I am trying to put together a c# program with GMap, and I'd like the coordinates where the mouse is to show up on the bottom of the screen. I've added an OnMouseMove method to the form, and I do get coordinates out, but only if the mouse is not over the map itself. If the mouse is over the map it does not respond. I am fairly new to c#, so I am probably missing something fairly simple. Any ideas? Below is the code I'm using right now.
public partial class Form1 : Form
{
protected override void OnMouseMove(System.Windows.Forms.MouseEventArgs e)
{
base.OnMouseMove(e);
if(e.Button == MouseButtons.Left)
{
int itest=2;
}
double X = mapexplr.FromLocalToLatLng(e.X, e.Y).Lng;
double Y = mapexplr.FromLocalToLatLng(e.X, e.Y).Lat;
string longitude = X.ToString();
string latitude = Y.ToString();
LongStrip.Text = longitude;
LatStrip.Text = latitude;
}
GMapOverlay overlayOne;
public Form1()
{
InitializeComponent();
}
private void mapexplr_Load(object sender, EventArgs e)
{
//initialisation de notre map
mapexplr.MapProvider = GMap.NET.MapProviders.BingMapProvider.Instance;
GMap.NET.GMaps.Instance.Mode = GMap.NET.AccessMode.ServerAndCache;
mapexplr.Position = new PointLatLng(35.571458, -85.547961);
mapexplr.DragButton = MouseButtons.Left;
mapexplr.SetCurrentPositionByKeywords("Tunisia");
mapexplr.MapProvider = GMapProviders.BingMap;
mapexplr.MinZoom = 3;
mapexplr.MaxZoom = 17;
mapexplr.Zoom = 5;
mapexplr.Manager.Mode = AccessMode.ServerAndCache;
//ajout des overlay
overlayOne = new GMapOverlay(mapexplr, "OverlayOne");
//ajout de Markers
overlayOne.Markers.Add(new GMap.NET.WindowsForms.Markers.GMapMarkerGoogleGreen(new PointLatLng(36.657403, 10.327148)));
//ajout de overlay à la map
mapexplr.Overlays.Add(overlayOne);
}
}
private void gMapControl1_MouseMove(object sender, MouseEventArgs e)
{
lat = gMapControl1.FromLocalToLatLng(e.X, e.Y).Lat;
lng = gMapControl1.FromLocalToLatLng(e.X, e.Y).Lng;
label1.Text = "lat= " + Convert.ToString(lat)+ " lng= " +Convert.ToString(lng);
label1.BackColor = Color.Transparent;
mouseY = e.Location.Y;
mouseX = e.Location.X;
label1.Location = new Point(mouseX, mouseY+10);
