Boolean Converters

These converters map bool values into colors, visibility states, or arbitrary values for UI binding scenarios.

BoolToColorConverter

• Purpose: Converts a bool into a SolidColorBrush (default: Green for true, Red for false)
• Constructor Parameters:
  • trueColor: Color to use when value is true (default: Colors.Green)
  • falseColor: Color to use when value is false (default: Colors.Red)

Basic Usage Example

<TextBlock Text="Online Status"
           Foreground="{Binding IsOnline, Converter={StaticResource BoolToColorConverter}}" />

Custom Colors Example

<converters:BoolToColorConverter x:Key="CustomBoolToColor"
                                 TrueColor="Blue"
                                 FalseColor="Gray" />

BoolToStatusColorConverter

• Namespace: GenHub.Infrastructure.Converters
• Purpose: Converts a bool into a status hex color string (#4CAF50 for true, #F44336 for false)
• Return Type: string (hex color code)

Status Color Usage

<Border Background="{Binding IsConnected, Converter={StaticResource BoolToStatusColorConverter}}" />

---

BoolToValueConverter

• Namespace: GenHub.Infrastructure.Converters
• Purpose: Converts a bool into custom values specified by TrueValue and FalseValue properties
• Properties:
  • TrueValue: Object to return when input is true
  • FalseValue: Object to return when input is false

Value Converter Usage

<converters:BoolToValueConverter x:Key="BoolToTextConverter"
                                 TrueValue="Enabled"
                                 FalseValue="Disabled" />
<TextBlock Text="{Binding IsEnabled, Converter={StaticResource BoolToTextConverter}}" />

Property Configuration

<converters:BoolToValueConverter x:Key="BoolToVisibilityConverter"
                                 TrueValue="Visible"
                                 FalseValue="Collapsed" />
<Button IsVisible="{Binding CanSave, Converter={StaticResource BoolToVisibilityConverter}}" />

---

BoolToVisibilityConverter

• Purpose: Converts a bool into "Visible" or "Collapsed" string for Avalonia visibility binding
• Return Type: string ("Visible" or "Collapsed")

Visibility Usage

<Button Content="Save"
        IsVisible="{Binding CanSave, Converter={StaticResource BoolToVisibilityConverter}}" />

---

InvertedBoolToVisibilityConverter

• Purpose: Inverse of BoolToVisibilityConverter — true → "Collapsed", false → "Visible"
• Return Type: string ("Visible" or "Collapsed")

Inverted Visibility Usage

<TextBlock Text="No results found"
           IsVisible="{Binding HasResults, Converter={StaticResource InvertedBoolToVisibilityConverter}}" />

Real Usage Patterns

<!-- Status color indicators -->
<Border Background="{Binding IsConnected, Converter={StaticResource BoolToStatusColorConverter}}" />

<!-- Conditional visibility for buttons -->
<Button Content="Launch Game"
        IsVisible="{Binding CanLaunch, Converter={StaticResource BoolToVisibilityConverter}}" />

<!-- Inverted visibility for error messages -->
<TextBlock Text="Game not found"
           IsVisible="{Binding GameExists, Converter={StaticResource InvertedBoolToVisibilityConverter}}" />

<!-- Custom text values -->
<TextBlock Text="{Binding IsInstalled, Converter={StaticResource BoolToValueConverter},
                          ConverterParameter='Installed;Not Installed'}" />

Real Usage in Game Profile Scenarios

<!-- Profile validation status -->
<Border Background="{Binding IsValid, Converter={StaticResource BoolToStatusColorConverter}}"
        CornerRadius="4" Padding="8">
    <TextBlock Text="{Binding IsValid, Converter={StaticResource BoolToValueConverter},
                              ConverterParameter='Valid Profile;Invalid Profile'}" />
</Border>

<!-- Launch button visibility -->
<Button Content="Launch"
        IsVisible="{Binding CanLaunch, Converter={StaticResource BoolToVisibilityConverter}}" />

<!-- Error message visibility -->
<TextBlock Text="Please select a game version"
           IsVisible="{Binding HasSelectedVersion, Converter={StaticResource InvertedBoolToVisibilityConverter}}" />

Real Usage in GameProfileLauncherView.axaml

<!-- Edit mode background toggle using BoolToColorConverter with custom colors -->
<Border Background="{Binding IsEditMode, Converter={StaticResource EditModeToggleBackgroundConverter}, Mode=OneWay}" />

Where EditModeToggleBackgroundConverter is defined as:

<conv:BoolToColorConverter x:Key="EditModeToggleBackgroundConverter" TrueColor="#1E88E5" FalseColor="#333333" />

This demonstrates how BoolToColorConverter can be customized with specific colors for different UI contexts.
