And Do I have to make some planing movements thoose enemies in my code ? I want that they vill appear not on same pozition.Like First 5 enemies will come top of screen then the other 5 or 10 enemies will come from left side.. so on.What is best solution for this?

  • Wrong background colors in Swing ListCellRenderer

    - by Johannes Rössel
    I'm currently trying to write a custom ListCellRenderer for a JList. Unfortunately, nearly all examples simply use DefaultListCellRenderer as a JLabel and be done with it; I needed a JPanel, however (since I need to display a little more info than just an icon and one line of text). Now I have a problem with the background colors, specifically with the Nimbus PLAF. Seemingly the background color I get from list.getBackground() is white, but paints as a shade of gray (or blueish gray). Outputting the color I get yields the following: Background color: DerivedColor(color=255,255,255 parent=nimbusLightBackground offsets=0.0,0.0,0.0,0 pColor=255,255,255 However, as can be seen, this isn't what gets painted. It obviously works fine for the selected item. Currently I even have every component I put into the JPanel the cell renderer returns set to opaque and with the correct foreground and background colors—to no avail. Any ideas what I'm doing wrong here? ETA: Example code which hopefully runs. public class ParameterListCellRenderer implements ListCellRenderer { @Override public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { // some values we need Border border = null; Color foreground, background; if (isSelected) { background = list.getSelectionBackground(); foreground = list.getSelectionForeground(); } else { background = list.getBackground(); foreground = list.getForeground(); } if (cellHasFocus) { if (isSelected) { border = UIManager.getBorder("List.focusSelectedCellHighlightBorder"); } if (border == null) { border = UIManager.getBorder("List.focusCellHighlightBorder"); } } else { border = UIManager.getBorder("List.cellNoFocusBorder"); } System.out.println("Background color: " + background.toString()); JPanel outerPanel = new JPanel(new BorderLayout()); setProperties(outerPanel, foreground, background); outerPanel.setBorder(border); JLabel nameLabel = new JLabel("Factory name here"); setProperties(nameLabel, foreground, background); outerPanel.add(nameLabel, BorderLayout.PAGE_START); Box innerPanel = new Box(BoxLayout.PAGE_AXIS); setProperties(innerPanel, foreground, background); innerPanel.setAlignmentX(Box.LEFT_ALIGNMENT); innerPanel.setBorder(BorderFactory.createEmptyBorder(0, 10, 0, 0)); JLabel label = new JLabel("param: value"); label.setFont(label.getFont().deriveFont( AffineTransform.getScaleInstance(0.95, 0.95))); setProperties(label, foreground, background); innerPanel.add(label); outerPanel.add(innerPanel, BorderLayout.CENTER); return outerPanel; } private void setProperties(JComponent component, Color foreground, Color background) { component.setOpaque(true); component.setForeground(foreground); component.setBackground(background); } } The weird thing is, if I do if (isSelected) { background = new Color(list.getSelectionBackground().getRGB()); foreground = new Color(list.getSelectionForeground().getRGB()); } else { background = new Color(list.getBackground().getRGB()); foreground = new Color(list.getForeground().getRGB()); } it magically works. So maybe the DerivedColor with nimbusLightBackground I'm getting there may have trouble?

  • How can I Convert XML to an Object using Spring 3.0 mvc while making RESTful request

    - by brock
    Hi, I'm using the Spring 3.0 RC1 framework and I'm currently testing out Spring mvc. I wanted to use Spring mvc to handle restful requests. I have set up my controller to handle the URI request. I am passing in xml with the request. So on the controller I have a method like follows: public void request(RequestObject request) { doSomething(); } I am having a hard time converting the xml to the RequestObject. I haven't seen much documentation on this and I was wondering if anyone could point me in the right direction. I'm guess that you would have to annotate the RequestObject using JAXB or something in order to tell Spring to convert the xml file to RequestObject but I'm not sure. Thanks for all of your help!!

