  • Applet panels, one fixed size, and dynamic JTextField

    - by Kristoffersen
    Hi, I need an applet which contains one panel. The panel needs to be 550x400 pixels, the JTextField needs to be under the panel dynamic size. I want it to be like this: [topPanel] [textPanel] However I am trying this, and it seems like the panel is filling all the space. The code: import java.awt.BorderLayout; import java.awt.Color; import java.awt.Dimension; import javax.swing.JApplet; import javax.swing.JPanel; import javax.swing.JTextField; public class Client extends JApplet { @Override public void init() { try { java.awt.EventQueue.invokeAndWait(new Runnable() { public void run() { initComponents(); } }); } catch (Exception ex) { ex.printStackTrace(); } } private void initComponents() { JPanel topPanel = new javax.swing.JPanel(); topPanel.setBackground(Color.red); topPanel.setSize(550, 400); topPanel.setPreferredSize(new Dimension(550, 400)); topPanel.setMinimumSize(new Dimension(550, 400)); topPanel.setMaximumSize(new Dimension(550, 400)); JTextField myTextBox = new JTextField(255); getContentPane().add(topPanel, java.awt.BorderLayout.NORTH); getContentPane().add(myTextBox, java.awt.BorderLayout.SOUTH); } // TODO overwrite start(), stop() and destroy() methods } Thanks!

  • Calling a method within Portlet when submitting form

    - by Roland
    I have a Portlet that contains a form. Now what I want to achieve is the following. 1) A Porlet containing a form is called within a page via <?php $this->widget('form'); ?> 2) The user fills in this form and clicks on submit "The submit button should be an ajax button" 3) When submit has been pressed the form should call a method within the form portlet class and the form should be replaced with a Thank you message. 4) I only want the current view in the portlet replaced with another view. My portlet class looks like this Yii::import('zii.widgets.CPortlet'); class Polls extends CPortlet{ public $usr_id=''; public function init(){ $cs = Yii::app()->clientScript; $cs->registerCoreScript('jquery'); parent::init(); } protected function renderContent(){ $this->render('form'); } public function update(){ $this->render('thankyou'); } } } Any advise, help would be highly appreciated.

  • casting Collection<SomeClass> to Collection<SomeSuperClass>

    - by skrebbel
    Hi all, I'm sure this has been answered before, but I really cannot find it. I have a java class SomeClass and an abstract class SomeSuperClass. SomeClass extends SomeSuperClass. Another abstract method has a method that returns a Collection<SomeSuperClass>. In an implementation class, I have a Collection<SomeClass> myCollection I understand that I cannot just return myCollection, because Collection<SomeClass> does not inherit from Collection<SomeSuperClass>. Nevertheless, I know that everything in myCollection is a SomeSuperClass because after all, they're SomeClass objects which extend SomeSuperClass. How can I make this work? I.e. I want public class A { private Collection<SomeClass> myCollection; public Collection<SomeSuperClass> getCollection() { return myCollection; //compile error! } } The only way I've found is casting via a non-generic type and getting unchecked warnings and whatnot. There must be a more elegant way, though? I feel that also using Collections.checkedSet() and friends are not needed, since it is statically certain that the returned collection only contains SomeClass objects (this would not be the case when downcasting instead of upcasting, but that's not what I'm doing). What am I missing? Thanks!

  • Adding time to a timer/counter

    - by BoneStarr
    I've looked all over the web and everyone can teach you how to make a timer for your game or a countdown, but I can't seem to find out how to add time to an already counting timer. So here is my counter class: package { import flash.display.MovieClip; import flash.display.Stage; import flash.text.TextField; import flash.events.Event; import flash.utils.Timer; import flash.events.TimerEvent; public class Score extends MovieClip { public var second:Number = 0; public var timer:Timer = new Timer(100); private var stageRef:Stage; public function Score(stageRef:Stage) { x = 560.95; y = 31.35; this.stageRef = stageRef; timer.addEventListener(TimerEvent.TIMER, scoreTimer); timer.start(); } public function scoreTimer(evt:TimerEvent):void { second += 1; scoreDisplay.text = String("Score: " +second); } That works without any issues or problems and just keeps counting upwards at a speed of 100ms, what I want to know is how to add say 30 seconds if something happens in my game, say you kill an enemy for example. Please help!

  • How can I control the width of JTextFields in Java Swing?

