using modality in a popup window javafx - javafx

Question

I kept a popup dialog on a pane and it came at the top of the other components. Now I want to disable accessing all the other components of the program. How to do it?

Answer 1

The popup API does not have an initModality(Modality.APPLICATION_MODAL); method which is exactly what you want. In this case, you can make your popup window a stage and use the method mentioned above.

Answer 2

This is for #Xsleek in solution, example code:-
package popupexample;
import java.text.SimpleDateFormat;
import java.util.Date;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBoxBuilder;
import javafx.scene.text.Text;
import javafx.stage.Modality;
import javafx.stage.Stage;

public class PopUpExample extends Application {
#Override
public void start(Stage primaryStage) {
Button btn = new Button();
btn.setText("Say 'Hello World'");
btn.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
popupErrorMsg();
}
});
StackPane root = new StackPane();
root.getChildren().add(btn);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}

public static void main(String[] args) {

}
public void popupErrorMsg() {
final Stage myDialog = new Stage();
myDialog.initModality(Modality.APPLICATION_MODAL);
Button okButton = new Button("Ok");
okButton.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent arg0) {
myDialog.close();
}
});
Date todayDate = new Date();
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
Scene myDialogScene = new Scene(VBoxBuilder.create()
.children(new Text("Please Enter Validate Date \n \t "+ dateFormat.format(todayDate)), okButton)
.spacing(30)
.alignment(Pos.CENTER)
.padding(new Insets(10))
.build());
myDialog.setScene(myDialogScene);
myDialog.show();
}
}
