SetFontStyle(FontStyle)

設定 FormattedText 物件中整個字元集的字型樣式。

public:
 void SetFontStyle(System::Windows::FontStyle style);

public void SetFontStyle (System.Windows.FontStyle style);

member this.SetFontStyle : System.Windows.FontStyle -> unit

Public Sub SetFontStyle (style As FontStyle)

參數

style

FontStyle

用於文字格式設定的 FontStyle 值。

備註

FontStyle 支援型別轉換行為，讓 類別的 FontStyles 靜態值可用來初始化 FontStyle 和填滿類型 FontStyle 的參數。

這個方法會設定整個文字字串的字型樣式。 若要設定文字字串子集的字型樣式，請使用 SetFontStyle(FontStyle, Int32, Int32) 方法。

SetFontStyle(FontStyle, Int32, Int32)

設定 FormattedText 物件中所指定字元子集的字型樣式。

public:
 void SetFontStyle(System::Windows::FontStyle style, int startIndex, int count);

public void SetFontStyle (System.Windows.FontStyle style, int startIndex, int count);

member this.SetFontStyle : System.Windows.FontStyle * int * int -> unit

Public Sub SetFontStyle (style As FontStyle, startIndex As Integer, count As Integer)

參數

style

FontStyle

用於文字格式設定的 FontStyle 值。

startIndex

Int32

要套用字型樣式之初始字元的起始索引。

count

Int32

要套用字型樣式的字元數目。

範例

下列範例會建立 物件，然後將數種 FormattedText 格式樣式套用至文字，包括 SetFontStyle 。

protected override void OnRender(DrawingContext drawingContext)
{
    string testString = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor";

    // Create the initial formatted text string.
    FormattedText formattedText = new FormattedText(
        testString,
        CultureInfo.GetCultureInfo("en-us"),
        FlowDirection.LeftToRight,
        new Typeface("Verdana"),
        32,
        Brushes.Black);

    // Set a maximum width and height. If the text overflows these values, an ellipsis "..." appears.
    formattedText.MaxTextWidth = 300;
    formattedText.MaxTextHeight = 240;

    // Use a larger font size beginning at the first (zero-based) character and continuing for 5 characters.
    // The font size is calculated in terms of points -- not as device-independent pixels.
    formattedText.SetFontSize(36 * (96.0 / 72.0), 0, 5);

    // Use a Bold font weight beginning at the 6th character and continuing for 11 characters.
    formattedText.SetFontWeight(FontWeights.Bold, 6, 11);

    // Use a linear gradient brush beginning at the 6th character and continuing for 11 characters.
    formattedText.SetForegroundBrush(
                            new LinearGradientBrush(
                            Colors.Orange,
                            Colors.Teal,
                            90.0),
                            6, 11);

    // Use an Italic font style beginning at the 28th character and continuing for 28 characters.
    formattedText.SetFontStyle(FontStyles.Italic, 28, 28);

    // Draw the formatted text string to the DrawingContext of the control.
    drawingContext.DrawText(formattedText, new Point(10, 0));
}

Protected Overrides Sub OnRender(ByVal drawingContext As DrawingContext)
    Dim testString As String = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor"

    ' Create the initial formatted text string.
    Dim formattedText As New FormattedText(testString, CultureInfo.GetCultureInfo("en-us"), FlowDirection.LeftToRight, New Typeface("Verdana"), 32, Brushes.Black)

    ' Set a maximum width and height. If the text overflows these values, an ellipsis "..." appears.
    formattedText.MaxTextWidth = 300
    formattedText.MaxTextHeight = 240

    ' Use a larger font size beginning at the first (zero-based) character and continuing for 5 characters.
    ' The font size is calculated in terms of points -- not as device-independent pixels.
    formattedText.SetFontSize(36 * (96.0 / 72.0), 0, 5)

    ' Use a Bold font weight beginning at the 6th character and continuing for 11 characters.
    formattedText.SetFontWeight(FontWeights.Bold, 6, 11)

    ' Use a linear gradient brush beginning at the 6th character and continuing for 11 characters.
    formattedText.SetForegroundBrush(New LinearGradientBrush(Colors.Orange, Colors.Teal, 90.0), 6, 11)

    ' Use an Italic font style beginning at the 28th character and continuing for 28 characters.
    formattedText.SetFontStyle(FontStyles.Italic, 28, 28)

    ' Draw the formatted text string to the DrawingContext of the control.
    drawingContext.DrawText(formattedText, New Point(10, 0))
End Sub

備註

FontStyle 支援型別轉換行為，讓 類別的 FontStyles 靜態值可用來初始化 FontStyle 和填滿類型 FontStyle 的參數。

若要設定整個文字字串的字型樣式，請使用 SetFontStyle(FontStyle) 方法。
