Description
Event handler; invoked when a text field 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 button to a text field,
oldFocus contains the text field instance.
If there is no previously focused object,
oldFocus contains a null value.

Availability
Flash Player 6.
Usage
my_txt._parent.property
_parent.property
Description
Property; a reference to the movie clip or object that contains the current text field or object. The
current object is the one containing the ActionScript code that references
_parent.
Use
_parent to specify a relative path to movie clips or objects that are above the current text
field. You can use
_parent to climb up multiple levels in the display list as in the following:
_parent._parent._alpha = 20;
Example
The following ActionScript creates two text fields and outputs information about the _parent of
each object. The first text field,
first_txt, is created on the main Timeline. The second text
field,
second_txt, is created inside the movie clip called holder_mc.
this.createTextField("first_txt", this.getNextHighestDepth(), 10, 10, 160,
22);
first_txt.border = true;
trace(first_txt._name+"'s _parent is: "+first_txt._parent);
this.createEmptyMovieClip("holder_mc", this.getNextHighestDepth());
holder_mc.createTextField("second_txt", holder_mc.getNextHighestDepth(), 10,
40, 160, 22);
holder_mc.second_txt.border = true;
trace(holder_mc.second_txt._name+"'s _parent is:
"+holder_mc.second_txt._parent);
