Flash MX 2004.
scrollPaneInstance.vPageScrollSize
Property; the number of pixels to move the content in the display area when the user clicks the track in a vertical scroll bar. The default value is 20.
This example creates a ScrollPane instance called my_sp, loads it with an image, and sets the vPageScrollSize property to scroll 30 pixels when the user clicks the track in the vertical scroll bar.
You first drag the ScrollPane component from the Components panel to the current document's library and then add the following code to Frame 1:
/**
Requires:
- ScrollPane component in library
*/
this.createClassObject(mx.containers.ScrollPane, "my_sp", 10);
my_sp.setSize(360, 280);
System.security.allowDomain("http://www.helpexamples.com");
my_sp.contentPath = "http://www.helpexamples.com/flash/images/image1.jpg";
// Scroll 30 pixels when clicking on vertical bar.
my_sp.vPageScrollSize = 30;
