主要用到函数说明:
MxDrawXCustomEvent::MxDrawXCustomEntity::moveGripPointsAt
自定义实体事件,自定义实体夹点被移动,详细说明如下:
参数 | 说明 |
---|---|
LONGLONG lEntity | 自定义实体id |
IN LONG lGridIndex | 夹点索引号 |
IN McGePoint3d vec | 夹点移动的向量 |
VB代码实现如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 | If sEventName = "MxDrawXCustomEntity::moveGripPointsAt" Then Dim param88 As MxDrawResbuf Set param88 = MxDrawX1.CustomEventParam() Set customEntity = MxDrawX1.CallEx( "Mx_GetCustomEntity" , param88) Set sPt = customEntity.GetPoint( "startpoint" ) Set ePt = customEntity.GetPoint( "endpoint" ) Dim lIndex As Long lIndex = param88.AtLong(1) Dim offsetPt As MxDrawPoint Set offsetPt = param88.AtPoint(2) If lIndex = 0 Then sPt.x = sPt.x + offsetPt.x sPt.y = sPt.y + offsetPt.y customEntity.SetPoint "startpoint" , sPt Else ePt.x = ePt.x + offsetPt.x ePt.y = ePt.y + offsetPt.y customEntity.SetPoint "endpoint" , ePt End If End If |
