Hello everyone. I've built and published a geoprocessing tool that lets an ArcMap user click somewhere near a line (route) and it generates a shapefile with calculated station & offset values. This is my first real foray into model builder and designing a GP tool to work with a custom in-panel WAB widget. Seems like I'm taking on a lot at once. So where does one start? I've looked at example custom widgets but they're either too complicated or they don't shake hands with a GP tool and display the calculated results. I'd like to create a very simple custom widget that prompts the user for a point (click on the WAB map) and it displays the station & offset information from the shapefile generated by the geoprocessing service.
I've gone through the instructions here: Create a custom in-panel widget—Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers and checked out some of the custom widgets here: Web AppBuilder Widget Search
Is there a very simple custom widget out there that can interact with a geoprocessing service?
