Yes, I two buttons (Zoom+ and Zoom-) should behave exactly like those of the your "zoom control".
In addition there is a "C" button (top left) which should center the map.
The navigator TwoNav has just these 3 buttons that disappear when the map stops and they appear when it is moved.
Actually, for some reason unknown to me now, the event ZoomChanged and is not trapped ZoomChanged. the code
Sub MapView1_ZoomChanged
Log("MapView1_ZoomChanged")
LbZoom.Text = "Z"&CStr(MapView1.Zoom)
End Sub
is not executed (MapView1 is declared in Sub Globals)
???
Maybe everything would be resolved if we could intercept the event MapView1_Move (which does not exist !)
