Qt Designer - PyQt with Python GUI Programming tutorial

The Qt Designer, which comes with PyQt, allows us to utilize a Graphical User Interface to help us make a graphical user interface!

We can use the Qt Designer to help with the user interface of our application, things like placement of buttons, layouts, and more can all be handled with the qt designer.

After 5 years, your "out dated" tutorial works even in Ubuntu 20.04 ! (Obviously had make so adjusts due to updated versions)
THANK YOU!

Im 21 and you re the best teacher i ever had...I ve learned soo much from you.Thanks!

[alexanderkarsonis]

Sentdex, wherever I look for Python tutorials you are there. Good job!

[maxime]

Thank you for this great tutorial series. I actually learned a lot, in so little time, thanks to your concise and meaningful explanations. Definitely a series I'll recommend.

Sentdex. I know it has been said many times but you are an absolute legend.

holy cow!! the way you presented the tutorial is amazing you left the designer to the end when one understands how pyqt works
reallyyyy amazingg

Thanks for keeping your content free, I still view all your content till this date . Thanks for sharing your knowledge <3

It took me two weeks to study and convert to PyQt5.
Especially, there's some issues on macOS.
But I did it! 🥳
Thank you, Harrison. You're amazing!👏

Anything i need for programming i just search your channel and find it!!!! Thanks for the great work

In around 2000 I dabbled with Borland's C++Builder, Delphi, J-Builder and they came with a fantastic GUI designer. Took minutes to do the layout and have ready made calls. Now I dabble with Python and notice... caveman stuff! Tkinter, guizero are ancient! Time to give this PyQt a tryout.

Thanks for these great video tutorials. I am trying to design an engineering tool by learning GUI development form your tutorials.

1. Could you please do one more video showing how to separate the user interface python files and python codes with actions corresponding to various buttons and menus in the UI file. The reason for this is when you use the Qt Designer and convert the .ui into .py file, it creates a new .py file whenever you make any changes to the .ui file. Keeping the action code in a separate file would be helpful. A basic housekeeping tutorial for such software development would be very helpful.

2. How to open another window by clicking a button on the main window

2. How to embed a VTK graphics window in a Qt5 GUI.

Will wait for more of your tutorials.

THIS VIDEO THOUGH, SAVED MY LIFE TODAY! THANK YOU!

Hi,

First off I love your videos! Thank you!

I am a teacher in the UK. The government here has scrapped my subject (ICT) and introduced compulsory Computer Science. It's fun and the theory is no problem but I am having massive issues linking the programming concepts together. I kind need to see something visualized to be able to piece it all together, as programming is something i am having to learn and learn quickly. As such, would you think it possible to do a video to show the following VERY program that (its no issue for me writing this in IDLE with no GUI btw)

1) Request the users name
2) Asks the user to add too random numbers (1-5)
3) Allows the user to answer
4) Repeat 5 times
5) Displays the number of questions asked
6) Displays the number correctly answered

I am really interested in making the interface functional.

I don't know if you can help, or indeed have the time to, but if you could I would be over the moon. Struggling to be honest.

Either way,

Thanks :-)

[luismora]

every time i need help you already got a vid for it, much thanks for all you do

[batteryjuice]

I would love to see more tutorials on Python Guis using the Qt. No matter if you make more or not though, thanks for theses videos; they really helped me.

[MatthewTaylorAu]

Thanks for another great video.

setting the PATH should make executing pyuic4.bat easier.
ie:
set

so the long dos prompt sample in the video becomes
pyuic.bat -x my_filename.ui -o my_filename.py


also: I needed to be in dos prompt as administrator (Windows 10)

10 years later, when people ask me how did I become the world's most famous app designer...


I would say it started here.

[technolus]

"pyuic4" instead of "pyuic" is more like it. Plus if it is still not recognized, just add "C:\tools\python" to "PATH" in the environment variables.

Notes:
-see if folder exists first, if doesn't exist look for a similar one with perhaps a version number attached to it
-in the environment variables (accessible through properties on this computer folder>advanced>environment variables>path>add).

I'm 23 and I remember that when I started programming in Python even the easiest UI could be a challenge... it makes me feel old when I see how open source software have been developed since then...

[daineXx]

I must say youre videos have really helped me advancing with python and its many libraries!
Thank you so much and keep up the good work!
I would be so happy if you did more 3d game programming also, i really liked the OpenGL stuff!
