I have an about dialog in Swing that uses a JEditorPane to display an html document (setContentType("text/html");).
I want to creat an about dialog in an Eclipse SWT application and display this same html document which will be displayed formatted (hyperlinks, br etc) same as it did in Swing.
How could I do this? What is the appropriate widget? StyledText?
I started with a Browser in a Handler: 

@Execute
    public void execute(final Shell currentShell){  
      //load html file in textReader
        Browser browser = new Browser(currentShell, SWT.NONE);  
        browser.setText(textReader.toString());  
    }

But nothing is displayed. What is the proper way to resolve this?

Update: Tested @Baz change: 

@Execute
    public void execute(final Shell currentShell){  
        currentShell.setLayout(new FillLayout());  
        //load html file in textReader  
        Browser browser = new Browser(currentShell, SWT.NONE);
        browser.setText(textReader.toString());
        currentShell.pack();
}

It completelly ruins the application! The html is loaded covering the existing elements

    You can always use the good old JFace Dialog with an embedded Browser widget:

    public class BrowserDialog extends Dialog {

    private String browserString;

    protected BrowserDialog(Shell parentShell, String browserString) {
        super(parentShell);
        this.browserString = browserString;
    }

    @Override
    protected Control createDialogArea(Composite parent) {
        Composite composite = (Composite) super.createDialogArea(parent);

        GridLayout layout = new GridLayout(1, false);
        composite.setLayout(layout);

        GridData data = new GridData(SWT.FILL, SWT.FILL, true, true);
        data.widthHint = 400;
        data.heightHint = 400;
        composite.setLayoutData(data);


        Browser browser = new Browser(composite, SWT.NONE);
        browser.setText(browserString);
        browser.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

        return composite;
    }

    @Override
    protected void createButtonsForButtonBar(Composite parent) {
    }

    @Override
    protected void configureShell(Shell newShell) {
        super.configureShell(newShell);
        newShell.setText("About");
    }

    @Override
    public void okPressed() {
        close();
    }

    public static void main(String[] args)
    {
        final Display display = new Display();
        Shell shell = new Shell(display);

        Color gray = display.getSystemColor(SWT.COLOR_WIDGET_BACKGROUND);

        String hex = String.format("#%02x%02x%02x", gray.getRed(), gray.getGreen(), gray.getBlue());

        new BrowserDialog(shell, "<body bgcolor='" + hex + "'><h2>TEXT</h2></body>").open();
    }

}

    Looks like this:

    enter image description here

    If you want the dialog buttons, just replace the createButtonsForButtonBar(Composite parent) method with this:

    @Override
protected void createButtonsForButtonBar(Composite parent) {
    createButton(parent, Dialog.OK, "OK", true);
    createButton(parent, Dialog.CANCEL, "Cancel", false);
}

    Then it will look like this:
