wxPython有没有办法画半圆

Question

Question is simple is there a way to draw half circle or pie using wxGraphicsContext ? I need to make something look like in the picture (this gauge is made in pyQt4).

EDIT: I did

    path = gc.CreatePath()
    path.AddArc(450, 100, 30, math.radians(180), math.radians(0))
    pen = wx.Pen('#ffffff', 1)
    #pen.SetCap(wx.CAP_BUTT)
    gc.SetBrush(wx.Brush('#CC7F32', wx.SOLID))
    gc.SetPen(pen)
    gc.DrawPath(path)

and I got this

How can I get full outline because now there is none at the bottom of the arc?

Answer 1

You can do it using AddArc() or, probably better in this particular case, AddArcToPoint() . As always, remember that you can fill any path by setting the brush corresponding to the desired background colour and calling FillPath() instead of just StrokePath() .

And to draw the segment, you should just call AddLineToPoint() directly: it's simple as you just need to give it the coordinates of your circle centre.
