DwtColorPicker(parent, className, posStyle)

parent

className

the name of a css style class to be assigned to the widget

Generates DwtSelectionEvent() on seletion. The hex RGB of the color seleted is found in the detail variable.

var colorCode = event.detail;

Overview

Creates a color picker displaying "Web safe" colours. Instances of this class may be used with DwtMenu to create a ColorPicker menu. Clicking on a color cell generates a DwtSelectionEvent the detail attribute of which contains the color string associated the cell on which the user clicked

Example

 function launch() {
   var DBG = new AjxDebug(AjxDebug.NONE, null, false);

   /* We always have to create a DwtShell as the root of our component
    * hierarchy and does some handy things for us.
    */
   var shell = new DwtShell("MainShell", false, null, null, true);

   /* Setting the shell to be virtual tells it that it should remain hidden.
    * Direct children of the shell will actually have their HTML elements
    * reparented to the body element. This is handy when we want to mix
    * components in with existing HTML content
    */ 
   shell.setVirtual();

   /* 
    * Now we will create a listener to handle the selection and the picker widget
    */
   var listener = new AjxListener(null, colorListener);
   var colorPicker = new DwtColorPicker(shell);

   // add the listener to the widget
   colorPicker.addSelectionListener(listener);

   // Get the div into which we want to place the picker
   var div = document.getElementById('primary_color_picker');

   // Clean out any content
   div.innerHTML = "";

   // Reparent the picker's HTML element to the div
   colorPicker.reparentHtmlElement(div);
 }

 function colorListener(event) {
   // just an alert box with the selected color number
   alert(event.detail);
 }

 // Make it happen
 AjxCore.addOnloadListener(launch);
