Maybe you are better off with a simple Motion event, you can access the
menu item under the mouse pointer through the menu's index() method
(from the menu manpage:
Many of the widget commands for a menu take as one argument an indicator
of which entry of the menu to operate on. These indicators are called
indexes and may be specified in any of the following forms:
(...)
@number
In this form, number is treated as a y-coordinate in the menu's
window; the entry closest to that y-coordinate is used. For example,
`...@0'' indicates the top-most entry in the window.
)
So, in this simple example, you will surely see the point:
################################
from Tkinter import *
root = Tk()
m = Menu(root)
m.add_command(label='foo')
m.add_command(label='bar')
m.add_command(label='blah')
root.bind('<3>', lambda event: m.tk_popup(event.x_root, event.y_root))
def callback(event):
try:
print m.entrycget(m.index('@%d' % event.y), 'label')
except TclError:
print 'this must have been the tearoff or something'
m.bind('<Motion>', callback)
root.mainloop()
################################
I hope this helps
