我正在尝试使用 PyQt 为一段 python 代码制作一个 GUI。 但是，由于我不知道的原因，GUI 似乎切断了两个 Qlabel 的末端。我已经针对类似问题浏览了 Stack Overflow 上的其他问题，但没有找到针对我的特定问题的解决方案。
最初它工作正常。但在这一切之后，我在我的 GUI 中添加了一个状态栏，并且不得不将所有内容向下移动一些。在我移动了所有内容之后，文本开始从末尾被切断。我确实尝试过逆转这个过程，但没有帮助。
我附上输出的屏幕截图:

最佳答案
如果您希望 QLabel 适合文本，那么您必须使用 adjustSize()，在您的情况下:
self.input_label.adjustSize()
self.output_label.adjustSize()

关于python - Qlabels 在最后被剪掉，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48665788/
