Thanks Francesco, Guilherme -
you've both given me plenty to experiment with (and learn :-)). I have a
'partial' solution to what I'm trying to achieve (code snippet below)
.........
self.menubar = Menu(self.frm)
# create the variable 'Action' sub-menu list
# each sub-menu entry will have an (on)value which
corresponds to it's DB tablename (self.tables[value - 1])
self.muVar=IntVar()
self.mnth_mu=Menu(self.menubar, tearoff=0)
self.on=IntVar()
x=0
# Strip out the month_yr part of the DB tablename (e.g.
04_April_09) and create a radiobutton entry on the
# menu for each table that currently exists - a table is
only created at the start of a month
for mnth in self.tables:
st=mnth.split("_",1)[1]
self.mnth_mu.add_radiobutton(label=st,
variable=self.muVar, value=self.on.get(), command=self.alt_cmd)
x+=1
self.on.set(x)
# create the 'Action' menu list
self.act_mu = Menu(self.menubar, tearoff=0)
self.act_mu.add_command(label="Low stock - closing less
monthly sales", command=self.low_stock)
self.act_mu.add_command(label="Profit and Loss",
command=self.pandl)
self.act_mu.add_cascade(label="Stock/Order History",
menu=self.mnth_mu)
self.act_mu.add_cascade(label="Top two sellers by quantity",
menu=self.mnth_mu)
self.act_mu.add_cascade(label="Top two earners",
menu=self.mnth_mu)
self.act_mu.add_cascade(label="Bottom two sellers by
quantity", menu=self.mnth_mu)
self.act_mu.add_cascade(label="Bottom two earners",
menu=self.mnth_mu)
self.menubar.add_cascade(label="Actions", menu=self.act_mu)
# display the menu
parent.config(menu=self.menubar)
........
def alt_cmd(self):
# Determine the selection, match it to the correct
tablename then call appropriate function to generate the sql
print self.muVar.get()
........
The issue is that all the 'Actions' after and including Stock/Order history
will display the same sub-menu (self.mnth_mu).
The code as it stands enables me to identify which month has been selected
for a particular 'Action' but not which 'Action' it refers to i.e. works
fine if self.mnth.mu is used only once.
A solution is to create a separate menu for each 'Action' - I am averse to
doing this because the sub-menu for each action that requires a sub-menu is
identical and yes I'm a bit of a lazy programmer!
I was hoping to - whatever the level of a menu - when a selection is made -
to be able to identify the 'Action' and the 'Month' selected.
I hope this makes sense ... I shall look into what you both have said
cheers
