JDialog阻止Windows上的父窗口 [英] JDialog blocks parent window on Windows
问题描述
我对JDialog有一些问题.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的其他组件"部分中创建的aslo). 以下是此JDialog的自定义属性:
I have some problem with JDialog. I have Swing GUI created in NetBeans. GUI contains main frame with buttons, text fields, etc. When I click 'Next' button then JDialog (created aslo in NetBeans, Other Components section) is showing. Below are custom properties for this JDialog:
- modal = true;
- resizable = false;
- 默认关闭操作=丢弃
问题在于，在Windows XP(可能也是7)上，当出现JDialog时，我无法通过最小化父窗体来最小化应用程序.在Ubuntu上，它可以按预期运行，但在Windows上却不能.
The problem is that, on Windows XP (probably 7 too), when JDialog occurs then I can't minimalize application by minimalize parent form. On Ubuntu it is working as expected, but on Windows doesn't.
我查看了 http://docs.oracle.com/javase/tutorial/uiswing/misc/modality.html 这个例子也适用于Ubuntu和Widows.因此，我尝试像在演示中一样手动创建示例JDialog.再次在Ubuntu上可以正常工作，而在Windows上则不能.
I have look into http://docs.oracle.com/javase/tutorial/uiswing/misc/modality.html and this example is working on Ubuntu and Widows as well. So, I tried to create sample JDialog manually as in it demo. And again on Ubuntu is woking, on Windows is not.
有人有什么主意吗?我还没有.
COuld someone have any idea? I have not any already.
在DEMO上运行的大量DEMO，在Windows XP上不运行:

推荐答案
请尝试以下注释
您仅使用此构造函数JDialog(父，标题，模型)
you just use this constructor JDialog(Parent, Title, model)
jDialog1 = new javax.swing.JDialog(this, "Test", false);
并删除设置modalityType的行.
and remove the line which sets modalityType .
jDialog1.setModalityType(java.awt.Dialog.ModalityType.APPLICATION_MODAL);
希望对您有所帮助.
(请注意，当最小化JFrame时，子JDialog也将最小化)
(Please note that when you minimize tha JFrame the child JDialog will also get minimized)
