A short while ago someone posted that(unlike the examples) you should use Tk as the base for your main window in tkinter apps, not Frame. Thus :
class MyMain(Frame): def __init__(self, master): self.root = master self.master=master self.createWidgets() def createWidgets(): ... root = Tk() app = MyMain(root) app.master.title("Object Editor") root.mainloop() would become: class MyMain(Tk): ... ... app = MyMain() app.title("My App") app.mainloop() When I try converting to this approach I run into a problem with the __init__() method. It appears to go into an infinite loop in tkinter.__getattr__(). If I omit __init__() I get a properly titled window, but must explicitly call my createWidgets method from __main__. class MyMain(Tk): createWidgets() ... ... app = MyMain() app.title("My App") app.createWidgets() app.mainloop() Am I missing something?
