Extending WHS – Adding a new control type

You can now create a new mobile device control as an extension.

Here is how:

1. Create a class that extends WhsControl, and decorate the class with the WhsControlFactoryAttribute attribute specifying the name of your new control.

   Naming considerations for the control name:
   – The name can be any string – prefix it with your organization’s name to avoid clashes.

   – Define it in a class as a public static const property – this allows reuse.

2. Implement the process() and populate() methods on your class. These methods should contain generic handling of the control. Use the members on the WhsControlContext to access and populate the captured fieldValues and other state of the current flow.
3. If any flow specific handling is required, place it in the flow’s processControl() method. For this method to be invoked, the flow must call WhsRFControlData::processDataWithCallback() instead of WhsRFControlData::processData().

This diagram shows how you can plug in your flow – side-by-side with the existing controls:
