javafx => Windows

Ein neues Fenster erstellen

Um einige Inhalte in einem neuen Fenster anzuzeigen, muss eine Stage erstellt werden. Nach der Erstellung und Initialisierung muss show oder showAndWait für das Stage Objekt aufgerufen werden:

// create sample content
Rectangle rect = new Rectangle(100, 100, 200, 300);
Pane root = new Pane(rect);
root.setPrefSize(500, 500);

Parent content = root;

// create scene containing the content
Scene scene = new Scene(content);

Stage window = new Stage();
window.setScene(scene);

// make window visible
window.show();

Anmerkung: Dieser Code muss auf dem JavaFX-Anwendungsthread ausgeführt werden.

Benutzerdefiniertes Dialogfeld erstellen

Sie können benutzerdefinierte Dialoge erstellen, die viele Komponenten enthalten, und viele Funktionen dafür ausführen. Es verhält sich wie die zweite Stufe auf der Eigentümerstufe.
Im folgenden Beispiel wird eine Anwendung erstellt, die Person in der Tabellensicht der Hauptphase zeigt und eine Person in einem Dialog (AddingPersonDialog) erstellt. GUIs, die mit SceneBuilder erstellt wurden, können jedoch mit reinem Java-Code erstellt werden.

Beispielanwendung:

AppMain.java

package customdialog;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class AppMain extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("AppMain.fxml"));
        Scene scene = new Scene(root, 500, 500);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }

}

        AddPersonDialogController dialogController = fxmlLoader.<AddPersonDialogController>getController();
        dialogController.setAppMainObservableList(tvObservableList);

        Scene scene = new Scene(parent, 300, 200);
        Stage stage = new Stage();
        stage.initModality(Modality.APPLICATION_MODAL);
        stage.setScene(scene);
