例如: JS;
function DoCommandEventFunc(iCmd)
{
if (iCmd == 1)
{
var mxOcx = document.all.item("MxDrawXCtrl");
mxOcx.focus();
var point1 = mxOcx.GetPoint(false,0,0,"n 点取开始点:");
if(point1 == null)
{
return;
}
var point2 = mxOcx.GetPoint(true,point1.x,point1.y,"n 点取结束点:");
if(point1 == null)
{
return;
}
mxOcx.DrawLine(point1.x,point1.y,point2.x,point2.y);
}
}
document.getElementById("MxDrawXCtrl").ImplementCustomEvent = CustomEvent;
document.getElementById("MxDrawXCtrl").ImplementMouseEventFun = MouseEvent;
document.getElementById("MxDrawXCtrl").ImplementCommandEventFun = DoCommandEventFunc;
