MxDrawXCustomEvent 接口

控件中的自定义事件说明得到事件参数，调用控件的CustomEventParam 设置事件返回数据,调用控件的Mx_SetEventRetEx

IDL

interface MxDrawXCustomEvent;

文件

MxDrawXCustomFunction.idl

备注

例如: C#下面的使用例子

 private void axMxDrawX1_CustomEvent(object sender, AxMxDrawXLib._DMxDrawXEvents_CustomEventEvent e)
        {
            System.String sTmp;

            if (e.sEventName == "SetTipCoord")
            {
                MxDrawResbuf pParam = (MxDrawResbuf)(axMxDrawX1.CustomEventParam());

                sTmp = pParam.AtString(0);


            }
            else if(e.sEventName == "SysVarChanged")
            {
                // 系统变量发生改事件.

                MxDrawResbuf pParam = (MxDrawResbuf)(axMxDrawX1.CustomEventParam());

                // 得到系统变量名.
                System.String sVarName =  pParam.AtString(0);

                if (sVarName == "ORTHOMODE")
                {
                    // 垂直输入变量发生改变，得到改变后的值.
                    MxDrawResbuf spVarValue
                        = (MxDrawResbuf)(axMxDrawX1.Call("GetSysVar", sVarName));

                    Int32 iOsmode = spVarValue.AtLong(1);

                    MxDrawUtility mxUtility = new MxDrawUtility();

                    mxUtility.Prompt("n" + sVarName + "值:" + iOsmode);

                }


            }
            else if(e.sEventName == "OpenFileComplete")
            {
                // 打开图纸结束事件.
               // MessageBox.Show("OpenFileComplete");
            }

            else if (e.sEventName == "MxDrawXInitComplete")
            {
                // 控件加载初始化完成.
                //MessageBox.Show("MxDrawXInitComplete");
            }

        }
