java - 如何使辅助 anchor 板扩展其尺寸以适合主 anchor 板？

标签 java javafx javafx-8 fxml

我不知道如何将另一个 View 中的辅助 Anchorpane 设置到主 View 的边界(在 fxml 代码中，它将是名为 holderPane 并且有灰色区域)，这样当窗口展开时，它也会随之拉伸(stretch)。我通过 SceneBuilder 完成所有工作。

这是在我最大化窗口之后:

My GettinStart view, which includes another view - StoksView

灰色区域就是那个Anchorpane，我尝试将另一个锚定区域绑定(bind)/设置到它。在 GettingStart.fxml 主 Controller 的代码中，我写的是:

@FXML
    private AnchorPane holderPane;

    private void setNode(Node node) {
        holderPane.getChildren().clear();
        holderPane.getChildren().add((Node) node);
    }
    @FXML
    public void initialize() {

        try {

            AnchorPane marketPane = FXMLLoader.load(getClass().getResource("../view/StocksView.fxml"));

            for (Node node:sidePane.getChildrenUnmodifiable()) {
                System.out.println(node.getAccessibleText());
            }

            for (Node node : sidePane.getChildren()) {
                if (node.getAccessibleText() != null) {
                    node.addEventHandler(MouseEvent.MOUSE_PRESSED, (MouseEvent ev) -> {
                        switch (node.getAccessibleText()) {
                            case "storesMenu":
                                setNode(marketPane);
                                txtCurrentWindow.setText("Stores");
                                break;

其中 StocksView.fxml 具有正常形式的灰色区域的尺寸。

StocksView.fxml

   <?xml version="1.0" encoding="UTF-8"?>

<?import com.jfoenix.controls.JFXTabPane?>
<?import javafx.scene.control.Tab?>
<?import javafx.scene.effect.DropShadow?>
<?import javafx.scene.layout.AnchorPane?>

<AnchorPane id="AnchorPane" prefHeight="540.0" prefWidth="780.0" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1">
   <children>
      <JFXTabPane layoutX="323.0" layoutY="191.0" prefHeight="540.0" prefWidth="780.0" style="-fx-background-color: #fff;" tabClosingPolicy="UNAVAILABLE" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
         <tabs>
            <Tab closable="false" text="Manage Sheets">
              <content>
                <AnchorPane minHeight="0.0" minWidth="0.0" prefHeight="180.0" prefWidth="200.0" />
              </content>
            </Tab>
            <Tab closable="false" text="Store">
               <content>
                  <fx:include source="TabStockView.fxml" />
               </content></Tab>
         </tabs>
         <effect>
            <DropShadow />
         </effect>
      </JFXTabPane>
   </children>
</AnchorPane>

最佳答案

只需将 anchor 设置为 0 即可使父级 AnchorPane 调整子级的大小以填充其整个区域:

private void setNode(Node node) {
    AnchorPane.setBottomAnchor(node, 0);
    AnchorPane.setTopAnchor(node, 0);
    AnchorPane.setLeftAnchor(node, 0);
    AnchorPane.setRightAnchor(node, 0);

    holderPane.getChildren().setAll(node);
}
