  • Need Java Swing equivalent of "scrollIntoView" from Browser DOM

    - by bgould
    I have a JPanel with several levels of child components, also with a JScrollPane. I'm placing a focus listener on some of the child components to add some behavior to those components, but I would also like to have that component scroll into the JPanel's viewport when focus is gained. My question is, does anyone have a general purpose function to do this, similar to the browser DOM function "scrollIntoView"? I've tried muddling through this with various inputs to JComponent.scrollRectToVisible but I guess I haven't figured out the magic word. Thanks in advance.

  • How to create and Expression tree to do the same as "StartsWith"

    - by Jonathan
    Hi to all. Currently, I have this method to compare two numbers Private Function ETForGreaterThan(ByVal query As IQueryable(Of T), ByVal propertyValue As Object, ByVal propertyInfo As PropertyInfo) As IQueryable(Of T) Dim e As ParameterExpression = Expression.Parameter(GetType(T), "e") Dim m As MemberExpression = Expression.MakeMemberAccess(e, propertyInfo) Dim c As ConstantExpression = Expression.Constant(propertyValue, propertyValue.GetType()) Dim b As BinaryExpression = Expression.GreaterThan(m, c) Dim lambda As Expression(Of Func(Of T, Boolean)) = Expression.Lambda(Of Func(Of T, Boolean))(b, e) Return query.Where(lambda) End Function It works fine and is consumed in this way query = ETForGreaterThan(query, Value, propertyInfo) As you can see, I give it an IQueryable collection and it add a where clause to it, base on a property and a value. Y can construct Lessthan, LessOrEqualThan etc equivalents as Expression has this operators predefined. ¿How can I transform this code to do the same with strings? Expression don't give me a predefined operator like "contains" or "startwith" and I'm really noob with Expression trees. Thanks, and please Post your answer in C#/VB. Choose the one that make you feel more confortable.

  • Class works without declaring variables?

    - by Maxim Droy
    I'm learned php as functional and procedure language. Right now try to start learn objective-oriented and got an important question. I have code: class car { function set_car($model) { $this->model = $model; } function check_model() { if($this->model == "Mercedes") echo "Good car"; } } $mycar = new car; $mycar->set_car("Mercedes"); echo $mycar->check_model(); Why it does work without declaration of $model? var $model; in the begin? Because in php works "auto-declaration" for any variables? I'm stuck

  • Const Functions and Interfaces in C++

    - by 58gh1z
    I'll use the following (trivial) interface as an example: struct IObject { virtual ~IObject() {} virtual std::string GetName() const = 0; virtual void ChangeState() = 0; }; Logic dictates that GetName should be a const member function while ChangeState shouldn't. All code that I've seen so far doesn't follow this logic, though. That is, GetName in the example above wouldn't be marked as a const member function. Is this laziness/carelessness or is there a legitimate reason for this? What are the major cons of me forcing my clients to implement const member functions when they are logically called for?

  • Looping class, for template engine kind of thing

    - by tarnfeld
    Hey, I am updating my class Nesty so it's infinite but I'm having a little trouble.... Here is the class: <?php Class Nesty { // Class Variables private $text; private $data = array(); private $loops = 0; private $maxLoops = 0; public function __construct($text,$data = array(),$maxLoops = 5) { // Set the class vars $this->text = $text; $this->data = $data; $this->maxLoops = $maxLoops; } // Loop funtion private function loopThrough($data) { if( ($this->loops +1) > $this->maxLoops ) { die("ERROR: Too many loops!"); } else { $keys = array_keys($data); for($x = 0; $x < count($keys); $x++) { if(is_array($data[$keys[$x]])) { $this->loopThrough($data[$keys[$x]]); } else { return $data[$keys[$x]]; } } } } // Templater method public function template() { echo $this->loopThrough($this->data); } } ?> Here is the code you would use to create an instance of the class: <?php // The nested array $data = array( "person" => array( "name" => "Tom Arnfeld", "age" => 15 ), "product" => array ( "name" => "Cakes", "price" => array ( "single" => 59, "double" => 99 ) ), "other" => "string" ); // Retreive the template text $file = "TestData.tpl"; $fp = fopen($file,"r"); $text = fread($fp,filesize($file)); // Create the Nesty object require_once('Nesty.php'); $nesty = new Nesty($text,$data); // Save the newly templated text to a variable $message $message = $nesty->template(); // Print out $message on the page echo("<pre>".$message."</pre>"); ?> Any ideas?

But to use a second dimension, I need to override getProperty method, like following code. package { import flash.utils.flash_proxy; import mx.collections.ListCollectionView; public class SubClass extends ListCollectionView /* extends Proxy */ { override flash_proxy function getProperty(name : *) : * { ... } override flash_proxy function setProperty(name : *, value : *) : void { ... } } } This code doesn't work. Flash Builder 4 said to me: 1004 Namespace was not found or is not a compile-time constant. If anyone has a solution or a clue...

