toolbar

<P>开发语言c#.</P>
<P>功能.自己开发的command或着tool可以加上.</P>
<P>问题.为什么我的写的command或着tool采用toolbarcontrol.additem();之后不能用啊.所有的事件比如onclick等,不能实现啊.</P>

能不能再详细点?多谢！

<P>首先，你定义的m_mapControl跟你自己界面中的mapcontrol没有建立起联系，需要用hook来建立，或者将主界面窗体实例化，获取它的mapcontrol。</P>
<P>其次，需要类的初始化和对象释放。</P>

<P>我C＃不熟悉，但是你的类应该这样写</P>
<P>using System;</P>
<P>using ESRI.ArcGIS.Utility.BaseClasses;<BR>using ESRI.ArcGIS.Carto;<BR>using ESRI.ArcGIS.MapControl;<BR>using ESRI.ArcGIS.ControlCommands;</P>
<P>namespace mytool<BR>{<BR> /// <summary><BR> /// Summary description for Full.<BR> /// </summary><BR> public class Full:BaseCommand<BR> {<BR>  private IHookHelper m_hook1=new HookHelperClass();</P>
<P>  public Full()<BR>  {<BR>   //<BR>   // TOD Add constructor logic here<BR>   //<BR>   base.m_caption = "full";<BR>   base.m_name ="full";<BR>            base.m_message="full";<BR>   base.m_toolTip="full";<BR>   base.m_enabled=true;<BR>            <BR>  }<BR>  public override void OnClick()<BR>  {<BR>   m_hook1.ActiveView.Extent = m_hook1.ActiveView.FullExtent;   <BR>  }<BR>  public override void OnCreate(System.Object hook)<BR>  {<BR>   m_hook1.Hook=hook;<BR>  }</P>
<P>  <BR> }<BR>}</P>

<P>using System;<BR>using ESRI.ArcGIS.Utility.BaseClasses;<BR>using ESRI.ArcGIS.Carto;<BR>using ESRI.ArcGIS.MapControl;</P>

<P>把相关代码发上来看看</P>
