How to close ckfinder popup

Hi,

I use ckfinder (php) 2.0.1.
I have a site with several tabs (jquery).
In one tab, I put a button that launch the ckfinder in a popup.

My purpose is :
If the ckfinder popup is open and the user click on another tab in the main site, then the ckfinder popup is closed (programmatically) automatically.

There is a js method like 'ckfinder.closepopup();' ?
Or another method ?

Any help much appreciated.

Best regards.
