I have four images in a frame. I want to pop up a menu when the user right clicks on an image, and when they choose an option from the menu, execute the action.
I can create the popup menu, and bind it to the image. However, what I can't figure out is how to detect in the popup menu code which image fired the event so I can do the right thing (like display a larger version of the image, etc.)
# create a menu
self.popup = Menu(self.pictureWindow, tearoff=0)
self.popup.add_command(label="Change Picture", command=self.selectPicture)
self.popup.add_command(label="Make Primary", command=self.selectPicture)
self.popup.add_command(label="Large View", command=self.selectPicture)
self.picture1.bind("<Button-1>", self.do_popup)
def do_popup(self,event):
# display the popup menu
try:
self.popup.tk_popup(event.x_root, event.y_root, 0)
finally:
# make sure to release the grab (Tk 8.0a1 only)
self.popup.grab_release()
Thanks for the advice!
