---===ObjectGraph Example===---

This is a very simple example of how you can use the ObjectGraph
widget.  For a more in depth example, see the included ST filein
called "GrfBrows.st".

---STEP 1---
Install ObjectGraph (see installation instructions for more information).

---STEP 2---
Open a new canvas and the palette tool.

---STEP 3--- 
Put a button on the canvas.  Put an ObjectGraph on the canvas (make it
at least a couple inches wide and tall).

Open the Properties Tool on the ObjectGraph you just placed on the
canvas.  Set the aspect to be "graphModel", change the orientation to
"Horizontal", and make the ID "#theGraph".  Apply the changes and
click the "Details" section of the Properties Tool.  Change the Get
Name Msg to "#printString".  Apply those changes.

Open the Properties Tool on the button you added.  Change the label to
"Flip" and the action to "#flipButton".

Install the canvas as a subclass of ApplicationModel with the name
ObjectGraphTest.  Then go to the definer and add the initializations
for flipButton and graphModel.

---STEP 4---
Open a System Browser (or your favorite method browser) on the newly
created ObjectGraphTest class (make sure you are viewing the Instance
methods).  Change flipButton to:

   flipButton
      "Flip the orientation of the graph"
      
      (self builder componentAt: #theGraph) widget flip.

Create a new method in the protocol "interface opening":

   postOpenWith: aBuilder
      "Build the graph"
      
      self graphModel value buildTreeFrom: (Array with: Number).

---STEP 5---
Open the new application.  This is a simple hierarchy browser on the
Number class.

---STEP 6---
See the file README.TXT for legal information and pointers on how to
get started using ObjectGraph.  For a better example, see the section
in README.TXT on getting started.

Good Luck,
