Detailed Description

Provides generic meter widget for Plasma.

Analog and bar meters are supported.

Svgs can have following ids:

• background: Drawn first to the bottom background can be a FrameSvg
• label0, label1, ...: Rectangles mark the label places
• bar: Bar for the bar meter can be replaced with bar-active and bar-inactive FrameSvg
• pointer: Pointer for analog meter
• rotatecenter: Marks the place of pointer rotation center
• rotateminmax: Width and height of this object are the Min and Max rotate angles for the pointer
• foreground: Is drawn to top
