java dialog 关闭_java – 等待jdialog关闭

同样,关键是对话模式与否？

如果它是模态的,则不需要WindowListener,因为您将知道对话框已被处理,因为代码将在对话框的setVisible(true)调用之后立即恢复.即,这应该工作：

projectDialog = new FilePathDialog();

projectDialog.setVisible(true);

doWork(); // will not be called until the dialog is no longer visible

另一方面,如果它没有模式,则WindowListener应该可以工作,并且您可能在此处未显示的代码中遇到另一个问题,并且您将要发布sscce以供我们分析,运行和修改.

请查看此SSCCE,它显示3种类型的默认关闭参数将触发窗口监听器：
