问题描述
请参阅此屏幕快照，在中间是由TVirtualStringTree控件生成的小提示窗口，这些提示窗口在屏幕上被忽略了，这些提示窗口将一直保留在那里，直到应用程序退出为止.当显示树视图的提示并且鼠标快速移到它旁边的窗口时，就会发生问题.
See this screenshot, in the middle it's the small hint windows that are generated by a TVirtualStringTree control and were left out on the screen, these hint windows will remain there until the application exits. the problem happens when the treeview's hint is shown and the mouse leaves quickly to the window next to it.
关于难以避免的任何想法，或者如果很难做到这一点，如何清除那些未擦除的提示窗口?
Any idea about how to avoid this or how to clear those un-erased hint windows if it's difficult to avid this?
几天前，我问了，尽管屏幕快照中的提示窗口看起来相同，但问题并不相同.这个问题，提示文本从不显示，仅显示未完成的提示窗口.提示文本显示了此问题，但是在某些情况下提示窗口没有被完全擦除(如上所述).希望一切都清楚.
Few days ago I asked a similar question, while the hint windows in the screenshots look the same, the are not the same problem. That problem, the hint text never shows and only that kind of uncompleted hint windows are shown; This problem, the hint text shows but the hint windows are not completely erased in a case (as I described above). Hope it's clear.
推荐答案
仅重新绘制窗口是否有帮助?
Does it help to just repaint the window?
