Learning Objectives

This example demonstrates how to read and write an xml file to the file system leveraging ofXML.

In the code, pay attention to:

• Use ofXML to read an xml file from the file system with XML.load("mySettings.xml")

• Writing an xml file to the file system with XML.save("mySettings.xml")

• Adding childNodes to the xml with XML.addChild and appending with XML.addXML

• Parsing and traversing XML with XML.exists(), XML.getValue(), XML.setToSibling(),XML.setToParent(), XML.setTo(),XML.getName()

• A black background, with a thin column on the left and a large filled rect on the right
• Text instructions at the top and at the bottom of the screen.
• A line drawn on the right canvas

When the mouse is pressed, the application :

• starts to record the drag movement.
• As the mouse is dragged across the canvas, the path is drawn in a thin stroke to the canvas.
• The background will changing color randomly with mouse movement
• Drag coordinates, along with the background color are captured in an xml structure while dragging

When the key s is pressed:

Instructions for use:

• Press down on the canvas with the mouse and start dragging the mouse while holding down.
