946 * @class Ext.CycleButton
947 * @extends Ext.SplitButton
948 * A specialized SplitButton that contains a menu of {@link Ext.menu.CheckItem} elements. The button automatically
949 * cycles through each menu item on click, raising the button's {@link #change} event (or calling the button's
950 * {@link #changeHandler} function, if supplied) for the active menu item. Clicking on the arrow section of the
951 * button displays the dropdown menu just like a normal SplitButton. Example usage:
953 var btn = new Ext.CycleButton({
955 prependText: 'View as ',
964 changeHandler:function(btn, item){
965 Ext.Msg.alert('Change View', item.text);
970 * Create a new split button
971 * @param {Object} config The config object
974 Ext.CycleButton = Ext.extend(Ext.SplitButton, {
976 * @cfg {Array} items An array of {@link Ext.menu.CheckItem} <b>config</b> objects to be used when creating the
977 * button's menu items (e.g., {text:'Foo', iconCls:'foo-icon'})
980 * @cfg {Boolean} showText True to display the active item's text as the button text (defaults to false)
983 * @cfg {String} prependText A static string to prepend before the active item's text when displayed as the
984 * button's text (only applies when showText = true, defaults to '')
987 * @cfg {Function} changeHandler A callback function that will be invoked each time the active menu
988 * item in the button's menu has changed. If this callback is not supplied, the SplitButton will instead
989 * fire the {@link #change} event on active item change. The changeHandler function will be called with the
990 * following argument list: (SplitButton this, Ext.menu.CheckItem item)
993 * @cfg {String} forceIcon A css class which sets an image to be used as the static icon for this button. This
994 * icon will always be displayed regardless of which item is selected in the dropdown list. This overrides the
995 * default behavior of changing the button's icon to match the selected item's icon on change.
1000 * The {@link Ext.menu.Menu Menu} object used to display the {@link Ext.menu.CheckItem CheckItems} representing the available choices.
