Flash Player 6 (6.0.79.0).
Flash MX 2004.
scrollBarInstance.lineScrollSize
Property; gets or sets the number of lines or pixels scrolled when the user clicks the arrow buttons of the UIScrollBar component. If the scroll bar is oriented vertically, the value is a number of lines. If the scroll bar is oriented horizontally, the value is a number of pixels.
The default value is 1.
The following example creates a scroll bar to scroll text in a text field, which it loads from a web page. The example sets the lineScrollSize property to scroll two lines at a time for each click of an arrow button:
/**
Requires:
- UIScrollBar component in library
*/
this.createTextField("my_txt", 10, 10, 20, 200, 100);
my_txt.wordWrap = true;
this.createClassObject(mx.controls.UIScrollBar, "my_sb", 20);
// Set the target text field.
my_sb.setScrollTarget(my_txt);
// Size it to match the text field.
my_sb.setSize(16, my_txt._height);
// Move it next to the text field.
my_sb.move(my_txt._x + my_txt._width, my_txt._y);
// Scroll 2 lines per click on scroll arrow.
my_sb.lineScrollSize = 2;
// Scroll 5 lines per click on scroll track.
my_sb.pageScrollSize = 5;
// Load text to display and define onData handler.
var my_lv:LoadVars = new LoadVars();
my_lv.onData = function(src:String) {
if (src != undefined) {
my_txt.text = src;
} else {
my_txt.text = "Error loading text.";
}
};
my_lv.load("http://www.helpexamples.com/flash/lorem.txt");
