DESCRIPTION
The DataBindingExample shows a Royale application that can communicate with
a third-party data source (in this case, yahoo.finance) and display the values
returned using data binding. It also demonstrates that you can use “states” to
control the UI.
This Royale application may be run as a Flash SWF or cross-compiled (using the Royale Compiler)
into JavaScript and HTML and run without Flash.
The DataBindingExample also shows how the model-view-controller (MVC) pattern
can be used to separate the parts of the application. This is facilitated by
the use of Royale beads added to the main application that provide the
data connection (via HTTPService) and interacting with the rest of the application
via events.
COMPONENTS and BEADS
- Button
- CheckBox
- ComboBox
- Container
- Label
- RadioButton
- TextArea
- TextInput
- Data binding: the text properties of TextArea and Label are linked with results
from the remote server calls.
NOTES
The cross-compilation to JavaScript often results in non-fatal warnings. Some of these warnings
should be addressed in future releases of the the Royale Compiler compiler.
