Checkbox Implementation in Python Using Qt Designer #shorts

Today we are going to learn how to use checkboxes in Python with Qt designer. Checkboxes are a great way to allow users to select multiple options in a user-friendly way. In this tutorial, we will cover how to create checkboxes in Qt designer, connect them to our Python code, and check their states.

Step 1: Setting up your environment
First, make sure you have PyQt5 installed on your system. You can install it using pip:

pip install PyQt5

Next, open Qt designer and create a new form. Drag and drop checkboxes from the widget box onto your form.

Step 2: Connecting checkboxes to Python code
Save your form as a .ui file and convert it to a .py file using the pyuic5 tool. This will generate a Python file with the necessary code to create your form in Python.

Next, create a new Python file and import the necessary modules:

from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5 import uic

Load your converted .py file and create a class that inherits from QMainWindow:

class MyForm(QMainWindow):
    def __init__(self):
        super().__init__()
        uic.loadUi('your_form_name.py', self)

Step 3: Check the state of checkboxes
Now, let’s add some functionality to check the state of our checkboxes. We will connect our checkboxes to a function that will print their states:

    def check_states(self):
        if self.checkbox1.isChecked():
            print("Checkbox 1 is checked")
        if self.checkbox2.isChecked():
            print("Checkbox 2 is checked")

Connect this function to a button click event:

self.check_button.clicked.connect(self.check_states)

Step 4: Running our application
Finally, create an instance of our MyForm class, show our form, and start the Qt event loop:

if __name__ == '__main__':
    app = QApplication([])
    form = MyForm()
    form.show()
    app.exec_()

Now you can run your Python script and see your checkboxes in action. Click on them to check their states, and press the check button to see which checkboxes are checked.

That’s it! You now have a basic understanding of how to use checkboxes in Python with Qt designer. Experiment with different functionalities and designs to create your own custom checkbox widgets. Enjoy coding!
