如何关闭和图标化JavaFx阶段

在我的Java Fx应用程序中,我创建了两个阶段。第一阶段是主控制器类HomeController中的默认阶段。第二个AddNewEmailController是通过调用showNewComposeNewEmail()类中的方法AddNewEmailController创建的。

新阶段创建得很好,但我尝试调用的方法都没有,比如关闭AddNewEmailController阶段,将在AddNewEmailController阶段工作。

如何让方法起作用?

我也想在HomeController阶段打开后无法访问AddNewEmailController阶段,就像弹出窗口一样。

我甚至无法将AddNewEmailController阶段变为 iconify

提前谢谢大家。

HomeController类:

public class HomeController implements Initializable {

// Initializes the controller class.
@Override
public void initialize(URL url, ResourceBundle rb) {
    // TODO
}
@FXML
public void windowClose() {
    Platform.exit();
}

@FXML
public void showNewComposeNewEmail() throws Exception {
    new AddNewEmailController().newnewcomposeNewEmailStage();
}
}

AddNewEmailController类:

public class AddNewEmailController implements Initializable {

public void setScreenParent(ScreensController screenParent) {
    myController = screenParent;
}

// Initializes the controller class.
@Override
public void initialize(URL url, ResourceBundle rb) {
    // TODO
}

public Stage newComposeNewEmail;

public void newnewcomposeNewEmailStage() throws IOException {
    newComposeNewEmail = new Stage();
    newComposeNewEmail.initStyle(StageStyle.UNDECORATED);
    newComposeNewEmail.initStyle(StageStyle.TRANSPARENT);

    Parent newComposeNewEmailRoot = FXMLLoader.load(getClass().getResource("/wakiliproject/Forms/AddNew/NewEmail/NewEmail.fxml"));

    StageDraggable.stageDraggable(newComposeNewEmailRoot, newComposeNewEmail);

    Scene newComposeNewEmailScene = new Scene(newComposeNewEmailRoot, 590, 670);

    newComposeNewEmail.setScene(newComposeNewEmailScene);
    newComposeNewEmail.show();
}

@FXML
private void newComposeNewEmailClose() {
    newComposeNewEmail.close();
}

@FXML
private void newComposeNewEmailIconify() {
    newComposeNewEmail.setIconified(true);
}
}

更新:

NewEmail FXML:

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

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="wakiliproject.Forms.AddNew.NewEmail.TryEMailController">
  <children>
    <Label layoutX="190.0" layoutY="61.0" onMouseClicked="#newComposeNewEmailStageIconify" text="Minimise Window" />
    <Label layoutX="300.0" layoutY="61.0" onMouseClicked="#newComposeNewEmailStageClose" text="Close Window" />
  </children>
</AnchorPane>

答案 0 :(得分:1)

在您的fxml中,您的controller

fx:controller="wakiliproject.Forms.AddNew.NewEmail.TryEMailController"

在您的代码中,类名是

AddNewEmailController

请使它们相同并重新检查,您的方法将被调用。
