Example
The following example creates a text field and fills it with text. You must insert a button (with
the instance name "my_btn"), and when you click it, the
scroll
and
bottomScroll
properties for the text field are then traced for the
comment_txt
field.
this.createTextField("comment_txt", this.getNextHighestDepth(), 0, 0, 160,
120);
comment_txt.html = true;
comment_txt.selectable = true;
comment_txt.multiline = true;
comment_txt.wordWrap = true;
comment_txt.htmlText = "<b>What is hexadecimal?</b><br>"
+ "The hexadecimal color system uses six digits to represent color
values. "
+ "Each digit has sixteen possible values or characters. The characters
range"
+ " from 0 to 9 and then A to F. Black is represented by (#000000) and
white, "
+ "at the opposite end of the color system, is (#FFFFFF).";
my_btn.onRelease = function() {
trace("scroll: "+comment_txt.scroll);
trace("bottomScroll: "+comment_txt.bottomScroll);
};
The
MovieClip.getNextHighestDepth()
method used in this example requires Flash Player
7 or later. If your SWF file includes a version 2 component, use the version 2 components
DepthManager class instead of the
MovieClip.getNextHighestDepth()
method.