    - by Jonas
    I am trying to have several JTextFields on a single row, but I don't want them to have the same width. How can I control the width and make some of them wider than others? I want that they together take up 100% of the total width, so it would be good if I could use some kind of weigthing. I have tried with .setColumns() but it doesn't make sense. Here is my code: class Row extends JComponent { public Row() { this.setLayout(new BoxLayout(this, BoxLayout.X_AXIS)); JTextField fld1 = new JTextField("First field"); JTextField fld2 = new JTextField("Second field, should be longer"); JTextField fld3 = new JTextField("Short field"); JTextField fld4 = new JTextField("Another field"); fld1.setBorder(null); fld2.setBorder(null); fld3.setBorder(null); fld4.setBorder(null); fld1.setFocusable(false); fld2.setFocusable(false); fld3.setFocusable(false); fld4.setFocusable(false); fld1.setColumns(5); // makes no sense this.add(fld1); this.add(fld2); this.add(fld3); this.add(fld4); } } this.setLayout(new GridLayout(20,0)); this.add(new Row()); this.add(new Row()); this.add(new Row());

  • CustomProfile is not saving?

    - by Xaisoft
    I created a class that extends ProfileBase: public class CustomerProfile : ProfileBase { public int CustomerID { get; set; } public string CustomerName { get; set; } public static CustomerProfile GetProfile() { return Create(Membership.GetUser().UserName) as CustomerProfile; } public static CustomerProfile GetProfile(string userName) { return Create(userName) as CustomerProfile; } } If I do: CustomerProfile p = CustomerProfile.GetProfile(); p.CustomerID = 1; p.Save(); The next time I try to access the value for the current user, it is not 1, it is 0, so it appears it is not saving it in the database. In my web.config file I have the following snippet: <profile inherits="PortalBLL.CustomerProfile"> <providers> <add name="CustomerProfile" type="System.Web.Profile.SqlProfileProvider" applicationName="/" connectionStringName="LocalSqlServer"/> </providers> </profile> I tried the following and it worked, I am curious why it doesn't save it using the automatic properties. [SettingsAllowAnonymous(false)] public int CustomerID { get { return (int)base.GetPropertyValue("CustomerID");} set { base.SetPropertyValue("CustomerID",value);} }

  • Multiple threads modifying a collection in Java??

    - by posdef
    Hi, The project I am working on requires a whole bunch of queries towards a database. In principle there are two types of queries I am using: read from excel file, check for a couple of parameters and do a query for hits in the database. These hits are then registered as a series of custom classes. Any hit may (and most likely will) occur more than once so this part of the code checks and updates the occurrence in a custom list implementation that extends ArrayList. for each hit found, do a detail query and parse the output, so that the classes created in (I) get detailed info. I figured I would use multiple threads to optimize time-wise. However I can't really come up with a good way to solve the problem that occurs with the collection these items are stored in. To elaborate a little bit; throughout the execution objects are supposed to be modified by both (I) and (II). I deliberately didn't c/p any code, as it would be big chunks of code to make any sense.. I hope it make some sense with the description above. Thanks,

  • django - variable declared in base project does not appear in app

    - by unsorted
    I have a variable called STATIC_URL, declared in settings.py in my base project: STATIC_URL = '/site_media/static/' This is used, for example, in my site_base.html, which links to CSS files as follows: <link rel="stylesheet" href="{{ STATIC_URL }}css/site_tabs.css" /> I have a bunch of templates related to different apps which extend site_base.html, and when I look at them in my browser the CSS is linked correctly as <link rel="stylesheet" href="/site_media/static/css/site_tabs.css" /> (These came with a default pinax distribution.) I created a new app called 'courses' which lives in the ...../apps/courses folder. I have a view for one of the pages in courses called courseinstance.html which extends site_base.html just like the other ones. However, when this one renders in my browser it comes out as <link rel="stylesheet" href="css/site_tabs.css" /> as if STATIC_URL were equal to "" for this app. Do I have to make some sort of declaration to get my app to take on the same variable values as the project? I don't have a settings.py file for the app. by the way, the app is listed in my list of INSTALLED_APPS and it gets served up fine, just without the link to the CSS file (so the page looks funny). Thanks in advance for your help.

