I've just done this tonight with this code:
[snip]
class GenericCallback:
def __init__(self, callback, *firstArgs):
self.__callback = callback
self.__firstArgs = firstArgs
def __call__(self, *lastArgs):
apply(self.__callback, self.__firstArgs + lastArgs)
[/snip]
[snip]
self.zone=Zones("D:\DAoC")
self.zonemenu = Menu(self.menubar, tearoff=0)
self.albionmenu=Menu(self.menubar, tearoff=0)
self.midgardmenu=Menu(self.menubar, tearoff=0)
self.hibernianmenu=Menu(self.menubar, tearoff=0)
for x in range(len(self.zone.locations)):
menuName=self.zone.locations[x][0]+" : "+self.zone.locations[x][1]
zoneNumber=int(self.zone.locations[x][0])
if zoneNumber<100:
self.albionmenu.add_command(label=menuName,
command=GenericCallback(self.zoneSelected, zoneNumber))
elif zoneNumber>100 and zoneNumber<200:
self.hibernianmenu.add_command(label=menuName,
command=GenericCallback(self.zoneSelected, zoneNumber))
elif zoneNumber>200 and zoneNumber<300:
self.midgardmenu.add_command(label=menuName,
command=GenericCallback(self.zoneSelected, zoneNumber))
self.zonemenu.add_cascade(label="Albion", menu=self.albionmenu)
self.zonemenu.add_cascade(label="Midgard", menu=self.midgardmenu)
self.zonemenu.add_cascade(label="Hibernia", menu=self.hibernianmenu)
self.menubar.add_cascade(label="Zone", menu=self.zonemenu)
[/snip]
[snip]
# Zone menu commands
def zoneSelected(self, zone):
print zone
[/snip]
make sense?
