我英语不好，所以文档对我没有帮助，我在俄语论坛上找不到合适的解决方案。
问题的症结在于我有几个小部件（两个 QLabels，QLineEdit 和 QTimeEdit），我希望它们在调整窗口大小时根据更改进行缩放，但同时它们必须相对于每个小部件保持在相同的位置其他。那些。例如，我希望在两个 QLabel 等之间具有相同的可扩展空白空间。
我附上整个项目的代码，我感兴趣的窗口在AppendWindow类中，它继承了Ui_Append类的UI。

使用固定几何很少是一个好主意。布局管理器，例如
QGridLayout，确保您的界面始终针对任何窗口分辨率进行优化，考虑到所有小部件用于计算其大小的字体和样式，并确保它们始终正确显示而不会相互重叠。
