Converters

Purpose

This module provides WPF value converters for the GroupChannelList UI component. It exists to transform data values into visual representations in XAML bindings, specifically converting boolean values to width measurements and background brush colors for sensor ID display elements.

Public Interface

• BooleanToWidthConverter class (public) - Implements IValueConverter. Converts boolean values to width values for UI element sizing.

  • object Convert(object value, Type targetType, object parameter, CultureInfo culture) - Returns width (parsed from parameter) if value is true, returns 0 if value is false, returns 0 if value is null. If parameter parsing fails, returns double.NaN.
  • object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) - Throws NotImplementedException.

• SensorIdBackgroundConverter class (public) - Implements IValueConverter. Converts boolean values to background brush colors.

  • object Convert(object value, Type targetType, object parameter, CultureInfo culture) - Returns a light green brush (#FFE3FBE1) if value is true, returns Brushes.Transparent if value is false or null. Catches and traces exceptions.
  • object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) - Throws NotImplementedException.

Invariants

• ConvertBack is not implemented on either converter; these are one-way converters only.
• SensorIdBackgroundConverter.SensorIdBrush is a static field that is frozen before return to make it thread-safe and non-modifiable.

Dependencies

• Depends on: System.Windows.Data.IValueConverter, System.Windows.Media.SolidColorBrush, System.Windows.Media.Color, System.Windows.Media.Brushes, System.Globalization.CultureInfo, System.Diagnostics.Trace.
• Depended on by: XAML views in the `GroupChannelList
