    import wx  class mainwindow(wx.frame):      def __init__(self,parent,id,title):       wx.frame.__init__(self,parent, wx.id_any, title, size = (1200,600), style=wx.default_frame_style|wx.no_full_repaint_on_resize)        sizermain = wx.gridbagsizer(3, 2)       self.sizermain = sizermain              pnl = wx.panel(self)        cmd1 = wx.button(pnl, label='aaaaa')       cmd2 = wx.button(pnl, label='bbbbbb')       cmd3 = wx.button(pnl, label='ccccc')       cmd4 = wx.button(pnl, label='dddd')        imgsizer = wx.boxsizer(wx.horizontal)        image = wx.bitmap('test.png',wx.bitmap_type_png)       img = wx.staticbitmap(self, -1, image)       imgsizer.add(img, flag=wx.left, border=10)        sizermain.add(imgsizer, pos=(0,0), span=(1, 3), flag=wx.top|wx.left|wx.right, border=10)       sizermain.add(cmd1, pos=(2,2), flag=wx.top|wx.left|wx.right, border=10)       sizermain.add(cmd2, pos=(1, 0), flag=wx.top|wx.left|wx.right, border=10)       sizermain.add(cmd3, pos=(1, 1), flag=wx.top|wx.left|wx.right, border=10)       sizermain.add(cmd4, pos=(2, 1), flag=wx.top|wx.left|wx.right, border=10)       pnl.setsizer(sizermain)        pnl.layout()       pnl.fit()        self.show(true)      def closewindow(self, event):         self.close()  class myapp(wx.app):     def oninit(self):         frame = mainwindow(none, -1, "test gridbag")         frame.centre()         self.settopwindow(frame)         return true  # declare application , start main loop app = myapp(0) app.mainloop()

the parent of wx.staticbitmap "img" needs panel "pnl". not "self".
