I have a problem with a Context menu in JavaFx 2:it never disappers when I left click on the graph of the JFXPanel
Does anybody knows how to solve this problem?
Thanks
Here is my code
final ContextMenu cm = new ContextMenu();
MenuItem chartItem1 = new MenuItem("Chart Settings");
cm.getItems().add(chartItem1);
getScene().setOnMouseReleased(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent mouseEvent) {
if(cm.isShowing()){
cm.hide();
}
if(mouseEvent.getButton() == MouseButton.SECONDARY)
{
cm.show(getScene().getRoot(), mouseEvent.getScreenX(), mouseEvent.getScreenY());
}
}
});
chartItem1.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent t) {
dialogs.ChartFormat cs = new dialogs.ChartFormat(null, true);
cs.setLocationRelativeTo(null);
cs.setVisible(true);
}
});
Reproduced the described behavior. Don't know the reason but you can use ContextMenu#hide():
final ContextMenu cm = new ContextMenu();
MenuItem menuItem = new MenuItem("Item 1");
menuItem.addEventHandler(EventType.ROOT, new EventHandler<Event>() {
#Override
public void handle(Event t) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
JPanel messagePane = new JPanel();
messagePane.add(new JLabel("label"));
JDialog jDialog = new JDialog();
jDialog.getContentPane().add(messagePane);
jDialog.pack();
jDialog.setVisible(true);
}
});
}
});
cm.getItems().add(menuItem);
scene.setOnMouseReleased(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent mouseEvent) {
// if(cm.isShowing())
cm.hide();
if (mouseEvent.getButton() == MouseButton.SECONDARY) {
cm.show(lineChart, mouseEvent.getScreenX(), mouseEvent.getScreenY());
}
}
});

Adding sample code to your question would be more descriptive.

Just use Collections.shuffle(list); in your getImages() function.

Here is my code. I am using scene builder. The code is not working.For first time it loads the hello1.html but in thread the hello2.html does not load.
public class TwavlController implements Initializable {
/**
* Initializes the controller class.
*/
#FXML public WebView webPane;
private Service<Void> back_thread;
private WebEngine engine;
#Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
engine = webPane.getEngine();
final String html_file = "hello1.html"; //HTML file to view in web view
URL urlHello = getClass().getResource(html_file);
engine.load(urlHello.toExternalForm());
run();
}
private File last_update,current;
public void run(){
back_thread = new Service<Void>() {
#Override
protected Task<Void> createTask() {
return new Task<Void>() {
#Override
protected Void call() throws Exception {
updateMessage("hello2.html");
return null;
}
};
}
};
engine.userAgentProperty().bind(back_thread.messageProperty());
back_thread.restart();
}
}
I'm not really clear what you're trying to do here, but I think maybe you are looking for
public void run(){
back_thread = new Service<Void>() {
#Override
protected Task<Void> createTask() {
return new Task<Void>() {
#Override
protected Void call() throws Exception {
Platform.runLater(() ->
engine.load(getClass().getResource("hello2.html").toExternalForm()));
return null;
}
};
}
};
back_thread.restart();
}
I am building a menu (file, view, help, etc.). For ex. in File you have upload and exit (both working fine). In help I have some topics: ACF, ARIMA, HoltWinter, the idea is when you chose one of these a text to be displayed in a GridPane. The problem is when you chose one, it displays its text, but it also locks the whole app and you can do nothing, except close the app.
This is a file chooser and it's working just fine:
MenuItem upload = new MenuItem("Upload");
upload.setOnAction(new EventHandler<ActionEvent>() {
public void handle(ActionEvent event) {
FileChooser fileChooser = new FileChooser();
fileChooser.setTitle("Open Resource File");
fileChooser.showOpenDialog(primaryStage);
}
});
And here is an event, which is blocking the app:
MenuItem acfH = new MenuItem("ACF");
acfH.setOnAction(new EventHandler<ActionEvent>(){
public void handle(ActionEvent event){
fr.md.pack.TextClass.acfText.setFill(Color.FIREBRICK);
fr.md.pack.TextClass.acfText.setText(fr.md.pack.StringClass.aboutACF);
grid.add(fr.md.pack.TextClass.acfText,1,10);
}
});
Any suggestions how to solve the issue?
Thanks in advance.

Well, I just installed Java 8 and surprise....everything is working just fine. I used till now Java 1.7 update 45 and it was locking my application as soon as I try to use the Action event. With Java 8 it's working but not without some bugs....
I have a FlowPane which use used as stage for many BorderPane components. I created Context menu for the BorderPane components. I want to add second context menu also for the FlowPane but it turns out that I now have two context menus when I click on BorderPane. I need a way to exclude the second context menu from the BorderPane.
FlowPane flow;

Is there a way to show makeTabContextMenu() only visible for the FlowPane body?
Have you tried to set the event consumed?
#Override

{
...
t.consume()
...
}
UPDATE:
My Requirement is to display two Rss files as Tabs on my LWUIT Form
Initially by default first Rss file titles and images should be displayed on first tab
if an end user click on second tab,we should be able to load the second rss file titles and images
I am able to load first Rss File titles,but i am not able to load the second tab if i click on it
How to capture the click event for LWUIT Tab?
Here my code which is not working:
String topNewsurl="TopNews.rss";
String topStoryurl="TopStory.rss";
public class XMLMidlet extends MIDlet{
public void startApp() {
Display.init(this);
Process p;
try {
p = new Process(this);
p.process();
} catch (IOException ex) {
ex.printStackTrace();
}
}
public class Process extends Form {
Process(XMLMidlet midlet) throws IOException {
this.midlet=midlet;
topnews = new Vector();
topstory = new Vector();
tabs = new Tabs();
form1 = new Form();
form2=new Form();
form1.setLayout(new BorderLayout());
form1.setScrollable(false);
image = Image.createImage("/res/Tone.jpg");
Label icon = new Label(image);
form1.setTitleComponent(icon);
form2.setTitleComponent(icon);
form1.setTransitionInAnimator(Transition3D.createRotation(250, true));
try {
newsList = new List(topnews);
newsList.setScrollVisible(false);
newsList.setRenderer(new NewsListCellRenderer());
myNewsList = new List(topstory);
myNewsList.setScrollVisible(false);
myNewsList.setRenderer(new NewsListCellRenderer());
tabs.addTab("Topstory", newsList);
tabs.addTab("TopNews", myNewsList);
tabs.setChangeTabOnFocus(true);
form1.addComponent(BorderLayout.CENTER, tabs);
}
try{
String url = "http:topnews-20.rss";
form1.show();
ParseThread myThread = new ParseThread(this);
myThread.getXMLFeed(url);
} catch (Exception e) {
e.printStackTrace();
}
}
public void addNews(News newsItem) {
//log.debug("addnews");
//System.out.println("addNews");
topnews.addElement(newsItem);
newsList.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
List source = (List) ae.getSource();
News selectedNewsItem = (News) source.getSelectedItem();
if (selectedNewsItem != null) {
displayCompleteNewsScreen(selectedNewsItem);
}
}
});
form1.show();
}
public void keyReleased(int keyCode) {
System.out.println("str");
Component p=this.getFocused();
String str= p.getClass().getName();
if(str.toLowerCase().indexOf("radiobutton")!=-1){
process();
}
From the very vague question it seems you want to capture key presses on a LWUIT Form.
jobsForm.addGameKeyListener(Display.GAME_FIRE,
new ActionListener() {
public void actionPerformed(ActionEvent evt) {
//do something here
}
});
jobsForm.addPointerPressedListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
pointer_click = true;
}
});
