How to create a tear off menu in TKinter. Help Needed

ishtar2020

Hi everybody

I'd appreciate some help on creating a tear off menu with TkInter. I've
been reading some documentation but still no luck.

Please don't get confused: when I mean "tear off" menu I don't mean a
drop-down or a pop-up menu, but those options which yield to another
batch of sub-options when scrolled over, (as for example, the File->New
option from internet explorer).

I'm sure TkInter supports those widgets because the IDLE editor is
built on it and it's got some tear off options like File->Recent Files.

Thank you all in advance

Are you sure you don't mean a cascading menu ? A tearoff menu gives the user the ability to tear off the menu into a new top level window.

The following example illustrates the difference:

from Tkinter import *
r = Tk()
m = Menu(r)

# Create a cascading Edit menu
editmenu = Menu(m, tearoff=0)
editmenu.add_co mmand(label='co py')
editmenu.add_co mmand(label='cu t')
editmenu.add_co mmand(label='pa ste')

# Create a sub menu of the edit menu and use tearoff option
testmenu = Menu(editmenu, tearoff=1)
testmenu.add_co mmand(label='op tion1')
testmenu.add_co mmand(label='op tion2')

# add the sub menu to the editmenu
editmenu.add_ca scade(label='te st', menu=testmenu)

# Add the edit menu to the menu bar
m.add_cascade(l abel='Edit', menu=editmenu)
# Display the menu
r.config(menu=m )

r.mainloop()

I created an extension for Tkinter which allows for popup menus (onesl
which appear when a parent menu item is under the cursor and close if
you then move away). It was an early experiment for me with Tkinter,
so I'm sure it can be heavily improved. It's available on

http://aspn.activestate.com/ASPN/Coo.../Recipe/442500

(see the notes, the demonstration program doesn't work correctly on
Windows, because I forgot the directory separator is a '\'. But the
code itself works to create cascading auto-pop-up menus, or any other
widget you want to pop-up as part of a menu.

Tkinter: disable menu items while running

by: Patrick L. Nolan | last post by:

We have a Tkinter application which has a menubar with cascade submenus. I would like to start the program with one of the submenu items state=DISABLED, then change it to state=NORMAL at a later time. I hope I just missed something obvious, because I can't figure out how to change its state. The problem comes about because the menu bar is built by several add_cascade() calls. Each of the cascades, in turn, has several add_command()...

Lazy cascading menu in Tkinter with postcommand

How to change menu text with Tkinter?

by: Phil Schmidt | last post by:

I am making a little Tkinter GUI app that needs to be in several languages (english, french, etc.), adjustable at runtime via a menu pick to select the language. The only way I can see to change text in the menus entries is to destroy them and recreate them usiing different labels. This seems very clunky though, and there must be a better way. Can anyone offer any pointers or a short example for how to do this? Thanks, Phil

Tkinter menu question--how to pass arguments

by: Kevin Walzer | last post by:

I'm having difficulty structuring a Tkinter menu entry. Here is the command in question: self.finkmenu.add_command(label='Update List of Packages', command=self.authorizeCommand(self.scanPackages)) When I start my program, it crashes because it's trying to run the command self.authorizeCommand. The reason I'm structuring it in this fashion is that this command takes another command as an argument--in this case, self.ScanPackages.
