theButton._x

Description

The floating-point _x property indicates the horizontal position of theButton’s registration

point. It is measured relative to one of two possible coordinate spaces:

•If

theButton resides on the main timeline, _x is measured relative to the Stage’s left

edge.

•If

theButton resides on a movie clip instance’s timeline, _x is measured relative to the

registration point of that parent instance.

The

_x property (along with all horizontal coordinates in Flash) increases to the right and

decreases to the left.

Button._x is directly analogous to MovieClip._x; see that property ...
