Detailed Description

a check box control with a title and 3 states

A checkbox control with a title and 3 states : checked, half checked, not checked

  • if value is < 0.5 the checkbox is not checked
  • if value is 0.5 the checkbox is half checked
  • if value is > 0.5 the checkbox is checked

the user can only switch between checked and not checked state.

If the bitmap is set, the bitmap must contain 6 states of the checkbox in the following order:

  • not checked
  • half checked
  • checked
  • not checked hilighted
  • half checked hilighted
  • checked hilighted
