Event handler; invoked when a button receives keyboard focus. The oldFocus parameter is the
object that loses the focus. For example, if the user presses the Tab key to move the input focus
from a text field to a button,
oldFocus contains the text field instance.
If there is no previously focused object,
oldFocus contains a null value.

Usage
my_btn._quality
Description
Property (global); sets or retrieves the rendering quality used for a SWF file. Device fonts are
always aliased and therefore are unaffected by the _quality property.
Note: Although you can specify this property for a Button object, it is actually a global property, and
you can specify its value simply as
_quality. For more information, see _quality.
