Usage
my_btn._x
Description
Property; an integer that sets the x coordinate of a button relative to the local coordinates of the
parent movie clip. If a button is on the main Timeline, then its coordinate system refers to the
upper left corner of the Stage as (0, 0). If the button is inside a movie clip that has
transformations, the button is in the local coordinate system of the enclosing movie clip. Thus,
for a movie clip rotated 90 degrees counterclockwise, the enclosed button inherits a coordinate
system that is rotated 90 degrees counterclockwise. The button's coordinates refer to the
registration point position.
