The ArcGIS Maps SDK for Qt has a Toolkit that provides ready made components to complement mapping and GIS applications.
The toolkit is open source and you are encouraged to modify the tools and add your own.
For overview of this toolkit and how to use it, see the Toolkit README on GitHub.
This is the API reference for the toolkit components.
UI tools
UI tools are ready-to-use components that can be added to your app to enable common-place ArcGIS workflows. For example, North Arrow, Time Slider, and Popups are all ubiquitous with ArcGIS. These components are default implementations that leverage capabilities exposed by the ArcGIS Maps API. The tools have been architected to utilize MVC design principles, so for each view, there is an associated controller. These views and controllers can be further modified or customized to suit your needs. For details on integrating the UI tools into your project, see the Qt Quick UI Components README on GitHub, or the Qt Widgets UI Components README on GitHub.
The following list contains the available tools for each app development paradigm:
