align wx.DrawCircle to the center of the frame

Question

Hi there I wanted to draw a circle at the center of the Frame. Is there anything like wx.Align_Center I can use with wx.DrawCircle Below is my code.

#!/usr/bin/python

# points.py

import wx
import random

class Points(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, size=(250, 150))

        self.Bind(wx.EVT_PAINT, self.OnPaint)

        self.Centre()
        self.Show(True)

    def OnPaint(self, event):
        dc = wx.PaintDC(self)
        dc.SetBrush(wx.Brush('RED'))
        dc.DrawCircle(20,20)


app = wx.App()
Points(None, -1, 'Test')
app.MainLoop()

Answer 1

Just get the size of the frame and then divide the width and the height by 2.

import wx
import random

class Points(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, size=(250, 150))

        self.Bind(wx.EVT_PAINT, self.OnPaint)

        self.Centre()
        self.Show(True)

    def OnPaint(self, event):
        w, h = self.GetClientSize()
        dc = wx.PaintDC(self)
        dc.SetBrush(wx.Brush('RED'))
        dc.DrawCircle(w/2,h/2, 20)


app = wx.App()
Points(None, -1, 'Test')
app.MainLoop()

That will get you pretty close. You might need to tweak the height a bit as I don't think GetSize accounts for the width of the System Menu (the top bar on all windows).
