| 2 | This file demonstrates how the dojox.wire code can be used to do declarative |
|---|
| 3 | wiring of events. Specifically, it shows how you can chain actions together |
|---|
| 4 | in a sequence. In this case the setting of a value on one textbox triggers a |
|---|
| 5 | copy over to another textbox. That in turn triggers yet another copy to another |
|---|
| 6 | text box. |

| 104 | Note that this uses the basic 'property' form of copying the property over and setting it. The Wire |
|---|
| 105 | code supports both getX and setX functions of setting a property as well as direct access. It first looks |
|---|
| 106 | for the getX/setX functions and if present, uses them. If missing, it will just do direct access. Because |
|---|
| 107 | of the standard getValue/setValue API of dijit form widgets, these transfers work really well and are very compact. |
