[@alandmoorecodes3585]

This is one of those mistakes I ran into far too often and just had to make a video, because explaining it again and again on reddit or other forums was too tedious. To be fair, a lot of people just aren't thinking they're going to go back and re-edit the layout in Designer, they just want to get something going. Unfortunately the demo code that pyuic5 tacks onto the bottom steers them in the wrong direction about how to actually use the class.

[@isidrodeleon673]

Excellent video. I add that the UI compiler can be configured in the IDE (in my case I use PyCharm) as an "external tool", so that, after modifying and saving the .ui file with QtDesigner, it is no longer necessary to manually compile the file .ui (with just three clicks inside PyCharm, and the updated code appears).

[@MrMrDbjock]

Thank you for teaching the sanity, and correct "python" way. I have been watching many vids and they either change the generated code which I know is wrong since all those changes would have to be done again, or the import the ui, which makes the app way slower at start up. I was struggling getting my mind wrapped around using these classes and you made it clear :-). Your book is now on it's way to my home. Thank you again for the clarity.

[@alandmoorecodes3585]

Glad I can help!

[@KeeganDent]

My bigger problem with loading the ui dynamically with PyQt5.uic is that your editor cannot give you any context-aware code completion, and you instead have to keep Qt Designer open and read it like a blueprint, also going to the Qt documentation every time you forget the name of a relevant method. Just a terrible workflow when you could instead have a static file for your editor to provide clues on.

I'm an artist and I always liked to learn programming languages... a few years ago I started learning Python by myself, searching tutorials here and there, when I knew about QT Designer I said to myself: "This is what I need, I'm an artist, I need visual design". Then, a few days later I understand is much more easy and fun (to me) code the full UI, it's make easy to me to add a "UI presets menu" to the app I was doing that let the user change the app apareance. Thanks for the video, is amazing

[@Scion141]

Lol. Maybe it's because I'm NOT an artist, and I've been doing all manner of coding in the past 10 years. But I'm over coding my UI elements, especially when there's a better alternative, like using a designer program and dragging and dropping the elements that I need.

[@miguelangelrivas8692]

[@leej350]

It was interesting watching this video, because I’m reading your book (well, re-reading. Qt is complicated). On your ending comments about coding directly instead of using Designer: I do know from your book how you quickly create some sets of widgets (some of it’s not really ‘manual’, wink-wink.). But also, I’ve created a few more involved GUIs, and I can appreciate making some big changes in Designer, then quickly back up in running editing the slots and other methods without having to worry about the GUI code. So I’ll probably keep doing it both ways. Thanks for your book. Cheers. :-)

[@Inksaver]

As a C# developer and only recently discovered PyQt5, I am familiar with working with multiple files, and the idea you do NOT mess with MainForm.Designer.cs directly. I have been following a YT course using the designer, and doing exactly what you should not do, which worked well, but was frustrating if you need to re-design anything, so your video was an excellent introduction to the correct way to use it. I disagree with your views on using it in the first place, as I find beginners like to see instant results, especially when using CSS in the StyleSheet property. They can check their design and adjust it to perfection, which encourages them to tackle the code needed to interact with their shiny new GUI. Using PyQt designer is similar to using WPF in C#, where you can hand-code directly in XAML, or use the built-in WPF designer in Visual Studio. Book ordered from Amazon uk!

Hi, thanks for the tutorial. I am a beginner in python and I did it exactly the wrong way you've shown. Now I am modifying my code and do it the right way by having separate files main program and ui. However, i am still confused about the signal and slot method. For example I have a push button that is disabled initially but will be enabled once there is a textedit in a line edit. It seems to me that it should be done in the ui file instead of the main file. But I couldnt find the right signal and slot to connection to do this so I end up writing this connection in the main file. Any idea which one should be inside the ui and which one in the main?

[@jiakai7254]

for those trying to override code in Ui_MainWindow, u need to inherit it as well to have access to its objects.

