I want to select one row and then to open a new window when I click the button Select to open a new window. Can you help me to fix the code?
Replace the btnYes.setOnAction with the following :
btnYes.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
Person item = leaderListView.getSelectionModel().getSelectedItem();
if (item != null) {
StackPane pane = new StackPane();
Scene scene = new Scene(pane);
Stage stage = new Stage();
stage.setScene(scene);
pane.getChildren().add(new TextField(item.getAliasName()));
stage.show();
}
}
});
It should be this the action of the btnYes:
btnYes.setOnAction(new EventHandler<ActionEvent>()
{
#Override
public void handle(ActionEvent event)
{
Person item = leaderListView.getSelectionModel().getSelectedItem();
if (item != null) {
StackPane pane = new StackPane();
Scene scene = new Scene(pane);
Stage stage = new Stage();
stage.setScene(scene);
pane.getChildren().add(new TextField(item.getAliasName()));
stage.show();
}
}
});
(there might be an axtra braket, just edited online.)
Also, this is exactly the same code as in the list doubleclick event, might want to put it in a diferent method, so that you dont repeat code:
public void openNewWindow(){
Person item = leaderListView.getSelectionModel().getSelectedItem();
if (item != null) {
StackPane pane = new StackPane();
Scene scene = new Scene(pane);
Stage stage = new Stage();
stage.setScene(scene);
pane.getChildren().add(new TextField(item.getAliasName()));
stage.show();
}
I want to update the code of this example:

Is there a way to add MODAL capability to a context menu?

import javafx.scene.layout.Pane;
import javafx.stage.Stage;
import javafx.stage.WindowEvent;
public class ContextMenuSample extends Application
{
public static void main(String[] args)
{
launch(args);
}
#Override
public void start(Stage stage)
{
stage.setTitle("ContextMenuSample");
Scene scene = new Scene(new Group(), 450, 250);
Label toLabel = new Label("To: ");
TextField notification = new TextField();
final ContextMenu contextMenu = new ContextMenu();
contextMenu.setAutoHide(false);
contextMenu.setOnShowing(new EventHandler<WindowEvent>()
{
public void handle(WindowEvent e)
{
System.out.println("showing the context menu");
}
});
contextMenu.setOnShown(new EventHandler<WindowEvent>()
{
public void handle(WindowEvent e)
{
System.out.println("context menu has been shown");
}
});
MenuItem closeItem = new MenuItem("Close");
closeItem.setOnAction(new EventHandler<ActionEvent>()
{
public void handle(ActionEvent e)
{
contextMenu.hide();
}
});
MenuItem colorItem = new MenuItem("Choose", new ColorPicker());
colorItem.setOnAction(new EventHandler<ActionEvent>()
{
public void handle(ActionEvent e)
{
System.out.println("Preferences");
}
});
GridPane contextGridPane = new GridPane();
Pane pane = new Pane();
pane.getChildren().add(contextGridPane);
contextMenu.getItems().addAll(colorItem, deleteItem// , subsystem1,
// radioItem
);
toLabel.setContextMenu(contextMenu);
GridPane grid = new GridPane();
grid.setVgap(4);
grid.setHgap(10);
grid.setPadding(new Insets(5, 5, 5, 5));
grid.add(toLabel, 0, 0);
grid.add(notification, 1, 0);

