# WPF RTL (Right-to-Left) Support

Implement bidirectional text and mirrored layouts for RTL languages.

## 1. RTL Languages

| Language | Culture Code | Direction |
|----------|-------------|-----------|
| Arabic | ar-SA, ar-EG | RTL |
| Hebrew | he-IL | RTL |
| Persian (Farsi) | fa-IR | RTL |
| Urdu | ur-PK | RTL |

## 2. Setting FlowDirection

### 2.1 Window Level

```xml
<!-- Left-to-Right (default) -->
<Window FlowDirection="LeftToRight"
        Title="My Application">

<!-- Right-to-Left -->
<Window FlowDirection="RightToLeft"
        Title="التطبيق">
```

### 2.2 Element Level

```xml
<Window FlowDirection="RightToLeft">
    <StackPanel>
        <!-- Inherits RTL from parent -->
        <TextBlock Text="مرحبا بالعالم"/>

        <!-- Override to LTR for specific content -->
        <TextBlock FlowDirection="LeftToRight"
                   Text="user@example.com"/>
    </StackPanel>
</Window>
```

### 2.3 Resource-Based

```xml
<Window FlowDirection="{DynamicResource AppFlowDirection}">

<!-- In ResourceDictionary -->
<FlowDirection x:Key="AppFlowDirection">RightToLeft</FlowDirection>
```

## 3. Dynamic FlowDirection

### 3.1 Based on Culture

```csharp
public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        SetFlowDirection();
    }

    private void SetFlowDirection()
    {
        var culture = Thread.CurrentThread.CurrentUICulture;
        FlowDirection = culture.TextInfo.IsRightToLeft
            ? FlowDirection.RightToLeft
            : FlowDirection.LeftToRight;
    }
}
```

### 3.2 Language Switching

```csharp
public void SwitchLanguage(string cultureName)
{
    var culture = new CultureInfo(cultureName);

    Thread.CurrentThread.CurrentCulture = culture;
    Thread.CurrentThread.CurrentUICulture = culture;

    // Update FlowDirection
    Application.Current.MainWindow.FlowDirection =
        culture.TextInfo.IsRightToLeft
            ? FlowDirection.RightToLeft
            : FlowDire
