I need a simple info box to display some status output, that I would alternatively dump to the console using print
. The easiest possibility that I found is the following:
import Tkinter as tk
root = tk.Tk()
root.withdraw()
from tkMessageBox import showinfo
showinfo('some caption', 'some info')
The only problem with this implementation is that my program (not written in Tkinter) will not continue running, until the 'ok' button of the showinfo
messagebox is pressed. That is, the showinfo
dialog will block.
Therefore my question: Is there a simple way to make showinfo
non-blocking? Are there alternative messagebox implementations in Tkinter that are non-blocking? I can think of the typical use-cage of showing a help page - the window should open and the main program keeps on running normally.
EDIT1: here's a simple help window that I came up with, but unfortunately it doesn't show up, unless I launch a different tkMessageBox
or a similar object:
class TextInfo(object):
def __init__(self, parent, window_title = 'window', textfield = 'a text field', label = None):
self.top = tk.Toplevel(parent)
self.parent = parent
self.window_title = window_title
self.textfield = textfield
# set window title
if window_title:
self.top.title(window_title)
# add label if given
if label:
tk.Label(self.top, text=window_title).grid(row=0)
# create the text field
self.textField = tk.Text(self.top, width=80, height=20, wrap=tk.NONE)
if textfield:
self.textField.insert(1.0, textfield)
self.textField.grid(row=1)
# create the ok button
b = tk.Button(self.top, text="OK", command=self.ok)
b.grid(row=2)
def ok(self):
self.top.destroy()
And this is how I call the window:
root = tk.Tk()
root.withdraw()
TextInfo(self.root, window_title, textfield, label)
# don't call root.mainloop() here, because this will lead to blocking.
Is there some kind of property or event that I need to set for the window to show up? If I call root.mainloop()
the window will show up, but then my GUI is blocked again.
