  • JavaFX InternalFrame or WindowNode

    - by user1493549
    I was looking for an InternalFrame for JavaFX. Apparently I it seems like there is no InternalFrame available. How does one create an MDI application with JavaFX? I have tried to simulate this behavior by using a custom Region that can be dragged around. Is that the way to go? What about typical window elements such as titlebar, possibility to resize etc. Do I have to implement that myself via custom controls? Thanks, miho

  • How to copy a subset from an array of strings to an array of ints using Groovy?

    - by Cuga
    I have a String array in a Groovy class (args to a main method): String[] args I'd like to convert the 3rd to the last element into a new array of ints. Is there an easier way to do this in Groovy other than: final int numInts = args.length - 2 final int [] intArray = new int[numInts] for (int i = 2; i < args.length; i++) { intArray[i-2]=Integer.parseInt(args[i]) } I wanted to do: final int numInts = args.length - 2 final int [] intArray = new int[numInts] System.arraycopy(args, 2, intArray, 0, numInts) But it throws a class cast exception. Thanks!

  • How to avoid StaleObjectStateException when transaction updates thousands of entities?

    - by ThinkFloyd
    We are using Hibernate 3.6.0.Final with JPA 2 and Spring 3.0.5 for a large scale enterprise application running on tomcat 7 and MySQL 5.5. Most of the transactions in application, lives for less than a second and update 5-10 entities but in some use cases we need to update more than 10-20K entities in single transaction, which takes few minutes and hence more than 70% of times such transaction fails with StaleObjectStateException because some of those entities got updated by some other transaction. We generally maintain version column in all tables and in case of StaleObjectStateException we generally retry but since these longs transactions are anyways very long so if we keep on retrying then also I am not very sure that we'll be able to escape StaleObjectStateException. Also lot of activities keep updating these entities in busy hours so we cannot go with pessimistic approach because it can potentially halt many activities in system. Please suggest how to fix such long transaction issue because we cannot spawn thousands of independent and small transactions because we cannot afford messed up data in case of some failed & some successful transactions.

  • Customizing TabWidget in SDK 1.5, API 3

    - by Dylan McClung
    I'm aware that API 3 doesn't allow a view to be set for a tab, but I still need to modify the TextView displayed as the indicator. I'd also like to change the Drawable for the tab, but I don't see a way to do it without a custom tab view as allowed in 1.6, API 4. Working with this generic example below, is there way to retrieve the TextView and modify its properties or change the drawable? TabHost tabHost = getTabHost(); TabHost.TabSpec spec; spec = tabHost.newTabSpec("nearby") .setIndicator("Nearby Activity") .setContent(R.id.nearby_list); tabHost.addTab(spec); spec = tabHost.newTabSpec("friends") .setIndicator("Friends & Favorites") .setContent(R.id.friends_list); tabHost.addTab(spec); tabHost.setCurrentTabByTag("nearby"); Thanks for any help.

  • How to find a particular string in a paragraph in android?

    - by user1448108
    In my project the data is stored in html format along with image tag. For example the following data is stored in html format and it contains 2 to 3 images. Mother Teresa as she is commonly known, was born Agnes Gonxha Bojaxhiu. Although born on the 26 August 1910, she considered 27 August, the day she was baptized, to be her "true birthday". “By blood, I am Albanian. By citizenship, an Indian. By faith, I am a Catholic nun. As to my calling, I belong to the world. As to my heart, I belong entirely to the Heart of Jesus." img ----- src="image1.png" ---- Mother Teresa founded the Missionaries of Charity, a Roman Catholic religious congregation, which in 2012 consisted of over 4,500 sisters and is active in 133 countries.img ----- src="image2.png" ----. She was the recipient of numerous honours including the 1979 Nobel Peace Prize. She refused the conventional ceremonial banquet given to laureates, and asked that the $192,000 funds be given to the poor in India. img ----- src="image3.png" ---- Now from the above data I need to find how many images the paragraph has and need to get all the image names along with the extensions and should display them in android. Tried with splitting but did not work. Please help me regarding this. Thanks in advance

  • Changing order of locations on classpath to be leaded by surefire-plugin

    - by lisak
    Hey folks, does anybody know how to change it ? I mean from target/test-classes ... target/classes .... maven dependencies to target/test-classes ... maven dependencies .... target/classes It relates to this surefire-plugin feature request It's because surefire-plugin cannot exclude resources from /target/classes ... it can only modify resources via <testResources> element that modifies /target/test-classes

  • Android - Memory leak when dynamically building UI with image resource backgrounds

    - by Rich
    I have an Activity that I swear is leaking memory. The app I'm working on does a lot with images, so I've had to be pretty stingy with memory when working directly with Bitmaps. I added an Activity, and now if you use this new Activity it basically puts me over the edge with mem usage and I end up throwing the "Bitmap exceeds VM budget" exception. If you never launch this Activity, everything is smooth as it was previously. I started reading about memory leaks, and I think that I have a similar situation to what is described in the article in the Android docs. I'm dynamically creating a bunch of image views and adding a BackgroundDrawable from the resources and adding an OnClickListener as well. I imagine I have to do some cleanup when the Activity hits onPause in its life cycle, but I'd like to know specifically what is the correct way. Here is the code that should demonstrate the objects I'm working with... LinearLayout templateContainer; . . . ImageView imgTemplatePreview = (ImageView) item.findViewById(R.id.imgTemplatePreview); . . . imgTemplatePreview.setBackgroundDrawable(getResources().getDrawable(previewId)); imgTemplatePreview.setOnClickListener(imgClick); templateContainer.addView(item);

  • Share Link - Perform action in background

    - by Justin
    I have an application that will accept URLs from the built in web browser via the "Share page" menu item. I'm using the send intent and it works just fine. However, I'd like to accept a URL and process it in the background without bringing my application to the front. I don't want the user to have to actually leave the web browser. It will notify the user it has finished processing the URL with a Toast message. I'm just not sure what type of activity should be used for this. A good example of this behavior is the "Read Later" instapaper application in the android market. Any help would be greatly appreciated.

