Virtual Developer Workshop: Containerized Development with Docker
I needed a round slider control to let my users enter an angle. I thought this could be useful to others, so I wrote a general class for it using some of the functions from Chris Maunder's CRoundButton class.
To use, simply add a slider to your dialog. Enlarge it until it covers an approximately square area.
In OnInitDialog() you would call SetRange(), SetPos(), etc. to customize the look and feel of the round slider control.
