如何在 Pane 中加载 fxml 文件?
How to load fxml file inside Pane?
如果我们有一个 Stage
那么 Scene
包括 2 Pane
第一个 Pane
包含 Button
而第二个 Pane
是空的
我们可以在第二个 Pane
中加载其他 fxml 文件吗?
fxml1: VBox
|_Pane1-->Button
|_Pane2
///////////////
fxml2: Pane--> Welcome to fxml 2
"when we click the button load the fxml2 inside Pane2 of fxml1"
然后点击后
====我终于在尝试后找到了这个作品!====谢谢大家
@FXML Pane secPane;
public void loadFxml (ActionEvent event) {
Pane newLoadedPane = FXMLLoader.load(getClass().getResource("/application/fxml2.fxml"));
secPane.getChildren().add(newLoadedPane);
}
你可以这样实现:
public void start(Stage primaryStage) throws IOException {
primaryStage.setTitle("Title");
primaryStage.setScene(createScene(loadMainPane("path_of_your_fxml")));
primaryStage.show();
}
private Pane loadMainPane(String path) throws IOException {
FXMLLoader loader = new FXMLLoader();
Pane mainPane = (Pane) loader.load(
getClass().getResourceAsStream(path));
return mainPane;
}
private Scene createScene(Pane mainPane) {
Scene scene = new Scene(mainPane);
return scene;
}
然后您可以创建一个单独的 class 调用 Navigation 来存储您所有的 fxml 路径:
public class Navigator {
private final String P1;
private final String P2;
//then you can implement getters...
public String getP1() {
return P1;
}
public String getP2() {
return p2;
}
private static FxmlController Controller;
public static void loadPane(String fxml) {
try {
FxmlController.setPane(
(Node) FXMLLoader.load(Navigator.class.getResource(fxml)));
} catch (IOException e) {
e.printStackTrace();
}
}
public Navigator() throws IOException {
this.P1 = "p1.fxml";
this.P2 = "p2.fxml";}
然后您可以在您的按钮中加载您的窗格,如下所示:
@FXML
private void btnAction(ActionEvent event) throws IOException {
Navigator.load(new Navigator().getP1());
..
.
只需替换控制器中的字段 class 不会更改场景图。
secPane
只是对场景图中节点的引用。
如果secPane
只是一个占位符,您可以在父子列表中替换它:
public void loadFxml (ActionEvent event) {
// load new pane
Pane newPane = FXMLLoader.load(getClass().getResource("/application/Login2.fxml"));
// get children of parent of secPane (the VBox)
List<Node> parentChildren = ((Pane)secPane.getParent()).getChildren();
// replace the child that contained the old secPane
parentChildren.set(parentChildren.indexOf(secPane), newPane);
// store the new pane in the secPane field to allow replacing it the same way later
secPane = newPane;
}
这当然假定 getClass().getResource("/application/Login2.fxml")
产生正确的资源而不是 return null
(如果没有具有给定名称的资源可用)
经过尝试,我终于找到了这个作品!
@FXML Pane secPane;
public void loadFxml (ActionEvent event) {
Pane newLoadedPane = FXMLLoader.load(getClass().getResource("/application/fxml2.fxml"));
secPane.getChildren().add(newLoadedPane);
