OPERA DRAGONFLY: NEW WEB TOOLING

By admin

Opera Dragonfly

Opera has posted what looks like a great new Web debugging tool Opera Dragonfly which is released in alpha.

Debug JavaScript, inspect CSS and the DOM, and view any errors – Opera Dragonfly makes developing using Opera easier than ever, both on your computer and mobile phone.

Shawn Lauriat has a nice write-up that tells the story:

It offers most of the familiar tools for DOM inspection (along with a nice DOM editing capability), error logging (with the same granularity as before wrapped in a more polished UI), a JavaScript debugger that rivals WebKit’s Drosera, a JavaScript thread logger, and a lot more that I haven’t explored yet.

Time will tell whether Dragonfly can get enough developers to use Opera and keep them there, and how much the developers behind the new developer tools listen to the community in the coming iterations, but so far this looks extremely promising.

Features

  • Reach breaking point step by step: Opera Dragonfly’s fully featured JavaScript debugger makes building sophisticated Ajax applications easier than ever. Step through your code line by line, setting break points along the way. This allows you to make sure your application and scripts are acting as you designed them.
  • Redefine your style: Its not just the DOM you can inspect. Check out what CSS rules apply to which element, and what rules are inherited or set by browser defaults. Overridden rules are highlighted so you can see what styles are or aren’t applied. Support for editing CSS rules will be added in an upcoming version.
  • Spot your errors: An improved error console allows you to see, filter and log any errors in your scripts, pointing to the exact position the error occurred. Use this in combination with the other tools to hunt down and fix your site’s bugs.
  • Debug the DOM: View source isn’t much use if you use DOM Scripting to alter the DOM. Opera Dragonfly allows you to inspect the updated DOM and all it’s properties. Support for editing the DOM will be added in an upcoming version.

The features that are not there yet, but are upcoming, include support for editing of CSS, JavaScript and the DOM, a single window mode, improved JavaScript thread handling, XHR and HTTP monitoring, improved keyboard navigation, and translation into a number of languages.

AJAX PIONEER WEEK: BRUCE JOHNSON OF GWT

By admin

Today we have Bruce Johnson of the GWT team talking to us about GWT 1.5. He discusses the new features, such as the long awaited Java 5 language support, performance improvements, and much more.

It is very nice to take an application, run it through the new GWT 1.5 compiler, and get an instantly faster running application “for free”.

PORTING DOJO METHODS TO FLASH

By admin

Mike Wilcox has started a nice series of posts on porting Dojo methods to Flash as a homage for Open Screen (aside: I applaud Adobe's intentions, but need to see a non-assert of their IP before I can do anything with it.)

In part one of the series Mike ports dojo.hitch to ActionScript:

PLAIN TEXT
JAVASCRIPT:
  1.  
  2. _global.lang = {
  3.         hitch: function(scope, method){
  4.                 if(!method){
  5.                         method = scope;
  6.                         scope = _global;
  7.                 }
  8.                 var args;
  9.                 if(arguments.length>2){
  10.                         args = arguments;
  11.                         args.shift();
  12.                         args.shift();
  13.                 }
  14.                 if(typeof(method) == "string"){
  15.                         return  function(){ scope[method].apply(scope, args) };
  16.                 }
  17.                 return function(){ method.apply(scope, args) };
  18.         }
  19. }
  20.  

In part two he adds support for dojo.connect(), resulting in:

PLAIN TEXT
JAVASCRIPT:
  1.  
  2. _global.lang = {
  3.         __conListeners:{},
  4.         __id:0,
  5.         connect: function(source, event, target, callback){
  6.                 var hitched = this._hitch(target, callback);
  7.  
  8.                 var listener = new Object();
  9.                 listener[event] = function(args){
  10.                         hitched();
  11.                 }
  12.  
  13.                 if(!source.broadcasters) {
  14.                         source.broadcasters = {};
  15.                         AsBroadcaster.initialize(source)
  16.                 }
  17.  
  18.                 source.addListener(listener);
  19.  
  20.                 if(!source.broadcasters[event]){
  21.                         source[event] = function(){
  22.                                 source.broadcastMessage(event, arguments);
  23.                         }
  24.                         source.broadcasters[event] = true;
  25.                 }
  26.  
  27.                 var id = "connect_"+this.__id++;
  28.                 this.__conListeners[id] = {listener:listener, source:source};
  29.                 return id;
  30.         }
  31.  
  32.         disconnect: function(id){
  33.                 var con = this.__conListeners[id];
  34.                 if(con){
  35.                         con.source.removeListener(con.listener);
  36.                         con = null;
  37.                 }
  38.         }
  39. }
  40.

DETAILS OF BUTTON PADDING IN VARIOUS BROWSERS

By admin

After building a slide deck with Ben, you learn the art of a perfectionist. He would love Chris Hester's posting on button padding that shows you how your buttons look on various browsers and operating systems. Even been frustrated when you try to style things on the Mac?

Here are a few of his findings:

  • IE 6 and 7 apply extra padding to buttons with < 2px, but IE 8 doesn't
  • IE 8 and Opera add borders to all standard buttons if you zoom large enough
  • Padding on the standard buttons has no effect on Mac Firefox, and Safari on both Mac and Windows

If you are ease streaming cyberspace Explorer 6, then XPSP3 module be offered to you via Windows Update as a broad antecedency update. You crapper safely establish XPSP3 and module hit an updated edition of IE6 with every your individualized preferences, much as bag pages and favorites, ease intact.
