Inheritance diagram for wxGraphicsPath:

Detailed Description

A wxGraphicsPath is a native representation of a geometric path.

The contents are specific an private to the respective renderer. Instances are reference counted and can therefore be assigned as usual. The only way to get a valid instance is by using wxGraphicsContext::CreatePath() or wxGraphicsRenderer::CreatePath().

Library: wxCore

virtual void wxGraphicsPath::AddArc	(	wxDouble	x,
		wxDouble	y,
		wxDouble	r,
		wxDouble	startAngle,
		wxDouble	endAngle,
		bool	clockwise
	)		`[virtual]`

Adds an arc of a circle.

The circle is defined by the coordinates of its centre (x, y) or c and its radius r. The arc goes from the starting angle startAngle to endAngle either clockwise or counter-clockwise depending on the value of clockwise argument.

The angles are measured in radians but, contrary to the usual mathematical convention, are always clockwise from the horizontal axis.
