property OnOpen : TOnInfoWindowOpen;

This event is raised just before the window display, you can change the contents or cancel opening

win.OnOpen := doOnOpenWindow;
procedure TForm.doOnOpenWindow(const infoWindow: TECShapeInfoWindow; var cancel: boolean);
// set cancel to true for not open then infowindow (default false)
// cancel := true;

infoWindow.Content := 'change content here';

When a window is closed by clicking on his cross the event OnCloseInfoWindow of TECNativeMap is raised and a TECShapeInfoWindow is passed as a parameter.

OnCloseInfoWindow does not occur if you close by using the property visible



You can set a link by using the <a> tag, to intercept the click Connect on the OnBeforeUrl event of your map.

s := '<a href="#your_data"> link </a>';
OpenInfoWindow (s, Item.Latitude, Item.Longitude);


Procedure TForm.mapBeforeUrl (Sender: TObject; var Url: string);
// here url = '#your_data'

You have the option to set a special link that allows you to move around the map, it is of the form #zoom/latitude/longitude

'<a href="#16/43.094089/-0.046520"> goto here </a>'
