PyQt5 - Access the size of the Label

In PyQt5, you can access the size of a QLabel using the size() method, which returns a QSize object. This object holds the width and height of the widget. To get the width and height separately, you can use the width() and height() methods of the QSize object.

Here's a simple example of how to access the size of a QLabel in PyQt5:

import sys from PyQt5.QtWidgets import QApplication, QLabel, QWidget, QVBoxLayout app = QApplication(sys.argv) # Create a main window widget window = QWidget() # Create a label with some text label = QLabel('Hello, PyQt5!', window) # Set the size of the label label.resize(200, 50) # Print the size of the label print("Label size:", label.size()) # QSize object print("Label width:", label.width()) # Width of the label print("Label height:", label.height()) # Height of the label # Use a layout to manage the widgets' geometry layout = QVBoxLayout(window) layout.addWidget(label) # Show the main window window.show() # Execute the application sys.exit(app.exec_())

In this code:

  • A QLabel is created with some text.
  • label.size() returns the QSize object from which the width and height can be accessed.
  • label.width() and label.height() return the width and height of the QLabel, respectively.

When the QLabel is displayed within the window, you can see its size printed in the console.

Remember to replace 'Hello, PyQt5!' with the actual text you want to display and adjust the size accordingly if needed. The resize method is used to set the label size explicitly in this example, but in a typical application, layout managers would often handle the sizing.
