A couple of weeks ago, i used NetBeans to create one of it's javafx examples
The webview project, and it worked fine.
I am especially interested in using javafx to play youtube videos
in a swinginterop application.
This is part of a bigger project, so i used the SwingInterop example from NetBeans to load the players on a JFrame
I need to load more than one YouTube Video.
And again everything worked great.
I am using Windows XP, NetBeans 7.2, Java 1.7 9
These days i tried the application again but this time on youtube i see
"This Video is currently unavailable".
The first thing that came into my mind was that maybe
i don't have the latest FlashPlayer ...
Needless to say i downloaded everything...
The application just won't play youtube videos anymore
I even reinstalled java and netbeans again but nothing changed.
I also mention that on Firefox, which is the browser i have on my pc
youtube works just fine.
It is pretty annoying to know that ... something was ok and maybe ...
i found a way to mess things in there ...
So right now, i can see web pages in javafx webview but youtube videos are still not playing...
The last time i asked for help i did not put the code ... sorry about that.
So i made another small project with only two classes in it to show what i did
I did not test this on another pc because, if it happened once
chances are it will happen again and since things don't fix themselves
i want to be able to answer this question when it will pop up.
Thank you jewelsea and Gregory for the interest
here is the code :

I am trying to create a table in javafx that allows a user to click on a row to go to one page or double click the row to go to a different page. The problem is that the application registers the event of the single click, but does not wait to see if there is another double click. Is there a way to have the program wait and see if there is another click?
what i have so far looks similar to something like
TableView searchResults;
ObservableList<MovieRow> rows = FXCollections.observableArrayList();
private TableColumn<MovieRow, String> title;
title.setCellValueFactory(new PropertyValueFactory<>("mTitle"));
rows.add(new MovieRow("The cat in the hat"));
searchResults.setItems(rows);
searchResults.setRowFactory(tv -> {
TableRow<MovieRow> row = new TableRow<>();
row.setOnMouseClicked(event -> {
MovieRow tempResult = row.getItem();
if (event.getClickCount() == 1) {
System.out.println(tempResult.getMTitle + " was clicked once");
}else{
System.out.println(tempResult.getMTitle + " was clicked twice");
}
});
return row;
});
public class MovieRow{
private String mTitle;
public MovieRow(String title){
mTitle = title;
}
public String getMTitle() {
return mTitle;
}
}
actual output
single click: The cat in the hat was clicked once
double click: The cat in the hat was clicked once
desired output
single click: The cat in the hat was clicked once
double click: The cat in the hat was clicked twice
I've only found results on handling double clicks by themselves or single clicks by themselves but not having both, so I'm not sure if this is even possible. Any help would be much appreciated. Thanks.
There's no way to do this that's part of the API: you just have to code "have the program wait and see if there is another click" yourself. Note that this means that the single-click action has to have a slight pause before it's executed; there's no way around this (your program can't know what's going to happen in the future). You might consider a different approach (e.g. left button versus right button) to avoid this slightly inconvenient user experience.
However, a solution could look something like this:
public class DoubleClickHandler {
private final PauseTransition delay ;
private final Runnable onSingleClick ;
private final Runnable onDoubleClick ;
private boolean alreadyClickedOnce ;
public DoubleClickHandler(
Duration maxTimeBetweenClicks,
Runnable onSingleClick,
Runnable onDoubleClick) {
alreadyClickedOnce = false ;
this.onSingleClick = onSingleClick ;
this.onDoubleClick = onDoubleClick ;
delay = new PauseTransition(maxTimeBetweenClicks);
delay.setOnFinished(e -> {
alreadyClickedOnce = false ;
onSingleClick.run()
});
}
public void applyToNode(Node node) {
node.setOnMouseClicked(e -> {
delay.stop();
if (alreadyClickedOnce) {
alreadyClickedOnce = false ;
onDoubleClick.run();
} else {
alreadyClickedOnce = true ;
delay.playFromStart();
}
});
}
}
Which you can use with:
searchResults.setRowFactory(tv -> {
TableRow<MovieRow> row = new TableRow<>();
DoubleClickHandler handler = new DoubleClickHandler(
Duration.millis(500),
() -> {
MovieRow tempResult = row.getItem();
System.out.println(tempResult.getMTitle + " was clicked once");
},
() -> {
MovieRow tempResult = row.getItem();
System.out.println(tempResult.getMTitle + " was clicked twice");
}
);
handler.applyToNode(row);
return row ;
});
I encountered the same requirement once and worked on developing a custom event dispatcher. The solution what #James_D provided is clean, simple and works great. But if you want to generalize this behavior on a large scale, you can define a new custom mouse event and an event dispatcher.
The advantage of this approach is its usage will be just like other mouse events and can be handled in both event filters and handlers.

