PyQt5 QCommandLinkButton - Released Signal

The QCommandLinkButton is a PyQt5 class that provides a command link button with a text label, an optional icon, and a large description area. This class is useful when you want to present an action or a command in a more descriptive and visually appealing way.

One of the important features of the QCommandLinkButton is the released signal. This signal is emitted when the button is released, either by clicking on it or by using keyboard navigation.

To use the released signal, you need to create an instance of the QCommandLinkButton class and connect it to a slot, which is a method that will be called when the signal is emitted.

Here's an example of how to use the released signal in PyQt5:

from PyQt5.QtWidgets import QApplication, QDialog, QCommandLinkButton, QVBoxLayout

class MyDialog(QDialog):
    def __init__(self):
        super().__init__()
        
        self.setWindowTitle("QCommandLinkButton Example")

        layout = QVBoxLayout()

        button = QCommandLinkButton("Click me")
        button.released.connect(self.on_button_released)
        layout.addWidget(button)

        self.setLayout(layout)

    def on_button_released(self):
        print("Button released")

if __name__ == '__main__':
    app = QApplication([])
    dialog = MyDialog()
    dialog.show()
    app.exec_()

In the above example, we create a custom dialog that contains a single QCommandLinkButton. We connect the released signal of the button to the on_button_released method, which simply prints "Button released" when the signal is emitted.

You can replace the print statement with any action or code that you want to execute when the button is released. This allows you to perform custom operations based on the user interaction with the button.

That's how you can use the released signal of the QCommandLinkButton class in PyQt5. It provides an intuitive way to handle button releases and makes your GUI application more interactive and user-friendly.
