标签在移动窗口pyqt5后更改位置>

Question

我有这个窗口，其中主布局是带有嵌套QVBoxlayout的QHBoxlayout

出于某种原因，在顶部上设置了两个标签用鼠标移动窗口或调整窗口大小后，pressen_label = qtw.QLabel("Choose A")标签正在更改其位置。

使用鼠标移动/更改窗口大小之前

移动窗口后

如何锁定标签的位置使其不移动？

pressen_label = qtw.QLabel("Choose  A")
quality_label = qtw.QLabel("Choose  B")
hblayout_labelcombo = qtw.QHBoxLayout()
hblayout_labelcombo.addWidget(pressen_label)
hblayout_labelcombo.addStretch(1)
hblayout_labelcombo.addWidget(quality_label)
hblayout_labelcombo.addStretch(10)
hblayout_labelcombo.setAlignment(qtc.Qt.AlignTop)

描述您的错误可能很复杂（甚至浪费时间），例如quality_label被添加到3种布局中：hblayout_labelcombo.addWidget(quality_label)，hblayout_labelmsslayout.addWidget(quality_label)和hblayout_mssbuttonlayout.addWidget(quality_label)这是不合逻辑的。
