【EXT-UploadDialog相关】求UploadDialog的各种参数解释

JScript code

Ext.onReady(function(){
var dialog = new Ext.ux.UploadDialog.Dialog({
    autoCreate: true,
    closable: false,
    collapsible: true,
    draggable: true,
    minWidth: 400,
    minHeight: 200,
    width: 400,
    height: 350,
    proxyDrag: true,
    resizable: true,
    constraintoviewport: true,
    title: 'File upload queue.',
    url: 'upload.asp',
    reset_on_hide: false,
    post_var_name: 'extfile',
    allow_close_on_upload: false
});

请问各位，在EXT-UploadDialog中的各种参数都是什么含义？
比如autoCreate，比如draggable与proxyDrag都是什么意思，只看英文意思看不明白啊。最好有相关的文档最好啦，在网上找的文档介绍的不全，只有这些：
Configuration.
Most configuration options are inherited from Ext.Window (see ExtJs docs). The added ones are:

url - the url where to post uploaded files.
base_params - additional post params (default to {}).
permitted_extensions - array of file extensions which are permitted to upload (default to []).
reset_on_hide - whether to reset upload queue on dialog hide or not (default true).
allow_close_on_upload - whether to allow hide/close dialog during upload process (default false).
upload_autostart - whether to start upload automaticaly when file added or not (default false).
post_var_name - uploaded data POST variable name (defaults to 'file').

事件的不需要啦，我只是想看各项参数的含义，急用啊，大家帮帮忙~~

    resizable: true, //窗体可以改变大小
    constraintoviewport: true, //窗体在viewport中可见
    title: 'File upload queue.',  //标题
    url: 'upload.asp', //上传的url

});