[@alialsoumahi4207]

It is really great advice but it has one drawback which is you need to recompile the QT designer code for every time you change on it to get the module and then included in main python file as described above on youtube vedio. My question is why we don't link the XML of the QT designer withen the python code and read that XML file automatically so once the QT designer changed, it will change as well in python code so no need for recompiling and get the python code of QT designer. My idea is actually taken from Java FXML. In Java FXML once we change in the scene builder automatically reflect on the XML which java will read and new change will be available for you to make custom functions to deal with your new change.t

[@tedtoad2471]

Hello, great video! So I'm starting to work my way through the book. I'm using Visual Studio Code, did a pip install of PyQt5 ran the first couple of demos and all was good. Installed Designer and messed with it a bit then went back to my saved code in VSC and now get the error ImportError: DLL load failed while importing QtWidgets: The specified module could not be found. No matter what I do. Windows install, Python 3.8. Thanks. EDIT: Uninstalled PyQt5 and reinstalled and now it works. Seems Designer overwrote something PyQt5 needed.

[@markustaugwalder8582]

Hi, great video! I wonder what is the difference to using uic and load the ui file with that when running the app in terms of inheritance, using the widgets from within the View class that inherits the Ui_Form, using them from an outside Model class and finally what about the signals? Do you recommend using uic or is it better the way you show us? I'm sorry for all these "heavy" questions. So far I couldn't find good answers for these, I only found bad examples.

[@markustaugwalder8582]

I went through your videos and most helpful is this one: kzbin.info/www/bejne/a4LTmKiXg6uYmbM

[@alandmoorecodes3585]

Thanks Markus; keeping in mind that I'm not a huge fan of using QtDesigner, so I haven't worked out the best ways to make use of .ui files, I find that loading .ui files at runtime is a little awkward since it requires having a QApplication instantiated first. But maybe there's an elegant solution to that. Normally I just hand code the GUIs.

[@angel_machariel]

I come from C#/C++. Surely there's some Model-View design pattern for this. Edit: and this is a very good video telling how it is. If one would argue that GUI's are made in RAD's these days, then they forgot about the endless number of programmers who still use XAML to make GUI's in Visual Studio for example.

[@calinapascu5241]

Hi! What if you have multiple windows that have to open? For exemple, if a pushbutton in pressed in the main window, then a second window shows up. I'd have both windows generated with qt designer. How do you write the code for main ?

[@calinapascu5241]

Should I create different classes inside main.py ? But how do I show the second window and pass the variables ?

[@alandmoorecodes3585]

you would create a different subclass of QWidget for each window. Your callback in the first window would then create an instance of the second class and call it's .show() method. There is an example of one window opening another in my book, you can see the code here: github.com/PacktPublishing/Mastering-GUI-Programming-with-Python/blob/master/Chapter03/form_window.py It does not use QtDesigner, but the principle applies either way. The only difference is that each QWidget class's __init__ method would create the applicable UI class rather than manually building the widgets.

[@AnilKumar-hr8yl]

Thank you it was really very well informed. How can we extend this code for multiple windows?

[@alandmoorecodes3585]

You'll just repeat the process for each window. Probably only the main application should be based on QMainWindow, the others should be QWidget-based. The thing to understand is that the code you get from designer is *not* your window/widget class, it's a ui builder that is meant to operate on a window/widget class which you provide.

[@haleyharrison5653]

Hello, I'm really glad I found your channel. It is the only one so far that actually has academic roots and I appreciate that. Do you have any code that uses pandas and PyQt5 together? I am trying to display some data from a database. Depending on the data my users choose, that data could look very different but with the same column names. I am trying to add check boxes inside the qtablewidget so users dont have to type the names of the rows they want to keep (additional processes are made with those names they choose later on). Here is what I have for putting the data into the qtablewidget. Is there an easier way? def update_table(self, df_name): self.ui.dataframe.setRowCount(0) self.ui.dataframe.setColumnCount(0) self.ui.dataframe.setRowCount(len(df_name)) self.ui.dataframe.setColumnCount(len(df_name.columns)) self.ui.dataframe.setHorizontalHeaderLabels( list(df_name.columns)) i = 0 while i < len(df_name): for col in df_name.columns: self.ui.dataframe.setItem( i, (df_name.columns.get_loc(col)), qtw.QTableWidgetItem( str( df_name[col].iloc[i] ) ) ) i += 1 And for the checkboxes inside the qtablewidget, is that possible/practical? The users basically just want to check something instead of type it in. Thank you in advance.

