Handling a Map control by programming

Overview

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

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

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 around the equator, with the lowest zoom level. 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"Store the last displayed position" 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:

the function MapDisplayPosition: 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 géoPosition
MapDisplayPosition(MAP_Position, MyPosition)

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

// Centers the map displayed by the "MAP_Position" control on a monument
// from its name
MapDisplayPosition(MAP_Position, "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)

Versions 20 and later

Several settings are available for the Map control found in WEBDEV. WEBDEV gives you the ability to use additional parameters, available in the Google API for map management.

To do so, two functions are available:

MapConfigureGglAPI (that can be used in server code) allows you to specify the additional parameters that will be managed on the Map control. These parameters are global to the project.
MapGetJSObject (that can be used in browser code) allows you to retrieve the map and its options in a dynamic object in order to handle the control in Javascript code.

Example:

Declaring the libraries to load in server code:

// Server code
MapConfigureGglAPI("libraries=geometry,places","language=fr")
Retrieving the dynamic object in browser code:

// Browser code
MyMap is object dynamic
MyMap = MapGetJSObject(MAP_Browser)
// Call to the Javascript function
FindAddress()
Javascript function used to handle the Map control:

// Javascript function that is using the dynamic object
function FindAddress()
{
var infowindow;
// Rome: 41.873144, 12.480391
var pyrmont = new google.maps.LatLng(41.873144, 12.480391);
var request = {
location: pyrmont,
radius: 500,
types: ['store']
};
infowindow = new google.maps.InfoWindow();
var service = new google.maps.places.PlacesService(MyMap);
service.nearbySearch(request, ReturnAddress_WB);
}
