MapInfoXY (Function) In french: CarteInfoXY Returns the geographical position (latitude and longitude) corresponding to a point in a Map control.
// Add a marker at the click location in a Map control
// (code to include in the click code of control)
MyLocation is geoPosition
MyPosition = MapInfoXY(MAP_Position, MouseXPos(), MouseYPos())
IF ErrorOccurred = False THEN
MyMarker is Marker
MyMarker.Position = MyLocation
MapAddMarker(MAP_Position, MyMarker)
END
Syntax
<Result> = MapInfoXY(<Map control> , <X> , <Y>)
<Result>: geoPosition variable geoPosition variable corresponding to the geographical position of the point on the map.
<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 event belongs will be used. <X>: Integer X-coordinate (in pixels) of point to study. This coordinate is relative to the upper-left corner of the control. If this coordinate is negative, the position will be sought for a point that is not displayed on the map. <Y>: Integer Y-coordinate (in pixels) of point to study. This coordinate is relative to the upper-left corner of the control. If this coordinate is negative, the position will be sought for a point that is not displayed on the map. Remarks - To retrieve the coordinates of a point in the Map control in which an event was run (e.g. click):
- The calculation of position takes into account the zoom level in the Map control during the call to the function. The higher the zoom level is, the more precise the position will be.
