e0[styleClass=property-sheet] BorderPane@46e1b462 ToolBar@93ba99a[styleClass=tool-bar] SegmentedButton@d5c968[styleClass=segmented-button] HBox@1c3283db ToggleButton@2fffaccc[styleClass=toggle-button left-pill]''

I don't get any Propertysheet Nodes such as TextField or ComboBox. Is it possible to do it? Thank you.

我找到了解决方案。 您必须使用setPropertyEditorFactory和全局hashmap变量来存储所有节点，以便稍后访问它。 示例代码如下。

public Map<String, Node> nodes = new HashMap<>(); SimpleObjectProperty<Callback<PropertySheet.Item, PropertyEditor<?>>> propertyEditorFactory = new SimpleObjectProperty<>(this, "propertyEditor", new DefaultPropertyEditorFactory()); propertySheet.setPropertyEditorFactory((PropertySheet.Item param) -> { PropertyEditor node = propertyEditorFactory.get().call(param); nodes.put(uniquePropertyName, node.getEditor()); return node; });

在此之后，您可以将属性Node聚焦于：

nodes.get(propertyName).requestFocus();

I found a solution. You must use setPropertyEditorFactory and global hashmap variable which will store all Nodes, so you can access it later. Sample code below.

public Map<String, Node> nodes = new HashMap<>(); SimpleObjectProperty<Callback<PropertySheet.Item, PropertyEditor<?>>> propertyEditorFactory = new SimpleObjectProperty<>(this, "propertyEditor", new DefaultPropertyEditorFactory()); propertySheet.setPropertyEditorFactory((PropertySheet.Item param) -> { PropertyEditor node = propertyEditorFactory.get().call(param); nodes.put(uniquePropertyName, node.getEditor()); return node; });

After this you can focus property Node with:

nodes.get(propertyName).requestFocus();
