Subject: accessible drag drop for flash
No previous message | Next message →
Does anyone know of a good development pattern for drag and drop in flash?
(Or, for that matter, html, while we are on the subject). An example we have
to implement in flash is a math question on a test where the student is
asked how much gas one could fill up the tank with given a price and amount.
There would be a flash showing the gas gauge - and the student would be
required to drag the arrow on the gas gauge to the point that it would be
filled (1/4, 1/2, 3/4, full). Any ideas?

Hi Adam,
There are a number of ways that one can provide an alternative to drag and
drop functions in Flash.
One Scenario (ActionScript 3 Example):
On the Flash stage, you can provide 4 Flash buttons/movie clips that
accept keyboard focus. These movie clips may be the 1/4, 1/2, 3/4, and
full movie clips. Ensure a proper event is present so the gauge moves to
the corresponding movie clip image when dragged or activated with the
Enter key.
If it is a movie clip the MSAA role of "button" can be set:
Quarter_full.buttonMode="true";
Quarter_full.tabEnabled="true";
The four buttons must have accessible name's ("quarter full", "half full",
"three-quarters full", "Full" for example).
Quarter_full.accessibilityProperties.name="quarter full";
You may consider placing an accessible description on the object(s):
Quarter_full.accessibilityProperties.description="select this
answer with the Enter key";
Once the user tabs to the object and activates the enter key, the
accessible name should update to include the state of the answer.
Quarter_full.accessibilityProperties.name="quarter full - current
selection";
Ensure that when the accessibility properties change, you set the
updateProperties method:
Accessibility.updateProperties();

Thank you for the reply. I am going to try and implement your idea.

As a screen reader I would suggest a more conventional approach using
multiple choice questions without the drag and drop component. Screen
readers and keyboard users don't do well with drag and drop components.
