PyQt5 - How to check visibility status of label?

In PyQt5, checking the visibility status of a QLabel (or any QWidget) can be done using the isVisible() method. This method returns a boolean value: True if the widget is visible and False if it's not.

Here's a simple example to demonstrate how you can check the visibility status of a QLabel:

1. Import PyQt5 Modules

First, import the necessary PyQt5 modules:

from PyQt5.QtWidgets import QApplication, QWidget, QLabel, QVBoxLayout, QPushButton import sys

2. Create a Function to Check Visibility

Define a function that checks the visibility of the label:

def check_label_visibility(): if label.isVisible(): print("Label is visible") else: print("Label is not visible")

3. Create the Main Application and Widgets

Set up the main application, create a label, a button to toggle the label's visibility, and another button to check the label's visibility:

app = QApplication(sys.argv) window = QWidget() # Create a label label = QLabel("This is a label") # Create a button to toggle visibility toggle_button = QPushButton("Toggle Label Visibility") toggle_button.clicked.connect(lambda: label.setVisible(not label.isVisible())) # Create a button to check visibility check_button = QPushButton("Check Label Visibility") check_button.clicked.connect(check_label_visibility) # Layout layout = QVBoxLayout() layout.addWidget(label) layout.addWidget(toggle_button) layout.addWidget(check_button) window.setLayout(layout)

4. Show the Window

Display the main window:

window.show() sys.exit(app.exec_())

Complete Example

Here's the complete example put together:

from PyQt5.QtWidgets import QApplication, QWidget, QLabel, QVBoxLayout, QPushButton import sys def check_label_visibility(): if label.isVisible(): print("Label is visible") else: print("Label is not visible") app = QApplication(sys.argv) window = QWidget() label = QLabel("This is a label") toggle_button = QPushButton("Toggle Label Visibility") toggle_button.clicked.connect(lambda: label.setVisible(not label.isVisible())) check_button = QPushButton("Check Label Visibility") check_button.clicked.connect(check_label_visibility) layout = QVBoxLayout() layout.addWidget(label) layout.addWidget(toggle_button) layout.addWidget(check_button) window.setLayout(layout) window.show() sys.exit(app.exec_())

When you run this script, you will see a window with a label and two buttons. The "Toggle Label Visibility" button will show or hide the label, and the "Check Label Visibility" button will print the label's visibility status to the console.
