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.
@@inesguardans1731 No problem at all. Here is what I referred: github.com/kenwaldek/pythonprogramming And This is my Note: github.com/Ron-Chang/MyNotebook/tree/master/Coding/0_System_Software/Sentdex/PyQt Most notes are took in English. If you need it I can translate the rest one later 😊 The most difference what I found in this tutorials is lots of widgets are parent to "PyQt5.QtWidgets" instead of "PyQt4.QtGui".
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.
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.
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...
The resource browser is for things like sounds and icons, resources that you use un the interface. It is common to have them organised in a sort of a library...
For those looking to find where qt designer is located if you are using Anaconda distribution, go to Anaconda folder and search "designer". You will see the qt designer.exe in the results.
With PyQt5, you have to do *pyuic5* or else it won't work. Took a while for me to figure that one out. Just make sure your Python/Scripts folder is in your PATH and should be good to go without specifying the whole path to pyuic5.exe
Please pin this comment. This was absolutely helpful for those using PyQt5, especially since it doesn't utilize a batch script like PyQt4, and the usage is a bit different (but can frustrate easily for some).
"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).
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 :-)
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!
I think I understand why 'sentdex' stopped at this point. Tha man isn't a masochist. Without bunches of trial and error, the QtDesigner is a real pain for anything other than really simple layouts. Even trying it for the simple text editor we were playing with had my teeth grinding and my eyes rolling. For more fun, try laying a border around a grid sometime. Anyone figured out how to make a thicker line using the Horizontal and Vertical Lines. Haven't played with the spacers yet to see if they are easier to muck about with. Also, I especially enjoy the fact that you cannot clearly see where the tool and status boxes are when starting with the MainWindow. Another note. When using the *(&^* layouts, especially the *(&^* grid layout.... its much easier to drop the various widgets on the screen in some sort of row/column layout and then drop the layout over them. I fact, I'm not sure there is any other way to create a grid layout in the QtDesigner. If anyone has experience with this, please chime in. ** For Windows users, if you want to avoid all that typing to execute the 'pyuic4.bat' converter program put the following into a batch file ('QtGen.bat' for instance): c:\python36\Lib\site-packages\PyQt4\pyuic4.bat -x %1.ui -o %1.py thus: 'QtGen myui' will take 'myui.ui' and create 'myui.py'. Remember to change the 'python36' to whatever the Python root directory is for the version you're using. Good luck everyone. Let's help each other out.
Very clear tuto and very pleasant. Thanks. As you mention, however, to bad there is no way to generate some logic associated to the objects in the ui. Like onclick button1, display panel 2, etc. Do you think xcode + Python would be a good solution ?
wtf man,, i became a pro in qt desinger after seeing your video for some 10 mins, previsouly i used place all objects here and there without knowing what i am doing and endup discarding and doing everything manually in code itself,, your tut was so easy to get into proper designing
Thanks for another great video. setting the PATH should make executing pyuic4.bat easier. ie: set PATH=%PATH%;full-path-to-directory-containing-pyuic.bat-here\ 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)
Hi everyone. Why is my "Layout in a Grid option" not showing when I right mouse click the main GUI that I am creating and 'right-mousing' and clicking on layout like what sentdex is doing at 3:41?
11:48 "Use connect to connect the functions to the buttons, but we've already covered how to do that" -- Sorry, covered where? It is not immediately obvious from the titles of other videos, and they are not numbered within a clearly marked series.
most likely this tutorial: pythonprogramming.net/basic-gui-pyqt-tutorial/ You can either follow the specific youtube playlists for the orders, or you can find the correct order on the website. Hope that helps your frustrations!
what you showed is quite easy.But I had the impression that this application you've shown can extract an executable file for each operating system separately!If I want to create an executable package the final version of the program how will I do it?
hello,As you have done executing the ui file adn saving the output in QtDesigner.py file when you are not able to view the code.But I can view the code in the qt dsigner.Then What should i do with it?do I need to copy the code and save it as some .py file??
Sentdex, I just watched your qtdesigner video and I’m concerned about making changes to the output code. If I decide to change the GUI afterwards I would have to renter all my connection code right? Seems cumbersome.
I followed your tutorail and tried to create a similar window, I also inserted some labels into that and now it is showing the following error: AttributeError: 'QLabel' object has no attribute 'setToolTipDuration' can you please help me in resolving this Thanks,
Hey, I have a really big question for you. How do you add toolbars and buttons to these buttons in Qt Designer? I am really frustrated! Thank you for the help!
Hi, 10:10 I get this error: '"C:\Python34\python"' is not recognized as an internal or external command, operable program or batch file. can you please help me with this?
