Do you mean about such like as TkWindow#grab or TkWindow#focus? 
Or usage of 'screen' option of TkToplevel widget?
Or again, how to control another {Ruby|Tcl}/Tk process on the
same or other machine with RemoteTkIp class?

Did you check samples in 'ext/tk/sample' directory 
on your ruby source tree?
