The imspinner library provides spinner widgets for dear imgui, like these:

Enabling the module
To enable the spinners module, update your uvproj.yaml so that the spinners key under enabled-modules is set to true like this:
name: "MyProject"
version: "1.0.0.0"
engine-version: "1.0.0.0"
enabled-modules:
spinners: true
Then, regenerate the modules cache by running the following command:
user $ ./UVKBuildTool --generate <project directory>
After that, refresh your CMake project with cmake ..!
Next, in your source file, include the Modules.hpp like this:
#include <Modules/Modules.hpp>
Event safety
The entire module is flagged as event safe at All ready.
Testing out the module
In one of your widgets, add the following code to your tick function:
ImSpinner::demoSpinners()
This will display all the available spinners, like the image at the start of the page.
