我正在使用 JavaFX 开发应用程序，对于 View ，我使用 FXML。

<AnchorPane id="AnchorPane" fx:id="dashboard" prefHeight="400.0" prefWidth="600.0" stylesheets="@css/dashboard.css" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.hassanalthaf.telemart.viewmodels.DashboardViewModel">
   <children>
      <MenuBar maxWidth="600.0" minWidth="600.0" prefWidth="600.0">
        <menus>
          <Menu mnemonicParsing="false" text="File">
            <items>
              <MenuItem mnemonicParsing="false" text="Close" />
            </items>
          </Menu>
          <Menu mnemonicParsing="false" text="Help">
            <items>
              <MenuItem mnemonicParsing="false" text="About" />
            </items>
          </Menu>
        </menus>
      </MenuBar>
      <AnchorPane fx:id="home" layoutY="29.0" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="371.0" prefWidth="600.0" />
      <AnchorPane fx:id="about" layoutY="29.0" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="371.0" prefWidth="600.0" />
      <AnchorPane fx:id="users" layoutY="29.0" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="371.0" prefWidth="600.0" />
   </children>
</AnchorPane>

如您所见，此片段包含一些 <AnchorPane> ID 为 home 的 s , about , users .这些是我的应用程序的单独页面。要操作这些 Pane ，我必须像这样将它们注入(inject)到我的代码中:

@FXML
private AnchorPane home;

@FXML
private AnchorPane about;

@FXML
private AnchorPane users;

这可能现在看起来很整洁，但是当超过 20 页时，它可能看起来有点凌乱和乏味。有什么方法可以将它们以干净高效的方式分组到数组或其他东西中吗？

最佳答案

你可以使用 fx:define和 fx:reference将元素放在 List 和场景图中，并将列表注入(inject) Controller :

<AnchorPane id="AnchorPane" fx:id="dashboard" prefHeight="400.0" prefWidth="600.0" stylesheets="@css/dashboard.css" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.hassanalthaf.telemart.viewmodels.DashboardViewModel">
   <fx:define>
        <!-- create panes and store them in a list -->
        <ArrayList fx:id="panes">
            <AnchorPane fx:id="home" layoutY="29.0" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="371.0" prefWidth="600.0" />
            <AnchorPane fx:id="about" layoutY="29.0" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="371.0" prefWidth="600.0" />
            <AnchorPane fx:id="users" layoutY="29.0" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="371.0" prefWidth="600.0" />
        </ArrayList>
    </fx:define>
    <children>
        <MenuBar maxWidth="600.0" minWidth="600.0" prefWidth="600.0">
            <menus>
                <Menu mnemonicParsing="false" text="File">
                    <items>
                        <MenuItem mnemonicParsing="false" text="Close" />
                    </items>
                </Menu>
                <Menu mnemonicParsing="false" text="Help">
                    <items>
                        <MenuItem mnemonicParsing="false" text="About" />
                    </items>
                </Menu>
            </menus>
        </MenuBar>
        <!-- add panes in the list to scene graph -->
        <fx:reference source="home"/>
        <fx:reference source="about"/>
        <fx:reference source="users"/>
    </children>
</AnchorPane>

Controller

@FXML
private List<AnchorPane> panes;
