回傳選項按鈕（也稱為單選按鈕）字形的像素大小。

public:
 static System::Drawing::Size GetGlyphSize(System::Drawing::Graphics ^ g, System::Windows::Forms::VisualStyles::RadioButtonState state);
public static System.Drawing.Size GetGlyphSize(System.Drawing.Graphics g, System.Windows.Forms.VisualStyles.RadioButtonState state);
static member GetGlyphSize : System.Drawing.Graphics * System.Windows.Forms.VisualStyles.RadioButtonState -> System.Drawing.Size
Public Shared Function GetGlyphSize (g As Graphics, state As RadioButtonState) As Size

參數

g
Graphics

Graphics他們用來畫選項按鈕。

state
RadioButtonState

其中一個 RadioButtonState 值是指定選項按鈕視覺狀態的。

傳回

Size

Size A 代表選項按鈕字形的大小（以像素為單位）。

範例

以下程式碼範例使用此 GetGlyphSize 方法來判定選項按鈕文字的界限。 此程式碼範例是本類別更大範例 RadioButtonRenderer 的一部分。

    // Define the text bounds so that the text rectangle
    // does not include the radio button.
public:
    property Rectangle TextRectangle
    {
        Rectangle get()
        {
            Graphics^ g = this->CreateGraphics();

            textRectangleValue.X = ClientRectangle.X +
                RadioButtonRenderer::GetGlyphSize(g,
                RadioButtonState::UncheckedNormal).Width;
            textRectangleValue.Y = ClientRectangle.Y;
            textRectangleValue.Width = ClientRectangle.Width -
                RadioButtonRenderer::GetGlyphSize(g,
                RadioButtonState::UncheckedNormal).Width;
            textRectangleValue.Height = ClientRectangle.Height;
         
            delete g;                

            return textRectangleValue;
        }
    }

// Define the text bounds so that the text rectangle 
// does not include the radio button.
public Rectangle TextRectangle
{
    get
    {
        using (Graphics g = this.CreateGraphics())
        {
            textRectangleValue.X = ClientRectangle.X +
                RadioButtonRenderer.GetGlyphSize(g,
                RadioButtonState.UncheckedNormal).Width;
            textRectangleValue.Y = ClientRectangle.Y;
            textRectangleValue.Width = ClientRectangle.Width -
                RadioButtonRenderer.GetGlyphSize(g,
                RadioButtonState.UncheckedNormal).Width;
            textRectangleValue.Height = ClientRectangle.Height;
        }

        return textRectangleValue;
    }
}

' Define the text bounds so that the text rectangle 
' does not include the radio button.
Public ReadOnly Property TextRectangle() As Rectangle
    Get
        Using g As Graphics = Me.CreateGraphics()
            With textRectangleValue
                .X = Me.ClientRectangle.X + _
                    RadioButtonRenderer.GetGlyphSize(g, _
                    RadioButtonState.UncheckedNormal).Width
                .Y = Me.ClientRectangle.Y
                .Width = Me.ClientRectangle.Width - _
                    RadioButtonRenderer.GetGlyphSize(g, _
                    RadioButtonState.UncheckedNormal).Width
                .Height = Me.ClientRectangle.Height
            End With
        End Using
        Return textRectangleValue
    End Get
End Property
