在“世界风”中单击时禁用地球仪移动

我正在尝试在“世界风”中单击鼠标禁用地球仪的移动。我期望能够做到：

void disableGlobeDrag(WorldWindowGLCanvas ww) {
    ww.addMouseMotionListener(new MyMouseMotionListener());
}

where MyMouseMotionListener消耗所有鼠标事件。这不起作用，所以我必须这样做：

void disableGlobeDrag(WorldWindowGLCanvas ww) {
    for(MouseMotionListener l : ww.getMouseMotionListeners()) {
        if(l.getClass().toString().equals("class gov.nasa.worldwind.awt.AWTInputHandler")) {
            ww.removeMouseMotionListener(l);
        }
    }
}

消耗的鼠标事件是否仍应到达gov.nasa.worldwind.awt.AWTInputHandler听众？

Update: WorldWindowGLCanvas正在打电话addMouseMotionListener() on java.awt.Component所以显然我不明白消费事件是如何工作的。

更新2：尽管与 Swing 共享接口，但调用WorldWindowGLCanvas.removeMouseMotionListener() with AWTInputHandler因为论证会阻止所有其他MouseMotionListeners 来自接收事件。添加和删​​除方法AWTInputHandler应该使用。

不幸的是删除了MouseMotionListener正如 @trashgod 所建议的那样，这不起作用，因为发生了一些 World Wind 特定行为：删除gov.nasa.worldwind.awt.AWTInputHandler导致其他MouseMotionListeners 停止接收事件通知。

禁用地球仪拖动并仍然在另一个中接收事件MouseMotionListener需要采取以下步骤：

获取 World Wind 的参考AWTInputHandler:

AWTInputHandler wwHandler = null;
// get World Wind's AWTInputHandler class:
for (MouseMotionListener l : ww.getMouseMotionListeners()) {
    if(l instanceof AWTInputHandler) {
        wwHandler = (AWTInputHandler)l;
        break;
    }
}

创建一个MouseMotionListener它消耗事件：

public class MyMouseMotionListener implements MouseMotionListener {
    @Override
    public void mouseDragged(MouseEvent e) {
        // consume the event so the globe position does not change
        e.consume();
        if (e.getSource() instanceof WorldWindowGLCanvas) {
            // get the position of the mouse
            final WorldWindowGLCanvas canvas = ((WorldWindowGLCanvas) e.getSource());
            final Position p = canvas.getCurrentPosition();
            // do something with the position here
        }
    }
    @Override
    public void mouseMoved(MouseEvent e) {
        e.consume();
    }
}

添加鼠标移动监听器AWTInputHandler:

if(wwHandler != null) {
    wwHandler.addMouseMotionListener(new MyMouseMotionListener());
} else {
    // I don't think this should happen unless the AWTInputHandler
    // is explicitly removed by client code
    logger.error("Couldn't find AWTInputHandler");
}

也就是说，我不知道为什么WorldWindowGLCanvas正在使用Component.addMouseMotionListener()而不是AWTInputHandler.addMouseMotionListener().
