我正在处理一个简单的GUI,它输出一个自动复制到剪贴板的数值。我试图在发生这种情况时立即将“复制”文本闪烁,立即显示,然后在一两秒后消失。
文本会按照我的要求闪烁,但显示的输出字段在文本消失之前不会更新,这不是我编写脚本的顺序。目标是让输出字段看起来在文本出现的同一时刻更新。
我出现文字的方式相当粗糙,所以我对建议很开放。意见和评论将不胜感激。

你只需要强制重绘,否则它不会重新绘制,直到调用下一个EVT_PAINT(在函数退出...之后)睡眠阻塞...这意味着在睡眠时根本没有执行任何代码< / p>
...
self.label3.SetLabel("Copied")
self.Update()#force redraw
....
