• Drop PIN for mapView

  I have this mapview

  my function

  function businessdetail(response){
  
          console.log("Response: "+response)
          var json = JSON.parse(response)
  
          map.longitude = json.longitude
          map.latitude = json.latitude
  
          }
  

  and that's my mapview

  MapView {
                              id: map

  I just want to have a PIN which exactly it fell from my latitude longtitude

  and if I click the mapview will be a road marker that leave from my site, like this

  

  a better way to do this?

  and please share some codes

  Thank you

• Add pin in a MapView

  I have a plan and an actonitem let a PIN on the map. If it is possible to put the PIN when the mapview appear in the page without using the actionitem?

  It is of the workaround that I found, I think that this is not the best method, but for my case, it's ok

  MapView {
                  id: mapview

• How to get the legend of bubble label text in MapView when we type?

  I added pins on MapView. Each pin card have a place name. Only touch the spindle, one sees a bubble. In this bubble, place name is provided. We provide the following C++ code name:

  NewDrop geolocation * = new GeoLocation();

  newDrop-> setName ("India");

  I want this place name, when I click on the legend label.

  Can someone help?

  Thanks corine.

  I tried the method you suggested.

  But I got a simple solution for this case. I added the following code in C++:

  NewDrop geolocation * = new GeoLocation();

  QString pinId = 'India ';

  newDrop-> setId (pinId);

  And in QML, I used 'focusedId', for that the bubble tapped s ID. This works.

• MapView does not show pines

• MapView problems after 2.0 update Momentics

  Hello, I am working on a prototype for an idea of the app I have and need to plan very much in the way that Foursquare manages the views of map locations. I've been led to believe that the native integration of cards required coding very little and nothing more than a few lines of code. I studied the demo mapview up and down for hours and I can't figure out what I did wrong. Here's the Basic code.

  import bb.cascades 1.2
  import bb.cascades.maps 1.0
  
  Page {
      Container {
          //Todo: fill me with QML
          Label {
              // Localized text with the dynamic translation and locale updates support
              text: qsTr("Hello World") + Retranslate.onLocaleOrLanguageChanged
              textStyle.base: SystemDefaults.TextStyles.BigText
          }
          MapView {
              id: mapview
              objectName: "mapView"
              altitude: 3000
              latitude: 43.449488

              preferredHeight: Infinity
              preferredWidth: Infinity
  
          }
      }
  }

• Draw the circle on MapView

  Hi all.

  I am quite new to the development of the Cascades.

  I would like to know if it is possible to trace a circle on a plan, given a Point and a RADIUS.

  I searched a bit on the doc, but I not only found ways to draw polygons from a set of coordinates.

  IIRC the fact maps app exactly that, show GPS accuracy of the signal (IE put a circle around you on the map to show the accuracy of the coordinates).

  Thank you very much, greetings

  Thanks BBSJdev, but I need an overlay following cards (and with a dynamic dimension) and not static.

  In any case, I found a nice way to draw a circle-layer on the mapview. Here is the code:

  It is an improved version of the solution that someone else posted on this forum some time ago (which did not perfectly, as she draws an elypse and not a circle). I can't find this post now, in any case I would like to thank the user who wrote this snippet.

  Here is the code:

  void ApplicationUI::drawCircle(double lon, double lat, double radius) {    MapView *mv = root->findChild("mapView");    DataProvider *dp = mv->mapData()->defaultProvider();
  
      // convert radius meters to latitude width    double latr = radius / 111412.84; // this is the number of meters per degree
  
      // with longitude it's a bit more complicated, since a degree of longitude 's length    // is not constant (unfortunately the earth is not flat)    int a = 6371000; // earth radius in meters    double rad_lat = 0.0174532925 * lat; // convert latitude from degrees to radiants    double _lr = ((M_PI / 180) * a * cosf(rad_lat)); // length of a degree of longitude in meters    double lonr = radius / _lr;    qDebug() << "lonr = " << lonr << " ; _lr = " << _lr << " ; latr = " << latr << " ; lat = " << lat;
  
      GeoPolygon* result = new GeoPolygon;    Polyline line;    const int numOfSeg = 36;    for ( int i = 0; i < numOfSeg; i++ ) {        double theta = 2.0f * 3.1415926f * float( i ) / float( numOfSeg );        double x = lonr * cosf( theta );        double y = latr * sinf( theta );        line.append( Coordinate( y + lat, x + lon ) );    }
  
      result->setOuterBoundary( line );    result->setId("id-circle");    mv->mapData()->defaultProvider()->add(result);
  
  }
  

• How to receive events touch of legend in mapview bubble?