  • Using java2d user space measurements with TextLayout and LineBreakMeasurer

    - by Andrew Wheeler
    I have a java2d image defined in user space (mm) to print an identity card. The transformation to pixels is by using an AffineTransform for the required DPI (Screen or print). I want to wrap text across several lines but the the TextLayout does not respect user space co-ordinates. private void drawParagraph(Graphics2D g2d, Rectangle2D area, String text) { LineBreakMeasurer lineMeasurer; AttributedString string = new AttributedString(text); AttributedCharacterIterator paragraph = string.getIterator(); int paragraphStart = paragraph.getBeginIndex(); int paragraphEnd = paragraph.getEndIndex(); FontRenderContext frc = g2d.getFontRenderContext(); lineMeasurer = new LineBreakMeasurer(paragraph, frc); float breakWidth = (float)area.getWidth(); float drawPosY = (float)area.getY(); float drawPosX = (float)area.getX(); lineMeasurer.setPosition(paragraphStart); while (lineMeasurer.getPosition() < paragraphEnd) { TextLayout layout = lineMeasurer.nextLayout(breakWidth); drawPosY += layout.getAscent(); layout.draw(g2d, drawPosX, drawPosY); drawPosY += layout.getDescent() + layout.getLeading(); } } The above code determines font metrics using user space sizing of the Font and thus turn out rather large. The font size is calculated as best vertical fit for the number of lines in an area with the calculation as below. E.g. attr.put(TextAttribute.SIZE, (geTextArea().getHeight() / noOfLines - LINE_SPACING) ); When using g2d.drawString("Some text to display", x, y); the font size appears correct. Does anyone have a better way of doing text layout in user space co-ords?

  • Hibernate mapping - "Could not determine type"

    - by Pool
    I currently have the following objects persisting successfully: Person first name, etc. Exams title, date, etc. I'd like to now create a third table Exam results. For this table I believe it should be person ID, exam ID and result, and this is a many to many relationship. @Entity public class ExamResult { private Exam exam; private Person person; private double value; @Id @ManyToOne( cascade = {CascadeType.PERSIST, CascadeType.MERGE} ) @JoinColumn(name="EXAM_ID") public Exam getExam() { return exam; } public void setExam(Exam exam) { this.exam = exam; } @Id @ManyToOne( cascade = {CascadeType.PERSIST, CascadeType.MERGE} ) @JoinColumn(name="PERSON_ID") public Person getPerson() { return person; } public void setPerson(Person person) { this.person = person; } public double getValue() { return value; } public void setValue(double value) { this.value = value; } } The error: org.hibernate.MappingException: Could not determine type for: Person, at table: ExamResult, for columns: [org.hibernate.mapping.Column(person)] I think I may be going about this the wrong way, but I can't work out how to proceed with this relationship from the tutorial. Any ideas?

  • Why GWT? Advantages and Trade-Offs of Using This RIA Framework

    - by prometheus
    I'm new to stackoverflow and have been reading through a bunch of the "highest voted" questions for GWT. Several of these questions talk about the pitfalls or problems with GWT. In the articles: Which Javascript framework (jQuery vs Dojo vs … )? and Biggest GWT Pitfalls?, some posters seem to suggest that GWT is not lightweight enough or that there are better alternatives that may be used. Do most of you feel that there are problems with GWT that have not been fixed with GWT 2.0 -- which would make you inclined to suggest using a simpler framework for a new project? To some extent, shouldn't GWT be somewhat future-proof (since you don't have to worry about it changing drastically from release to release and since it is backed by Google)? I realize that the answer to this question depends greatly upon what you want to do or what you wish to make. I am looking at this from the perspective of starting a new web application that will eventually be used by millions of users.

  • Listview selects mutliple items when clicked

    - by xlph
    I'm trying to make a task manager, and I only have one problem. I have a listview that gets inflated. All the elements in the listview are correct. The problem is that when I select an item, the listview will select another item away. I've heard listviews repopulate the list as it scrolls down to save memory. I think this may be some sort of problem. Here is a picture of the problem. If i had more apps loaded, then it would continue to select multiple at once. Here is the code of my adapter and activity and XML associated public class TaskAdapter extends BaseAdapter{ private Context mContext; private List<TaskInfo> mListAppInfo; private PackageManager mPack; public TaskAdapter(Context c, List<TaskInfo> list, PackageManager pack) { mContext = c; mListAppInfo = list; mPack = pack; } @Override public int getCount() { return mListAppInfo.size(); } @Override public Object getItem(int position) { return mListAppInfo.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(final int position, View convertView, ViewGroup parent) { TaskInfo entry = mListAppInfo.get(position); if (convertView == null) { LayoutInflater inflater = LayoutInflater.from(mContext); //System.out.println("Setting LayoutInflater in TaskAdapter " +mContext +" " +R.layout.taskinfo +" " +R.id.tmbox); convertView = inflater.inflate(R.layout.taskinfo,null); } ImageView ivIcon = (ImageView)convertView.findViewById(R.id.tmImage); ivIcon.setImageDrawable(entry.getIcon()); TextView tvName = (TextView)convertView.findViewById(R.id.tmbox); tvName.setText(entry.getName()); convertView.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { final CheckBox checkBox = (CheckBox)v.findViewById(R.id.tmbox); if(v.isSelected()) { System.out.println("Listview not selected "); //CK.get(arg2).setChecked(false); checkBox.setChecked(false); v.setSelected(false); } else { System.out.println("Listview selected "); //CK.get(arg2).setChecked(true); checkBox.setChecked(true); v.setSelected(true); } } }); return convertView; public class TaskManager extends Activity implements Runnable { private ProgressDialog pd; private TextView ram; private String s; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.taskpage); setTitleColor(Color.YELLOW); Thread thread = new Thread(this); thread.start(); } @Override public void run() { //System.out.println("In Taskmanager Run() Thread"); final PackageManager pm = getPackageManager(); final ListView box = (ListView) findViewById(R.id.cBoxSpace); final List<TaskInfo> CK = populate(box, pm); runOnUiThread(new Runnable() { @Override public void run() { ram.setText(s); box.setAdapter(new TaskAdapter(TaskManager.this, CK, pm)); //System.out.println("In Taskmanager runnable Run()"); endChecked(CK); } }); handler.sendEmptyMessage(0); } Taskinfo.xml <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" android:gravity="center_horizontal"> <ImageView android:id="@+id/tmImage" android:layout_width="48dp" android:layout_height="48dp" android:scaleType="centerCrop" android:adjustViewBounds="false" android:focusable="false" /> <CheckBox android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/tmbox" android:lines="2"/> </LinearLayout> Taskpage.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <ListView android:id="@+id/cBoxSpace" android:layout_width="wrap_content" android:layout_height="400dp" android:orientation="vertical"/> <TextView android:id="@+id/RAM" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="18sp" /> <Button android:id="@+id/endButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="End Selected Tasks" /> </LinearLayout> Any ideas for what reason mutliple items are selected with a single click would be GREATLY appreciated. I've been messing around with different implementations and listeners and listadapters but to no avail.

