PyQt5 QCommandLinkButton - Checking Check State

PyQt5 QCommandLinkButton - Checking Check State

In PyQt5, the QCommandLinkButton does not have a check state by default, as it is essentially designed to be a button with a descriptive text, similar to a command link you might find in some Windows dialog boxes.

However, if you want to emulate a check state for a QCommandLinkButton, you would have to create a custom behavior by subclassing or using signals and slots.

One way is to change its text or icon based on a boolean value (to represent checked or unchecked). Here's a simple example:

import sys from PyQt5.QtWidgets import QApplication, QMainWindow, QCommandLinkButton, QVBoxLayout, QWidget class DemoApp(QMainWindow): def __init__(self): super().__init__() self.command_link_button = QCommandLinkButton("Unchecked", self) self.command_link_button.clicked.connect(self.toggle_check_state) self.checked = False # Our custom check state layout = QVBoxLayout() layout.addWidget(self.command_link_button) central_widget = QWidget() central_widget.setLayout(layout) self.setCentralWidget(central_widget) self.setWindowTitle('QCommandLinkButton Check State Example') self.show() def toggle_check_state(self): self.checked = not self.checked if self.checked: self.command_link_button.setText("Checked") else: self.command_link_button.setText("Unchecked") app = QApplication(sys.argv) window = DemoApp() sys.exit(app.exec_())

In the example above, when the QCommandLinkButton is clicked, its text changes to indicate a checked or unchecked state. This is a rudimentary way to emulate a check state. If you need a more comprehensive behavior, consider using QCheckBox or subclassing QCommandLinkButton to implement custom properties and methods.
