[FIXED] Qt module alternative for PyQt6

Issue

I'm just migrating my application from PyQt5 to PyQt6. I understand that the Qt module has been removed in Qt6. I have stuff like 'Qt.AlignCenter', 'Qt.ToolButtonTextUnderIcon', 'Qt.LeftToolBarArea', which are no longer working. Is there any alternative for this functionality in Qt6?

Solution

The Qt module only exists in PyQt5 (not in Qt5) that allowed access to any class or element of any submodule, for example:

$ python
>>> from PyQt5 import Qt
>>> from PyQt5 import QtWidgets
>>> assert Qt.QWidget == QtWidgets.QWidget

That module is different from the Qt namespace that belongs to the QtCore module, so if you want to access Qt.AlignCenter then you must import Qt from QtCore:

import sys
from PyQt6.QtCore import Qt
from PyQt6.QtWidgets import QApplication, QLabel


def main():
    app = QApplication(sys.argv)
    w = QLabel()
    w.resize(640, 498)

    w.setAlignment(Qt.Alignment.AlignCenter)
    w.setText("Qt is awesome!!!")
    w.show()

    app.exec()


if __name__ == "__main__":
    main()

from PyQt6.QtCore import Qt
from PyQt6.QtGui import QIcon
from PyQt6.QtWidgets import QApplication, QMainWindow, QStyle, QToolBar


def main():
    import sys

    app = QApplication(sys.argv)

    toolbar = QToolBar()
    toolbar.setToolButtonStyle(Qt.ToolButtonStyle.ToolButtonTextUnderIcon)

    icon = app.style().standardIcon(QStyle.StandardPixmap.SP_DesktopIcon)
    toolbar.addAction(icon, "desktop")

    w = QMainWindow()
    w.addToolBar(Qt.ToolBarAreas.LeftToolBarArea, toolbar)
    w.show()

    sys.exit(app.exec())


if __name__ == "__main__":
    main()
