• How to check whether the tab is active or not in JTabbedPane?

  - by Supereme

  Hi, How to check whether a tab in JTabbedPane instance is active or not, in the class of the tab(nested class) itself and not in the enclosing class? I know that there is a method 'booloean isEnabledAt(int index)'; but this method can only be called in the enclosing class whereas I want to check whether the tab is currently selected or not in the tab class (nested class) itself. Can anybody please suggest me something? Thank you!

• In Javascript is there a function that returns the number of times that a given string occurs?

  - by William Calleja

  In Javascript is there a function that returns the number of times that a given string occurs? I need to return a numeric value that is equal to the number of times that a given string occurs within a particular string for instance: var myString = "This is a test text" If I had to search for 'te' in the above string it would return 2.

• Backbone.js (model instanceof Model) via Chrome Extension

  - by Leoncelot

  Hey guys, This is my first time ever posting on this site and the problem I'm about to pose is difficult to articulate due to the set of variables required to arrive at it. Let me just quickly explain the framework I'm working with. I'm building a Chrome Extension using jQuery, jQuery-ui, and Backbone The entire JS suite for the extension is written in CoffeeScript and I'm utilizing Rails and the asset pipeline to manage it all. This means that when I want to deploy my extension code I run rake assets:precompile and copy the resulting compressed JS to my extensions Directory. The nice thing about this approach is that I can actually run the extension js from inside my Rails app by including the library. This is basically the same as my extensions background.js file which injects the js as a content script. Anyway, the problem I've recently encountered was when I tried testing my extension on my buddy's site, whiskeynotes.com. What I was noticing is that my backbone models were being mangled upon adding them to their respective collections. So something like this.collection.add(new SomeModel) created some nonsense version of my model. This code eventually runs into Backbone's prepareModel code _prepareModel: function(model, options) { options || (options = {}); if (!(model instanceof Model)) { var attrs = model; options.collection = this; model = new this.model(attrs, options); if (!model._validate(model.attributes, options)) model = false; } else if (!model.collection) { model.collection = this; } return model; }, Now, in most of the sites on which I've tested the extension, the result is normal, however on my buddy's site the !(model instance Model) evaluates to true even though it is actually an instance of the correct class. The consequence is a super messed up version of the model where the model's attributes is a reference to the models collection (strange right?). Needless to say, all kinds of crazy things were happening afterward. Why this is occurring is beyond me. However changing this line (!(model instanceof Model)) to (!(model instanceof Backbone.Model)) seems to fix the problem. I thought maybe it had something to do with the Flot library (jQuery graph library) creating their own version of 'Model' but looking through the source yielded no instances of it. I'm just curious as to why this would happen. And does it make sense to add this little change to the Backbone source? Update: I just realized that the "fix" doesn't actually work. I can also add that my backbone Models are namespaced in a wrapping object so that declaration looks something like class SomeNamespace.SomeModel extends Backbone.Model

• How to verify StructureMap is disposing of objects properly

  - by Kevin Pang

  I'm currently using StructureMap to inject instances of NHibernate ISessions using the following code: ObjectFactory.Initialize(x => { x.ForRequestedType<ISession>() .CacheBy(InstanceScope.PerRequest) .TheDefault.Is.ConstructedBy(y => NHibernateSessionManager.Instance.GetSession()); }); I'm assuming that the CacheBy(InstanceScope.PerRequest) will properly dispose of the ISession it creates, but I'd like to make sure. What's the easiest way to test this?

• How to declare class attributes in swift, just like UITableViewCell reuse identifiers?

  - by martin

  I am trying to declare a reuse identifier associated to a UITableView subclass in swift. From my understanding I would like to declare an class stored property (not an instance one) so i have access via: MyCustomTableCell.ReuseIdentifer. Here is what I was trying: class MyCustomTableViewCell : UITableViewCell { class let ReuseIdentifier = "MyCustomTableViewCellReuseIdentifier" } The compiler mentions that class attributes are not supported yet. How to declare such kind of constants associated to a class type in a clean way?

• How to (simply) create new service objects in java jax-ws webservices?

  - by cibercitizen1

  Is it possible in jax-ws to have a webmethod that creates a new object (of a service class) and returns a reference to it to the client caller (for the client, it's a remote reference) so that the client and this new service object maintain a session? (Therefore each client is served by a different instance). Schematically: client server o:Session -------- -------- ---------- s = server.access() ------------------> o = new Session() return o <--- o.doSomething() ----------------------------------------------> make it <--- o.doMore() --------------------------------------------------> make it <---

• How to write backwards compatible HTML5 ?

  - by Olivier Lalonde

  I'd like to start using HTML5's basic features, but at the same time, keep my code backwards compatible with older browsers (graceful degradation). For instance, I'd like to use the cool CSS3 properties for making rounded corners. Is there any available tutorial for writing gracefully degradable HTML5 ? Additionally, what browsers should I support so that my app. is functional for at least 95% of visitors? What are the ways to test those browsers painlessly ?

• Different ways of accessing configuration parameters from a JAX-WS service

  - by ecerulm

  As far as I know I can access the web.xml <context-param>s by making my class implement ServletContextListener and use the ServletContext.getInitParam(String) to read them, but it´s cumbersome as only one instance of the class will receive the contextInitialized(ServletContextEvent sce) call, so I need to make the ServletContext an static member of the class. What other ways exist of setting conf params at deployment time and what are the recommended ones?
