Slider alignment

Question

I have problems aligning the Slider Widget in a Box Layout. I want to align it in the horizontal center, but it always remains on the left.

self.btnPerson = QPushButton("Person", self)
self.btnPerson.setAutoDefault(False)
self.btnPerson.setStyleSheet("background-color:rgb(189,255,189)")
self.editor = QTextEdit(self)
self.slider = QSlider(self)

vbox = QVBoxLayout()
vbox.addWidget(self.btnPerson)
vbox.addWidget(self.editor)
vbox.addWidget(self.slider,QtCore.Qt.AlignHCenter)
self.setLayout(vbox)

self.show()

Answer 1

因为python take参数默认取决于顺序，所以我认为Align Center传递给Stretch参数，所以请尝试以下操作：

vbox.addWidget(self.slider,alignment=QtCore.Qt.AlignHCenter)
