如何从Extjs 4.1中使用组件查询从组件获取插件? [英] How to get plugin from component using component query on Extjs 4.1?
问题描述
我想在Controller上添加事件监听器到插件。 http://docs.sencha.com/ext-js/4-1/#!/api/Ext.app.Controller 使用组件查询获取插件似乎与普通组件不同。
是否可以使用组件查询从组件获取插件?
I want to add event listener to plugin on Controller.like http://docs.sencha.com/ext-js/4-1/#!/api/Ext.app.Controller It seems different to get plugin using component query than normal component. Is it possible to get plugin from component using component query?
这是我的组件
Ext.define('App.view.file.List',{
rootVisible: false,
extend:'Ext.tree.Panel',
alias:'widget.filelist',
viewConfig: {
plugins: {
ptype: 'treeviewdragdrop',
allowParentInsert:true
}
},
//etc ...
我可以得到 treeviewdragdrop 插件使用组件查询,如
Can i get treeviewdragdrop plugin using component query like
Ext.define('App.controller.FileManagement', {
extend:'Ext.app.Controller',
stores:['Folder'],
views:['file.List','file.FileManagement'],
refs:[
{ ref:'fileList', selector:'filelist' }
],
init:function () {
this.control({
'filelist > treeviewdragdrop':{drop:this.drop} // <-- here is selector
});
},
// etc ....
推荐答案
你不能因为插件不是组件,所以没有选择器会找到它。
You can't because a plugin is not a component, thus no selector will find it.
另外,drop事件被树视图触发,所以树视图真的是你想要挂钩的。
Also, the drop event is fired by the treeview, so the treeview is really what you want to hook to.
这将工作:
init:function () {
this.control({
'filelist > treeview': {drop:this.drop}
});
},
