In 10.2.6 of Arc GIS Runtime SDK for Qt, we used to create a graphic and on adding this to a Graphic Layer we get 'id'. With this 'id' we can access that graphic for modification or updation on GraphicLayer. How to achieve this functionality in ArcGIS Runtime SDK for Qt 100.1 with out using identifyGraphicsOverlay method (this function is used during mouse click)? One way to acheive this is like, get all graphics on GraphicsOverlay and iterate to get required graphic by searching with required atttribute. But this may take time for traversal as this is regular operation. For example we may want to update a graphic on everytime we receive gps location.
