QUESTION
Is it possible to change the Input Keyboard Layouts by programmatically in Pyqt5?
My first and second text box accepts Tamil letters. IN Tamil So many keyboard Layouts available. By default in Windows 10, Tamil Phonetic, Tamil99 and Tamil Traditional Keyboards are available. Now I want to select Keybaord layouts programmatically...
For example. In My First textbox, I need to assign a "Tamil99" keyboard layout and in the second textbox, I need to assign a "Tamil Phonetic" keyboard layout. How to assign it, programmatically?
...ANSWER
Answered 2022-Mar-08 at 17:12So Qt doesn't offer this, but you can ask your OS to do it for you.
Assuming you're just looking at Windows, you can change the current keyboard layout in python using pywin32, which lets you easily access the Windows API from your script. Once installed into your Python environment you can
import win32api
and then use a call like win32api.LoadKeyboardLayout('00000809',1)
to set the layout (the values I've put here set it to UK English). The first parameter is a string representing the keyboard layout to use, and the second is a flag. See documentation.
I found this list of KLIDs (Keyboard Layout IDs), which shows two for Tamil keyboards. "00000449" is Tamil, "00020449" is Tamil 99. The 449 at the end means Tamil, and the two digits before set which subtype of Tamil keyboard to use (e.g. 20 for Tamil 99) - I can't find one for Tamil phonetic, but maybe you'll be able to find it.
You can set up your program to call these functions whenever you want it to switch keyboard (for example, when your user activates a specific text input box).
Also, if you want to check the current keyboard layout you can use win32api.GetKeyboardLayout(0)
(doc). Maybe you can use this to figure out what the IDs are for each of the Tamil keyboards you want to use. Mind that it returns an int for the locale id rather than a string.
Other useful keyboard related functions are win32api.GetKeyboardLayoutList()
(to find all the locales installed on the current machine), win32api.GetKeyboardLayoutName()
and win32api.GetKeyboardState
- documentation for all these can be found here.
QUESTION
What I want to do is to open a new Countrypage
sub-window by clicking on the "New" button which is in Countrypage
itself.
For example, if I click the "New" button in a CountryPage
window (window title: "Country page"), one more new Countrypage
window will be opened in the MDI area (window title: "Country Page 1"). Now if we click the "New" button in "Country Page 1", one more new window will open in the MDI area (window title: "Country page 2") and so on - and I want to close the windows one by one by pressing the corresponding "Close" button in Countrypage
. New window are opened only by pressing a "New" button.
And if we close the last opened window by pressing the "Close" button, the text item in the "Country" text-box will be automatically updated in the previous window's "Country" text-box and so on.
Main Script :
...ANSWER
Answered 2022-Feb-14 at 18:38The adding and closing of sub-windows is best handled by the main-window. The CountryPage
class doesn't need to know anything about the sub-windows. The new/close buttons can be directly connected to methods of the main-window. This makes it easier to manage the sub-windows via the functions of the mdi-area.
Below is a re-write of your example which should do what you asked for:

with an Executor will cause your process to block until the jobs in the executor are completed; since they’re running infinite event loops, they will never complete and your Executor will never unblock.
Instead, just use the executor to kick off the jobs, and run your stuff afterwards. When you’re finally done, call .shutdown()

QUESTION
I was working in my project related to pyqt5 GUI. I used multiprocessing to make it faster. When I run my program in editor, it works fine. But when I converted my program into executable using pyinstaller, then while running the program through this executable, it's not working. GUI opens, but close once it comes to the multiprocessing portion of the code (I get to know this by putting some print statement)
I have also tried mutiprocessing.freeze_support()
, still it's not worked.
if I remove the multiprocessing, program through executable works fine, But I need to use multiprocessing to make it faster.
Any suggestion?
...ANSWER
Answered 2022-Jan-21 at 14:12I had the same problem a while ago, and I recommend using Nuitka hence it supports Multiprocessing. If the problem lasts, try to use the threading

QUESTION
I'm trying to scale a QPolygonF that is on a QGraphicsScene's QGraphicsView on its origin.
However, even after translating the polygon (poly_2) to its origin (using QPolygon.translate() and the center coordinates of the polygon received via boundingRect (x+width)/2 and (y+height)/2), the new polygon is still placed on the wrong location.
The blue polygon should be scaled according to the origin of poly_2 (please see the image below, black is the original polygon, blue polygon is the result of the code below, and the orange polygon is representing the intended outcome)
I thought that the issue might be that coordinates are from global and should be local, yet this does solve the issue unfortunately.
Here's the code:
...ANSWER
Answered 2022-Jan-20 at 00:25Before considering the problem of the translation, there is a more important aspect that has to be considered: if you want to create a transformation based on the center of a polygon, you must find that center. That point is called centroid, the geometric center of any polygon.
While there are simple formulas for all basic geometric shapes, finding the centroid of a (possibly irregular) polygon with an arbitrary number of vertices is a bit more complex.
Using the arithmetic mean of vertices is not a viable option, as even in a simple square you might have multiple points on a single side, which would move the computed "center" towards those points.
The formula can be found in the Wikipedia article linked above, while a valid python implementation is available in this answer.
I modified the formula of that answer in order to accept a sequence of QPoints, while improving readability and performance, but the concept remains the same:

Im trying to make a Pyqt5 app with aiohttp request, and asyncio tasks. Im using quamash package too and it requires Python 3.7 so i installed this version.(it didn't work on Python 3.10) The main reason i use asyncio and quamash is because i want to do requests and without freezing the GUI of the app.
I get this error when i click the Start button and close the app:

I fixed the error by installing previous release of aiohttp Orignally i had aiohttp 3.8.1.dist installed. I also knew it was working for me before on other version of aiohttp, so i looked up pypi.org/project/aiohttp/#history and turn out i had to uninstall aiohttp and install aiohttp==3.7.4.

QUESTION
I have a basic image viewer (mostly just trying to learn the quirks of QGraphicsView rather than labels) that I'm trying to allow some basic zoom and pan functionality. It loads a directory of images the user can click through, but fails to load the image. It will return the dimensions, but receives a float division by zero arrow when trying to set the scene. I have tried setting as a QImage, but it doesn't seem to make a difference.
actions_test.py
...ANSWER
Answered 2021-Nov-05 at 03:57The problem is you are constructing the ImageViewer with another QGraphicsView that you made in Qt Designer, "qgraphic_image", as its parent. This makes it a child widget inside of that parent graphics view, and it's effectively invisible as its viewport rect has no size (that is why you got a division by 0 error).
You can remove the "qgraphic_image" from your UI file, for now I just replaced it in the layout to try it:

Install PyQt5
You can use PyQt5 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