stage.setScene(scene);
stage.show();
}

When the user clicks on the label "To", a context menu appears. I wish to have modal capability for this context menu such that the user is not able to do anything else on the application unless some operation is performed on the context menu. Also, when the context menu is active, the user should not be able to click anywhere else on the application.
Regards,
The easiest solution would be to call another Stage and set its modality with initModality before you show the stage. You probably want to use Modality.APPLICATION_MODEL as far as I understood you.
Here is a small example derived from yours (btw your code was not even runnable, it had errors)
public class ContextMenuSample extends Application
{
public static void main(String[] args)
{
launch(args);
}
#Override
public void start(final Stage stageOne)
{
final Stage stageTwo = new Stage();
stageTwo.initModality(Modality.APPLICATION_MODAL);
final Pane layoutOne = new HBox(10);
Pane layoutTwo = new HBox(10);
Label labelOne = new Label("click");
Label labelTwo = new Label("other click");
labelOne.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent event) {
stageTwo.show();
}
});
labelTwo.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent event) {
stageTwo.close();
}
});
Scene sceneOne = new Scene(layoutOne);
Scene sceneTwo = new Scene(layoutTwo);
layoutOne.getChildren().add(labelOne);
layoutTwo.getChildren().add(labelTwo);
stageOne.setScene(sceneOne);
stageTwo.setScene(sceneTwo);
stageOne.show();
}
}
I am trying to get my head around the JavaFX stuff...
My program is a WindowBuilder based Gui, and I want a JavaFX graph, and a JavaFX live video-feed displayed in my app.
How do I implement it in my code? I have tried this, but I couldn't get it runnning.
The data feed isnt the problem. I just need to view it inside my JFrame as small squares...
Confused now :(
Here is my code: (I am sorry that it is a tad long, but I blame the examplecode from JavaFX :p
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.UIManager;
import java.awt.Canvas;
import java.awt.SystemColor;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import javax.swing.UIManager.*;
/**

*/
public class MyClientApp extends JFrame {
/**

*/
private static final long serialVersionUID = 1L;
protected static final String BufferedWriter = null;
JFrame frame;
private JTextField textFieldUsername;
/**
* Create the application.
*/
public MyClientApp(BufferedWriter serverDataOut, BufferedReader serverDataIn) {
initialize();
}
/**
* Initialize the contents of the frame.
*
* #param serverDataOut
*
*/
private void initialize() {
try {
for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) {
if ("Nimbus".equals(info.getName())) {
UIManager.setLookAndFeel(info.getClassName());
break;
}
}
} catch (Exception e) {
// Nimbus Theme not avaliable
}
frame = new JFrame();
frame.setResizable(false);
frame.setTitle("*********** My Program ***********");
frame.setBounds(320, 130, 730, 570);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
Canvas canvasTemp = new Canvas();
canvasTemp.setBackground(SystemColor.window);
canvasTemp.setBounds(6, 277, 380, 255);
frame.getContentPane().add(canvasTemp);
Canvas canvasLevel = new Canvas();
canvasLevel.setBackground(SystemColor.window);
canvasLevel.setBounds(6, 10, 380, 255);
frame.getContentPane().add(canvasLevel);
}
public JFrame frame() {
return frame;
}
}
And here is the main file to get it running for you guys... :
Client.java
import java.io.IOException;
public class Client {
public static void main(String[] args) throws IOException, InterruptedException {
MyClientApp window = new MyClientApp(null, null);
window.frame.setVisible(true);
}
}
The code I want to implement is:

I'm sorry about the long code. Its just the samplecode from JavaFX. You find it here, and here.
That should be quite easy to solve. Let me explain it with the chart example that you've shown.
Add an instance of JFXPanel to your JFrame. In your examples, all components are added to a Stage, which is the JavaFX class to represent a window. So you don't need it here. Instead, you add the components that you want to use to the JFXPanel. See also here (function initAndShowGUI) how to do it.
In the init function of the example, a Scene is created as well as the chart itself. What you have to do to let the chart be shown is not much more than that - create a Scene, fill it with content and pass it to the JFXPanel that you already created.
With a minimum effort you can make your chart example run: Make sure that AdvancedLineChartSample.java is in your build path and that the function createChart is somehow accessible from your JFrame. Then add the chart to your code with something similar to the following snippet.
Group root=new Group();
Scene scene=new Scene(root);
myJFXPanel.setScene(scene);
root.getChildren().add(createChart());
This is just a very quick and dirty solution to run your example without any beautiful code and also I didn't test it. But hopefully it gives you a basic understanding of what's going on to encourage further experiments. By my own experience I can tell you that from this step on, there's a lot of fun to come with JavaFX 2.
