property OnOpen : TOnInfoWindowOpen;
This event is raised just before the window display, you can change the contents or cancel opening
...
procedure TForm.doOnOpenWindow(const infoWindow: TECShapeInfoWindow; var cancel: boolean);

Using an animation of type TECAnimationAutoHide you can close the window automatically after a few seconds.
...
win: = map. addInfoWindow (lat, lng);
// automatically close the window after 15 seconds
win.Animation := TECAnimationAutoHide.Create;
TECAnimationAutoHide (win.Animation).MaxTiming := 1000 * 15;
Link
You can set a link by using the <a> tag, to intercept the click Connect on the OnBeforeUrl event of your map.
