DoubleAnimationUsingKeyFrames をコードで書くと、次のように面倒なことになるので、XAMLで書いて、トリガーで起動するようにしたほうがいい。とはいえ、動的にストーリーボードやトリガーをエディタで設定しておいて、それをC#で書き直すときに、デザイナーが処理できるように気をつかってあげないと、デザイナーが表示できなくなる。

private void StoryBoardScale(Storyboard sb, Label label)
{
    DoubleAnimationUsingKeyFrames daukfX = new DoubleAnimationUsingKeyFrames();
    DoubleAnimationUsingKeyFrames daukfY = new DoubleAnimationUsingKeyFrames();

    ScaleTransform scaleTransform = new ScaleTransform();
    label.RenderTransform = scaleTransform;
    string name = "labelS" + num++;
    this.RegisterName(name, scaleTransform);

    daukfX.BeginTime = new TimeSpan(0, 0, 0);
    daukfX.Duration = new TimeSpan(0, 0, 60);
    daukfX.KeyFrames.Add(
         new SplineDoubleKeyFrame(
             0.1,
             KeyTime.FromTimeSpan(new TimeSpan(0, 0, 0))));
    daukfX.KeyFrames.Add(
        new SplineDoubleKeyFrame(
            5.0,
            KeyTime.FromTimeSpan(new TimeSpan(0, 0, 60))));

    Storyboard.SetTargetName(daukfX, name);
    Storyboard.SetTargetProperty(daukfX, new PropertyPath(ScaleTransform.ScaleXProperty));

    sb.Children.Add(daukfX);

    daukfY.BeginTime = new TimeSpan(0, 0, 0);
    daukfY.Duration = new TimeSpan(0, 0, 30);
    daukfY.KeyFrames.Add(
         new SplineDoubleKeyFrame(
             0.1,
             KeyTime.FromTimeSpan(new TimeSpan(0, 0, 0))));
    daukfY.KeyFrames.Add(
        new SplineDoubleKeyFrame(
            5.0,
            KeyTime.FromTimeSpan(new TimeSpan(0, 0, 60))));

    Storyboard.SetTargetName(daukfY, name);
    Storyboard.SetTargetProperty(daukfY, new PropertyPath(ScaleTransform.ScaleYProperty));

    sb.Children.Add(daukfY);
}

WPFアプリケーションの中で、RichTextBox のHyperlink で、NavigationUri をセットしても、Clickイベントがキックされない。

RichTextBox のHyperlink は、NavigationWindow or Frame で navigation がサポートされているときだけ

という記事があるが、本当？

ということで、WPFアプリケーションの中で、RichTextBox のHyperlink をクリックしたときに、そのURLを開くには、MouseLeftButtonDown を使って、こんな感じ

<RichTextBox Height="100" Name="richTextBox1" Width="200" >
    <FlowDocument>
        <Paragraph>
            <Run>Paragraph 1</Run>
            <Run>Paragraph 2</Run>
            <Label >hello</Label>
            <Hyperlink NavigateUri="http://uchukamen.com"  MouseLeftButtonDown="Hyperlink_MouseLeftButtonDown"  >
                <Run>http://uchukamen.com</Run>
            </Hyperlink>
        </Paragraph>
    </FlowDocument>
</RichTextBox>

private void Hyperlink_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    System.Diagnostics.Process.Start(((Hyperlink)sender).NavigateUri.ToString());
}

=================

とするか、コードで書く場合は、

var fd = new FlowDocument();
this.RTB.Document = fd;

var p = new Paragraph();
p.Inlines.Add("ハイパーリング");

Hyperlink l = new Hyperlink();
l.Inlines.Add(http://uchukamen.com);
l.NavigateUri = new Uri("http://uchukamen.com");
l.MouseLeftButtonDown +=new MouseButtonEventHandler(l_MouseLeftButtonDown);

p.Inlines.Add(l);

fd.Blocks.Add(p);

——————————–

void l_MouseLeftButtonDown(object sender, RoutedEventArgs e)
{
    System.Diagnostics.Process.Start(((Hyperlink)sender).NavigateUri.ToString());
}
