I am writing a Java program that uses a Swing-based user interface, however I needed access to WebView, so I implemented a JFXPanel to take care of that. WebView is supposed to load an advertisement banner in to the program that the user can click on if the want. Currently, when the advertisement is clicked, the new page is loading within WebView. If possible, I would like to have the page open in the user's default browser and have the page containing the advertisement refresh. How can I achieve this?
engine.getLoadWorker().stateProperty().addListener(new ChangeListener<Worker.State>()
{
#Override
public void changed(ObservableValue<? extends Worker.State> observable, Worker.State oldValue,
Worker.State newValue)
{
String toBeopen =
engine.getLoadWorker().getMessage().trim();
System.out.println("tobeopen: " + toBeopen);
if (toBeopen.contains("http://") || toBeopen.contains("https://")) {
engine.getLoadWorker().cancel();
try {
Desktop.getDesktop().browse(new URL(toBeopen).toURI());
}
catch (MalformedURLException e) {
e.printStackTrace();
}
catch (URISyntaxException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
}
}
});

After updating to the latest Android Things preview, my app is crashing when
setting a callback on by button GPIO. I have the following button callback defined:
private class ButtonCallback extends GpioCallback {
#Override
public boolean onGpioEdge(Gpio gpio) {
boolean isPressed = false;
try {
isPressed = gpio.getValue();
} catch (IOException e) {
Log.w(TAG, "Error", e);
}
if (isPressed) {
...
}
return true;
}
}
I am registering it with the GPIO in the application as follows:
Gpio button = ...;
try {
button.registerGpioCallback(new ButtonCallback());
} catch (IOException e) {
Log.w(TAG, "Error configuring GPIO pins", e);
}
When I run my app, I get an IncompatibleClassChangeError and the app crashes:
java.lang.IncompatibleClassChangeError: Superclass com.google.android.things.pio.GpioCallback of com.google.android.things.example.MainActivity$ButtonCallback is an interface (...)
This code was working before, why has this started happening after the update?
Starting in Preview 7, many of the Peripheral I/O interfaces were converted from
abstract classes to interfaces. This was done to better facilitate testability
in apps, as interfaces are easier to mock.
Be sure to update your app to use the Preview 7 SDK:
dependencies {
compileOnly 'com.google.android.things:androidthings:0.7-devpreview'
}
Then modify your callback to implement the interface instead:
private class ButtonCallback implements GpioCallback {
#Override
public boolean onGpioEdge(Gpio gpio) {
boolean isPressed = false;
try {
isPressed = gpio.getValue();
} catch (IOException e) {
Log.w(TAG, "Error", e);
}
if (isPressed) {
...
}
return true;
}
}
Review the Android Things API reference
to verify if any of the other APIs you are calling have changed.
I am developing Umbraco 7 MVC application and my requirement is to add Item inside Umbraco. Item name should be unique. For that used the below code but I am getting the error "Oops: this document is published but is not in the cache (internal error)"
protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication,
ApplicationContext applicationContext)
{
ContentService.Publishing += ContentService_Publishing;
}
private void ContentService_Publishing(IPublishingStrategy sender, PublishEventArgs<IContent> e)
{
try
{
if(newsItemExists)
{
e.Cancel = true;
}
}
catch (Exception ex)
{
e.Cancel = true;
Logger.Error(ex.ToString());
}
}
Then I tried adding code to unpublish but its not working i.e the node is getting published. Below is my code
private void ContentService_Publishing(IPublishingStrategy sender, PublishEventArgs<IContent> e)
{
try
{
int itemId=1234; //CurrentPublishedNodeId
if(newsItemExists)
{
IContent content = ContentService.GetById(itemId);
ContentService.UnPublish(content);
library.UpdateDocumentCache(item.Id);
}
}
catch (Exception ex)
{
e.Cancel = true;
Logger.Error(ex.ToString());
}
}
But with the above code, if you give the CurrentPublishedNodeId=2345 //someOthernodeId its unpublished correctly.
Can you please help me on this issue.
You don't have to do this, Umbraco will automatically append (1) to the name if the item already exists (so it IS unique).
If you don't want this behavior you can check in the following way:
protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
{
ContentService.Publishing += ContentService_Publishing;
}
private void ContentService_Publishing(Umbraco.Core.Publishing.IPublishingStrategy sender, PublishEventArgs<IContent> e)
{
var contentService = UmbracoContext.Current.Application.Services.ContentService;
// It's posible to batch publish items, so go through all items
// even though there might only be one in the list of PublishedEntities
foreach (var item in e.PublishedEntities)
{
var currentPage = contentService.GetById(item.Id);
// Go to the current page's parent and loop through all of it's children
// That way you can determine if any page that is on the same level as the
// page you're trying to publish has the same name
foreach (var contentItem in currentPage.Parent().Children())
{
if (string.Equals(contentItem.Name.Trim(), currentPage.Name.Trim(), StringComparison.InvariantCultureIgnoreCase))
e.Cancel = true;
}
}
}
I think your problem might be that you're not looping through all PublishedEntities but using some other way to determine the current page Id.
Note: Please please please do not use the library.UpdateDocumentCache this, there's absolutely no need, ContentService.UnPublish will take care of the cache state.
a simple MessageDialog(or MessageBox,any method can open a dialog )like follows:
MessageDialog.openInformation(shell, "Test", "Get help form this link www.google.com");
is there any way to make www.google.com a hyperlink? click the url and open browser.
thats not possible out of the box. I created a class of my own, named MyMessageDialog to do this:
https://gist.github.com/andydunkel/8914008
Its basically all the source code from MessageDialog. Then I overwrote the createMessageArea method and added a Link instead of a label and added an event listener:
protected Control createMessageArea(Composite composite) {
// create composite
// create image
Image image = getImage();
if (image != null) {
imageLabel = new Label(composite, SWT.NULL);
image.setBackground(imageLabel.getBackground());
imageLabel.setImage(image);
//addAccessibleListeners(imageLabel, image);
GridDataFactory.fillDefaults().align(SWT.CENTER, SWT.BEGINNING)
.applyTo(imageLabel);
}
// create message
if (message != null) {
linkLabel = new Link(composite, getMessageLabelStyle());
linkLabel.setText(message);
linkLabel.addSelectionListener(new SelectionAdapter(){
#Override
public void widgetSelected(SelectionEvent e) {
System.out.println("You have selected: "+e.text);
try {
// Open default external browser
PlatformUI.getWorkbench().getBrowserSupport().getExternalBrowser().openURL(new URL(e.text));
}
catch (PartInitException ex) {
// TODO Auto-generated catch block
ex.printStackTrace();
}
catch (MalformedURLException ex) {
// TODO Auto-generated catch block
ex.printStackTrace();
}
}
});
GridDataFactory
.fillDefaults()
.align(SWT.FILL, SWT.BEGINNING)
.grab(true, false)
.hint(
convertHorizontalDLUsToPixels(IDialogConstants.MINIMUM_MESSAGE_AREA_WIDTH),
SWT.DEFAULT).applyTo(linkLabel);
}
return composite;
}
The MessageDialog can be called with HTML code in it now:
MyMessageDialog.openError(parent.getShell(), "Hehe", "Google.com Test");
Not a very optimal solution, but it works:

