I am planning a Python application with the following library:
opencv
tkinter
(originally Pygame was planned but there are problems with Tkinter on MAC M1 (Monterey) )
What I want to realize is a Tkinter window as root app with the possibility to control an opencv window (with running video).
The two windows are already running (and yes - I am aware that imgshow blocks the root app with a waitkey).
I know that I can cancel the imgshow loop with a key - but my problem is that the opencv window closes (and the Tkinter root app gets the focus again).
Important is: I need the possibility that the opencv window (black screen) stays open (fullscreen on a second monitor).
The basic functionality is that I want to send commands from the Tkinter window to the opencv window.
I am not really a pro in Python - maybe someone can help me with some approaches or give me hints in a possible direction (threading, multiproccess ? ).
Thanks a lot for your help!!!
I have built a simple GUI in tkinter that goes through an algorithm to fit Radial Velocity data. Everything works fine in Spyder, however when I try to run the file in command prompt the GUI's dimensions change drastically. This is how it is supposed to look and how it looks in Spyder. This is how it looks when it's run in command prompt. The plots that are produced show the same behavior described. I've tried setting all the windows in Tkinter so that they are unable to be resized. I'm not sure what else to try. Is there a way to fix this? I am on Windows 10 64bit, Python 3.5.4, and Spyder 3.2.5.
I found out what the problem was. It's due to the fact that Spyder automatically overrides high DPI scaling, whereas both Python.exe and Pythonw.exe do not. The solution was to check the 'Override High DPI Scaling behavior' option under the compatibility tab for both python.exe and pythonw.exe.
I want to minimize the main window of a C#/Eto app and switch to another program. But when a timer in the Eto app fires it opens a new window, which I want to see. It should be displayed on top of all other windows currently open. The focus may switch to that window, but it's ok if not.
Using BringToFront() of the Form class does not work.
What else could I do?
Due to the way Apple made OS X, you are unable to make a window go to the top with programming. On Windows it is different.
Good luck!
I'm trying to make a code editor (like gedit) in Python + Gtk3. On gedit there is a handle for the files view that is extended to the headerbar, any idea how to make something like that?
Check this image to see what I mean.
Is there a way to clear the "Run" console in PyCharm?
I want a code that delete/hide all the print() made previously.
Like the "clear_all" button, but without having to press it manually.
I have read that there is a way to do it in a terminal with os.system("cls"), but in PyCharm, it only adds a small square without clearing anything.
Also, I don't want to use print("\n" *100) since I don't want to be able to scroll back and see the previous prints.
In Pycharm:
CMD + , (or Pycharm preferences);
Search: "clear all";
Double click -> Add keyboard shortcut (set it to CTRL + L or anything)
Enjoy this new hot key in your Pycharm console!
Pycharm Community Edition 2020.1.3
You can right click anywhere above the current line on the console, and choose the "Clear All" option. It'll clear the console
How to
Download this package https://github.com/asweigart/pyautogui. It allows python to send key strokes.
You may have to install some other packages first
If you are installing PyAutoGUI from PyPI using pip:
Windows has no dependencies. The Win32 extensions do not need to be
installed.
OS X needs the pyobjc-core and pyobjc module installed (in that
order).
Linux needs the python3-xlib (or python-xlib for Python 2) module
installed.
Pillow needs to be installed, and on Linux you may need to install additional libraries to make sure Pillow's PNG/JPEG works correctly. See:
Set a keyboard shortcut for clearing the run window in pycharm as explained by Taylan Aydinli
CMD + , (or Pycharm preferences);
Search: "clear all"; Double click ->
Add keyboard shortcut (set it to CTRL + L or anything)
Enjoy this new hot key in your Pycharm console!
Then if you set the keyboard shortcut for 'clear all' to Command + L use this in your python script
import pyautogui
pyautogui.hotkey('command', 'l')
Example program
This will clear the screen after the user types an input.
If you aren't focused on the tool window then your clear hot-key won't work, you can see this for yourself if you try pressing your hot-key while focused on, say, the editor, you won't clear the embedded terminals contents.
PyAutoGUI has no way of focusing on windows directly, to solve this you can try to find the coordinate where the run terminal is located and then send a left click to focus, if you don't already know the coordinates where you can click your mouse you can find it out with the following code:
import pyautogui
from time import sleep
sleep(2)
print(pyautogui.position())
An example of output:
(2799, 575)
and now the actual code:
import pyautogui
while True:
input_1 = input("?")
print(input_1)
pyautogui.click(x=2799, y=575)
pyautogui.hotkey('command', 'l')
Easy Method:
Shortcut: Control K,
Right click on terminal and clear Buffer
There's also another way of doing it using the system class from os. All you need to do is have this code:
from os import system, name
# define our clear function
def clear():
# for windows the name is 'nt'
if name == 'nt':
_ = system('cls')
# and for mac and linux, the os.name is 'posix'
else:
_ = system('clear')
# Then, whenever you want to clear the screen, just use this clear function as:
clear()
However, in order for this functionality to work in pycharm, you need to enable "Emulate terminal in output console". You can find this under edit configuration of the file where you want to use the clear function, then it's under Execution option. Here's a screenshot: pycharm screensho
You could just do a ("\n" * 100000000), so it'll be impossible to scroll back.
In PyCharm terminal you can type 'cls' just like in linux terminal.
For Python Console (where you see the output) assign a shortkey for "clear all" in File -> Settings -> Keymap -> Other -> "Clear all"
You can also click somewhere on the PythonConsole -> Right button -> clear.
Hope it helps
I just relised that instead of going to the trouble of setting up a shortcut, you could just set up a command using PyAutoGUI to click on the trash bin on the side of the window e.g
note, to install pyautogui click on the end of the import pyautogui line, then press alt+enter and click install pyautogui.
import pyautogui
# to find the coordinates of the bin...
from time import sleep
sleep(2) # hover your mouse over bin in this time
mousepos = pyautogui.position() gets current pos of mouse
x,y = mousepos # storing mouse position
print(mousepos) # prints current pos of mouse
# then to clear it;
pyautogui.click(x, y) # and just put this line of code wherever you want to clear it
(this isn't perfect thanks to the time it takes to run the code and using the mouse, but it is reasonable solution depending on what you are using it for.)
I hope this answer is helpful even though this is an old question.
Just click the trash can icon to the left of the command window and it clears the command history!
In PyCharm 2019.3.3 you can right click and select "Clear All" button.This is deleting all written data inside of the console and unfortunately this is manual.
Sorry to say this, here the main question is how to do it programmatically means while my code is running I want my code to clear previous data and at some stage and then continue running the code. It should work like reset button.
After spending some time on research I solved my problem using Mahak Khurmi's solution https://stackoverflow.com/a/67543234/16878188.
If you edit the run configuration you can enable "emulate terminal in output console" and you can use the os.system("cls") line and it will work normally.
Iconman had the easiest answer.
But simply printing "\n" * 20 (or whatever your terminal height is) will clear the screen, and the only difference is that the cursor is at the bottom.
I came here because I wanted to visually see how long each step of a complex process was taking (I'm implementing a progress bar), and the terminal is already full of scrolling logging information.
I ended up printing ("A" * 40) * 20, and then "B" and "C" etc., and then filming it. Reviewing the video made it easy to see how many seconds each step took. Yes I know I could use time-stamps, but this was fun!
