11.22. Using Tables to Arrange Form Elements
You want to use ActionScript to arrange the elements of a form on the screen.
Create and use a custom
You can use ActionScript to control the position of any graphical
object such as a movie clip, a button, or a text field, using the
Additionally, each graphical object has properties that return its
height and width (
_width). You can use these properties in concert
to position instances on the Stage relative to one another.
For example, we can position a movie clip horizontally such that its
x coordinate is five pixels to the right of a text field. The text
_x property plus its
_width property yields the x coordinate of the
right edge of the text field. In this example, we add five pixels to
allow for spacing between the movie clip and the text field. We also
align the top of the movie clip with the top of the text field.
myMovieClip_mc._x = myTextField_txt._x + myTextField_txt._width + 5; myMovieClip_mc._y = myTextField_txt._y;
In this example, we position the movie clip such that its y
coordinate is five pixels below the bottom of the text field. This
example is similar to the preceding one but uses the
_height properties to
calculate the vertical position. We also align the left edges of the
movie clip and the text field.
myMovieClip_mc._y = myTextField_txt._y + myTextField_txt._height + 5; myMovieClip_mc._x = myTextField_txt._x;
