I'm developing an app but when I try to getstatuscode of httprequest
in order to know Which of the gameend overlay to call the status code is called multiple times so how do I call it just once
public void update(float dt) {
for (NewPhysicsActor baseEnemyOthers: balloonList) {
if (baseEnemyOthers.getY() < 250) {
removeList.add(baseEnemyOthers);
gameFailed();
}
}
}
public void gameFailed() {
HttpRequest request = new HttpRequest(HttpMethods.GET);
request.setUrl("https://www.google.com");
Gdx.net.sendHttpRequest(request, new HttpResponseListener() {
#Override
public void handleHttpResponse(HttpResponse httpResponse) {
HttpStatus status = httpResponse.getStatus();
if (status.getStatusCode() >= 200 && status.getStatusCode() < 300) {
togglePaused();
watchVideoOverlay.setVisible(isPaused());
} else {
togglePaused();
levelFailedOverlay.setVisible(isPaused());
}
}
#Override
public void failed(Throwable t) {
togglePaused();
levelFailedOverlay.setVisible(isPaused());
}
#Override
public void cancelled() {
togglePaused();
levelFailedOverlay.setVisible(isPaused());
}
});
}
if I off my data connection everything works perfectly
but when it's on the problem continues. Watchoverlay() is called on and off continuously without stop

Greetings to the community. This is my first question, please guide me if I did any mistake.
I have four fragments in my app. An activity(Main Activity) that hosts all the four fragments.
Google Maps Fragment
Fragment two
Fragment three
Fragment four
When the application starts. Maps fragment is loaded and it shows marker at my current location. But when I move from Maps fragment to Fragment two and then came back to Map Fragment it doesn't show my current location
Here is the code
MainActivity.java
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
// Fragments
private MapsFragment mapsFragment = new MapsFragment();
private QrScanFragment qrScanFragment = new QrScanFragment();
private SeatsFullFragment seatsFullFragment = new SeatsFullFragment();
private EmergencyFragment emergencyFragment = new EmergencyFragment();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

initListeners();
// Maps Fragment Loaded
mIvMaps.setBackground(getResources().getDrawable(R.drawable.bg_tint_icon));
loadFragment(mapsFragment);
}
}
loadFragment(Fragment fragment)
public void loadFragment(Fragment fragment) {
if (fragment != null) {
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.frame_container, fragment)
.commit();
}
}
Moving b/w fragments
if (view == mLlMaps) {
if (!mapsFragment.isVisible()) {
loadFragment(mapsFragment);

I'm trying to use Topshelf Framework to create a windows service. But when i try to start the service, there is this exception :
" The service failed to start... System.Service.Process.TimeoutException : the waiting period has expired and the operation has not been completed"
This is my code :
public class MyService : ServiceControl
{
private System.Timers.Timer _timer;
public void MyService()
{
_timer = new System.Timers.Timer(10);
_timer.AutoReset = false;
_timer.Elapsed += new ElapsedEventHandler(TimerOnElapsed);
}
private void TimerOnElapsed(object source, ElapsedEventArgs e)
{
//all the operation to do at the startup
}
public bool Start(HostControl hostControl)
{
_timer.Start();
return true;
}
public bool Stop(HostControl hostControl)
{
_timer.Stop();
return true;
}
}
Thanks for any help :)
There are several issues I notice:
The current code would make the timer fire only once (you have AutoReset = false)
with TopShelf, the MyService class should look like this:
using System.Timers;
using Topshelf;
namespace TopShelfTestService
{
public class MyService
{
private System.Timers.Timer _timer;
public MyService()
{
_timer = new System.Timers.Timer(10);
_timer.AutoReset = true;
_timer.Elapsed += new ElapsedEventHandler(TimerOnElapsed);
}
private void TimerOnElapsed(object source, ElapsedEventArgs e)
{
//all the operation to do at the startup
}
public bool Start(HostControl hostControl)
{
_timer.Start();
return true;
}
public bool Stop(HostControl hostControl)
{
_timer.Stop();
return true;
}
}
}
and the console app/ Program.cs will look like so:
using Topshelf;
namespace TopShelfTestService
{
class Program
{
static void Main(string[] args)
{
HostFactory.Run(x =>
{
x.Service<MyService>(s =>
{
s.ConstructUsing(name => new MyService());
s.WhenStarted((tc, hostControl) => tc.Start(hostControl));
s.WhenStopped((tc, hostControl) => tc.Stop(hostControl));
});
x.RunAsLocalSystem();
x.SetDescription("Sample Topshelf Host"); //7
x.SetDisplayName("Test Service with TopShelf"); //8
x.SetServiceName("TopShelfTestService");
});
}
}
}
I want to create keyboard shortcuts in my application, for instance Ctrl+C for copy. Also I want to ignore that shortcut if a TextBox has focus.