I am using a controlsfx GridView in a JavaFX application. It shows a scrollbar when needed, but I can't find any way to determine where the scrollbar is positioned at, nor update it. I need to be able to do things like respond to a "go to the top" command from the user and scroll up; or scroll to keep the selected thumbnail visible as the user uses arrow keys to navigate through the grid. But I don't see how to get access to the current scroll position, nor manipulate it, as you can with a ScrollPane.
For example, here is a sample application that creates a GridView with 100 generated images in it. I add a listener to the "onScrollProperty", but it is never called. I also have no idea how I would cause it to scroll to a certain scroll position (0..1):
import java.awt.image.BufferedImage;
import javafx.application.Application;
import javafx.application.Platform;
import javafx.embed.swing.SwingFXUtils;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.stage.Stage;
import org.controlsfx.control.GridView;
import org.controlsfx.control.cell.ImageGridCell;
// Demo class to illustrate the slowdown problem without worrying about thumbnail generation or fetching.
public class GridViewDemo extends Application {
private static final int CELL_SIZE = 200;
public static void main(String[] args) {
launch(args);
}
public void start(Stage primaryStage) {
// Create a Scene with a ScrollPane that contains a TilePane.
GridView<Image> gridView = new GridView<>();
gridView.setCellFactory(gridView1 -> new ImageGridCell());
gridView.setCellWidth(CELL_SIZE);
gridView.setCellHeight(CELL_SIZE);
gridView.setHorizontalCellSpacing(10);
gridView.setVerticalCellSpacing(10);
addImagesToGrid(gridView);
gridView.onScrollProperty().addListener((observable, oldValue, newValue) -> {
// Never called
System.out.println("Scrolled...");
});
primaryStage.setScene(new Scene(gridView, 1000, 600));
primaryStage.setOnCloseRequest(x -> {
Platform.exit();
System.exit(0);
});
primaryStage.show();
}
private void addImagesToGrid(GridView<Image> gridView) {
for (int i = 0; i < 100; i++) {
final Image image = createFakeImage(i, CELL_SIZE);
gridView.getItems().add(image);
}
}
// Create an image with a bunch of rectangles in it just to have something to display.
private static Image createFakeImage(int imageIndex, int size) {
BufferedImage image = new BufferedImage(size, size, BufferedImage.TYPE_INT_RGB);
Graphics g = image.getGraphics();
for (int i = 1; i < size; i ++) {
g.setColor(new Color(i * imageIndex % 256, i * 2 * (imageIndex + 40) % 256, i * 3 * (imageIndex + 60) % 256));
g.drawRect(i, i, size - i * 2, size - i * 2);
}
return SwingFXUtils.toFXImage(image, null);
}
}

