  • Method Details

    • get_IsReadOnly

      boolean get_IsReadOnly()
      Indicates whether the value of a control is read-only.
      Returns:
      true if readonly

    • get_LargeChange

      double get_LargeChange()
      Specifies the value that is added to or subtracted from the IRangeValueProvider::Value property when a large change is made, such as when the PAGE DOWN key is pressed.

      The LargeChange property can support Not a Number (NaN) value. When returning a NaN value, the provider should return a quiet (non-signaling) NaN to avoid raising an exception if floating-point exceptions are turned on. The following example shows how to create a quiet NaN:

      Returns:
      the large change

    • get_Maximum

      double get_Maximum()
      Specifies the maximum range value supported by the control.

      This value should be greater than Minimum.

      Returns:
      the maximum

    • get_Minimum

      double get_Minimum()
      Specifies the minimum range value supported by the control.

      This value should be less than Maximum.

      Returns:
      the minimum

    • get_SmallChange

      double get_SmallChange()
      Specifies the value that is added to or subtracted from the IRangeValueProvider::Value property when a small change is made, such as when an arrow key is pressed.

      The SmallChange property can support Not a Number (NaN) value. When returning a NaN value, the provider should return a quiet (non-signaling) NaN to avoid raising an exception if floating-point exceptions are turned on. The following example shows how to create a quiet NaN:

      Returns:
      the small change

    • get_Value

      double get_Value()
      The value of the control.
      Returns:
      the value

    • SetValue

      void SetValue(double value)
      Sets the value of control.

      The actual value set depends on the control implementation. The control may round the requested value up or down.

      Parameters:
      value - the value