[@alandmoorecodes3585]

It's possible to put something other than a text widget in a tablewidget cell, but it breaks a lot of the automatic model/view behavior and you'll need to do a lot of custom code around it. I haven't done work with combining Pandas and Qt, but depending on how complex your application is going to be you might be better off building a model around your Pandas data. Then your GUI doesn't have to be so intimately tied to Pandas, the model can handle all that.

[@haleyharrison5653]

Thank you for the advice. I will research that a little more to see what I would need. I would be very interested in hearing/learning more about about the model-based views and how they are different from the widget based items in PyQt5. Thanks again!

[@codenio]

One more point, we could use "loadUiType" function under "PyQt5.uic" package to load ui files directly into Main Window, which avoid conversion for .ui files into .py files # example code from PyQt5.uic import loadUiType Ui_MainWindow, QMainWindow = loadUiType('login_form.ui') class MainWindow(QMainWindow, Ui_MainWindow): def __init__(self, *args, **kwargs): super(MainWindow, self).__init__(*args, **kwargs) self.setupUi(self)

Hi Alan, It was very nice video. I am using your way. First design in QT designer, then use pyuic5 then create a second file to call the converted file and prevent to overwrite on pyuic5's file. But I have 1 problem which is making me crazy. Firstly, in the second file we use super().__init() to initialize. But if the class inherit from 2 other classes, one is pyuic5's file and the other class, how we can use __init__??? For the second class, for example call it ClassB, we can use ClassB.__init__(*arg), but what we should use for pyuic5??? If i dont use super().__init__() i will face with error, while if I use super().__init__ I can initialize ClassB :(((( So how we can solve the problem of parallel inheritances when one of them is related to pyqt?? .

[@alandmoorecodes3585]

In theory, you save some initial start-up compilation time, but I doubt this is significant in most cases. In all honesty, I'm not a fan of using QtDesigner at all, so I may be speaking from a place of ignorance, but I find the process of rendering .ui files in a script to be somewhat awkward. I find it simpler to just import a Python file if I'm going to go with the QtDesigner route at all.

Thanks for your ideas. At the moment I can't do much with the Pi since my daughter has appropriated it for her own use; got a Pi 4 on the Christmas wish list, maybe I can do a new video if it shows up in my stocking. :-) In general, though, doing pretty much anything with a Pi and PyQt5 is going to run along the same lines as what was done in the book: create a QObject subclass to manage the GPIO interactions, use signals and slots to communicate back to the GUI, and use QThread to keep the GUI from locking up. The sensor example in the book could be adapted to any GPIO operations you want to run, really.

I'm sure I'm doing this wrong, but I did this but instead of QWidget I did it with QMainWindow. It essentially rendered multithreading useless. Now the GUI freezes whenever I do any long running processes, not an issue when I did it "the wrong way". I created a very large project "the wrong way" and was able to manage it with diffing code whenever I needed to go back and add some designer element (which I know is wrong and bad because it is difficult to manage). BUT I did not have issues with threads blocking the main window. Can you do another video like this but instead of QWidget, show how QMainWindow is supposed to be?

Hey Alan, I've got 2 questions. 1. It's Is it possible to create window or internet browser like transition in pyqt5? At present, we are using Qdialog to display the new window each time we click a button. 2. What is the best way to display images on our window? I and my friend are working on a project (DBMS with pyqt5) we have a lot character images to display.

[@alandmoorecodes3585]

You can do some things using QPropertyAnimation, but it's somewhat tedious and limited; it only works on Qt Properties, which many things you'd like to animate are not (colors, for instance). To make it work for those things, you have to implement them as properties in a subclass. QML might be a better approach if you want something really animated with fancy transitions. The simplest way to display an image is to put it in a QPixmap and display it with a label. Nothing wrong with that approach, but if you want to do fancier things or layer a lot of images (for a 2D game, for instance), you might look into a QGraphicsScene, which is Qt's answer to the Canvas objects you find in HTML/Tkinter/etc.

I recommend seeking some other more reliable source of information on this topic to avoid a lot of trouble and confusion.