  • Invert bitmap colors

    - by Alex Orlov
    I have the following problem. I have a charting program, and it's design is black, but the charts (that I get from the server as images) are light (it actually uses only 5 colors: red, green, white, black and gray). To fit with the design inversion does a good job, the only problem is that red and green are inverted also (green - pink, red - green). Is there a way to invert everything except those 2 colors, or a way to repaint those colors after inversion? And how costly are those operations (since I get the chart updates pretty often)? Thanks in advance :) UPDATE I tried replacing colors with setPixel method in a loop for(int x = 0 ;x < chart.getWidth();x++) { for(int y = 0;y < chart.getHeight();y++) { final int replacement = getColorReplacement(chart.getPixel(x, y)); if(replacement != 0) { chart.setPixel(x, y, replacement); } } } Unfortunetely, the method takes too long (~650ms), is there a faster way to do it, and will setPixels() method work faster?

  • Detecting when a handler couldn't be started when embedding Jetty

    - by scompt.com
    I'm embedding Jetty in a similar manner as described here. When the RequestLogHandler can't open the specified logfile, it throws an exception which is unfortunately caught by org.eclipse.jetty.server.Server and swallowed (but logged first, at least). This means that there's no obvious way for me to tell if the log handler was started correctly. Is there a way that I'm missing to detect when a handler couldn't start?

  • how can i unmarshall in jaxb and enjoy the schema validation without using an explicit schema file

    - by ekeren
    I am using jaxb for my application configurations I feel like I am doing something really crooked and I am looking for a way to not need an actual file or this transaction. As you can see in code I: 1.create a schema into a file from my JaxbContext (from my class annotation actually) 2.set this schema file in order to allow true validation when I unmarshal JAXBContext context = JAXBContext.newInstance(clazz); Schema mySchema = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI).newSchema(schemaFile); jaxbContext.generateSchema(new MySchemaOutputResolver()); // ultimately creates schemaFile Unmarshaller u = m_context.createUnmarshaller(); u.setSchema(mySchema); u.unmarshal(...); do any of you know how I can validate jaxb without needing to create a schema file that sits in my computer? Do I need to create a schema for validation, it looks redundant when I get it by JaxbContect.generateSchema ? How do you do this?

  • Distributed sequence number generation?

    I've generally implemented sequence number generation using database sequences in the past. e.g. Using Postgres SERIAL type http://neilconway.org/docs/sequences/ I'm curious though as how to generate sequence numbers for large distributed systems where there is no database. Does anybody have any experience or suggestions of a best practice for achieving sequence number generation in a thread safe manner for multiple clients?