  • Java swing hold buttons

    - by Simon Charette
    Hi, I'm trying to create a subclass of JButton or AbstractButton that would call specified .actionPerformed as long as the mouse is held down on the button. So far I was thinking of extending JButton, adding a mouse listener on creation (inside constructor) and calling actionPerformed while the mouse is down. So far i came up with that but I was wondwering if I was on the right track and if so, how to correctly implement the "held down" logic. package components; import java.awt.event.ActionEvent; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.Action; import javax.swing.Icon; import javax.swing.JButton; public class HoldButton extends JButton { private class HeldDownMouseListener implements MouseListener { private boolean mouseIsHeldDown; private HoldButton button; private long millis; public HeldDownMouseListener(HoldButton button, long millis) { this.button = button; this.millis = millis; } @Override public void mouseClicked(MouseEvent arg0) { } @Override public void mouseEntered(MouseEvent arg0) { } @Override public void mouseExited(MouseEvent arg0) { } @Override public void mousePressed(MouseEvent arg0) { mouseIsHeldDown = true; // This should be run in a sub thread? // while (mouseIsHeldDown) { // button.fireActionPerformed(new ActionEvent(button, ActionEvent.ACTION_PERFORMED, "heldDown")); // try { // Thread.sleep(millis); // } catch (InterruptedException e) { // e.printStackTrace(); // continue; // } // } } @Override public void mouseReleased(MouseEvent arg0) { mouseIsHeldDown = false; } } public HoldButton() { addHeldDownMouseListener(); } public HoldButton(Icon icon) { super(icon); addHeldDownMouseListener(); } public HoldButton(String text) { super(text); addHeldDownMouseListener(); } public HoldButton(Action a) { super(a); addHeldDownMouseListener(); } private void addHeldDownMouseListener() { addMouseListener(new HeldDownMouseListener(this, 300)); } } Thanks a lot for your time.

  • System.out.println() does not operate in Akka actor

    - by faisal abdulai
    I am kind of baffled by this encointer. I am working an akka project that was created as a maven projecct and imported into eclipse using the mvn eclipse:eclipse command. the akka actor has the system println method just to make it easy to do read the functions and methods invoked. However any time I run the akka system, the println command does not print any thing to the eclipse console but I do not get any error messages. does any one have any idea about this. below is a code snippet. public class MasterActor extends UntypedActor { /** * */ ActorSystem system = ActorSystem.create("container"); ActorRef worker1; //public MasterActor(){} @Override public void onReceive(Object message) throws Exception { System.out.println(" Master Actor 5"); if(message instanceof GesturePoints) { //GesturePoints gp = (GesturePoints) message; System.out.println(" Master Actor 1"); try { worker1.tell(message, getSelf()); System.out.println(" Master Actor 2"); } catch (Exception e) { getSender().tell(new akka.actor.Status.Failure(e), getSelf()); throw e; } } else{ unhandled(message);} } public void preStart() { worker1 = getContext().actorFor("akka://[email protected]:2553/user/workerActor"); } } don't know whether it is a bug in eclipse. thank you.

  • Best Practice With JFrame Constructors?

    - by David Barry
    In both my Java classes, and the books we used in them laying out a GUI with code heavily involved the constructor of the JFrame. The standard technique in the books seems to be to initialize all components and add them to the JFrame in the constructor, and add anonymous event handlers to handle events where needed, and this is what has been advocated in my class. This seems to be pretty easy to understand, and easy to work with when creating a very simple GUI, but seems to quickly get ugly and cumbersome when making anything other than a very simple gui. Here is a small code sample of what I'm describing: public class FooFrame extends JFrame { JLabel inputLabel; JTextField inputField; JButton fooBtn; JPanel fooPanel; public FooFrame() { super("Foo"); fooPanel = new JPanel(); fooPanel.setLayout(new FlowLayout()); inputLabel = new JLabel("Input stuff"); fooPanel.add(inputLabel); inputField = new JTextField(20); fooPanel.add(inputField); fooBtn = new JButton("Do Foo"); fooBtn.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { //handle event } }); fooPanel.add(fooBtn); add(fooPanel, BorderLayout.CENTER); } } Is this type of use of the constructor the best way to code a Swing application in java? If so, what techniques can I use to make sure this type of constructor is organized and maintainable? If not, what is the recommended way to approach putting together a JFrame in java?

