Detailed Description

Number editor with individually controllable digits.

Each digit acts like a slider that can be scrolled up or down to increase or decrease the value of the number. The keyboard can also be used to edit the currently focused digit. The sign on the left side can be toggled by clicking it. The digits are scaled according to the dimensions of the view. The padding amount determines the spacing around the digits. For best looking characters use a Rect dimension ns x s where 'n' is the number of digits and 's' is the character size plus padding amount.
