Question

我正在尝试使用PyQt为一段python代码创建一个GUI。然而，由于我不知道的原因，GUI似乎切断了两个Qlabels的末尾。我已经解决了类似问题的Stack Overflow上的其他问题，但我找不到针对我的具体问题的修复。

最初它工作正常。但是在一切之后，我在GUI中添加了一个状态栏，并且必须将所有内容都降低一些。在我移动了所有内容后，文本开始从最后切断。我确实试图扭转过程，但没有帮助。

我附上了输出的截图：

以下是GUI的完整代码：

注意： 我删除了文本摘要代码的部分内容，因为这是保密的。我很确定这与被删除的文本无关，因为这纯粹是一个后端程序。此外，窗口中间有一个公司徽标（png文件），但我已将其删除以保持机密性。

如果您希望QLabel符合文字，那么您必须使用adjustSize()，在您的情况下：

self.input_label.adjustSize()
self.output_label.adjustSize()
