I think that applet shouldn't have methods like this, but there is enum  
Plasma::ItemStatus, maybe this could go there if needed?
I think that this method could be invoked internally when invoking applet  
global shortcut (menat to give focus, right?) and on mousepress (only if  
Plasma window is not active?), maybe other cases.
There could be of course both solution available, first "manual" focus  
request, and second auto focus.
It's better to do it behind scenes, easier to replace by better solution,  
if any found. ;-)
