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);