First you need a way to check if control key is pressed. CoreWindow.GetKeyState will do the job but might be a little bit tricky to use so I created an helper class:
public class ModifierKeys
{
#region ShiftIsDown property
public static bool ShiftIsDown
{
get
{
return (Window.Current.CoreWindow.GetKeyState(VirtualKey.Shift) & CoreVirtualKeyStates.Down) != 0;
}
}
public static bool OnlyShiftIsDown
{
get
{
return ShiftIsDown && !AltIsDown && !ControlIsDown;
}
}
#endregion
#region AltIsDown property
public static bool AltIsDown
{
get
{
return (Window.Current.CoreWindow.GetKeyState(VirtualKey.Menu) & CoreVirtualKeyStates.Down) != 0;
}
}
public static bool OnlyAltIsDown
{
get
{
return !ShiftIsDown && AltIsDown && !ControlIsDown;
}
}
#endregion
#region ControlIsDown property
public static bool ControlIsDown
{
get
{
return (Window.Current.CoreWindow.GetKeyState(VirtualKey.Control) & CoreVirtualKeyStates.Down) != 0;
}
}
public static bool OnlyControlIsDown
{
get
{
return !ShiftIsDown && !AltIsDown && ControlIsDown;
}
}
#endregion
#region NoModifierKeyIsDown property
public static bool NoModifierKeyIsDown
{
get
{
return !ShiftIsDown && !AltIsDown && !ControlIsDown;
}
}
#endregion
}
Now in OnNavigateTo/From in your page subscribe/unsubscribe on key down events:
protected override void OnNavigatedTo(NavigationEventArgs e)
{
/*...*/
Window.Current.CoreWindow.KeyDown += CoreWindow_KeyDown;
}
protected override void OnNavigatedFrom(NavigationEventArgs e)
{
/*...*/
Window.Current.CoreWindow.KeyDown -= CoreWindow_KeyDown;
}
The CoreWindow_KeyDown will then looks something like this:
void CoreWindow_KeyDown(CoreWindow sender, KeyEventArgs args)
{
var focusedElement = FocusManager.GetFocusedElement();
if (args.KeyStatus.WasKeyDown == false && ModifierKeys.OnlyControlIsDown &&
!(focusedElement is TextBox)
)
{
if (args.VirtualKey == VirtualKey.X)
{
/*...cut...*/
}
else if (args.VirtualKey == VirtualKey.V)
{
/*...paste...*/
}
else if (args.VirtualKey == VirtualKey.C)
{
/*...copy...*/
}
}
}
I've made a simple Media Player for an application I'm working on, the problem is that I thought that you could simply integrate JavaFX into Swing. Which is not the case. I have been searching for a solution to this problem and tried to use this website: http://docs.oracle.com/javafx/2/swing/jfxpub-swing.htm
The problem is that even though I have the website that explains how to put the code together, I still don't understand how. Here is the mediaplayer and I plan to integrate it into my Swing code, so that I can call the media player when a button is clicked. Here is all my code for the media player and if anyone can share some light on how to integrate it into my Swing code i.e my GUI, I would probably have to kiss you through the computer.
public class Player extends Application{
private boolean atEndOfMedia = false;
private final boolean repeat = false;
private boolean stopRequested = false;
private Duration duration;
private Label playTime;
private Slider volumeSlider;
#Override
public void start(final Stage stage) throws Exception {
stage.setTitle("Movie Player");//set title
Group root = new Group();//Group for buttons etc
final Media media = new Media("file:///Users/Paul/Downloads/InBruges.mp4");
final MediaPlayer playa = new MediaPlayer(media);
MediaView view = new MediaView(playa);
//Slide in and out and what causes that.
