llsliderThis slider replaces the common control track bar. It offers scrollwheel support and colour gradient as background (or just a colour).

  • Not based on common controls
  • Specify two colours for the background
  • Ability to draw a gradient or one characteristic background colour
  • CenterColourPosition: Specify a position that determines inversion of gradient (like on the image)
  • Mousewheel support
  • draw custom numbers
  • draw custom ticks

This slider can also be used in my TDateTimeCombo, if you enable the compiler directive.
