从一个tkinter窗口打开另一个tkinter窗口

Question

I have a Tkinter window in the file gui.py. Upon the press of the Spacebar, I want to open another Tkinter window which is used to obtain an input from the user via the file imageinput.py.

So, I wrote the code to execute the run function of imageinput.py

def keyPressed(event, data):
    if event.keysym == "space": image_run()

When I run this, I get the following error:

What is the best way to open such another Tkinter window this way?

Answer 1

Without knowing more of your code, you would create a new "top level" widget and use that widget like you used the original root top level window ( root = tkinter.Tk() ) as the parent of whatever widget hierarchy you create. So...

def image_run(parent, *args, **kwargs):
    top = tkinter.Toplevel(parent)
    top.transient(parent)        
    canvas = tkinter.Canvas(top, ...)
    :
    :

Hope that helps!
