notes about props

  • value prop - this component uses it's own state to hold value if value is not given as a prop
  • style props - this component has a default style and the styles props are to override the default style or add more fields
  • totalWidth prop - this prop is for the entire component width, and all other sizes are derived from it , unless given other size props
  • initValue prop - if using value prop, this is not needed and the initial value can be given by the value prop
  • validateOnBlur - added on version 1.3.2, if set to false the text input will validate while typing, not recommended, so just keep it true unless there is a good reason not to use the default functionallity
  • reachMaxIncIconStyle - added on version 1.4.0, used to set style to the increment button icon in case maxValue is reached - optional
  • reachMaxDecIconStyle - added on version 1.4.0, used to set style to the decrement button icon in case maxValue is reached - optional
  • reachMinIncIconStyle - added on version 1.4.0, used to set style to the increment button icon in case minValue is reached - optional
  • reachMinDecIconStyle - added on version 1.4.0, used to set style to the decrement button icon in case minValue is reached - optional
