PyQt5 QCalendarWidget - Icon Changed Signal

PyQt5 QCalendarWidget - Icon Changed Signal

In PyQt5, the QCalendarWidget does not have a built-in signal to indicate when its icon changes because it doesn't inherently deal with icons in the manner that, for example, a QPushButton might.

However, if you're customizing the QCalendarWidget in a way that involves icons or if you have a specific use-case involving icons, you might have to implement a custom solution.

Here's a simple example demonstrating how you might handle an "icon changed" signal using a custom subclass:

import sys from PyQt5.QtWidgets import QApplication, QMainWindow, QCalendarWidget, QVBoxLayout, QWidget from PyQt5.QtCore import pyqtSignal class CustomCalendar(QCalendarWidget): # Define a new signal iconChanged = pyqtSignal() def setIcon(self, icon): # Custom method to set icon (as an example) # ... [Code to set icon] # Emit the signal once the icon changes self.iconChanged.emit() class AppDemo(QMainWindow): def __init__(self): super().__init__() self.resize(400, 400) container = QWidget() layout = QVBoxLayout() self.calendar = CustomCalendar() # Connect to the custom signal self.calendar.iconChanged.connect(self.onIconChanged) layout.addWidget(self.calendar) container.setLayout(layout) self.setCentralWidget(container) def onIconChanged(self): # Slot to handle icon change print("Icon changed!") app = QApplication(sys.argv) demo = AppDemo() demo.show() sys.exit(app.exec_())

In this example, a CustomCalendar class inherits from QCalendarWidget. We define a custom signal iconChanged and a method setIcon(). Whenever you call setIcon(), the iconChanged signal is emitted.

You can then connect to this signal in your main application or UI code and handle the icon change as needed.

Remember, this is a basic example, and the real implementation might need adjustments based on where and how you are actually managing icons with the QCalendarWidget.
