I have a long running application with a Tkinter GUI.
Is there a way to see how many events are pending in the queue?
I want my application to occasionally process events (so that the
output window will update; the root window will refresh if
the user moves it; etc.).
I tried using Tk.tk.dooneevent(), but it blocks if no events are
available. What I thought of doing is calling a method that
does something like this:

I have an Entry widget inside a Frame. The Frame contains other
widgets as well. I have bound the <Key> event to the Frame, but I
don't want the Frame to receive the event when the Entry widget has
focus.
So, I bound the <Key> event to the Entry widget (bound to method
a_key()). This works, except that both the Entry and Frame widgets get
the event. This also forces me to implement event handlers, which is
fine for the Frame since...

I'm confused about how to use the update_idletasks method. In my
program, I have a handler for a button in which execution will linger.
During that time, I would like for the GUI to continue to show signs of
life. I have a Pmw MessageBar in which I display a status message. I
figured out that if I run update_idletasks on that MessageBar, then the
MessageBar will update the display as I update the message. However,
if I cover the GUI...

My project uses Python-2.3.4 + Tkinter + PIL-1.1.4 to retrieve images
from server and display those images.
I created a thread (also a separate toplevel window) for displaying
images and another thread for recording the frame rates (using a
progress bar for visulization). The whole application worked very well
once it received image data from the socket.
The problem is when I tried to close that display window (click on the

Hello,
I'm a beginner with Python and Tkinter development.
My application parse links in an html file. And I use Tkinter to
implement a GUI. This GUI has a button to launch the parse treatment,
and a status bar to show the state of the treatment.
I know that because of the mainloop, my tkinter application freeze
while my treatment isn't finished. That's why my status bar doesn't
update herself in real time.
I wanted to use the after or...

hi people.
when i create a widget, such as a toplevel window, and then i destroy
it, how can i test that it has been destroyed? the problem is that even
after it has been destroyed, the instance still exists and has a tkinter
name, so testing for None is not feasible:
>>> import Tkinter
>>> fin = None
>>> fin1 = Tkinter.Toplevel()

Hi there,
I've got a tree control in Tkinter (using the ESRF Tree module) but I
can't get it to layout how I want it.
I'd like to have it so that it streches north/south (anchored to the top
and bottom), is of a fixed width and is anchored to the left hand side.
Here's my code (its derived from one of the examples from the ESRF web
site):

I am struggling to get the pack method to do what I intend.
I am trying to display user input in a seperate window, along with
a little description of the field, something like this:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
