Creating scrolling text (Flash Professional
Only)
Flash Lite 1.1 supports the
scroll
and
maxscroll
text field properties, which let you create
scrolling text fields. The
scroll
property specifies the first visible line in a text block; you can
get and set its value. For example, the following code scrolls the text field whose variable name
is
story_text
down by five lines:
story_text.= 5;
The
maxscroll
property specifies the first visible line in a text block when the last line of the
text is visible in the text block; this property is read-only. You can compare a text field’s
maxscroll
property to its
scroll
property to determine how far a user has scrolled within a
text field. This is useful if you want to create a scroll bar that provides feedback about the
user’s current scroll position relative to the maximum scroll position.
