I posted a similar question a while ago but haven't received any answers so i thought i might ask a more generic question:
Does anyone know how to, through any means, output true video, not a rapidly changing sequence of images, in a Tkinter window with python?
You probably need an extension like TkVideo or Quicktime to do that, not sure there is a python style wrapper for it available yet.

I know that this might sound weird, but I have a problem considering the screen resolution of my Tkinter program. I have attached two pictures for a comparison.
I think you can clearly tell, what I'm talking about. The problem is that I don't really know why this happened. Suddenly the tkinter window had a way better resolution as you can see in the top picture. I did not change anything related to screensize/resolution by myself and was therefore expecting Tkinter to have published an update which just has better textures for every widget.
But because I had to reinstall python and all its modules this is no longer the case and the widgets look very blurry again (Bottom picture). Now I'm asking myself whether this has something to do with another version of Python or tkinter I'm using or what else could have been the reason for that.
I did not change my PC, Screen or anything like that. I just reinstalled python and its modules. Sadly I don't have the source code of the version where it looked great, but only an .exe file, because im continuously updating my program. But as I said before, I don't know what I could have changed which led to this huge resolution improvement.
I hope you get, what I'm trying to tell you.
Thanks in advance!
I was able so solve it!
I had a look on this question: on Stackoverflow
The answer from #binaryfunt solved my problem completely. So it was not really a tkinter/python thing, but rather windows itself.
I am using MATLAB and SIMULINK and there is something missing there that is driving me crazy, but the question is not MATLAB-related.
At a certain point I have a window like that:
I would like to have the SELECT ALL button. I don't know why, but since a lot of years I am asking this feature to MathWorks but they don't implement it.
Anyway, I decided to do a workaround by myself.
I want to make a small script in Python which detect the text 'Tunable' and after it clicks automatically on ALL the checkboxes.
Is it possible to do it in Python ?
I found a solution to my problem.

I am happy to share ideas and to know your opinion.
I am thinking of writing a python program that runs in the background and can inspect user's GUI events.
My requirements is very simple:
1) When user right click the mouse, it can show an option; and when this option is chosen, my program should know this event.
2) When user select a file and click some predefined key combination, my program should know this event.
What should I do? Is this a GUI program? I am also thinking that, this program maybe a daemon on the machine and can inspect the user's GUI event, but I am not sure how can I do this.
Thanks.
If you're talking about doing this stuff inside of a wxPython program, then it's all pretty simple. There's a PopupMenu widget for the first one and an AcceratorTable for the second one. If you're wanting to catch mouse and keyboard events outside of a wxPython program, then you have to go very low-level and hook into the OS itself, which means that there really isn't any good way to do it cross-platform. You'll probably want to look at ctypes and similar libraries for that sort of thing.
I've been researching this problem a bit and while I don't have a definite answer, I thought it would be good to share what I found.
First, according to the answers for this question, wxPython cannot track nor control the mouse position outside of the area controlled by the wxPython app. However, as we can see in the answers to this question, under certain circumstances it may be possible to create system-wide hot keys that wxPython can see (although we can also see that this is probably not the optimal solution).
So what will work for the OP? Well, build a cross platform application that does what the OP wants seems almost impossible so I will assume the OP is developing for MS Windows. Following the suggestions in those previous two questions, I looked into the PyWin32 API. It's a little hard to find documentation for it but this question offers some helpful links. A little more digging and I found this tutorial for system-wide hotkeys as well as the win32event.WaitForMultipleObjects and win32event.WaitForSingleObject methods which, if the OP can figure out the proper event, may be what the OP needs to catch menu clicks.
I know it's far from a complete answer but hopefully this can serve as a good jumping-off point for further research.
Beginner python learner here. I have a question that I have tried to Google but I just can't come up with the proper way to ask in just a few words (partly because I don't know the right terminology.)
How do I get python to detect other widgets? For example, if I wanted a script to check and see when I click my mouse if that click put focus on an entry widget on a (for example) website. I've been trying to get it to work in Tkinter and I can't figure out even where to begin.
I've seen this:
focus_displayof(self)
Return the widget which has currently the focus on the
display where this widget is located.
But the return value for that function seems to be some ambiguous long number I can't decipher, plus it only works in its own application.
Any direction would be much appreciated. :)
Do you mean inside your own GUI code, or some other application's/website's?
Sounds like you're looking for a GUI driver, or GUI test/automation driver. There are tons of these, some great, some awful, many abandoned. If you tell us more about what you want that will help narrow down the choices.
Is this for testing, or automation, or are you going to drive the mouse and button yourself and just want something to observe what is going on under the hood in the GUI?
>How do I get Python to detect other widgets?
On a machine, or in a browser? If in a machine, which platform: Linux/Windows (which)/Mac?
If in a browser, which browser (and major version)?
> But the return value for that function seems to be some ambiguous long number I can't decipher
Using longs as resource handles is par for the course, although good GUI drivers also work with string/regex matching on window and button names.
> plus it only works in its own application.
What do you mean, and what are you expecting it to return you? You should be able to look up that GUI object and access its title. Look for a GUI driver that works with window and button names.
Here is one list, read it through and see what sounds useful. I have used AutoIt under Win32, it's great, widely-used and actively-maintained; it can be called from Python (via subprocess).
Here are comparisons by the author of PyWinAuto on his and similar tools. Give a read to his criticisms of its structure from 2010. If none of these is what you want, at least you now have the vocabulary to tell us what would be...
