phoenix_title wx.GraphicsPath

A wx.GraphicsPath is a native representation of a geometric path.

The contents are specific and 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 wx.GraphicsContext.CreatePath or wx.GraphicsRenderer.CreatePath .

AddArc Adds an arc of a circle.
AddArcToPoint Appends a an arc to two tangents connecting (current) to (x1,`y1`) and (x1,`y1`) to (x2,`y2`), also a straight line from (current) to (x1,`y1`).

class wx.GraphicsPath(GraphicsObject)

A GraphicsPath is a native representation of a geometric path.


Methods


AddArc(self, *args, **kw)

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.