final Timeline slideIn = new Timeline();
final Timeline slideOut = new Timeline();
root.setOnMouseEntered(new javafx.event.EventHandler<javafx.scene.input.MouseEvent>() {
#Override
public void handle(MouseEvent t) {
slideIn.play();
}
});
root.setOnMouseExited(new javafx.event.EventHandler<javafx.scene.input.MouseEvent>() {
#Override
public void handle(MouseEvent t) {
slideOut.play();
}
});
final VBox vbox = new VBox();
final Slider slider = new Slider();
final Button playButton = new Button("|>");
root.getChildren().add(view);
root.getChildren().add(vbox);
vbox.getChildren().add(slider);
vbox.getChildren().add(playButton);
vbox.setAlignment(Pos.CENTER);
Scene scene = new Scene(root, 400, 400, Color.BLACK);
stage.setScene(scene);
stage.show();
// Play/Pause Button
playButton.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent e) {
Status status = playa.getStatus();
if (status == Status.UNKNOWN || status == Status.HALTED)
{
// don't do anything in these states
return;
}
if ( status == Status.PAUSED
|| status == Status.READY
|| status == Status.STOPPED)
{
// rewind the movie if we're sitting at the end
if (atEndOfMedia) {
playa.seek(playa.getStartTime());
atEndOfMedia = false;
}
playa.play();
} else {
playa.pause();
}
}
});
//Listeners and Shit for Play Button
playa.setOnPlaying(new Runnable() {
#Override
public void run() {
if (stopRequested) {
playa.pause();
stopRequested = false;
} else {
playButton.setText("||");
}
}
});
playa.setOnPaused(new Runnable() {
#Override
public void run() {
playButton.setText(">");
}
});
playa.play();
playa.setOnReady(new Runnable() {
#Override
public void run(){
int v = playa.getMedia().getWidth();
int h = playa.getMedia().getHeight();
stage.setMinWidth(v);
stage.setMinHeight(h);
vbox.setMinSize(v, 100);
vbox.setTranslateY(h-50);
//slider and graphical slide in/out
slider.setMin(0.0);
slider.setValue(0.0);
slider.setMax(playa.getTotalDuration().toSeconds());
slideOut.getKeyFrames().addAll(
new KeyFrame(new Duration(0),
new KeyValue(vbox.translateYProperty(), h-100),
new KeyValue(vbox.opacityProperty(), 0.9)
),
new KeyFrame(new Duration(300),
new KeyValue(vbox.translateYProperty(), h),
new KeyValue(vbox.opacityProperty(), 0.0)
)
);
slideIn.getKeyFrames().addAll(
new KeyFrame(new Duration(0),
new KeyValue(vbox.translateYProperty(), h),
new KeyValue(vbox.opacityProperty(), 0.0)
),
new KeyFrame(new Duration(300),
new KeyValue(vbox.translateYProperty(), h-100),
new KeyValue(vbox.opacityProperty(), 0.9)
)
);
}
});
//Slider being current and ability to click on slider.
playa.currentTimeProperty().addListener(new ChangeListener<Duration>(){
#Override
public void changed(ObservableValue<? extends Duration> observableValue, Duration duration, Duration current){
slider.setValue(current.toSeconds());
}
});
slider.setOnMouseClicked(new javafx.event.EventHandler<javafx.scene.input.MouseEvent>() {
#Override
public void handle(javafx.scene.input.MouseEvent t) {
playa.seek(Duration.seconds(slider.getValue()));
}
});
}
Use JFXPanel:
public class Test {
private static void initAndShowGUI() {
// This method is invoked on Swing thread
JFrame frame = new JFrame("FX");
final JFXPanel fxPanel = new JFXPanel();
frame.add(fxPanel);
frame.setVisible(true);
Platform.runLater(new Runnable() {
#Override
public void run() {
initFX(fxPanel);
}
});
}
private static void initFX(JFXPanel fxPanel) {
// This method is invoked on JavaFX thread
Scene scene = createScene();
fxPanel.setScene(scene);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
initAndShowGUI();
}
});
}
}
where method createScene() is start(final Stage stage) from your code.
Just instead of putting scene to stage you return it.
I'm trying to set a documentFilter for my JTextArea. Having overriden the insert(...) method I admitted that it is never called. What's wrong? A piece of code:
package jaba;
import javax.swing.*;
import javax.swing.text.*;
import java.awt.*;
public class Main extends JFrame {
public Main() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(640, 480);
setLayout(new FlowLayout());
add(txt);
Document doc = txt.getDocument();
if (doc instanceof AbstractDocument) {
((AbstractDocument)doc).setDocumentFilter(new DocumentFilter() {
#Override
public void insertString(DocumentFilter.FilterBypass fb,
int offset, String string, AttributeSet att)
throws BadLocationException {
if (string.toLowerCase().contains("ass")) {
super.insertString(fb, offset, "###", att);
} else {
super.insertString(fb, offset, string, att);
}
}
});
} else {
txt.setText("error setting filter");
}
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
new Main().setVisible(true);
}
});
}
private JTextArea txt = new JTextArea(40, 40);
}
Having overriden the insert(...) method I admitted that it is never called.
Changes to the text in Swing components ultimately invoke the replace(...) method of the DocumentFilter.
The insertString(...) method is only invoked when you update the Document directly by using code like:
textField.getDocument().insertString(...);
So you need to make sure that you also override the replace() method in the DocumentFilter.
