所以我想解决这个问题，在这个代码中创建了两个标签Account，Voicemail。帐号页面大小（501,847），相同大小的语音邮件页面，所以我想要解决这个问题。当我选择语音邮件选项卡时，页面大小应根据该页面中的内容调整大小。
答案 0 :(得分：0)
您可以使用更改选项卡时发出的QTabWidget.currentChanged()信号，然后根据选项卡调整窗口大小，例如：
self.yourTabWidget.currentChanged.connect(self.tab_changed)
def tab_changed(self):
if self.yourTabWidget.currentIndex == 0:
self.setGeometry(x, x, x, x) # size for first tab
elif self.yourTabWidget.currentIndex == 1:
self.setGeometry(x, x, x, x) # size for second tab
在第一个标签测量开始时使用self.setGeometry()
如果您也不想更改位置，可以使用self.resize()代替self.setGeometry()
