Simple usage viewer marker

This example show how to view map with marker:

protected function createComponentNetteGMapSimpleViewer() {
    $markers = array();
    $markers[] = new \Marker("home", "description", "49.1695254488", "14.2521617334");
    
    //$netteGMapViewer->setCenterMap(new \GpsPoint(49.1695254488,14.2521617334));
    //$netteGMapViewer->setScrollWheel(true);
    //$netteGMapViewer->setZoom(12);
    $netteGMapViewer = new \NetteGMapViewer($markers);
          
    return $netteGMapViewer;
}

{control netteGMapSimpleViewer}

Usage viewer marker with polyline

This example show how to show map with marker:

protected function createComponentNetteGMapViewerPolyline() {
    $markers = array();
    $markers[] = new \Marker("home", "description", "49.1695254488", "14.2521617334");
    
    //$netteGMapViewer->setCenterMap(new \GpsPoint(49.1695254488,14.2521617334));
    //$netteGMapViewer->setScrollwheel(TRUE);
    //$netteGMapViewer->setZoom(12);
    $netteGMapViewer = new \NetteGMapViewer($markers);    
    
    //add polyline to map
    $coordinates = array(
        new \GpsPoint(49.169669, 14.252152),
        new \GpsPoint(49.169399, 14.252175),
        new \GpsPoint(49.169532, 14.251842),
        new \GpsPoint(49.169669, 14.252152)
    );
    $polyLine = new \PolyLine($coordinates);
    $netteGMapViewer->setPolyLine($polyLine);
          
    return $netteGMapViewer;
}

{control netteGMapViewerPolyline}

Usage picker in form

This example show how to set GPS position on map:

protected function createComponentGMapForm() {

    $form = new Nette\Application\UI\Form;
    
    $form->addGMap('position', 'Position:')
        ->setWidth("500")
        ->setHeight("500");
        //->showMyActualPositionButton();
        //->setScrollwheel(TRUE);
    
    $form->addSubmit('send', 'Save');
    
    $form->onSuccess[] = [$this, 'gMapFormSucceeded'];
    return $form;
}

public function gMapFormSucceeded($form) {
    $values = $form->getValues();
    
    dump($values);
    exit();
}

Set default position value for picker:

$form->setDefaults(array(
    'position' => array(
        'latitude' => "49.1695254488",
        'longitude' => "14.2521617334",
    ),
));

Latte:

{control gMapForm}

After send form:

Nette\ArrayHash #f110
    position => array (2)
        latitude => "50.0923932109" (13)
        longitude => "14.4580078125" (13)

Usage layer

This example show how to add own picture on map as a new layer:

protected function createComponentNetteGMapLayer() {
    $netteGMapViewer = new \NetteGMapLayer();
    //$netteGMapViewer->setCenterMap(new \GpsPoint("48.977153", "14.454486"));
    $netteGMapViewer->setHeight("600px");
    $netteGMapViewer->setScrollwheel(TRUE);
    $netteGMapViewer->setZoom(18);
    
    $netteGMapViewer->setLayerUrlImage("http://www.barcampjc.cz/pictures/parkoviste.jpg");
    
    $netteGMapViewer->setLayerLeftDownCorner(new \GpsPoint(48.97685376928403, 14.453693823169715));
    $netteGMapViewer->setLayerRightTopCorner(new \GpsPoint(48.97771464665134, 14.45583921230309));
    
    return $netteGMapViewer;
}

Latte:

{control netteGMapLayer}

Get coordinates from address

\GMapUtils::getCoordinatesFromAddress("Prague, Czech Republic")

return

array( "gps_lat" => 50.0755381, "gps_lon" => 14.4378005)

Get address from coordinates

\GMapUtils::getAddressFromCoordinates( 50.0755381, 14.4378005 )

return

Náměstí Míru 820/9, 120 00 Praha-Praha 2, Czech Republic

Set marker position from out script (JS)

Callback after change position marker in main.js

When you want call your code after marker position chaged, you can be inspired by this code. main.js

$( function() {
    $( 'body' ).netteGMapPicker( {
    
        //my callback marker change position
        changePositionMarker: function( results ) {    
            var district = results[4].formatted_address.split(",");
            //alert( district[0] );
            $("select#frm-addCompetitionForm-district_id option").each(function() { this.selected = ( this.text === district[0] ); });
            $("select#frm-editCompetitionForm-district_id option").each(function() { this.selected = ( this.text === district[0] ); });
            //alert('changePositionMarker');
        }
    
    } );	
} );
