範例

下列程式代碼範例示範如何使用 屬性設定鍵盤快捷方式 HotkeyPrefix 。 它也會示範如何使用 FromSystemColor 方法。 若要執行此範例，請將程式代碼貼到表單中、處理表單的事件 Paint ，並呼叫下列方法，並將 e 傳遞為 PaintEventArgs。

private:
   void ShowHotKey( PaintEventArgs^ e )
   {
      // Declare the string with a keyboard shortcut.
      String^ text = "&Click Here";

      // Declare a new StringFormat.
      StringFormat^ format = gcnew StringFormat;

      // Set the HotkeyPrefix property.
      format->HotkeyPrefix = System::Drawing::Text::HotkeyPrefix::Show;

      // Draw the string.
      Brush^ theBrush = SystemBrushes::FromSystemColor( SystemColors::Highlight );
      e->Graphics->DrawString( text, this->Font, theBrush, 30, 40, format );
   }

private void ShowHotKey(PaintEventArgs e)
{

    // Declare the string with a keyboard shortcut.
    string text = "&Click Here";

    // Declare a new StringFormat.
    StringFormat format = new StringFormat();

    // Set the HotkeyPrefix property.
    format.HotkeyPrefix = System.Drawing.Text.HotkeyPrefix.Show;

    // Draw the string.
    Brush theBrush = 
        SystemBrushes.FromSystemColor(SystemColors.Highlight);

    e.Graphics.DrawString(text, this.Font, theBrush, 30, 40, format);
}

Private Sub ShowHotKey(ByVal e As PaintEventArgs)

    ' Declare the string with keyboard shortcut.
    Dim text As String = "&Click Here"

    ' Declare a new StringFormat.
    Dim format As New StringFormat

    ' Set the HotkeyPrefix property.
    format.HotkeyPrefix = System.Drawing.Text.HotkeyPrefix.Show

    ' Draw the string.
    Dim theBrush As Brush = _
        SystemBrushes.FromSystemColor(SystemColors.Highlight)
    e.Graphics.DrawString(text, Me.Font, theBrush, 30, 40, format)
End Sub
