Question

I’ve got two frames – mainWindow, which is the “primary” frame, and moreWindow, which is a child of mainWindow. I’d like to show moreWindow when a button in mainWindow is clicked. Here’s what I’m trying:

def showChild(nil):
    moreWindow.Show()
class mainWindow(wx.Frame):
    def __init__:
        buttonMore.Bind(wx.EVT_BUTTON, showChild)
class moreWindow(wx.Frame):

TypeError: unbound method Show() must be called with moreWindow instance as first argument (got nothing instead)

I tried using moreWindow.Show(moreWindow), and that just gave a more cryptic error.

Answer 1

you need to call that method on an instance of moreWindow, not class moreWindow itself. That is, you need to create an instance of moreWindow somewhere in your code:

more_window = moreWindow()

And then call show on that instance:

more_window.show()

Also, check this answer, it’s exactly what you want to do:
