Displaying HTML In Java Window

• First- Why is this important?
• Virtual Classroom
• Ability to surf to work-related hyperlinks while
  viewing a lecture
• Virtual NYC
• Ability to link locations to websites
• Eg. Clicking on Pizza Hut can open the Pizza Hut
  website.

Java

• Javas swing component is capable of displaying
  HTML pages.
• HTML pages are viewed using a JEditorPane
• This supports styled text.

4
JEditorPane

• Currently knows about 3 types of content
• text/plain-uses DefaultEditorKit
• Editor Kits are contain classes that write
  content to the JEditorPane.
• text/html-uses HTMLEditorKit
• text/rtf-uses RTFEditorKit

5
HTMLEditorKit

• This kit contains classes for displaying various
  html objects.
• How it works?
• Load a HTML file into the JEditorPane object and
  the editor kit will dictate how the HTML objects
  are displayed in the window-very similar to a web
  browser.
• In fact, I found a very simple Java web browser
  that uses a JEditorPane for its display.

Example of Code
private JEditorPane createEditorPane()
JEditorPane editorPane new JEditorPane()
editorPane.setEditable(false)
java.net.URL helpURL TextSamplerDemo.class.getRe
source( "google.html") if (helpURL !
null) try
editorPane.setPage(helpURL) catch
(IOException e)
System.err.println("Attempted to read a bad URL
" helpURL) else
System.err.println("Couldn't find file
TextSampleDemoHelp.html")
return editorPane

Dashboard Implicit Query

• Dashboard- Linux
• Implicit Query- Mircrosoft
• Both have same principles
• Instantaneous and continuous search of your
  workspace for relevant objects

9
Dashboard Implicit Query

• Idea
• Dashboard/Implicit Query continuously monitor
  you current workspace, all open windows such as
  chat windows websites and searches for keywords
  or cluewords and will return any possible
  relevant information on those keywords to the
  Dashboard interface.
