showMessageDialog 是没用的，因为它需要用户输入关闭。您需要使用 https://docs.oracle.com/javase/中所述的无模式对话框tutorial / uiswing / misc / modality.html [ ^ ]。 <pre lang="C#">

解决方案
showMessageDialog is no use because it needs user input to close. You need to use a Modeless dialog as described in https://docs.oracle.com/javase/tutorial/uiswing/misc/modality.html[^].这篇关于我需要帮助来调整定时器代码到我的代码的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
