插件的开发方法2004-8-24一、创建插件接口1.1 头文件如：#ifndef CAAIAfrGeoCreationWkbAddin_h#define CAAIAfrGeoCreationWkbAddin_h// ApplicationFrame Framework#include <CA TIWorkbenchAddin.h>// Needed to derive from CATIWorkbenchAddin// Local Framework#include "CAAAfrGeoCreationWbench.h" // Needed to export the IID// Global Unique IDentifier defined in .cpp// exported by CAAAfrGeoCreationWbenchextern IID ExportedByCAAAfrGeoCreationWbench IID_CAAIAfrGeoCreationWkbAddin;class ExportedByCAAAfrGeoCreationWbench CAAIAfrGeoCreationWkbAddin : public CATIWorkbenchAddin {// Used in conjunction with CATImplementInterface in the .cpp fileCA TDeclareInterface;public:};#endif1.2 源文件1.2.1 组成1）接口标识符（IID）构造2）接口实现1.2.2 实例如：#include <CAAIAfrGeoCreationWkbAddin.h>// Use uuid_gen -C on UNIX or uuidgen -s on NT to generate the IIDIID IID_CAAIAfrGeoCreationWkbAddin = { /* a4188b88-d4c1-11d3-b7f5-0008c74fe8dd */0xa4188b88,0x11d3,{0xb7, 0xf5, 0x00, 0x08, 0xc7, 0x4f, 0xe8, 0xdd}};// Declares that CAAIAfrGeoCreationWkbAddin is an interface that// OM-derives from CATIWorkbenchAddinCATImplementInterface(CAAIAfrGeoCreationWkbAddin, CATIWorkbenchAddin);1.3 TIE文件1.3.1 内容头文件引用1.3.2 实例如：// Used by mkmk to create TIE_CAAIAfrGeoCreationWkbAddin.h#include <CAAIAfrGeoCreationWkbAddin.h>详见《接口开发》二、插件开发2.1 头文件2.1.1 结构#ifndef <插件类>_H#define <插件类>_H// System framework#include "CATBaseUnknown.h" // Needed to derive from CATBaseUnknown// ApplicationFrame framworkclass CATCmdContainer;
