GMLib Waypoint和演示

Question

我尝试了这段代码，但没有显示路点

这段代码工作得很好，但是我不能再添加第三个地方

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

但这一次，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;

我的地图仍然是空的，有人能帮我吗？

Answer 1

你需要做的是

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;
