Project 2 Java Applet SXE Interface By Murtuza
DhillaRebecca PingTim Yang

• Objectives

• Create Java applet-based interfaces to the
  sensor execution environment (SXE).
• More specifically, create an interactive
  graphical interface instead of the current text
  based SXE.
• Want it to be more precise, more user-friendly,
  and more dynamic.

3

• Current Interface

• The current text-based SXE is not good because
• Static (HTML only provides static information),
  no interaction (only allowed to view) and no way
  to update the interface
• It does not easily show interrelations of the
  data
• Difficult to tell where you are in Sensorium,
  see example.

4

• Example

Bad because can not tell that rand is a child
of equals. It looks as if they are separate.
5

• Our Approach

J Tree Graph use to represent nodes and the
STEP graph We are using a J-tree representation
because it allows the user to see the
interrelations of how each of the classes work
together and how they relate to each other.

• Classes

• Connection
• Handles all XML/HTTP connections and
  transmissions,Portable.
• XML Parser
• Using a DefaultMutableTreeNode
  (javax.swing.tree.) and the connection object it
  generates all the nodes.
• Nodes are discovered recursively from the step
  node via parents.
• NodeInfo
• Upgrade to DefaultMutable Node tree. Object type
  that is pushed to the Jtree
• XML to GUI (X2G) - Using a connection class
  object it generates the GUI by incorporating
  data from XML Parser into a JTree structure.
