The control size

size :ref:`percentage<RATIOVALUE> specification ` :

You can calculate the size of a control from a percentage of the size of its parent (often the window size).

SIZE = -16 + {50},16 + {20};

In this example it is set as the following.

width = window width - 16

height = window height + 16

The size default value

The default value is set when the size of the control was omitted or specify 0 .

The default value is the size of the texture parts.

If you want to display by dot-by-dot , you set to 0 or don’t set.
