A interactive area in a widget, specified by a circle.
The area may be added to a WImage or WPaintedWidget to provide interactivity on a circular area of the image. The circle is specified in pixel coordinates.
Usage example:
| Wt::WCircleArea::WCircleArea | ( | ) |
Default constructor.
Specifies a circular area with center (0, 0) and radius 0.
| Wt::WCircleArea::WCircleArea | ( | int | x, |
| int | y, | ||
| int | radius | ||
| ) |
Creates a circular area with given geometry.
The arguments are in pixel units.
