Solution 1
import Tkinter as tk
root = tk.Tk()
mylist = ['a','b','c','d','e']
for i, x in enumerate(mylist):
label = tk.Label(root, text="Label "+str(i))
label.grid(row=i+1, column=1)
label.bind("<Enter>", lambda e, x=x: e.widget.config(text=x))
label.bind("<Leave>", lambda e, i=i: e.widget.config(text="Label "+str(i)))
root.mainloop()
Solution 2
Event functions can be included in a class and strings for displaying can be defined by a constructor.
import Tkinter as tk
class Labels(object):
def __init__(self,number,basicStr,onMouseStr):
self.i = number
self.basicStr = basicStr + str(number)
self.onMouseStr = onMouseStr
mylist=['a','b','c','d','e']
self.label = tk.Label(root,text="Label"+str(i))
self.label.grid(row=1+i,column=1)
self.label.bind("<Enter>", self.fun1)
self.label.bind("<Leave>", self.fun2)
def fun1(self,event):
self.label.config(text=self.basicStr)
def fun2(self,event):
self.label.config(text=self.onMouseStr)
root=tk.Tk()
labelsList = []
for i in range(5):
lab = Labels(i,"haha","label"+str(i))
labelsList.append(lab)
root.mainloop()

My objective is to change the text of label widget when the mouse move over the label.For one label i would do something like this:
import Tkinter as tk def fun1(event): label.config(text="Haha") def fun2(event): label.config(text="Label1") root=tk.Tk() label=tk.Label(root,text="Label1") label.grid(row=1,column=1) label.bind("<Enter>", fun1) label.bind("<Leave>", fun2) root.mainloop()
But now, i have a bunch of labels which is generated by for loop and a list which contains the text that i want to change.
mylist=['a','b','c','d','e'] for i in range(5): tk.Label(root,text="Label"+str(i)).grid(row=i+1,column=1)
This will generate 5 labels with numbers. Is it possible to add mouse over event for each individual label so that when i mouse over on the label 1, it changes to 'a', when i mouse over to label 2, it changes to 'b', etc? FYI, the number of items in the mylist will always be the same with the number used in for loop.

A. Rodas almost 11 years@ChrisAung It uses the actual
x
of the iteration for the lambda function. Otherwise, it will show "e" for all the labels.
