Custom Widgets in PyQt and PySide: Floating and Absolute Positioned Widget, Menu, and Container in QT

In PyQt and PySide, you can create custom widgets/layouts that have floating/absolute positioning using the QWidget class. This allows you to create more dynamic and interactive UIs for your applications. In this tutorial, we will walk through the steps to create a floating/absolute positioned widget/menu/container in PyQt.

Step 1: Import the necessary modules
First, you need to import the necessary modules for PyQt or PySide. You can do this by adding the following lines of code to your script:

from PyQt5 import QtWidgets, QtCore

Step 2: Create the main window
Next, you need to create the main window for your application. You can do this by adding the following code:

app = QtWidgets.QApplication([])
main_window = QtWidgets.QMainWindow()
main_window.setGeometry(100, 100, 800, 600)
main_window.setWindowTitle("Floating Widget Tutorial")

Step 3: Create the floating/absolute positioned widget
Now, we can create the floating/absolute positioned widget. This widget will be a custom widget that will be positioned at a fixed location on the screen. You can do this by creating a custom class that inherits from QtWidgets.QWidget and setting its position using the move method. Here’s an example:

class FloatingWidget(QtWidgets.QWidget):
    def __init__(self):
        super().__init__()
        self.setGeometry(200, 200, 200, 200)
        self.setWindowTitle("Floating Widget")
        self.move(300, 300)

Step 4: Display the floating widget
Now that we have created the floating widget, we can display it on the main window. You can do this by creating an instance of the FloatingWidget class and calling the show method. Here’s an example:

floating_widget = FloatingWidget()
floating_widget.show()

Step 5: Run the application
Finally, you need to run the application by calling the exec method on the QApplication instance. Here’s how you can do this:

app.exec_()

That’s it! You have successfully created a floating/absolute positioned widget in PyQt. You can customize the widget further by adding additional features, such as buttons, labels, or input fields. This allows you to create more interactive UIs for your applications.