});
}

I'm using the blackberry torch 9800 simulator and hardware device for testing.
In the simulator I cannot retrieve the data over wifi, even though the connection to wifi is found. It works when the mobile network is enabled.
Now, when I replace my web service with the Twitter api, I get the data regardless of transport type. I tried adding ;deviceside=false to my url, but nothing. It's not https or anything.
I just want my web service accessed! I know nothing about this mds,bis,bes,bis_b junk.
EDIT:
Jeez. I'm realizing it may be my site. Not using the web service and just retrieving the page, www.example.com, I get nothing. But, google.com or any other site I use retrieves the html. Am I missing headers!?!
Try appending ;interface=wifi to the end of your URL, this will force the simulator to use your simulated Wi-Fi connection, which is your PC's network connection.
You will need to have setup Wi-Fi on the simulator by going to Manage Connections->Set Up Wi-Fi Network, then connect to Default WLAN Network.
I want to Implement a QR Code Reader In BlackBerry Os 6. I try the following Code On the Basis of KB Article How to use the Barcode API.
public class ScanScreen extends MainScreen implements BarcodeDecoderListener
{
private LabelField match;
private BarcodeScanner scanner;
public ScanScreen()
{
match = new LabelField("Scanning...");
add(match);
Vector supported = new Vector();
supported.addElement(BarcodeFormat.QR_CODE);
Hashtable hints = new Hashtable();
hints.put(DecodeHintType.POSSIBLE_FORMATS, supported);
hints.put(DecodeHintType.TRY_HARDER, Boolean.TRUE);
BarcodeDecoder decoder = new BarcodeDecoder(hints);
try
{
scanner = new BarcodeScanner(decoder, this);
add(scanner.getViewfinder());
scanner.startScan();
}
catch (Exception e)
{
e.printStackTrace();
match.setText("Exception");
invalidate();
}
}
public void barcodeDecoded(String rawText)
{
match.setText("Found: " + rawText);
invalidate();
}
public void close()
{
try
{
scanner.stopScan();
}
catch (Exception e)
{
e.printStackTrace();
}
super.close();
}
}
The Code not working. It do not recognize QR codes. I try to focus on different QR codes. But it not decode The qrcodes.Also It not Thrown Any exceptions. Please Help me....
I tried using these Devices: BB pearl 9105 and BB Storm 9530
See the sample from the following link.It will help you
http://aliirawan-wen.blogspot.com/2011/05/barcode-scanner-for-blackberry-os-50.html
I'm painfully new to BB development, but I notice you pass "this" as the decoderlistener parameter, perhaps that's causing a problem?
BarcodeDecoder decoder = new BarcodeDecoder(hints);
BarcodeDecoderListener decoderListener = new BarcodeDecoderListener()
{
public void barcodeDecoded(String rawText)
{
displayMessage(rawText);
}
};
try
{
scanner = new BarcodeScanner(decoder, decoderListener)
add(scanner.getViewfinder());
scanner.startScan();
}
catch (Exception e)
{
e.printStackTrace();
match.setText("Exception");
invalidate();
}
}