  Hello developers,
  I have been woking on a map-based application. I want to see the PIN to some place on click and click a pin it there otherwise pop up on available in OS bb10 and can also add our user interface customized for the legend label. I saw an example of custom mapview http://blackberry.github.io/Cascades-Samples/custommapview.html in which they created a container separated and shown that the container during the click on pin.but that the container is not ' receive events.so touch how should I get the Touch touch events? pls help developer friends...

  Thank you

  I just tested and the onTouch Manager works perfectly.

  I added the following code in the main container of the bubble component to change the color of the label (you will need to add the > string in the Label component to test).

      onTouch: {
          label.textStyle.color = Color.Red;
      }

• Marker icon update mapview

  Hey people.

  I got a plan where I add geolocation with the marker icon.

  I want to update this marker of the icon with another icon, but the accident during the click on the marker popup after update.

  Update: I remove the geolocation of the dataprovider, I change icon, finally I add geolocation to dataprovider.

  If I don't remove/add geolocation of dataprovider, mapview is not update the marker icon.

  Thank you.

  OK, I already solve it.

  I don't have removal/addition of marker for the data provider. Just add for update.

• MapView onMapLongPressed (coordinates) bug?

  Hi, I'm not sure if I'm doing something wrong or is a bug in MapView class but I am not able to retrieve information about the coordinates on a long support class MapView.

  https://developer.BlackBerry.com/native/reference/Cascades/bb__cascades__maps__mapview.html#function...

  Acoording to the documentation, the signal of onMapLongPressed returns an object to coordinates (geo/Point class) that contains details about the location where the user long pressed.

  The returned object is undefined.

  Help, please!

  Hi @xapel,

  I could not extract data from GeoPoint via QML. I had to pass the returned object (const bb:latform::geo:anointed & coordinated) of C++ and extract and then send it to QML for use.

  I hope this helps.

• MapView navigation?

  Hello

  I created a MapView (bb::cascades:maps:MapView) and added a geolocation (bb: platform::geo:GeoLocation) which shows a marker on the map.

  I added a name and a description to my place:

  location-> setName ("Point of interest");

  location-> setDescription ("this point is interesting");

  Then when I click on the marker of the small bubble will appear showing me 3 things:

  -Name of geolocation. 'Point of interest '.

  -Description of geolocation. "This is interesting".

  -A top arrow button.

  The arrow on the button is usually associated with the ability to navigate to the marker in question. How to capture a button from this button? And more important still, how do I start navigation when the button is pressed?

  Thank you!

  For Navigation, you will need to use the RouteInvoker

  To use it, you'll need this in your main.cpp:

  #include 
  
  qmlRegisterType("bb.platform", 1, 0, "RouteMapInvoker");
          bb::data::DataSource::registerQmlTypes();
  

  ^ put this right under this code in your main.cpp:

  Q_DECL_EXPORT int main(int argc, char **argv)
  {
  

  In addition to setting this in your qml:

  RouteMapInvoker {
  
              id: routeInvoker
  
          }
  

  And then onClicked or notecard use this:

  onTriggered: {
                  routeInvoker.endLatitude = listItemLat.text <<

• MapView rendering time at the start of the application

  There is a lag of a few seconds of starting the application until the card is returned. I want to show an ActivityIndicator while the map is rendered. Is there a way to know when is the plan released?
  I checked RenderEngine class a signal called renderCompleted who can help me, but I can access the current MapView RenderEngine...

  Kind regards.

  Currently, the answer is no. But we certainly hope that providing signals when the card is rendered/rendering.

  Can you provide specific details on what reports you want to see? For example all the tiles have been made, card is functional, etc... ?
