  Constructs composite view

Method Detail

### add

    public void add(View v, int mode)

  Adds element with insets coordinates ( 0,0 )
  Parameters:
    v
    mode
  See Also:
    add(ru.biosoft.graphics.View,int,java.awt.Point)

### add

    public void add(View v, int mode, Point insets)

  Adds new elements and arrange them relative the previous objects.
  Parameters:
    v - specified View
    mode - mode to arrange new element relative previous: Abrevations:

        X_RL
        | ||
        | |--- boundary of new element
        | ---- boundary of minimal rectangle, described all
        |      previous elements
        ------ x or y coordinate

        X - the x coordinate:
        L - left boundary of the object

        Special:
        UN  - don't change the corresponding x or y boundory of new element.
