Buttons and Menu Items
VPGL Environment has facilities as below figure to;
- make new class,
- make new method,
- clear/delete displayed method,
- change size of grid
- shift grid contents.

NEW CLASS button
To make new user-defined class, press NEW CLASS BUTTON. Pressing this button opens following dialog to specify the new class metrics:
You should specify the new class name in “NEW CLASS NAME” field then press “Add Class” button will register new class to the system.

New method will be added to current selected class. Before you press this button, you should change class choice.
You should specify these information about new method;
1. the new method name,
2. definition grid size,
3. whether fire it on all input arrived or not,
4. number of input and direction,
5. and number of output and direction.
In above figure, the new method name is FOO, initial grid size is 3×3, this method will wait staring execution until all inputs are arrived, this method has two inputs arrived from top edge as input 0 and left edge as input 1, and has one output emits to bottom edge as output 0.
All spec expect for its method name can change anytime later.

Shrink
Choosing this menu item cut off the grids of current method, 7×7 to 5×5, or 5×5 to 3×3. Other condition makes it to do nothing. All grid position stay. THEREFORE, CUT-OFF TILES WILL BE DISCARDED. This operation can not undo.
