Hi...

I followed the development of koffice for a few month now and decided to spend 
some time to help.
I started to look around in Karbon's code and got to the point where i could 
make some improvements to the layer view. But i got the following problem 
that seems to be too deep to change easily. The problem i have has to do with 
the state of the karbon objects (VObject derived classes).  It seems that the 
different possible states could not be combined to describe an complex object 
state. It is not possible to have an object that is locked and selected at 
the same time. So if one locks an object form the layer view and selects it 
from the document view, the object is not locked anymore. Some of these 
problems are coded around by using states like VObject::hidden_locked or 
VObject::normal_locked. 
So i propose to use a bitfield or something similar to describe the state of 
an object. So that one can set the state for instance to VObject::hidden | 
VObject::locked ot to VObject::locked | VObject::selected to combine 
different states. 
Cause setting and getting the state of an object is used all over the code, i 
ask you if this change is ok before putting any more effort into it.

Kind regards,
Jan Hambrecht
