MeteoInfoLab脚本示例：用户界面-地图

MeteoInfo

MeteoInfoLab脚本开发用户界面程序用到了Java的Swing图形界面库，Jython对Swing的调用代码比Java更简洁一些，网上也有一些入门的教程。这个示例脚本创建一个JFrame对象（用户界面的图形窗体），在里面加上菜单、工具栏、以及一个mipylib.plotlib.figure模块里的Figure对象，利用add_axes函数添加一个MapAxes对象，然后用该对象的webmap和geoshow函数添加网络地图图层和中国省级行政界限图层。工具栏中包括了添加图层、地图缩放、地图要素属性显示等工具按钮。