Here is a screen shot of what it looks like.
Maybe to late for the questioner. But after i stumbled across the same problem, after hours of investigation, hopefully useful to others...
I add a listener to the "onScrollProperty", but it is never called.
This "works as intended". :-/ See https://bugs.openjdk.java.net/browse/JDK-8096847.
You have to use "addEventFilter()". See example below.
To set the scroll position is a pain. You have to get the underlying "VirtualFlow" object of the GridView. VirtualFlow contains methods to set the scroll position to specific rows. It's strange that GridView seems to have no API for this common use case. :-(
A "prove of concept" example how to set scroll position, for a GridView with images:
/**
* Register a scroll event and a key event listener to gridView.
* After that navigate with "arrow up" and "arrow down" the grid.
* #param gridView
*/
private void addScrollAndKeyhandler(final GridView<Image> gridView) {
// example for scroll listener
gridView.addEventFilter(ScrollEvent.ANY, e-> System.out.println("*** scroll event fired ***"));
// add UP and DOWN arrow key listener, to set scroll position
gridView.addEventHandler(KeyEvent.KEY_PRESSED, e -> {
if (e.getCode() == KeyCode.UP) oneRowUp(gridView);
if (e.getCode() == KeyCode.DOWN) oneRowDown(gridView);
});
}
int selectedRow = 0; // current "selected" GridView row.
/**
* Scrolls the GridView one row up.
* #param gridView
*/
private void oneRowUp(final GridView<Image> gridView) {
// get the underlying VirtualFlow object
VirtualFlow<?> flow = (VirtualFlow<?>) ((GridViewSkin<?>) gridView.getSkin()).getChildren().get(0);
if (flow.getCellCount() == 0) return; // check that rows exist
if (--selectedRow < 0) selectedRow = 0;
if (selectedRow >= flow.cellCountProperty().get()) selectedRow = flow.getCellCount() - 1;
System.out.println("*** KeyEvent oneRowUp " + selectedRow + " ***");
flow.scrollTo(selectedRow);
}
/**
* Scrolls the GridView one row down.
* #param gridView
*/
private void oneRowDown(final GridView<Image> gridView) {
// get the underlying VirtualFlow object
VirtualFlow<?> flow = (VirtualFlow<?>) ((GridViewSkin<?>) gridView.getSkin()).getChildren().get(0);
if (flow.getCellCount() == 0) return; // check that rows exist
if (++selectedRow >= flow.cellCountProperty().get()) selectedRow = flow.getCellCount() - 1;
System.out.println("*** KeyEvent oneRowDown " + selectedRow + " ***");
flow.scrollTo(selectedRow);
}

I have List<MediaPlayer> that is populating by
private List<MediaPlayer> players() {
for (String file : path.list((dir1, name) -> {
if (name.endsWith(SUPPORTED_VIDEO_FILE_EXTENSIONS)){
return true;
}
return false;
})) {
players.add(createPlayer(Paths.get(path + "/" + file).toUri().toString()));
System.out.println(Paths.get(path + "/" + file).toUri().toString());
}
return players;
}
In my case size of List<MediaPlayer> is 3. Than i use it there
if (currentNumOfVideo == -1) {
currentNumOfVideo = 0;
}
mv = new MediaView();
MediaPlayer currentPlayer = players.get(currentNumOfVideo);
mv.setMediaPlayer(currentPlayer);
currentPlayer.play();
players.get(currentNumOfVideo).setOnEndOfMedia(() -> {
players.get(currentNumOfVideo).stop();
if (currentNumOfVideo < players.size()) {
currentNumOfVideo += 1;
mv.setMediaPlayer(players.get(currentNumOfVideo));
players.get(currentNumOfVideo).play();
} else {
currentNumOfVideo = 0;
mv.setMediaPlayer(players.get(currentNumOfVideo));
players.get(currentNumOfVideo).play();
}
});
First video playing, when it ends second video starts. After second video MediaPlayer stops and didn't play third video.
I understand that because of my setOnEndOfMedia that is only on first MediaPlayer. When the second video starts it doesn't have setOnEndOfMedia. How can I setOnEndOfMedia on every video in my List<MediaPlayer>.
Personally, I would not create all the MediaPlayer instances ahead-of-time. Instead, get a list of Media objects or at least the URIs pointing to the media. Then create a method which is responsible for playing the next video when the current video ends. That method will dispose the old MediaPlayer, create the next MediaPlayer, and configure it to call the same method upon completion. For example:
import java.util.List;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javafx.stage.Stage;
public class Main extends Application {
private MediaView mediaView;
private List<Media> media;
private int curIndex;
#Override
public void start(Stage primaryStage) throws Exception {
media = ...; // get media from somewhere
mediaView = new MediaView();
primaryStage.setScene(new Scene(new StackPane(mediaView), 720, 480));
primaryStage.show();
playNextVideo();
}
private void playNextVideo() {
disposePlayer();
if (curIndex == media.size()) {
return; // no more videos to play
}
MediaPlayer player = new MediaPlayer(media.get(curIndex++));
player.setAutoPlay(true); // play ASAP
player.setOnEndOfMedia(this::playNextVideo); // play next video when this one ends
mediaView.setMediaPlayer(player);
}
private void disposePlayer() {
MediaPlayer player = mediaView.getMediaPlayer();
if (player != null) {
player.dispose(); // release resources
}
}
}
This may cause a pause between videos. If that's not acceptable you could create the next MediaPlayer ahead-of-time, either at the same time as the current MediaPlayer or when the current player reaches a certain timestamp (e.g. 10 seconds before the end). But I still wouldn't create all the MediaPlayer instances ahead-of-time.
i trying to use jquery.AreYouSure into JxBrowser(5.2 and/or next version).
jquery.AreYouSure works... but the warning pop up windows is always in english...
This behaviour is wrong and differ from chrome/firox/ie.... these show message in the current language...
this is a demo url

