问题描述
研究问题时,似乎大多数人都想做相反的事情(即删除最小化/关闭"按钮).使用反复出现的setUndecorated
和setDefaultCloseOperation
When researching the problem, it seems most people are wanting to do the opposite (i.e remove the minimize/close button).I've had no success using the reoccurrent setUndecorated
and setDefaultCloseOperation
这是我的代码:
private class TestDialog extends JDialog
{
public static final String title_ = "Test Dialog";
public TestDialog(JFrame parent)
{
super(parent,title_,true);
setMinimumSize(new Dimension(500,500));
setLocationRelativeTo(null);
setUndecorated(false);
setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
}
}
显示对话框时,我得到以下信息:
When I display the dialog I get the following:

推荐答案
目前尚不清楚问题可能出在哪里,但是下面的完整示例可在Ubuntu 12,Java 6上运行;它可以帮助您确定问题所在.请注意, all 顶级容器事件分配线程上构建.
It's not clear where things may have gone awry, but the complete example below works on Ubuntu 12, Java 6; it may help you pin down the problem. Note that all top-level containers must be constructed on the event dispatch thread.
import java.awt.Dimension;
import java.awt.EventQueue;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.WindowConstants;
public class TestDialog extends JDialog {
public static final String title = "Test Dialog";
public TestDialog(JFrame parent) {
super(parent, title, true);
add(new JPanel(){
@Override
public Dimension getPreferredSize() {
return new Dimension(320, 240);
}
});
pack();
setLocationRelativeTo(null);
setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
new TestDialog(null).setVisible(true);
}
});
}
}
