PyQt5 QDockWidget - Getting Layout Direction

In PyQt5, the QDockWidget class provides a widget that can be docked inside a QMainWindow or floated as a top-level window. If you want to get the layout direction (left-to-right or right-to-left) of a QDockWidget, you can use the layoutDirection() method.

Here's how you can do it:

  1. First, make sure you have PyQt5 installed:

    pip install pyqt5

  2. Use the following sample code to create a QDockWidget and get its layout direction:

import sys from PyQt5.QtWidgets import QApplication, QMainWindow, QDockWidget, QTextEdit from PyQt5.QtCore import Qt class MainWindow(QMainWindow): def __init__(self): super().__init__() # Create a QTextEdit widget self.text_edit = QTextEdit(self) self.setCentralWidget(self.text_edit) # Create a QDockWidget self.dock = QDockWidget("Dock", self) self.addDockWidget(Qt.LeftDockWidgetArea, self.dock) # Check layout direction of QDockWidget layout_direction = self.dock.layoutDirection() if layout_direction == Qt.LeftToRight: print("Layout direction is left-to-right.") elif layout_direction == Qt.RightToLeft: print("Layout direction is right-to-left.") self.setGeometry(100, 100, 600, 400) if __name__ == "__main__": app = QApplication(sys.argv) window = MainWindow() window.show() sys.exit(app.exec_())

When you run this code, it will display a main window with a docked widget on the left side and print the layout direction of the QDockWidget to the console.

Remember, the default layout direction will typically be left-to-right unless you explicitly change it or your system's default layout direction is right-to-left (as in some languages like Arabic or Hebrew). You can set the layout direction using the setLayoutDirection() method.
