I'm currently using CesiumViewerWidget to draw shapes and allow them to be selected. At times, a large number of shapes (dynamicObjects) are present on the display and I would like to allow the user to leftClick and drag around the perimeter of an area and select all the dynamicObjects within the drawn area. Has anyone done something similar? Looking at the CesiumViewerWidget it looks like I could define a function for onLeftDrag to maybe fulfill this function, but I'm wondering if that is the best approach?
Thanks for any help you may suggest.
