Weight toggles define how the cell is acting when extra space
in the window is available.
Let's say selecting Weight X means that if there is
more space horizontally than required for the component
the cell will expand and occupy it.
Fill toggles define how the component is acting when extra space
in the cell is available.
Let's say selecting Fill H means that if there is
more space in the cell horizontally than required for the component
the component will expand and occupy it.
Anchor toggles define where the component is placed in the cell if
it is not occupying the whole cell space.
So Anchor values have effect only if Fill toggle is not set.

may help you to understand those toggles.
You need to open it with jvider, select OK button and play with
Fill and Anchor toggles. Other buttons are there just to keep the cell of
OK button expanded. Effect of Weight toggles you will see only when
resizing Test window.
