GMLib Waypoint abd展示了它们

Question

我尝试使用此代码，但是航点不显示

此代码完美无缺，但我无法添加第三个

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

但这一个，根本不是

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;

我的地图仍然绝望地空着 有人可以帮帮我吗？

Answer 1

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;

此致