  • How to use my trackpad for horizontal mousewheel scrolling in a Java AWT ScrollPane

    - by blissapp
    Like many modern mice and trackpads, my laptop supports vertical and horizontal scrolling. It's an addictive feature once you get used to it. I simply want my Java apps to support horizontal scrolling via the trackpad/mousewheel, but everywhere I search it seems that this is not possible in Java. I really want someone to tell me that I'm somehow doing it wrong, this feature is already requested behaviour: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6440198 The inability to do this simple thing is actually a deal breaker for the app I'm working on. In fact, for any app I can envision! I've invested a bit of time in the Java backend, so I'd really like to find a solution for this seemingly simple thing. Question is what could I do to implement this behaviour? Are raw OS level events even exposed to java, would I then need to write this from scratch? import java.awt.*; public class ScrollExample extends Canvas { public void paint(Graphics g) { g.setColor(Color.green); g.fillOval(0,0,400, 400); } public static void main(String[] args) { ScrollExample b = new ScrollExample(); Frame f = new Frame ("Scroll Example"); ScrollPane scroller = new ScrollPane (ScrollPane.SCROLLBARS_ALWAYS); scroller.add(b,"Center"); f.setPreferredSize(new Dimension(500,500)); f.add ("Center",scroller); f.pack(); f.show(); } }

  • Google Maps: How does Trulia create their custom InfoWIndows?

    - by NickT
    I really like how Trulia.com has created their custom Google Map InfoWindows. What I like in particular about Trulia's implementation of the InfoWindow is: Extends beyond the map border: Google Maps InfoWindows are contained within the map border whereas Trulia's seems to be able to float on-top of the map Always displays InfoWindow near map Center: Google Maps InfoWindows always display the InfoWindow above the marker whereas Trulia InfoWindows always display the InfoWindow as close the center of the map as possible. For example, if the map marker icon is on the top of the map near the border, the Trulia InfoWindow is displayed below the map marker icon InfoWindow is displayed on mouse hover (not 'click'): With the default Google Maps InfoWindow, you have to 'click' the map marker icon to display the InfoWindow whereas Trulia InfoWindows are display simply by hovering over the map marker icon. I found the PdMarker, which is a 3rd party extension for Google Map InfoWindows that accomplishes most of the above bullets but not all. 1) It does not extend beyond the map border, 2) it does not work with Google Maps API version 3 (only version 2). Anyone know how Trulia is accomplishing their InfoWindow-like implementation on Google Maps API v3?

  • Pronunciation of programming structures (particularly in c#)

    - by Andrzej Nosal
    As a non-English speaking person I often have problems pronouncing certain programming structures and abbreviations. I've been watching some video tutorials and listening to podcasts as well, though I couldn't catch them all. My question is what is the common or correct pronunciation of the following code snippets? Generics, like IEnumerable<int> or in a method void Swap<T>(T lhs, T rhs) Collections indexing and indexer access e.g. garage[i], rectangular arrays myArray[2,1] or jagged[1][2][3] Lambda operator =>, e.g. in a where extension method .Where(animal => animal.Color == Color.Brown) or in an anonymous method () => { return false;} Inheritance class Derived : Base (extends?) class SomeClass : IDisposable (implements?) Arithemtic operators += -= *= /= %= ! Are += and -= pronounced the same for events? Collections initializers new int[] { 4, 5, 8, 9, 12, 13, 16, 17 }; Casting MyEnum foo = (MyEnum)(int)yourFloat; (as?) Nullables DateTime? dt = new DateTime?(); I tagged the question with C# as some of them are specific to C# only.

I would like to show the amount of rows to the user, and think that the perfect place for that would be next to the Fragment's title in the ViewPagerIndicator. I provided a sample image for better comprehension: Sadly I am pretty clueless how to achieve this. I tried the following: public class PagerAdapter extends FragmentPagerAdapter { private int numOne = 0; private int numTwo = 0; // ... @Override public CharSequence getPageTitle(int position) { switch (position) { case 0: return "List 1 (" + numOne + ")"; case 1: return "List 2 (" + numTwo + ")"; default: return ""; } public void setNumOne(int num) { this.numOne = num; } public void setNumTwo(int num) { this.numTwo = num; } } When I now call the setNumXXX() method, nothing happens, until I move between fragments, what seems to trigger the getPageTitle() to fire. My question is: How can I force an update of the title(s), everytime when the num value changes?
