Fields

Note: All coordinates are in pixels, relative to top-left corner of the window. All angles are in degrees.

• ↖ double x; // x coordinate (px)
• ↖ double y; // y coordinate (px)
• ↖ double r; // rotation (degrees) - around axis point
• ↖ double s; // scale - around axis point
• ↖ double w; // width (px)
• ↖ double h; // height (px)
• ↖ double alignX; // horizontal alignment offset - use Align() to set these
• ↖ double alignY; // vertical alignment offset
• ↖ double axisX; // horizontal axis offset - use SetAxis() to set these
• ↖ double axisY; // vertical axis offset
• ↖ bool active; // indicates whether object should be active/visible
• color color1; // inside (center) color of the circle
• color color2; // outside (edge) color of the circle
• double sectorStart; // sector start (0...1 range)
• double sectorSize; // sector size (0...1 range). Leave this at 1.0 to draw a fill circle.
• UINT divisions; // number of divisions on the circle; more = smoother appearance, less = better performance

Constructors

• geCircle( double _x=0, double _y=0, double _w=0, double _h=0, UINT divisions=32, double _sectorSize=1 );
• geCircle( const geCircle& original ); // copy constructor

Methods

• ↖ virtual void Align( int alignment = GE_ALIGN_TL, double _alignX = 0, double _alignY = 0 );
• ↖ virtual void SetAxis( int axis = GE_ALIGN_CENTER, double _axisX = 0, double _axisY = 0 );
