PyQt5 - isLeftToRight() method for Check Box

In PyQt5, the isLeftToRight() method is available for many widgets, including QCheckBox. This method is inherited from the base QWidget class. It checks whether the layout direction for the widget (or for the application as a whole if not set for the widget specifically) is left-to-right (common for languages like English) or right-to-left (common for languages like Arabic or Hebrew).

Here's how you can use isLeftToRight() with a QCheckBox:

import sys from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QCheckBox class Example(QWidget): def __init__(self): super().__init__() self.initUI() def initUI(self): layout = QVBoxLayout() # Create a checkbox checkbox = QCheckBox('Check me!', self) layout.addWidget(checkbox) # Check the layout direction if checkbox.isLeftToRight(): print("The layout direction is left-to-right.") else: print("The layout direction is right-to-left.") self.setLayout(layout) self.setWindowTitle('isLeftToRight Example') self.show() app = QApplication(sys.argv) ex = Example() sys.exit(app.exec_())

When you run this code, the program will create a window with a checkbox and print the layout direction to the console.

If you want to change the layout direction to right-to-left, you can set it using setLayoutDirection(). For example:

checkbox.setLayoutDirection(Qt.RightToLeft)

After setting this, isLeftToRight() will return False.
