从框架中获取鼠标单击的坐标

我的基本问题是，我有一个内部框架，其中有一个地图显示in.And我想要获得该地图上的点击坐标，所以我可以绘制一个Waypoints到那张地图。但基本上我得到的是什么都没有。 getX和getY只在我点击该地图之外的地方（内部框架内）时才返回坐标。手动添加航点正常工作。继承人我的代码：从框架中获取鼠标单击的坐标

这听起来像JXMapKit被消耗鼠标事件，他们到达内部帧之前。

将鼠标事件想象为雨滴，并将鼠标听作雨伞。如果在你上方打开一把雨伞，那么雨滴将不会触及你。

，而不是添加鼠标侦听器，内部框架，你需要将它们添加到JXMapKit实例

Goint尝试。 – 2013-02-08 14:33:55

我将它添加到JXMapKit并没有发生任何事情 – 2013-02-08 14:47:40

Finnaly经过数小时的尝试，我发现了一个解决方案。代替这样做> hlavnaMapa.getMap（）。addMouseListener（handler）;我必须这样做> hlavnaMapa.getMap（）。getMainMap（）。addMouseListener（handler）; 。我的想法很好，MouseListener无法从动态内容中点击点击。最后，点击效果很好 – 2013-02-08 16:49:58
