En Silverlight5 obtenir les propriétés à utiliser pour mettre à jour une barre d'outils:
private void rtb_SelectionChanged(object sender, RoutedEventArgs e)
{
TextSelection ts = rtb.Selection;
object property;
property = ts.GetPropertyValue(Run.FontWeightProperty);
System.Windows.FontWeight fontWeight = property is System.Windows.FontWeight ? (FontWeight)property : FontWeights.Normal;
property = ts.GetPropertyValue(Run.FontStyleProperty);
System.Windows.FontStyle fontStyle = property is System.Windows.FontStyle ? (FontStyle)property : FontStyles.Normal;
TextDecorationCollection textDecorations = ts.GetPropertyValue(Run.TextDecorationsProperty) as TextDecorationCollection;
bool isUnderlined = textDecorations != null;
double? fontSize = ts.GetPropertyValue(Run.FontSizeProperty) as double?;
SolidColorBrush foreground = ts.GetPropertyValue(Run.ForegroundProperty) as SolidColorBrush;
Color foregroundColor = foreground != null ? foreground.Color : Colors.Black;
System.Diagnostics.Debug.WriteLine("fontweight:{0}, fontStyle:{1}, Underline:{2}, size:{3}, color:{4}",
fontWeight,
fontStyle,
isUnderlined,
fontSize,
foregroundColor);
if (fontSize.HasValue)
SetToolbarFontSize(fontSize.Value);
SetToolbarFontColor(foregroundColor);
}
Merci Matt. Exactement ce que je cherchais. –
