我对JDialog有些问题。我在NetBeans中创建了Swing GUI。 GUI包含带有按钮,文本字段等的主框架。当我单击“下一步”按钮时,将显示JDialog(在NetBeans中创建aslo,其他组件部分)。 以下是此JDialog的自定义属性:
问题在于,在Windows XP(也可能是7个)上,当JDialog发生时,我无法通过最小化父表单来最小化应用程序。在Ubuntu上,它按预期工作,但在Windows上没有。
我调查了http://docs.oracle.com/javase/tutorial/uiswing/misc/modality.html 这个例子也在研究Ubuntu和Widows。所以,我尝试手动创建示例JDialog,就像在demo中一样。而且Ubuntu再次在woking,在Windows上不是。
有人有任何想法吗?我还没有。
SAmple DEMO,在Ubuntu上工作,不在Windows XP上工作:

请尝试以下评论
你只需使用这个构造函数JDialog(Parent,Title,model)
jDialog1 = new javax.swing.JDialog(this, "Test", false);
并删除设置modalityType的行。
jDialog1.setModalityType(java.awt.Dialog.ModalityType.APPLICATION_MODAL);
我希望它会有所帮助。
(请注意,当你最小化JFrame时,孩子的JDialog也会被最小化)

这里的问题是你对模态对话应该如何运作的期望,而不是Swing使用的实现。
在不同操作系统上描述的行为是正确的。在Windows操作系统上,当表单显示为模态时,它应该完全禁用父窗口及其子窗口,以防止与其任何控件进行任何交互。您可以在打开的对话框和“您确定”退出对话框中的记事本中看到此行为。
