Class HTMLViewer

  • All Implemented Interfaces:
    java.awt.event.WindowFocusListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.awt.print.Printable,, java.util.EventListener, javax.accessibility.Accessible, javax.swing.event.HyperlinkListener, javax.swing.RootPaneContainer, javax.swing.WindowConstants, StatusHandler
    Direct Known Subclasses:
    DocViewer, WelcomeWindow

    public class HTMLViewer
    extends TableauFrame
    implements java.awt.print.Printable, javax.swing.event.HyperlinkListener
    This class is a toplevel frame that can view HTML documents. This class supports hyperlinks, and has a particular feature to force hyperlinks to be opened in a browser. To do that, specify a hyperlink by giving a fragment (also called a reference) as "in_browser". For example, the following URL will be opened in a browser:
     <a href="">
    If the URL is about:copyright, then the copyrights will be generated by GenerateCopyrights.generateHTML(Configuration)

    If the URL is about:configuration, then the Ptolemy II configuration will be expanded by and the MoML of the configuration will be returned. This is a good way to test the configuration.

    If the URL starts with ptdoc:, then the Ptolemy documentation is opened. For example

     < a href="">HTMLViewer</a>
    will open the Ptolemy documentation for this class. For details see GetDocumentationAction.

    If the URL starts with $CLASSPATH then the classpath is searched.

    This class supports printing and will save the text to a .html file. The url that is viewed can be changed by calling the setPage method.

      • hyperlinkUpdate

        public void hyperlinkUpdate​(javax.swing.event.HyperlinkEvent event)
        React to a hyperlink being clicked on in the rendered HTML. This method opens the hyperlink URL in a new window, using the configuration. This means that hyperlinks can reference any file that the configuration can open, including MoML files. It is assumed this is called in the AWT event thread.
        Specified by:
        hyperlinkUpdate in interface javax.swing.event.HyperlinkListener
        event - The hyperlink event.
      • print

                         int index)
                  throws java.awt.print.PrinterException
        Print the documentation to a printer. The documentation will be scaled to fit the width of the paper, growing to as many pages as is necessary.
        Specified by:
        print in interface java.awt.print.Printable
        graphics - The context into which the page is drawn.
        format - The size and orientation of the page being drawn.
        index - The zero based index of the page to be drawn.
        PAGE_EXISTS if the page is rendered successfully, or NO_SUCH_PAGE if pageIndex specifies a non-existent page.
        java.awt.print.PrinterException - If the print job is terminated.
      • setBase

        public void setBase​( base)
        Set the base URL for relative accesses.
        base - The base for relative hyperlink references.

                            int height)
        Override the base class to set the size of the scroll pane. Regrettably, this is necessary because swing packers ignore the specified size of a container. If this is not called in the AWT event thread, then execution is deferred and executed in that thread.
        setSize in class java.awt.Window
        width - The width of the scroll pane.
        height - The height of the scroll pane.
      • setText
