Java Swing - 使JFrame表现得像一个对话框

Question

我有一个主框架和一个附加的可折叠面板，我从http://sourceforge.net/apps/wordpress/miasct/2009/03/29/external-collapsible-panel/获得。 问题是可折叠面板创建未修饰的框架，扩展JFrame（实际上是来自SwingX的JXFrame）并且表现得像一个。

1. 我如何摆脱这个：



1. 不要在alt + tab thingy中显示
2. 当我在WindowsOS中使用“最小化所有窗口”然后最大化主框架时，附加的框架会保持图标化。

以下是代码：

import com.sun.jna.platform.WindowUtils;
import java.awt.Point;
import java.awt.Shape;

import java.awt.event.ComponentAdapter;
import java.awt.event.ComponentEvent;
import java.awt.geom.Ellipse2D;
import java.awt.geom.RoundRectangle2D;
import javax.swing.JFrame;

import org.jdesktop.swingx.JXFrame;
import ui.MainFrame;

                    y = p.y - getHeight();
                    break;

                case BOTTOM:
                    p = parentFrame.getLocationOnScreen();
                    x = p.x;

            setLocation(x, y);

提前致谢。

不太好的想法同时持有两个JFrames（或其SwingX衍生物），你必须改变未装饰的JDialog或JWindow（其SwingX衍生物），解决三个问题，你可以正确设置

• setParent

• setModal，ModalityTypes

• WinOS中没有iconified
