<Map>.InfoXY (Function)

In french: <Carte>.InfoXY

Returns the geographical position (latitude and longitude) corresponding to a point in a Map control.

Note: This function is available in the Android emulator and in the Android simulator.

Example

// Ajout d'un marqueur à l'emplacement du clic dans un champ Carte 
// (code à placer dans le code de clic du champ)
MaPosition is geoPosition
MaPosition = CARTE_Position.InfoXY(MouseXPos(), MouseYPos())
IF ErrorOccurred = False THEN
	MonMarqueur is Marker
	MonMarqueur.Position = MaPosition
	CARTE_Position.AjouteMarqueur(MonMarqueur)
END

Syntax

<Result> = <Map control>.InfoXY(<X> , <Y>)

<Result>: geoPosition variable

geoPosition variable corresponding to the geographical position of the point on the map.
In an error occurs, the ErrorOccurred variable is set to True and ErrorInfo returns the details of the error.

<Map control>: Control name

Name of the Map control to 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 searched 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 searched 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):
- use the MouseXPos and MouseYPos functions.
- use the GesturePosX and GesturePosY functions.
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.
