Contracting of filtering object                        
Take a look at our filtering object and try to diminish our image in order to get more useful space.

 What we could presently do, would be  to change “Not switch”  button in some way. We shall incorporate it into On/Off switches.

We shall use the possibility of having the right mouse click free. In this particular situation, the following should be observed:
            1)       The condition may be altered into “Not” condition only provided that one of the main switches (or both) is active;
            2)       In case of repeated activity (right mouse click), the negation of the previous condition will be performed;
            3)        “Not”  condition is common for the entire object.  

This is the given image of contracted object:

                   The play of switch enables us to move quickly form one filtering condition into another one.

Real filtering object                               
Up to now, we have been working only with drafts and sketches of our objects. It has to be given the aspiration of modern technology, that is, we need to make it alive by means of object oriented programming (OOP). From now onwards, we shall be utilizing and working on only the real object images. The illustration shows the example numerical type filtering object.

    This is the enlarged object image with all the descriptions of actions being introduced so far.
