（Java）如果我在其外面点击，JPopupMenu将不会关闭

时间：2010-04-18 12:26:45

标签： java

我创建了一个Java Swing应用程序，该应用程序没有可见的主窗口，但通过右键单击可以通过托盘图标进行控制。

我正在使用JPopupMenu，但是当我点击弹出菜单之外（例如在另一个应用程序的窗口或桌面上）时，JPopupMenu不会消失，这不是预期的行为。

最初我使用的popupMenu按预期工作，但这不允许我在菜单中显示图标。

当我点击其他地方时，如何按预期将其关闭？

谢谢！

//_Popup is your JPopupMenu, call this method before setting your popup to visible
public void armPopup()
{
    if(_Popup != null)
    {
        Toolkit.getDefaultToolkit().addAWTEventListener(new AWTEventListener()
        {
            @Override
            public void eventDispatched(AWTEvent event) {

                if(event instanceof MouseEvent)
                {
                    MouseEvent m = (MouseEvent)event;
                    if(m.getID() == MouseEvent.MOUSE_CLICKED)
                    {
                        _Popup.setVisible(false);
                        Toolkit.getDefaultToolkit().removeAWTEventListener(this);
                    }
                }
                if(event instanceof WindowEvent)
                {
                    WindowEvent we = (WindowEvent)event;
                    if(we.getID() == WindowEvent.WINDOW_DEACTIVATED || we.getID() == WindowEvent.WINDOW_STATE_CHANGED)
                    {
                        _Popup.setVisible(false);
                        Toolkit.getDefaultToolkit().removeAWTEventListener(this);
                    }
                }
            }

        }, AWTEvent.MOUSE_EVENT_MASK | AWTEvent.WINDOW_EVENT_MASK);

    }
}

使用JPopupMen时出现错误：JTrayIcon: support Swing JPopupMenus for tray icons。接近结尾是可能的解决方案的链接。我没有尝试过，所以我不知道它是否会解决你的问题。

答案 2 :(得分：2)

最后，我通过解决问题“解决”了这个问题。正如卡米克所指出的那样，JPopupMenu非常多。然而，它是唯一的Swing弹出菜单实现，允许您在每个菜单元素旁边有一个图标。

我的解决方案是在jpopupmenu上实现一个监听器，如果用户将鼠标放在菜单上，3秒后，如果用户没有将鼠标放回菜单上，它将被设置为.isVisible（false）在那段时间内。

为了实现这一点，我不得不使用一个单独的线程，它不断检查popupmenu是否处于活动状态。如果是这样，请检查鼠标是否在其上，使用事件侦听器，如果用户未在3秒内再次输入，则将可见性设置为false。

这不是一个完美的解决方案，因为用户仍然需要等待3秒才能使菜单消失（如果他/她点击它就应该是即时的）并且即使它处于焦点也会消失（除非它不应该消失）用户点击了）。然而，感觉“足够好”被接受了。

希望有所帮助。

答案 3 :(得分：0)

我最近正为这个“旧”问题而苦苦挣扎。这是我的解决方案，效果很好，符合我的期望。

我在托盘图标类中添加了一个未经装饰的透明窗口，并在其上附加了一个FocusListener。当触发显示弹出窗口时，鼠标事件也会触发显示透明窗口（由于透明而无法看到）。窗口获得焦点获得事件。在弹出窗口之外的屏幕上单击鼠标时，将触发透明窗口的focusLost事件。现在，此事件用于将弹出窗口设置为不可见。
