bottomScroll (TextField.bottomScroll property)

An integer (one-based index) that indicates the bottommost line that is currently visible the text field. Think of the text field as a window onto a block of text. The property TextField.scroll is the one-based index of the topmost visible line in the window.

All the text between lines TextField.scroll and TextField.bottomScroll is currently visible in the text field.

Availability: ActionScript 1.0; Flash Player 6

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.