  • How to avoid using this in a constructor

    - by Paralife
    I have this situation: interface MessageListener { void onMessageReceipt(Message message); } class MessageReceiver { MessageListener listener; public MessageReceiver(MessageListener listener, other arguments...) { this.listener = listener; } loop() { Message message = nextMessage(); listener.onMessageReceipt(message); } } and I want to avoid the following pattern: (Using the this in the Client constructor) class Client implements MessageListener { MessageReceiver receiver; MessageSender sender; public Client(...) { receiver = new MessageReceiver(this, other arguments...); sender = new Sender(...); } . . . @Override public void onMessageReceipt(Message message) { if(Message.isGood()) sender.send("Congrtulations"); else sender.send("Boooooooo"); } } The reason why i need the above functionality is because i want to call the sender inside the onMessageReceipt() function, for example to send a reply. But I dont want to pass the sender into a listener, so the only way I can think of is containing the sender in a class that implements the listener, hence the above resulting Client implementation. Is there a way to achive this without the use of 'this' in the constructor? It feels bizare and i dont like it, since i am passing myself to an object(MessageReceiver) before I am fully constructed. On the other hand, the MessageReceiver is not passed from outside, it is constructed inside, but does this 'purifies' the bizarre pattern? I am seeking for an alternative or an assurance of some kind that this is safe, or situations on which it might backfire on me.

  • Saving twice don't update my object in JDO

    - by Javi
    Hello I have an object persisted in the GAE datastore using JDO. The object looks like this: public class MyObject implements Serializable, StoreCallback { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) @Extension(vendorName="datanucleus", key="gae.encoded-pk", value="true") private String id; @Persistent private String firstId; ... } As usually when the object is stored for the first time a new id value is generated for the identifier. I need that if I don't provide a value for firstId it sets the same value as the id. I don't want to solve it with a special getter which checks for null value in firstId and then return the id value because I want to make queries relating on firstId. I can do it in this way by saving the object twice (Probably there's a better way to do this, but I'll do it in this way until I find a better one). But it is not working. when I debug it I can see that result.firstId is set with the id value and it seems to be persisted, but when I go into the datastore I see that firstId is null (as it was saved the first time). This save method is in my DAO and it is called in another save method in the service annotated with @Transactional. Does anyone have any idea why the second object in not persisted properly? @Override public MyObject save(MyObject obj) { PersistenceManager pm = JDOHelper.getPersistenceManagerFactory("transactions-optional"); MyObject result = pm.makePersistent(obj); if(result.getFirstId() == null){ result.setFirstId(result.getId()); result = pm.makePersistent(result); } return result; } Thanks.

  • How to generate hibernate POJO classes programmatically?

    - by Vatsala
    Hi I am aware of the Hibernate Eclipse plugin that helps us (through a series of screens and button clicks) to generate the POJO and DAO classes for the underlying tables. But I would like to mimic this in a runtime environment, i.e. I would like to be able to do the exact same steps programmatically , where I should be able to supply the .cfg.xml file, the reveng.xml file, the database URL, the destination folder, via a command line/ parameters within main(String[] args).. Apparently there is no such tool available which works in a pure Hibernate scenario. There is one which is tuned to generate code for the spring framework - but thats not of direct use to me right now. I tried downloading hibernate-tools.jar's source code for the eclipse plugin, but right now the src code download link at hibernate.org(new design) has been disabled for some reason. Has anyone handled such a thing before? Or can you give me some clues to do this? I have tried a certain JDBCReader class's object, the rationale being read all tables using JDBCReader's methods and then figure out how to use hbm2POJO generator class....

  • how to continuously send data without blocking?

    - by Donal Rafferty
    I am trying to send rtp audio data from my Android application. I currently can send 1 RTP packet with the code below and I also have another class that extends Thread that listens to and receives RTP packets. My question is how do I continuously send my updated buffer through the packet payload without blocking the receiving thread? public void run() { isRecording = true; android.os.Process.setThreadPriority (android.os.Process.THREAD_PRIORITY_URGENT_AUDIO); int buffersize = AudioRecord.getMinBufferSize(8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT); Log.d("BUFFERSIZE","Buffer size = " + buffersize); arec = new AudioRecord(MediaRecorder.AudioSource.MIC, 8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, buffersize); short[] readBuffer = new short[80]; byte[] buffer = new byte[160]; arec.startRecording(); while(arec.getRecordingState() == AudioRecord.RECORDSTATE_RECORDING){ int frames = arec.read(readBuffer, 0, 80); @SuppressWarnings("unused") int lenghtInBytes = codec.encode(readBuffer, 0, buffer, frames); RtpPacket rtpPacket = new RtpPacket(); rtpPacket.setV(2); rtpPacket.setX(0); rtpPacket.setM(0); rtpPacket.setPT(0); rtpPacket.setSSRC(123342345); rtpPacket.setPayload(buffer, 160); try { rtpSession2.sendRtpPacket(rtpPacket); } catch (UnknownHostException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (RtpException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } So when I send on one device and receive on another I get decent audio, but when I send and receive on both I get broken sound like its taking turns to send and receive audio. I have a feeling it could be to do with the while loop? it could be looping around in there and not letting anything else run?
