I've created a short test program that uses tkFileDialog.askdirectory
to help the user input a path into a tk entry widget. The problem I'm
having is that when I run the code as listed below, the getPath
function is called when the program initially runs, not when the button
is pressed.
from Tkinter import *
import tkFileDialog
class App:
def __init__(self, master):
frame = Frame(master)
frame.pack()
t = StringVar()
self.entry = Entry(frame, textvariable=t)
self.entry.pack(side=LEFT)
self.button = Button(frame, text="Select", fg="red")
self.button["command"] = self.getPath(t)
self.button.pack(side=LEFT)
def getPath(self, t):
dirPath = tkFileDialog.askdirectory(initialdir="c:\\")
print dirPath
t.set(dirPath)
root = Tk()
app = App(root)
root.mainloop()
The problem arises when I try to pass the t variable in the "command"
option of the button widget. If I set the command to
"command=self.getpath" rather than "command=self.getpath(t)", then I
don't get this issue. But I would like to be able to pass a variable
to the the function through the command option. I'm a Tk newbie ....
what am I doing wrong?