By default, JxBrowser displays dialogs configured with English language. At the same time, JxBrowser API provides functionality that allows modifying default behavior and display your own dialogs with required language. To change the language you need to register your own DialogHandler where you can display your own dialog. For example:

I get this error java.lang.ClassCastException: android.widget.LinearLayout cannot be cast to android.support.v4.app.Fragment when I try to open my activity CuteCollection.java in my app. The strange part is that when I click on the first line (FragmentPagerAdapter.java:122) in the logcat error, it shows me a line from a file in the v4.support library. I cannot edit that code, so there must be something in my code I can change.
To get to this activity, I click a button in my HomeFragment.java fragment, which is a fragment in my navigation drawer, which also has the android.support.v4.app.Fragment extension, just like all items do in my navigation drawer.
I think it might be something to do with my FragmentPagerAdpater. Although I did change all of my android.app.Fragment to android.support.v4.app.Fragment, but still the same error.
UPDATE: When I click on the first line in the support.v4 library, called FragmentPagerAdapter, it brings up that class and shows Fragment fragment = (Fragment)object; highlighted, which is part of this method (although I can't edit this, since it's from Android):
#Override
public void setPrimaryItem(ViewGroup container, int position, Object object) {
Fragment fragment = (Fragment)object;
if (fragment != mCurrentPrimaryItem) {
if (mCurrentPrimaryItem != null) {
mCurrentPrimaryItem.setMenuVisibility(false);
mCurrentPrimaryItem.setUserVisibleHint(false);
}
if (fragment != null) {
fragment.setMenuVisibility(true);
fragment.setUserVisibleHint(true);
}
mCurrentPrimaryItem = fragment;
}
}
Any tips or advice? Thanks.

Your current code seems to run into trouble unless you fix the Exception error. There is a working sample code from Google, and this is quite similar to your code design and meets your vision. I have tried it, and it works. Link at SlidingTabsBasic . One warning is that you will have to change your Gradle build file. If you choose this route, then I can post my build file.
Another similar sample on the same webpage is SlidingTabsColors, which sounds good since I end up in customizing colors for any GUI I make. The SDKs are possibly available on your local drive if you installed it.
If you decide on this route, just accept it as best answer, and post whatever issues you may come up with. At least, I know the sample code works.
Just to let you know, there is an interesting reading at Creating Swipe Views with Tabs, which meets your vision also, and the code seems simpler than what I recommend above. But...it uses ActionBar.TabListener which is deprecated for Lollipop, API version 21. Your choice...
There may be 2 different solutions/parts.
Part 1)
In your posted Java file, do this:
import android.support.v4.app.Fragment ;
remove or comment out:
import android.app.Fragment;
The reason is you are using android.support.v4.app.Fragment. And this is not compatible with your current import android.app.Fragment. Also all your imports reference android.support.v4, so you know you should do it anyway to be consistent :-)
Unfortunately the compiler does not detect this incompatibility.
Part 2)
Since you're using ActionBarActivity, there may be an issue with the build file or settings. The problem is confirmed by others in Stackoverflow # ActionBarActivity cannot resolve a symbol and Error inflating class from library. I know your error sounds different but I think the problem may be the same. Basically you can check your build gradle file (assuming you're using it):
dependencies {
compile "com.android.support:support-v4:21.0.2"
}
The idea is to use compile "com.android.support:support-v4..."
