Creating a Modern Flat GUI for a Python Desktop App with Splash Screen using QT Designer, Pyqt, and Pyside

In this tutorial, we will be creating a Python desktop application with a splash screen using QT Designer, PyQt or PySide, and a modern flat GUI design. Splash screens are a great way to give users a preview of your application while it loads its components in the background.

To start, you will need to have Python installed on your system along with PyQt or PySide. If you don’t have PyQt or PySide installed, you can install them using pip:

pip install PyQt5

or

pip install PySide2

Then, you will also need QT Designer, which is a GUI design tool for creating Qt-based applications. You can download QT Designer from the official Qt website or install it using pip:

pip install pyqt-tools

Once you have everything installed, we can start creating our Python desktop application with a splash screen.

Step 1: Designing the Splash Screen in QT Designer
Open QT Designer and create a new dialog-based GUI application. Design your splash screen by adding labels, images, and any other elements you want to display. You can customize the layout, colors, and fonts to your liking to create a modern flat GUI design.

Step 2: Converting the .ui file to Python code
Save your design as a .ui file. To convert the .ui file to Python code, you can use the pyuic tool that comes with PyQt or PySide. Run the following command in the terminal:

pyuic5 -x splash_screen.ui -o splash_screen.py

Step 3: Adding functionality to the splash screen
Now that we have our splash screen design converted to Python code, we can start adding functionality to it. In the main application file, import the generated splash screen code and create a new class that inherits from QMainWindow:

from PyQt5.QtWidgets import QMainWindow
from splash_screen import Ui_SplashScreen

class SplashScreen(QMainWindow, Ui_SplashScreen):
    def __init__(self):
        super().__init__()
        self.setupUi(self)

        # Add any additional functionality here

Step 4: Running the splash screen
In your main script, create an instance of the SplashScreen class and show it using the show() method. You can also set a timer to close the splash screen after a certain amount of time:

import sys
from PyQt5.QtWidgets import QApplication
from splash_screen import SplashScreen

app = QApplication(sys.argv)
splash_screen = SplashScreen()
splash_screen.show()

# Close the splash screen after 3 seconds
QtCore.QTimer.singleShot(3000, splash_screen.close)
sys.exit(app.exec_())

And that’s it! You now have a Python desktop application with a splash screen using QT Designer, PyQt or PySide, and a modern flat GUI design. You can further customize and expand your application by adding more features and functionality to it.

I hope this tutorial was helpful in guiding you through creating a splash screen for your Python desktop application. Let me know if you have any questions or need further assistance. Happy coding!
