[PyQt] Issue with Qt.Drawer in PyQt5

[Thomas Robitaille]

Hi everyone,

I am trying to create a Drawer widget - in PyQt4 this works fine:

from PyQt4 import QtCore, QtGui
app = QtGui.QApplication([])
window = QtGui.QWidget()
drawer = QtGui.QWidget(window)
drawer.setWindowFlags(QtCore.Qt.Drawer)
window.show()
drawer.show()
app.exec_()

However, if I try the same in PyQt5, I get a standalone pop-up window
and not a drawer:

from PyQt5 import QtCore, QtWidgets
app = QtWidgets.QApplication([])
window = QtWidgets.QWidget()
drawer = QtWidgets.QWidget(window)
drawer.setWindowFlags(QtCore.Qt.Drawer)
window.show()
drawer.show()
app.exec_()

Does anyone know what could be happening here?

Thanks!
Tom
