PyQt5 QScrollBar - Getting Inverted Control Property

PyQt5 QScrollBar - Getting Inverted Control Property

In PyQt5, the QScrollBar widget provides a scroll bar with which the user can interact. The invertedControls property determines whether the scroll bar controls are inverted or not.

When invertedControls is True, right-clicking on the scroll bar will decrement its value, and left-clicking will increment it. This is opposite to the default behavior, where left-clicking decrements the value and right-clicking increments it.

To get the invertedControls property of a QScrollBar, you can use the invertedControls() method.

Here's an example demonstrating this:

import sys from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QScrollBar, QLabel class App(QWidget): def __init__(self): super().__init__() self.initUI() def initUI(self): layout = QVBoxLayout() # Create a QScrollBar scrollbar = QScrollBar(self) layout.addWidget(scrollbar) # Check the invertedControls property if scrollbar.invertedControls(): text = "The QScrollBar controls are inverted." else: text = "The QScrollBar controls are not inverted." # Display the result label = QLabel(text, self) layout.addWidget(label) self.setLayout(layout) self.setWindowTitle('QScrollBar Inverted Control Property') self.show() if __name__ == '__main__': app = QApplication(sys.argv) ex = App() sys.exit(app.exec_())

In the example above, we created a QScrollBar and then checked its invertedControls property. The result is displayed in a QLabel. By default, the invertedControls property is False, so the program will indicate that the controls are not inverted.
