Frage

Ich möchte ein RTF-Dokument in einer SWT anzuzeigen (eigentlich Eclipse RCP) Anwendung.

Ich weiß, es ist ein Swing-Widget für die Anzeige und Bearbeitung von RTF-Text, aber es ist Schaukel und ganz fremd in Aussehen und fühlen, wenn in der ansonsten Plattform verwendet (nicht, dass zur letzten meines Wissens zu erwähnen, es habe keine Bilder angezeigt werden und hatte nur eine begrenzte Unterstützung für die Formatierung)

Weitere Optionen sind COM-Schnittstelle auf Windows zu verwenden, aber das funktioniert nur auf der Windows-Plattform und setzt voraus, dass ein ActiveX-RichEdit contol auf der Kundenmaschine installiert werden ..., die die Bereitstellung der Anwendung machen können ziemlich horrend ...

Was sind die anderen Optionen für Rich-Dokumente in Eclipse / SWT-Anwendung angezeigt wird?

War es hilfreich?

Lösung 5

Actuall habe ich habe gerade ein anderes Widget, das vielversprechend atm ist:

Andere Tipps

Sie können swt.custom.StyledText verwenden. Das hat viele Funktionen, um das Aussehen des Textes zu ändern. Aber ich glaube nicht, dass es RTF laden oder speichern jetzt.

Ich schrieb einmal einen HTML-Editor mit, aber es ist ziemlich schwierig, da das StyledText Modell Stile auf einen Teil des Textes hinzuzufügen ist so fremd gegenüber dem Weg, um HTML / RTF funktioniert.

AFAIK können Sie direkt von dieser Steuerung drucken, die intern eine RTF-Darstellung der Inhalte erzeugt. Aber das ist nicht genau das, was Sie gefragt.

Warum nicht zuerst den RTF-Text in ein StyledDocument lesen Sie die RTFEditorKit und dann den StyledDocument zu einem String Schreiben des HTMLEditorKit mit?

String rtf = "whatever";
BufferedReader input = new BufferedReader(new StringReader(rtf));

RTFEditorKit rtfKit = new RTFEditorKit();
StyledDocument doc = (StyledDocument) rtfKit.createDefaultDocument();
rtfEdtrKt.read( input, doc, 0 );
input.close();

HTMLEditorKit htmlKit = new HTMLEditorKit();       
StringWriter output = new StringWriter();
htmlKit.write( output, doc, 0, doc.getLength());

String html = output.toString();

Und dann die HTML-Anzeige?

Sie können die Swing-Steuerung mit der AWT / SWT überbrücken . Ich habe diese Openoffice in eine SWT App einzubinden:

OOException ist ein Runtime:

package ooswtviewer;

/**
 * Wrapper for all OO exceptions to keep throws clauses in check
 * 
 * @author Aaron Digulla
 */
public class OOException extends RuntimeException
{

    public OOException ()
    {
        super ();
    }

    public OOException (String message, Throwable cause)
    {
        super (message, cause);
    }

    public OOException (String message)
    {
        super (message);
    }

    public OOException (Throwable cause)
    {
        super (cause);
    }

}

Ich bin eine Art und Weise nicht sicher, es zu tun, ohne ActiveX zu verwenden. Wenn Sie diese Richtung tun gehen Sie vielleicht in die IBM Container suchen wollen ActiveX-Dokumente , die angeblich eine bessere Integration von Dokumenten zu ermöglichen.
