我正在设计一个 Pyside Qt 应用程序，我想在我的主窗口中切换 QtCore.Qt.WindowStaysOnTopHint 窗口标志。使用以下代码设置此提示可以正常工作：
self.setWindowFlags(QtCore.Qt.WindowStaysOnTopHint)
self.show()
但是我不知道如何使用Pyside移除窗口标志。
有人知道如何做吗？

通常情况下，窗口标志会与现有标志一起进行OR运算：
print(int(self.windowFlags()))
self.setWindowFlags(self.windowFlags() | QtCore.Qt.WindowStaysOnTopHint)
print(int(self.windowFlags()))
然后要移除标志，使用该标志的否定进行 AND 运算：
self.setWindowFlags(self.windowFlags() & ~QtCore.Qt.WindowStaysOnTopHint)
print(int(self.windowFlags()))

你可以像这样切换窗口的显示位置：在顶部或底部。
def toggleFunc(self):
if self.someCheckedButton.isChecked(): #show up at the top
self.setWindowFlags(self.theMainWindow.windowFlags() | QtCore.Qt.WindowStaysOnTopHint)
else: #show up at the bottom
self.setWindowFlags(self.theMainWindow.windowFlags() & ~QtCore.Qt.WindowStaysOnTopHint)
self.show() #it's important to show up the window again after changing the window flags

self.show()，我一直在寻找。这个答案被低估了。 - William Brochensque junior0
