warning (from warnings module): file "c:\python27\gui practice.py", line 19 app=wx.pysimpleapp() #this runs programme wxpydeprecationwarning: using deprecated class pysimpleapp.

import wx class main(wx.frame): def __init__(self,parent,id): wx.frame.__init__(self,parent,id, "my window", size=(300, 200)) panel=wx.panel(self) class panel_in_button(main): def __init__(self): button = wx.button(main.panel, label="exit",pos=(130,10), size=(60, 60)) self.bind(wx.evt_button, self.closebutton, button) self.bind(wx.evt_close, self.closewindow) def closebutton(self, event): self.close(true) def closewindow(self, event): self.destroy() if __name__=="__main__": app=wx.pysimpleapp() #this runs programme frame=main(parent=none, id=-1)#displays programme frame.show() app.mainloop()

you can't write code way. main class, not instance of class. shouldn't phone call class's method directly. instead, need instantiate , phone call object's method. no in code instantiate panel_in_button. anyway, don't recommend programming way. here's cleaned version:

import wx class main(wx.frame): def __init__(self,parent,id): wx.frame.__init__(self,parent,id, "my window", size=(300, 200)) panel=wx.panel(self) button = wx.button(panel, label="exit",pos=(130,10), size=(60, 60)) self.bind(wx.evt_button, self.closebutton, button) self.bind(wx.evt_close, self.closewindow) def closebutton(self, event): self.close(true) def closewindow(self, event): self.destroy() if __name__=="__main__": app=wx.app(false) #this runs programme frame=main(parent=none, id=-1)#displays programme frame.show() app.mainloop()

this combines 2 classes one. replaced reference wx.pysimpleapp deprecated. recommend take @ sizers instead of absolute positioning. sizers worth effort learn.
