Handling a Map control by programming (prefixed syntax)

Overview

WINDEV, WEBDEV and WINDEV Mobile allow you to handle a Map control by programming. To do so, use the variable of the Map control in the code.

The variable of the Map control corresponds to the name of the Map control.

This help page explains how to handle a Map control by programming.

Remark: Several WLanguage functions are specific to the management of Map controls. See Map control management functions for more details.

Versions 20 and later

The Map control is now available for the WINDEV applications in Windows.

The Map control is now available for the WEBDEV sites in Windows and Linux.

New in version 20

The Map control is now available for the WINDEV applications in Windows.

The Map control is now available for the WEBDEV sites in Windows and Linux.

The Map control is now available for the WINDEV applications in Windows.

The Map control is now available for the WEBDEV sites in Windows and Linux.

Versions 21 and later

The Map control is now available in Universal Windows 10 App mode.

New in version 21

The Map control is now available in Universal Windows 10 App mode.

Initializing a map

Displaying a map

When the window containing a Map control is opened, a map of the world is automatically displayed: the map is centered on Europe, with minimum zoom level.

You have the ability to display the last position stored: simply select the option"Remember last position displayed" in the "General" tab of the Map control description window. In this case, the last position is displayed with the same zoom level.

To display a map corresponding to a specific location, use:

<Map>.DisplayPosition: This function can be used with a specific position (geoPosition variable), or on a town or a monument.
For example:

// Centers the map displayed by the "MAP_Position" control
// on a geographical location
MyPosition is geoPosition
MAP_Position.DisplayPosition(MyPosition)

// Centers the map displayed by the "MAP_Position" control on a city
// from its name
MAP_Position.DisplayPosition("Montpellier, France")

// Centers the map displayed by the "MAP_Position" control on a monument
// from its name
MAP_Position.DisplayPosition("Eiffel Tower")
a direct assign command with a specific position. In this case, the position is displayed without any animation.
Example:

// Centers the map displayed by the "MAP_Position" control
// on a geographical location
MyPosition is geoPosition
MAP_Position = MyPosition

Managing advanced parameters (WEBDEV)

The following functions can be used with the Map controls

The WLanguage functions that can be used with the Map controls can be classified in several categories:

The functions used to manage the positions on the map:


<Map>.DisplayPosition	Centers the map displayed in a Map control on a geographical position or on a specific location.
<Map>.GetPosition	Returns the geographical position of the point located in the center of the map currently displayed in a Map control.
<Map>.InfoPosition	Returns the coordinates (in pixels) of the point corresponding to a geographical position (latitude and longitude).
<Map>.InfoXY	Returns the geographical position (latitude and longitude) corresponding to a point in a Map control.

The functions used to follow the movements of the device:
<Map>.EndOfMove Stops following the device movement in a Map control.
<Map>.FollowMovement Displays the current device position in a Map control and updates this position during its move.

The functions used to manage the markers on the map. These functions use the Marker variables to define the characteristics of these markers.


<Map>.AddMarker	Adds a new marker onto a map displayed in a Map control.
<Map>.DeleteAll	Deletes all markers from a Map control.
<Map>.DeleteMarker	Deletes a marker from a map displayed by a Map control
<Map>.ModifyMarker	Modifies a marker displayed in a Map control.

The functions used to manage the itineraries on the map.


Versions 18 and later <Map>.AddItinerary New in version 18 <Map>.AddItinerary <Map>.AddItinerary	Adds an itinerary onto a Map control.
Versions 18 and later <Map>.DeleteItinerary New in version 18 <Map>.DeleteItinerary <Map>.DeleteItinerary	Deletes an itinerary from a Map control.
