MapDisplayArea(MAP_MyMap, p1, p2, True, procEndAnimation)
INTERNAL PROCEDURE procEndAnimation(bResult is boolean)
IF bResult = True THEN
<Result> = MapDisplayArea(<Map control> , <North West position> , <South East position> [, <Animation> [, <WLanguage procedure>]])
- True if a request to change the position was made,
- False otherwise. To get more details on the error, use ErrorInfo.
<Map control>: Control name
Name of the Map control to be used. If this parameter corresponds to an empty string (""), the Map control to which the current process belongs will be used.

Name of the geoPosition variable that corresponds to the North West point of the area to be displayed in the Map control.
<South East position>: geoPosition variable
Name of the geoPosition variable that corresponds to the South East point of the area to be displayed in the Map control.
<Animation>: Optional boolean
- True (default value) if the area is to be displayed with an animation,
- False otherwise.
<WLanguage procedure>: Optional procedure name
Name of the WLanguage procedure ("callback") called at the end of the animation. This procedure has the following format:
where <Displayed area> is a boolean:
PROCEDURE <Procedure name> (<Displayed area>)
If <Animation> is set to False, the procedure is not called.

"Whenever changing the position" Map control event
- If the Map control moves to the specified area with an animation, the event "Whenever changing the position" will be run at the end of the animation..
- If the user cancels the positioning on the Map control before the end of the animation, the event "Whenever changing the position" will not be run.
- The zoom level of the Map control can be set to change automatically when the position changes.
- To center a map on a given position without animations, you can directly assign a geoPosition variable to the Value property of the Map control.
p1 is geoPosition
p1.Latitude = 3
p1.Longitude = 3
MAP_MyMap.Value = p1
