How could I rotate the Map of Qt5.9 beta?

tham

Qt5.9 add a new property tilt on qml Map, but I do not find any rotation property or qml type to rotate the map, do anyone know how to rotate it?Thanks

tham

I found the answer, it is based on bearing value of Map, tilt and bearing works for osm and here plugin, thanks for vincent from Qt Mob.

Hi,

Will you give me some detail, please? I am using HERE map plugin.

tham

@aktay Sure

Map{

tilt: 45 //tilt 45 degree
bearing: 45 //rotate 45 degree

}

It is so easy. QtLocation module works well for online routing, but to create a serious navigation app, we need ability of offline routing(unless you are ok with osm), without it, transaction/services will be used up in no time. Esri runtime SDK provide offline routing and other interesting functions, but

1 : the extra api provided by that sdk do not conform to Qt api, which means your apps will be binded by esri
2 : their services are quite expensive

Thank you for your answer. But I am getting the error. Do you have any idea why?

  Map{
        id: map
        anchors.fill: parent
        plugin:mapPlugin
        center: QtPositioning.coordinate(latitude, longitude)
        zoomLevel: 18
       copyrightsVisible: false
      tilt: 45 //tilt 45 degree
      bearing: 45 //rotate 45 degree

....

The Error:

Cannot assign to non-existent property "tilt"
Cannot assign to non-existent property "bearing"

I also started to work with esri. I guess I should not use the ESRI according to what you say. What should we do for a navigation-like application? What is your suggestion?

Thanks.

You need Qt5.9 beta for these features

It depends on how much budgets you got. I would pick esri if the customers have limited budgets, try my best not to use/encapsulate the api of esri sdk, this way in the future I could replace esri api by "standard Qt"(5.10?5.11?God knows)

If the customers willing to pay the fees to develop custom plugin, I would start from study the plugin source codes of Qt and try to add offline routing function(an engineer of Google spend half a year to implement offline routing features on ios).

Dear @aktay ,
you can use rotation property in Map component instead in QT 5.8 and 5.7

@Alien

I upgraded to Qt 5.9.
I am using:

   tilt: 45 //tilt 45 degree
      bearing: 45 //rotate 45 degree

What is the method you recommend? Can you be more descriptive?

Alien

@aktay ,
Congratulation to use 5.9 that was about old release of Qt forget it ;)
