delphi-xe2 - GMLib Waypoint abd 向他们展示

Question

我试试这段代码，但航点不显示

此代码完美运行，但我无法添加第三个位置

GMDirection1.DirectionsRequest.Origin.Address := 'My spot 1';
GMDirection1.DirectionsRequest.Destination.Address := 'My spot 2';
GMDirection1.Execute;

但是这个，一点也不

GMDirection1.DirectionsRequest.WaypointsList.Add.Location.Address := 'My spot 1';
GMDirection1.DirectionsRequest.WaypointsList.Add.Location.Address := 'My spot 2';
GMDirection1.DirectionsRequest.WaypointsList.Add.Location.Address := 'My spot 3';
// or GMDirection1.AddWaypoint.Location.Address := 'My spot';
// I try all Waypoint.Add unsuccessful
GMDirection1.Execute;

我的地图仍然空空如也有人可以帮助我吗？

你需要做

GMDirection1.DirectionsRequest.Origin.Address := 'My spot 1';
GMDirection1.DirectionsRequest.Destination.Address := 'My spot 3';
GMDirection1.DirectionsRequest.WaypointsList.Add.Location.Address := 'My spot 2';
GMDirection1.Execute;
