• Why do toast notifications die if delayed?

  - by ubershmekel

  I'm not sure this is the exact cause of my problem but I'll explain the 2 symptoms I noticed: If I put a break point on a Toast.makeText(..).show(), step over, then wait a few seconds before running, the toast will never appear. I have a location callback that tries to show a toast, but it never appears. Maybe I'm doing something else wrong, this is the line in question in my open source distress signal app. Any help or pointers would be appreciated, --uber

• How to move an anonymous function out

  - by cf_PhillipSenn

  I have a $.ajax call with an error callback: error: function(result){ $('#msg').text(result.statusText).addClass('err'); } I'd like to change it to a more generic: error: myError(result) And then all by itself: function myError(theError){ $('#msg').text(theError.statusText).addClass('err'); } But firebug is telling me "result" is not defined.

• Client-side Twitter API method using XMLHttpRequest?

  - by user359239

  Does (or did) Twitter ever have a method in their API that allowed client-side HTTP requests without producing any cross-domain issues? I have a site that used the following url: http://search.twitter.com/search.json?q=from%3adaleyjem&rpp=3&page=1&callback=? It once worked, but now it doesn't. Is there something else I should be using, or do I have to make a request to my own server-side code?

• Nonblocking io webserver/framework for java

  - by SeekingNonblockingIo

  Does anyone know of any node.js style webserver framework for java? I realized that having nonblocking callback behavior while handling a web request will require deep support at the webserver level. I am interested in node.js, but when I have a web server that ends up persisting data, I would like to take advantage of the static type system that Java offers. However, I want the scalability of non-blocking io.

• getJSON and variable scope in javascript

  - by nillls

  Hi! In order to make function calls to our back-end php code we've implemented something called an ActionProxy like this: function ActionProxy(action, input, callback){ $.post("ActionProxy.php?method="+action, { data: input}, function(data, textStatus, XMLHttpRequest){ //return data.ResponseWhatever } }); The problem we're having is that using data outside the ActionProxy is impossible due to variable scope limitations (we assume), setting var res = data.ResponseWhatever or return data.ResponseWhatever is pretty futile. How would one handle these responses most appropriately so that functions calling the actionproxy can access the response values?

• Is it possible to make ListView display a text obtained through its ListViewItem.Tag?

  - by Dimitri C.

  I'd like to fill System.Windows.Forms.ListView with the items I've stored in a separate System.Collections.Generics.List<. I would like to avoid to store the data twice, once in the List< and once as a string in ListViewItem. Is there a way to make ListViewItem use some callback function to obtain the text to put in its columns from the Tag property, instead of using its Text property?

• How to pass non-fatal warnings from a library

  - by wRAR

  A library function parses a file and returns an object. If a parser encounters unknown data, missing values etc., it shouldn't throw an exception and stop parsing (because this is not fatal), but there should be a way to pass information about these things to a caller (so that warnings can be displayed in the UI, for example). How can these warning be returned? I'm thinking of passing a callback function/object into the library, are there any other possible solutions?

• BlockingQueue decorator that logs removed objects

  - by scompt.com

  I have a BlockingQueue that's being used in a producer-consumer situation. I would like to decorate this queue so that every object that's taken from it is logged. I know what the straightforward implementation would look like: simply implement BlockingQueue and accept a BlockingQueue in the constructor to which all of the methods would delegate. Is there another way that I'm missing? A library perhaps? Something with a callback interface?

• JQuery UI: is it possible to know where an object has been dropped?

  - by Jack Duluoz

  Hi, what I want to do is to know where (not in terms of position (x, y), but a reference to the DOM element) an object was dropped. I have a grid made up with divs where you can drop various items and I need to know which div on the grid was the item dropped on (getting its id would be fine). The callback function function(event, ui) { //code here } has just that ui object who doesn't apparently contain any information about this, but only about the draggable item or its helper.

• PHP debugging or performance Hook

  - by Joshua

  In an interpreted language like PHP it is possible in theory to set up some sort of callback function that would be run indiscriminately after every line of code. I am wondering if such a thing exists in PHP or if such a thing could be accomplished in any way? Such a feature could be useful for diagnostics or performance tests. Does anyone know of such a mechanism in PHP?

• FLEX: How to know when a dialog created throw PopUpManager Closes

  - by WeeJavaDude

  Is there a easy way to figure out consistently when a Dialog closes that has been created through PopUpManager. I would have suspected some type of message or callback mechanism, but there does not seem to be. In one case I use the WindowTitle component and event that only fires the CLOSE if someone presses the close and give no message when the dialog actually closes.

• JSON-P and a GET resource?

  - by user246114

  Hi, If a website operating on a domain other than my own supports get requests, like: http://api.someothersite.com/v1/farms There's no way for me to access it using JSON-P right, they would have to have support for it as a query parameter? Something like: http://api.someothersite.com/v1/farms?callback=fantastic I mean, there's no way for me to use it without them explicitly supporting it, right? Thanks
