ExtJS 4 - 获取 Ext.toolbar 的溢出菜单
有没有办法在具有 enableOverflow:true 的 Ext.toolbar 上获取分别用于溢出菜单和“更多按钮”的 Ext.menu 和/或 Ext.Button 组件？
我尝试将侦听器附加到工具栏的 overflowchange 事件，看看是否可以使用 query() 或 getComponent() 来查找按钮/菜单当它被显示时，但是当调整工具栏大小以导致溢出菜单出现/消失时，该事件似乎不会触发。我还监视了工具栏的 add 事件，以查看当“更多”按钮添加到工具栏时是否触发该事件，但也没有运气。
Is there a way to get the Ext.menu and/or the Ext.Button components used for the overflow menu and "more button" respectively on a Ext.toolbar that has enableOverflow:true?
I tried attaching a listener to the toolbar's overflowchange event to see if I could use query() or getComponent() to find the button/menu when it was being shown, but that event does not seem to fire when resizing the toolbar to cause the overflow menu to appear/disappear. I also monitored the toolbar's add event to see if that was fired when the "more" button was added to the toolbar, but no luck there either.

在 Sencha 论坛的帮助下弄清楚了：

溢出菜单组件位于：
toolbar.layout.overflowHandler.menu但请注意，
overflowHandler的menu属性仅在实际需要菜单时才出现。Figured it out, with help from the Sencha Forums:

The overflow menu component resides in:
toolbar.layout.overflowHandler.menuBe care though, the
menuproperty ofoverflowHandleris only present when the menu is actually needed.
