Client-Side API

  • Demo Configurator
  • The LinearGauge properties
    Width: px
    Height: px
    Value:

    The RadialGauge properties
    Width: px
    Height: px
    Value:

This demo shows the available Client-side API for the RadGauge controls. Both the Linear and Radial gauges expose several common methods:

  • get_height()
  • get_width()
  • get_value()
  • set_height()
  • set_width()
  • set_value()

The getters return numerical values and the setters check if the variable that is passed is a proper number and in the range shown in the gauge (for the value).
