TextField.onSetFocus
739
onScroller
is called whether the scroll position changed because of a users interaction with the
text field, or programmatic changes. The
onChanged
handler fires only if a user interaction causes
the change. These two options are necessary because often one piece of code changes the scrolling
position, while the scroll bar code is unrelated and won't know that the scroll position changed
without being notified.
Example
The following example creates a text field called
my_txt
, and uses two buttons called
scrollUp_btn
and
scrollDown_btn
to scroll the contents of the text field. When the
onScroller
event handler is called, a
trace()
method is used to write information to the log
file. Create two buttons with instance names
scrollUp_btn
and
scrollDown_btn,
and add the
following ActionScript to your FLA or AS file:
this.createTextField("scroll_txt", this.getNextHighestDepth(), 10, 10, 160,
20);
this.createTextField("my_txt", this.getNextHighestDepth(), 10, 30, 320, 240);
my_txt.multiline = true;
my_txt.wordWrap = true;
for (var i = 0; i<10; i++) {
my_txt.text += "Lorem ipsum dolor sit amet, consectetuer adipiscing elit,
sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat
volutpat.";
}
scrollUp_btn.onRelease = function() {
my_txt.scroll--;
};
scrollDown_btn.onRelease = function() {
my_txt.+;
};
my_txt.onScroller = function() {
trace("onScroller called");
scroll_txt.text = my_txt." of "+my_txt.maxscroll;
};
