Tkinter, Toplevel and grid

Hi,
I'm trying to use a grid in a secondary window and failing.

Here is my code:

Code:

class TopLevelTest4: def NewWindow(self): self.root2 = Toplevel() self.grid = Frame(self.root1) self.grid.pack() self.canvas2 = Canvas(self.root2, width=200, height=200) self.canvas2.grid(in_=self.grid,row=0,column=0) self.canvas3 = Canvas(self.root2, width=200, height=200) self.canvas3.grid(in_=self.grid,row=0,column=1) self.root2.title("New Window") self.root2.mainloop() def __init__(self): self.root1 = Tk() self.canvas1 = Canvas(self.root1, width=400, height=200) self.canvas1.pack() self.menubar = Menu(self.root1) self.menubar.add_command(label="New Window",command=self.NewWindow) self.root1.config(menu=self.menubar) self.root1.title("TopLevelTest") self.root1.mainloop() TopLevelTest4()

and I get the following error:

Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python22\lib\lib-tk\Tkinter.py", line 1292, in __call__
return apply(self.func, args)
File "<source>", line 56, in NewWindow
File "C:\Python22\lib\lib-tk\Tkinter.py", line 1684, in grid_configure
self.tk.call(
TclError: can't put .27548696.27645416 inside .27572536
Script '<source>' returned exit code 0

Any ideas as to how I can sucessfully do this?

Thanks,
-Kalev

The problem could have something to do with not being able to use grid() and pack() together.. so use one or the other and it should work

hmm...
it seems to work fine as long as its using Tk() and not Toplevel()

as in:

Code:

class TopLevelTest3: def NewWindow(self): self.root2 = Toplevel() self.canvas3 = Canvas(self.root2, width=400, height=200) self.canvas3.pack() self.root2.title("New Window") self.root2.mainloop() def __init__(self): self.root1 = Tk() self.grid = Frame(self.root1) self.grid.pack() self.canvas1 = Canvas(self.root1, width=200, height=200) self.canvas1.grid(in_=self.grid,row=0,column=0) self.canvas2 = Canvas(self.root1, width=200, height=200) self.canvas2.grid(in_=self.grid,row=0,column=1) self.root1.title("TopLevelTest") self.menubar = Menu(self.root1) self.menubar.add_command(label="New Window",command=self.NewWindow) self.root1.config(menu=self.menubar) self.root1.mainloop() TopLevelTest3()

But, I'll see what I can do without depending on both.

Thanks,

Hi Kalev,

If I understand it:

Code:

self.canvas2 = Canvas(self.root2, width=200, height=200)
self.canvas2.grid(in_=self.grid,row=0,column=0)

Here you create a canvas object as a child of self.root2 but when you apply it's grid method , self.grid is a child of self.root1 which is a frame in the first window you created.
self.grid = Frame(self.root2)
solves the problem.
BTW I was confused

by the use of grid as an object and method.
