Are there any tool or toolbar for draw polygon or polyline features or graphics in QML API ?
No, there is no sketching tool at this point with the QML API. I recommend you checkout some of the samples in the QML sample app. Specifically, many of the geometry samples show how to sketch points, lines, and polygons. The "Relation online" sample is a good example of this. A sketching tool in some capacity is something that we are looking at adding in an upcoming release.
I create an example like "Realation online " is good example but I want to add also NavigatonToolbar in same map but I can't seen that Navigation toolbar.
We have a navigation toolbar in the toolkit that comes with the SDK. Checkout the "Navigation toolbar" sample under the toolkit section of the sample app. You might also find the "Navigation actions" sample under the Map category useful. Keep in mind that in QML, elements are drawn in the order they are declared, so make sure to add the navigation toolbar near the end of your page, so that it draws on top of the map. Also, the navigation toolbar binds to the map, so it must be a child of the map (i.e. declared inside of the map component.
Hope that helps.