I know this a month late, but did you make sure your file path was correct? Like there wasn't any unnecessary spaces or anything? And also, did you check to make sure Python34 was in the C:/ directory? I've used Python 2 and 3 and I've noticed that 2 installs automatically to the C:/ directory but 3 actually installs in your Program Files. (or your Program Files(x86), I forget which and it probably depends on whether you're running 32-bit or 64-bit). Lastly, check to make sure the designer is actually installed. Other than that, referencing the batch file should work, I've neglected adding my Python27 folder to the path in my command prompt, so I know that referencing the full path works to execute .exe and .bat files because I've used it to pip install a bunch of third party modules.
Ben O'Brien Okay. I don’t think Python is installed under c:/ directory. I managed to create my GUI with Tkinter, but I’ll try what you mentioned. Thanks
Thanks for sharing knowledge . i have question .I'm having last year project it has a part using Labview to draw a layout & control for pump and read somethings like RPM pressures and idk some reads from electronics PLC , and i have started learning basics of python as its free and found on internet that its good substitution for labview ,saw your video found that its easy with qt to draw better code . Can i use python or similar software to do these layouts and ctrl or not. if yes what should i start learning sorry if English was bad
Great tutorials! .I need to create a GUI with 3D cad capabilities: visualization and manipulation. As far as a I know, Tkinter is very limited in that regard. Do you have any recommendation on a module that I can use for my project?. Thanks
Hi buddy! I have created a simple design using this Qt designer containing buttons. Now i want that on click of button the python(2.7) Scripts should run (instead of running them from the command prompt). Also initially for my python Script to run it needs data which will be entered by user itself when the script runs. Now what should i do?? Please Help.
Could anyone suggest how dynamically use together python and the designer? I mean that based on the tutorial I could generate the pyqt code, but if later on I want to modify the layout, then the full code is regenerated and all previous callbacks are basically lost. Obviously I can always copy-paste to my old code the new layout, however I feel this is not the most professional solution. Thanks in advance. And thanks especially to sentdex for the great tutorials! :)
Daniel Campos Since then I find out that you can add the callback's to the GUI from another .py file. In this way your callback's code and the GUI layout is completely separated. I'm really new to python so my solution is definitely ugly but I can send to you in e-mail if you want.
thanks for good tutorial ...but i am facing some issue while doing this in ubuntu i m using qt4designer but after conversion it can not generate full python code like windows...please give some solution for this
[please help] I want to make a GUI program in python, in which the whole ui should update when I click a button!! is it possible in PyQT or should I go for Tkinter??
Make a link from /usr/bin/pyuic4 or pyuic5 to that folder and rename the link to uic. This will make it tons easier to copy/paste your code to your work directory.
Hi, thanks for the great content.I've got a question with my code.I tried Adding a back-ground stylesheet using qtdesigner but after turning my ui to a py file and imoprting the qrc file my app's UI seems gray and the background is not loaded.Also I get no errors.Everything runs smoothly exept for the background not shownig up.pls answer if you can I really need Help.thanks for your time.
thank you for these great tutorials, I have a problem using pyuic for changing ui to py code. I followed the instruction you said and I received the error: C:\Python27\Lib\site-packages\PyQt4\pyuic4.bat -x test1.ui -o test1.py Traceback (most recent call last): File "C:\Python27\Lib\site-packages\PyQt4\uic\pyuic.py", line 31, in from PyQt4 import QtCore ImportError: DLL load failed: %1 is not a valid Win32 application. I googled it but I couldn't find any proper solution, any idea what is the problem ?
I am using uic module to load ui file but it isn't showing any changes I make in that file in my py file. Can someone please tell me how can I make changes in my ui file and convert it to py file without losing changes in my previous py file?
+nazanin sh Nothing special there, say if your button is called bClick then add this line "self.bClick.clicked.connect(self.do_stuff)" in the setupUi function just after self.bClick is defined. Then define a function do_stuff and do your stuff there.
hey i tried your way but dont't know it's showing me same this command in cmd '"C:\Python34\python"' is not recognosed as an internam or external command, operable program or batch file.
Awesome video series. Do you have or can you make a video on how to use Qt Designer with PyQt5 (not 4) to create a GUI layout with python code in VS Code 2019 that opens a File Dialog Window (like windows 10) that can navigate file folders, select and open a text file and display in a GUI textbox?
sentdex PROBLEM 1 If the variable a contains a 1 and variable b contains a 2 write the shortest expression that evaluates to 0.5 using a,b but no literals or addition
First of All, Thanks for your efforts :) Please Is there a way to install Pyqt4 and Pyqt5 in my python? Note: I have already made all of the tutorial examples here using Pyqt5 and after using the qt5 designer, I reallly have a big issue in programming the functions of buttons :( I would be grateful if you can answer me...Thanks Again
Latest PyQt4 windows installer: sourceforge.net/projects/pyqt/files/PyQt4/PyQt-4.11.4/ If you install latest PyQt4 version for python 3.4 you can find QtDesigner in "path to your python 3.4 installation folder"\Lib\site-packages\PyQt4 Or you can find shortcut for Designer in: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\PyQt GPL v4.11.4 for Python v3.4 (x64)
Search pyqt5-tools, download the relevant wheel, extract files (using WinRAR or equivalent). designer.exe will be in one of the folders. When creating the python output, in my case, there was no batch file but rather an executable called pyuic5.exe in the "Scripts" folder of my environment. This generated an output file without issues.

