No preventHeader for window in 4.1 version?

[netemp]

In version 4.0.7 of ExtJs, we had a config "preventHeader" which could be set to false if we did not want header at the window.

But this seems to be no more available in version 4.1 - http://docs.sencha.com/ext-js/4-1/#!....window.Window

Thus, what is the new way to avoid header from being displayed in a window in version 4.1?

Thanks in advance for any help.

Seems to be the solution present here - http://docs.sencha.com/ext-js/4-1/#!/api/Ext.panel.Panel-cfg-header

Hope this helps someone looking for same.
