    <p>I'm new to Action-script OOP and i need to know how to chain methods like this example i have </p> <p><code>I.$(button).bind('click',clickButton).bind('rollover',overButton).bind('rollout',outButton)</code></p> <p>First i need to remove the <code>I.</code> to use dollar sign only like jQuery :) to select MovieClip and apply any action on it second issue that i have because this way i'm using static Methods Action-script restrict's me to use only static property saving the last one who called the action here is the class code to know what i mean:</p> <pre><code>package com.MAIN { import flash.display.Sprite; import flash.events.MouseEvent; public class I extends Sprite { private static var cSelector:Sprite; public static function $(selector:Sprite) { cSelector = selector return I; } public static function alpha(val:Number) { cSelector.alpha = val; return I; } // bind mouse event to the element public static function bind(EventStr,func:Function) { var func1:Function = function(e:MouseEvent){ func(cSelector); } // select the event from the list if(typeof(EventStr) == 'string'){ // map the events in lowercase var events:Object = {click:'CLICK',rollover:'ROLL_OVER',rollout:'ROLL_OUT',dblclick:'DOUBLE_CLICK',mousedown:'MOUSE_DOWN',mousemove:'MOUSE_MOVE',mouseout:'MOUSE_OUT',mouseover:'MOUSE_OVER',mouseup:'MOUSE_UP',mousewheel:'MOUSE_WHEEL'}; // check if the event exists in the list if(events[EventStr] &amp;&amp; MouseEvent[events[EventStr]]){ cSelector.addEventListener(MouseEvent[events[EventStr]],func1); } }else if(typeof(EventStr) == 'object'){ // add the event cSelector.addEventListener(EventStr,func1); } return I; } public static function remove() { cSelector.parent.removeChild(cSelector); return I; } } } </code></pre>

    1. COStatic proerties and methods are [bad practice](http://misko.hevery.com/code-reviewers-guide/flaw-brittle-global-state-singletons/) in an object-oriented language. To create a flent API, each method needs to return an object of the same type, that has the method. Check out the open-source Mockalate project for an example.

    3. COIt's not a good idea to try to shoehorn the language you're using into the metaphor you're used to (especially when large parts of that metaphor stem from the weaknesses, not the strengths, of that language). But if you can figure out how to use $ as a package or Class name, it will work as a namespace, which is how this works in JS. Alternatively, you can set your variable $ to a package or class.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