  • how to get reply from jQuery.get request

    I have a page that uses the following to submit a AJAX request: function oc() { jQuery.get( "http://somewhere.com:5001/ajax/options/", jQuery('#selectform').serialize(), function(data,statusm,xml){ // I got nothing!!! return; } ); } If I make the request manual from the address bar, things work. And when I make the request from the JS I can see via logging that the server side is working correctly, but in the call back, I can't seem to get the contents of the reply. What am I going wrong?

  • jQuery: add border on hovered element but NOT parents

    - by John Isaacks
    I have this code: var originalBorder = container.css("border"); container.hover(function(event) { event.stopPropagation(); $(this).css("border", "1px solid "+options.color); },function(){ $(this).css("border", originalBorder); }); Which I am using to add a border to the currently hovered element. However for example if a span is inside a div they are both getting borders. I only want to target the span. I thought that adding event.stopPropagation() would do the trick (this is what I would do in Flex, which is what I am more used to) but I guess this is a live event which I dont even understand what that means. So basically how can target the youngest element without triggering the parents? Thanks!!

  • YUI Image Loader Images Above Fold Not Loading Until Scroll event.

    - by Mike
    I have a function that is called on the window.onload event to create a group of images and render via the scroll event. function LoadImages(){ var foldGroup = new YAHOO.util.ImageLoader.group(window, 'scroll'); for(var i=0; i<someCounter; i++){ var locationId = locationsArr[i]; foldGroup.registerSrcImage('Location_' + locationId, GetImageDomain()+'/templates/Includes/imagehandler.ashx?locationId=' + locationid); } foldGroup.foldConditional = true; foldGroup.addTrigger(window, 'resize'); } The problem I'm having is that when the page loads, the images "above the fold" are not rendered until I scroll. Is there any tips on troubleshooting this? I'm totally not a js/frontend guy :) Thanks in advance!

  • Dynamic change of class of <TR> with Jquery

    - by Coronier
    Hi all, This is my first post, and first please forgive me for my poor english. I have a problem I really can't fix: I have a <table> of questions, the first question is visible (class:visible), the others are hidden (class:hidden) $(document).ready(function(){ $('.hidden').hide(); When people click on the first question, I want the second question to appear (and the first question to turn to grey, using a 'done' class). $('.visible:not(.done)').click(function(){ $(this).addClass('done'); $('.hidden:first').toggle(500).removeClass('hidden').addClass('visible'); }) The first question is now done (class:done) and the 2nd question should be the only one to react to a click(), and so on... But it doesn't work: the other <tr> appear only when I click on the 1st <tr>. Can someone give me a hand on this problem ? Thank you.

  • Scala : reference is ambiguous (imported twice)

    - by tk
    I want to use a method as a parameter of another method of the same class. I have a class and objects which are companions: class mM(var elem:Matrix){ //apply a function on a dimension rows (1) or cols (2) def app(func:Iterable[Double]=>Double)(dim : Int) : Matrix = { ... } //utility function def logsumexp(): Double = {...} } object mM{ def apply(elem:Matrix):mM={new mM(elem)} def logsumexp(elem:Iterable[Double]): Double ={ this.apply(elem.asInstanceOf[Matrix]).logsumexp() } } Normally I use logsumexp like this mM(matrix).logsumexp but if want to apply it to the rows I can't use mM(matrix).app(mM.logsumexp)(1), I get the error: error: reference to mM is ambiguous; it is imported twice in the same scope by import mM and import mM What is the most elegant solution ? Should I change logsumexp() to another class ? Thanks,=)

    Hi all, long-time lurker here, finally emerging from the woodwork. Essentially, what I'm trying to do is have my logger write data like this to the logfile: Connecting to database . . . Done. I'd like the 'Connecting to database . . . ' to be written when the function is called, and the 'Done' written after the function has successfully executed. I'm using Python 2.6 and the logging module. Also, I'd really like to avoid using decorators for this. Any help would be most appreciated!

  • Haskell: Problems with overloading: Interpreter can´t tell which + to use

    - by Ben
    Hi, I want to make functions Double - Double an instance of the Num typeclass. I want to define the sum of two functions as sum of their images. So I wrote instance Num Function where f + g = (\ x - (f x) + (g x)) Here the compiler complains he can´t tell whether I´m using Prelude.+ or Module.+ in the lambda expression. So I imported Prelude qualified as P and wrote instance Num Function where f + g = (\ x - (f x) P.+ (g x)) This compiles just fine, but when I try to add two functions in GHCi the interpreter complains again he can´t tell whether I´m using Prelude.+ or Module.+. Is there any way I can solve this problem?

  • different for lusses java

    - by Ayrton
    Hi I'm having some difficulties with the following problem: I'm making a little game where you're at a specific spot and each spot has each some possible directions. The available directions are N(ord),E(ast),S,W . I use the function getPosDirections to get the possible directions of that spot. The function returns the directions into an ArrayList e.g. for spot J3: [E,W] Now the game goes like this: 2 dices will be rolled so you get a number between 2 and 12, this number represents the number of steps you can make. What I want is an ArrayList of all the possible routes e.g.: I throw 3 and I'm currently at spot J3: [[E,N,E],[E,N,S],[E,S,E],[E,S,S],[W,N,E],[W,N,S],[W,S,E],[W,S,S]] How would obtain the last mentioned Array(list) Thanks in advance
