Ext.Action
action实现一个脱离了容器的事件,所有它可以在多个容器之间共享,不过好象只有Ext.Toolbar, Ext.Button 和 Ext.menu.Menu支持action接口:),因为容器要实现下面所有的方法setText(string), setIconCls(string), setDisabled(boolean), setVisible(boolean) and setHandler(function)
方法:
Action( Object config )
构造,config定义为{
disabled : Boolean,//禁止使用
handler : Function,//事件句柄
hidden : Boolean,//隐藏
iconCls : String,//样式类
scope : Object, //handler将在哪个范围内执行
text : String //文本
}
disable() : void
enable() : void
setDisabled( Boolean disabled ) : void
禁止/允许
each( Function fn, Object scope ) : void
为每个实现了此action的componet应用fn
hide() : void
show() : void
setHidden( Boolean hidden ) : void
显示/隐藏
setHandler( Function fn, Object scope ) : void
setIconClass( String cls ) : void
setText( String text ) : void
重新设置config配置的属性值
示例:
Ext.widgets-Button,SplitButton,CycleButton 
Ext.widgets-Button,SplitButton,CycleButton var action = new Ext.Action(...{
Ext.widgets-Button,SplitButton,CycleButton text: 'Do something',
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton handler: function()...{
Ext.widgets-Button,SplitButton,CycleButton Ext.Msg.alert('Click', 'You did something.');
Ext.widgets-Button,SplitButton,CycleButton },
Ext.widgets-Button,SplitButton,CycleButton iconCls: 'do-something'
Ext.widgets-Button,SplitButton,CycleButton });
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton var panel = new Ext.Panel(...{
Ext.widgets-Button,SplitButton,CycleButton title: 'Actions',
Ext.widgets-Button,SplitButton,CycleButton width:500,
Ext.widgets-Button,SplitButton,CycleButton height:300,
Ext.widgets-Button,SplitButton,CycleButton tbar: [
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton //将action做为一个菜单按钮添加到工具栏
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton action, ...{
Ext.widgets-Button,SplitButton,CycleButton text: 'Action Menu',
Ext.widgets-Button,SplitButton,CycleButton //将action做为文本选择项添加到menu
Ext.widgets-Button,SplitButton,CycleButton menu: [action]
Ext.widgets-Button,SplitButton,CycleButton }
Ext.widgets-Button,SplitButton,CycleButton ],
Ext.widgets-Button,SplitButton,CycleButton items: [
Ext.widgets-Button,SplitButton,CycleButton //由action构造button,添加到panel
Ext.widgets-Button,SplitButton,CycleButton new Ext.Button(action)
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton renderTo: Ext.getBody()
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton // 如果这儿setText.当然button/menu/toolbar中的action文本都变了
Ext.widgets-Button,SplitButton,CycleButton action.setText('Something else');
Ext.Button
简单的按钮类
公有属性:
disabled : Boolean
允许?
hidden : Boolean
隐藏?

按下?
方法 [继承来的忽略]
Button( Object config )
构造可选config{
clickEvent : String, //handler响应的事件,默认是click

Ext.SplitButton
上例中的带菜单按钮还不专业,于是有了Ext.SplitButton,专门为带有下拉菜单的按钮设计的
SplitButton( Object config )
构造,config中加入了{
arrowHandler : Function,
arrowTooltip : String
setArrowHandler( Function handler, [Object scope] ) : void
设置下拉箭头的点击事件
事件:
arrowclick : ( MenuButton this, EventObject e )
使用示例:
比如上例中的菜单按钮可以改为
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton function onItemCheck(item)...{
Ext.widgets-Button,SplitButton,CycleButton Ext.MessageBox.alert("点击事件",String.format("您选择了{0}",item.text));
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton function showMenu(obj)...{
Ext.widgets-Button,SplitButton,CycleButton Ext.MessageBox.alert("点击下拉",obj.getXTypes() )
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.QuickTips.init();
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton var button=new Ext.SplitButton(...{
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton arrowHandler : showMenu,
Ext.widgets-Button,SplitButton,CycleButton handler: onItemCheck,
Ext.widgets-Button,SplitButton,CycleButton arrowTooltip : "更多",
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.CycleButton
这是一个SplitButton的实用子类,用于在多个item之间切换状态,当然它也会带有menu可供选择,也可以直接点击按键在item之间切换
CycleButton( Object config )
构造,config新增配置项{
changeHandler : Function, //状态切换时的处理事件
items : Array, //items应该是menu item的数组
prependText : String, //前导text
showText : Boolean, //追加item的text到按钮显示
getActiveItem() : Ext.menu.CheckItem
setActiveItem( Ext.menu.CheckItem item, Boolean suppressEvent ) : void
得到/设置活动选项
toggleSelected() : void
切换选择项,相当于点击一次按钮
示例
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton new Ext.CycleButton(...{
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton showText: true,
Ext.widgets-Button,SplitButton,CycleButton prependText: 'View as ',
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton items: [...{
Ext.widgets-Button,SplitButton,CycleButton text:'text only',
Ext.widgets-Button,SplitButton,CycleButton iconCls:'view-text',
Ext.widgets-Button,SplitButton,CycleButton checked:true
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton },...{
Ext.widgets-Button,SplitButton,CycleButton text:'HTML',
Ext.widgets-Button,SplitButton,CycleButton iconCls:'view-html'
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton ...{
Ext.widgets-Button,SplitButton,CycleButton text:'XML',
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton changeHandler:function(btn, item)...{
Ext.widgets-Button,SplitButton,CycleButton Ext.MessageBox.alert('Change View', item.text);
Ext.widgets-Button,SplitButton,CycleButton Ext.widgets-Button,SplitButton,CycleButton 新增事件
change : ( Ext.CycleButton this, Ext.menu.CheckItem item )
Button还有两个子类,Ext.Toolbar.button,Ext.Toolbar.SplitButton,用法和Ext.buttom/Ext.SplitButton一样,只是它们仅适用于工具栏
