ActionScript language elements
After you specify an accessibility property, you can't revert its value to avalue set in the
Accessibility panel. However, you can set the property to itsdefault value (
false
for Boolean
values; empty strings for stringvalues) by deleting the property from the
_accProps
object, as
shownin the following example:
my_mc._accProps.silent = true; // set a property
// other code here
delete my_mc._accProps.silent; // revert to default value
The value of _accProps must be an object. This means that if no
_accProps
objectalready
exists, you must create one before you can assign clues to the propertiesof the
_accProps
object.
if (_accProps == undefined)
{
_accProps = new Object();
}
_accProps.name = "My movie";
Availability:
ActionScript 1.0; Flash Player 6,0,65,0
