如何使pyqt gui刷新

Question

I am making a GUI in pyqt which gets battery levels for a robot and then displays them. The GUI would therefore have to constantly update its battery level displays (which are displayed using QProgressBar).

However, if I were to put the progress bars in a loop, it makes infinite copies of the graphics and stacks them on top of each other. How might I make the progress bars refresh without making additional copies? Is there a way to delete everything in the loop after each recurrence?

将进度条设为全局变量，并让另一个线程调用更新进度方法，不要复制进度条本身。
