The Graphics Device Interfacehttp://www.zetcode.com/wxpython/gdi/Figure: Custom PatternsBasic primitivesPointThe simplest geometrical object is a point. It is a plain dot onthe window.DrawPoint(int x, int y)This method draws a point at x, y coordinates.#!/usr/bin/python# points.pyimport wximport randomclass 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)18 de 44 27/04/2008 1:08
The Graphics Device Interfacehttp://www.zetcode.com/wxpython/gdi/def OnPaint(self, event):dc = wx.PaintDC(self)dc.SetPen(wx.Pen('RED'))for i in range(1000):w, h = self.GetSize()x = random.randint(1, w-1)y = random.randint(1, h-1)dc.DrawPoint(x, y)app = wx.App()Points(None, -1, 'Points')app.MainLoop()A single point might be difficult to see. So we create 1000points.dc.SetPen(wx.Pen('RED'))Here we set the colour of the pen to red.w, h = self.GetSize()x = random.randint(1, w-1)The points are distributed randomly around the client area ofthe window. They are also distributed dynamically. If we resizethe window, the points will be drawn randomly over a newclient size. The randint(a, b) method returns a random integerin range [a, b], e.g. including both points.Figure: drawing pointsCross HairCross Hair is a vertical and horizontal line the height and widthof the window. It is centered on the given point.19 de 44 27/04/2008 1:08
