![]() ![]() If you run this code, you will note that the label does not appear correctly because the size is smaller than the font size we used. Self.ui.tFont(QtGui.QFont('SansSerif', 30)) # change font type and size To change the QLabel font, use the setFont() method and pass a QFont to it like this: from PyQt5 import QtWidgets, QtGui py file and let’s play with the label widget using code. Drag a label widget from the widget box on the left.Open PyQt5 designer and choose the Main Window template.To add a QLabel widget to your form, do the following: Now, let’s get our hands dirty and play with the PyQt5 widgets. ui file, and you need to be aware of your widgets names.Īnother benefit of using the second method is the speed since you don’t need XML parsing to load the UI. The benefit of using the second method is the auto-completion that the IDE will provide since all of your widgets are imported, while the first method you just load the. If you run this code, you should see the same window again as we did in the first method. from PyQt5 import QtWidgetsįrom mydesign import Ui_MainWindow # importing our generated file The pyuic5 stands for Python user interface converter version 5. Now, let’s import that file to show our window. Yes! That creates a new file with the name mydesign.py. ui file to a Python code: $ pyuic5 mydesign.ui -o mydesign.py Now, let’s try the second way by converting the. If you used app.exec() directly, the application would send zero, which means success, and this will happen even if the application crashed.Ĭonverting the. We used sys.exit(app.exec()) instead of using app.exec() directly to send the correct status code to the parent process or the calling process. That means the ui file loaded successfully! If you run your code, you should see a window with nothing but a label. Win = uic.loadUi("mydesign.ui") #specify the location of your. ui file in your Python code, you can use the loadUI() function from uic like this: from PyQt5 import QtWidgets, uic Now, to use this design, you have two ways: Then from the file menu, click save PyQt5 designer will export your form into an XML file with. Open PyQt5 designer, and choose Main Window template and click create button. In this tutorial, we will use the PyQt5 designer, but before we dig deeper, let’s see how we will use the generated design from the PyQt5 designer. It doesn’t have a built-in allowance for buttons like those in QDialog. QMainWindow is the bigger template where you can place your toolbar, menu bar, status bar, and other widgets.QDialog is used for asking the user about something, like asking the user to accept or reject something or maybe asking for input and is based on QWidget.QWidget is the base class for all GUI elements in the PyQt5.So we have three types of templates, what is the difference? Difference between QDialog, QMainWindow, and QWidget Widget: Creates a widget that is inherited from QWidget class, unlike the Dialogs templates which inherit from QDialog class.Main Window: Creates a window with a menu bar and a toolbar and inherited from QMainWindow.Dialog without Buttons: Creates a blank form.Dialog with Buttons Right: Creates a form with OK and Cancel buttons at the top right of the form.Dialog with Buttons Bottom: Creates a form with OK and Cancel buttons at the bottom right of the form.Open designer.exe, and you will see a dialog asking you about the form template you want. ![]() You can make a shortcut for it instead of going into this location every time you want to run the PyQt5 designer. $ pip3 install PyQt5-tools Where is PyQt5 designer?Īfter successful installation, you can find the PyQt5 designer on this location: C:\Program Files\Python36\Lib\site-packages\pyqt5-tools\Īlso, If you installed Python for your current user only, you will find the PyQt5 designer on this location: C:\Users\LikeGeeks\AppData\Local\Programs\Python\Python36-32\Lib\site-packages\ pyqt5-tools\ To install it, you need to install PyQt5 tools. In this PyQt5 tutorial, we will use the PyQt5 designer, which makes it so easy to finish a lot of work in a matter of seconds. There are two ways to build GUI apps using PyQt5: If no errors appeared, that means you have successfully installed PyQt5, but if you got errors, you might be using an unsupported version of Python. To ensure the successful installation, run the following Python code: import PyQt5 To install PyQt5 using pip, run the following command: $ pip3 install PyQt5 ![]() PyQt5 has two versions, the commercial version and the free GPL version that we will use in this tutorial. 13 Packaging Python files (Converting to executable) ![]()
