DwtColorPicker(parent, className, posStyle)
parent
- the widget parent, can be a DwtShell (or a DwtMenu????)
className
- the name of a css style class to be assigned to the widget
posStyle
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);