And you still use the qtDesigner?
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.
Yep. These Python guys jump around in joy when they write 50 lines of code to successfully display a button on the screen.
Something like those Borland products and MS Visual Studio products have been doing via a drag and drop IDE in seconds since ancient history....

I mean that based on the tutorial I could generate the pyqt code, but if later on I want to modify the layout, then the full code is regenerated and all previous callbacks are basically lost. Obviously I can always copy-paste to my old code the new layout, however I feel this is not the most professional solution. Thanks in advance.
And thanks especially to sentdex for the great tutorials! :)
Did you figure out how? I'm also looking for a solution.
Daniel Campos Since then I find out that you can add the callback's to the GUI from another .py file. In this way your callback's code and the GUI layout is completely separated. I'm really new to python so my solution is definitely ugly but I can send to you in e-mail if you want.
Thank you very much for the answer. I would be very grateful if you could. daniel.campos.utfpr@gmail.com

I want to make a GUI program in python, in which the whole ui should update when I click a button!! is it possible in PyQT or should I go for Tkinter??
Fun Fact : That error still exists even after 4 years xD
Make a link from /usr/bin/pyuic4 or pyuic5 to that folder and rename the link to uic. This will make it tons easier to copy/paste your code to your work directory.
On windows anytime you want to run an exe or bat on cmd prompt all you need to do is add the bat file path to environment PATH. Is not an error.
Hi, thanks for the great content.I've got a question with my code.I tried Adding a back-ground stylesheet using qtdesigner but after turning my ui to a py file and imoprting the qrc file my app's UI seems gray and the background is not loaded.Also I get no errors.Everything runs smoothly exept for the background not shownig up.pls answer if you can I really need Help.thanks for your time.

thank you for these great tutorials,
I have a problem using pyuic for changing ui to py code. I followed the instruction you said and I received the error:
C:\Python27\Lib\site-packages\PyQt4\pyuic4.bat -x test1.ui -o test1.py
Traceback (most recent call last):
File "C:\Python27\Lib\site-packages\PyQt4\uic\pyuic.py", line 31, in
from PyQt4 import QtCore
ImportError: DLL load failed: %1 is not a valid Win32 application.
I googled it but I couldn't find any proper solution, any idea what is the problem ?
I am using uic module to load ui file but it isn't showing any changes I make in that file in my py file. Can someone please tell me how can I make changes in my ui file and convert it to py file without losing changes in my previous py file?
Can you please explain how to link a push button to the already existing python function.
+nazanin sh Nothing special there, say if your button is called bClick then add this line "self.bClick.clicked.connect(self.do_stuff)" in the setupUi function just after self.bClick is defined. Then define a function do_stuff and do your stuff there.
sir please make more video on Qt Designer !
what app you using to make it

Thanks for your video. How to download Qt designer using Pyqt4? thanks
Awesome video series. Do you have or can you make a video on how to use Qt Designer with PyQt5 (not 4) to create a GUI layout with python code in VS Code 2019 that opens a File Dialog Window (like windows 10) that can navigate file folders, select and open a text file and display in a GUI textbox?

PROBLEM 1
If the variable a contains a 1 and variable b contains a 2 write the shortest expression that evaluates to 0.5 using a,b but no literals or addition
+sentdex can you post a video on how to make a display window with this for pygame?
I was thinking of maybe a tileeditor example series?

Is there a way to install Pyqt4 and Pyqt5 in my python?
Note: I have already made all of the tutorial examples here using Pyqt5 and after using the qt5 designer, I reallly have a big issue in programming the functions of buttons :(
I would be grateful if you can answer me...Thanks Again
I installed PyQT5 on Windows but i dont see anywhere QT Designer. How do you install it?
search for pyqt5_tools-5.9.0.1.2-cp36-none-win32 or if you have amd get the other package
Latest PyQt4 windows installer:
sourceforge.net/projects/pyqt/files/PyQt4/PyQt-4.11.4/
If you install latest PyQt4 version for python 3.4 you can find QtDesigner in "path to your python 3.4 installation folder"\Lib\site-packages\PyQt4
Or you can find shortcut for Designer in:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\PyQt GPL v4.11.4 for Python v3.4 (x64)
"pip install pyqt5-tools"
No longer works.
Search pyqt5-tools, download the relevant wheel, extract files (using WinRAR or equivalent). designer.exe will be in one of the folders. When creating the python output, in my case, there was no batch file but rather an executable called pyuic5.exe in the "Scripts" folder of my environment. This generated an output file without issues.
