PyQt6 的 Qt 模块替代品 [英] Qt module alternative for PyQt6
问题描述
我只是将我的应用程序从 PyQt5 迁移到 PyQt6.我知道 Qt 模块已在 Qt6 中删除.我有诸如Qt.AlignCenter"、Qt.ToolButtonTextUnderIcon"、Qt.LeftToolBarArea"之类的东西,它们不再起作用.Qt6 中是否有此功能的替代方案?
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?
推荐答案
Qt 模块只存在于 PyQt5 中(Qt5 中没有),它允许访问任何子模块的任何类或元素,例如:
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
该模块与属于 QtCore 模块的 Qt 命名空间不同,因此如果要访问 Qt.AlignCenter,则必须从 QtCore 导入 Qt:
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()
