Detailed Description

Custom rotary widget.

The background image - for Rotary::Type::Normal and Rotary::Type::Center - as well as the knob is loaded via a SVG image. The arc indicating the current value will the painted within Qt.

Normal

The arc is of solid red color.

Center

The arc features a point at its upmost position.

If set by the user, it shows a green color. If another value is used, a grey and smaller dot will be displayed instead.

Small

No arc will be drawn.