  • How do I pass an ArrayList to method that takes a collection as an input

    - by Ankur
    I want to pass some ArrayList X into method a(Collection someCol) that takes Collection as an input. How can I do this? I thought an ArrayList was a Collection and thus I should be able to "just do it" but it seems that Collection is an interface and ArrayList implements this interface. Is there something I can do to make this work ... if you understand the theory that would also help me and possibly lots of other people. Thanks

  • controlling the order of submitted futures

    - by mac
    In this example, i am submitting a few files to my comparator object. It all works fine, except that i noticed that order in which files are submitted is not always teh same order in which they are returned. Any suggestions on how i can better control this? ExecutorService pool = Executors.newFixedThreadPool(5); CompletionService<Properties> completion = new ExecutorCompletionService<Properties>(pool); for (String target : p.getTargetFiles()) { completion.submit(new PropertiesLoader(target, p)); } for (@SuppressWarnings("unused") String target : p.getTargetFiles()) { Properties r = null; try { r = completion.take().get(); } catch (InterruptedException e) { e.printStackTrace(); } catch (ExecutionException e) { e.printStackTrace(); } p.addTargetFilesProperties(r); } pool.shutdown();

  • Mutable objects and hashCode

    - by robert
    Have the following class: public class Member { private int x; private long y; private double d; public Member(int x, long y, double d) { this.x = x; this.y = y; this.d = d; } @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + x; result = (int) (prime * result + y); result = (int) (prime * result + Double.doubleToLongBits(d)); return result; } @Override public boolean equals(Object obj) { if (this == obj) { return true; } if (obj instanceof Member) { Member other = (Member) obj; return other.x == x && other.y == y && Double.compare(d, other.d) == 0; } return false; } public static void main(String[] args) { Set<Member> test = new HashSet<Member>(); Member b = new Member(1, 2, 3); test.add(b); System.out.println(b.hashCode()); b.x = 0; System.out.println(b.hashCode()); Member first = test.iterator().next(); System.out.println(test.contains(first)); System.out.println(b.equals(first)); System.out.println(test.add(first)); } } It produces the following results: 30814 29853 false true true Because the hashCode depends of the state of the object it can no longer by retrieved properly, so the check for containment fails. The HashSet in no longer working properly. A solution would be to make Member immutable, but is that the only solution? Should all classes added to HashSets be immutable? Is there any other way to handle the situation? Regards.

  • PreparedStatement and setTimestamp in oracle jdbc

    - by Roman
    Hi everyone, I am using PreparedStatement with Timestamp in where clause: PreparedStatement s=c.prepareStatement("select utctimestamp from t where utctimestamp>=? and utctimestamp<?"); s.setTimestamp(1, new Timestamp(1273017600000L)); //2010-05-05 00:00 GMT s.setTimestamp(2, new Timestamp(1273104000000L)); //2010-05-06 00:00 GMT The result I get is different, when I have different time zones on the client computer. Is this a bug in Oracle jdbc? or correct behavior? The parameter is Timestamp, and I expected that no time conversions will be done on the way. The database column type is DATE, but I also checked it with TIMESTAMP column type with the same results. Is there a way to achieve correct result? I cannot change default timezone in the the whole application to UTC. Thanks for your help

  • Line by line image swing

    - by user1046017
    I want to show an image as it is downloading, I have the URL, and I am trying to get the image parts like this: InputStream openStream = url.openStream(); DataInputStream dis = new DataInputStream(new BufferedInputStream(openStream)); ByteArrayOutputStream os = new ByteArrayOutputStream(); while ((s = dis.read(b)) != -1) { os.write(b , 0, s); support.firePropertyChange("stream", null, os); } This way, any listener get the stream and creates an image, this way: if("stream".equals(evt.getPropertyName())){ try { ByteArrayOutputStream stream = (ByteArrayOutputStream) evt.getNewValue(); byte[] byteArray = stream.toByteArray(); stream.flush(); Image createImage = Toolkit.getDefaultToolkit().createImage(byteArray); this.getContentPane().add(new JLabel(new ImageIcon(createImage))); } catch (IOException ex) { Logger.getLogger(ImageTest.class.getName()).log(Level.SEVERE, null, ex); } } However, I am getting a "Premature end of JPEG file sun.awt.image.ImageFormatException: JPEG datastream contains no image" error, the image is a JPG image format, is there any library or method known to make something similar?

  • Getting the right result of mouse click event

    - by Jessy
    Hello, I'm curious why I got the "right" BUT "wrong"number of result when I click the mouse. I supposed to print on the console mouseClicked once everytimes the mouse is clicked. However I got many of them printed out everytimes I clicked the mouse ...sometimes 5 e.g. mouseClicked mouseClicked mouseClicked mouseClicked mouseClicked Instead of just mouseClicked Why? public void mouseClicked(MouseEvent arg0) { System.out.println("mouseClicked"); }
