Hello @SEMad ,
TouchGFX doesn't currently support this kind of widget, unfortunately.
So, you will have to create it yourself.
You can for example start from a Circle widget, adjust he Start & End Angle parameters, modify the code to detect the user finger location on the circle, in order to move the indicator accordingly to that. There is the documentation of this widget.
Otherwise, you can take a look to the Custom widget documentation, if you want to create a new component from scratch.
Hope that this helped,
