Working With Qt Designer’s UI Files And PyQt

Qt Designer is a powerful tool for creating user interfaces for your PyQt applications. It provides a graphical interface for designing and laying out your UI components, making it easy to create professional-looking interfaces with minimal effort.

One of the key features of Qt Designer is its ability to generate UI files, which are XML-based files that describe the layout and components of your user interface. These UI files can then be loaded and used in your PyQt application, making it easy to visually design your UI components and then use them in your code.

To work with UI files in your PyQt application, first, create your UI design in Qt Designer and save the UI file. Then, you can load the UI file in your Python code using the uic module from PyQt.

Here’s an example of how to load a UI file and use it to create a PyQt application:

		import sys
		from PyQt5 import QtWidgets, uic

		# Load the UI file
		form = uic.loadUi("my_ui_file.ui")

		# Create a PyQt application using the loaded UI file
		app = QtWidgets.QApplication(sys.argv)
		form.show()
		sys.exit(app.exec_())
	

Once the UI file is loaded, you can access and manipulate the UI components just like any other PyQt widget. This allows you to easily integrate your UI design with your application logic and create a fully functional PyQt application.

Working with Qt Designer’s UI files and PyQt can greatly simplify the process of creating user interfaces for your applications. By visually designing your UI components and then using them in your code, you can create professional-looking interfaces with minimal effort.

Whether you’re a beginner or an experienced developer, Qt Designer and PyQt provide a powerful combination for creating modern and responsive user interfaces.

Qt designer is not free

I like to name like this: (assuming a button) btn_button_name.

That way if I forget what the button is called it's very easy to bring up the autocomplete and see a list of every button just by typing "btn". I find it much easier to remember the type of control I'm looking for instead of the name and once I narrow down the lists to types it's usually pretty obvious which specific buttons (or other types) I'm looking for.

1st Class tutorial. Nicely done Derek! Qt & I go back well over 15 years (C++ & Qt Creator), and pyQt maybe 8 years give or take… it just never gets old!

You don't need to connect the signal and the slot, if you name your function "on_<object>_<signal>" in this case "on_one_btn_clicked" qt connect them automatically, this is nice because enforces consistency among multiple programmers and avoid bloat on the code.

I'm trying to dig into python and qt because I want to write an application. So, to sum it up… this method is preferred because:
1) you don't generate a bloated ui file
2) you can make changes on the fly without having to rebuild the ui file

is that correct? so, does the method DT showed in the previous video has its advantages?

Btw, thanks as always for your videos DT, you're the best!

just rename your buttons the other way. btn_one … With intellisense when you hit bt all your buttons are grouped together to choose the one you want.

If you want a python script to run in headless mode (w/o console output) you can change the extension to .pyw instead of .py. Obvs your xmonad hides that stuff anyway but might be good for hiding your script's console output from your users.

12:14 if you are feeding script to python executable like that, chmod +x does nothing in that case

Why not using PySide which is an official Qt project and probably has more maintainers? The interface and syntax is similar and even more pythonic.
Loading ui files directly is easier. Only disadvantage is not having a py file for type hints and annotations. But do vim users even know what they're missing 😀

qt designer and PyQt are great; but I don't really like using pyuic and prefer to import .ui files at runtime. Indeed, it gives a better separation between the UI and the code and is simpler to maintain over time. Of course, this is only usefull if we use Qt Designer.. Direct coding the ui in PyQt is also a option but I usually find it frustrating…
