Qt单选按钮开关显示延迟
我这里有一个 Qt 应用程序，其中有一个主窗口，其中有 5 个垂直对齐的 QPushButton。 这些按钮以单选组的方式工作。 这意味着它们是可检查的且自动排他的。 由于我需要能够在主窗口调整大小时调整按钮文本的字体大小，因此我包含了自己的 QPushButton 覆盖并将其设置为设计器中的自定义小部件。
我不明白的是，当我通过键盘快捷键从一个按钮切换到另一个按钮时，会出现严重的延迟！当我用鼠标点击时也是如此。 我想说这个延迟大约是0.5到1秒。 在不同的机器上尝试过。
我真的需要摆脱这个！
任何人都知道我可以做些什么来解决这个问题？
编辑：刚刚发现当我只使用普通的 QPushButtons 时，这种行为是相同的。似乎按钮越大，延迟就越多。强烈感谢任何帮助！
I'm having a Qt application here where I have a main window with 5 QPushButtons that are aligned vertically.
These buttons work in a radio-group manner.
This means, that they are checkable and auto-exclusive.
Since I need to be able to resize the font size of the button text when the main window resizes, I included my own override of QPushButton and set it as custom widget in designer.
What I don't understand is, that there is a heavy delay when I switch from one button to another via keyboard shortcuts! Same when I click with the mouse.
I would say that this delay is about 0.5 to 1 second.
Have tried it on different machines.
I really need to get rid of this!
Anyone has an idea of what I could do to fix this??
Edit : Just found out that this behavior is the same when I just use normal QPushButtons. It seems that the delay is getting more when the buttons are getting bigger. Any help is strongly appreciated!!!

黑暗中的一枪：设置字体可能会导致另一个 resizeEvent，这又会导致另一个 resizeEvent，依此类推...尝试将字体调整代码放入您进入/离开全屏模式时显式调用的方法中。
A shot in the dark: Setting the font might cause another resizeEvent, which in turn causes another one and so on... Try putting the font adjustment code into a method that you explicitly call when you enter/leave full screen mode.
