Scrollpane Component - MACROMEDIA FLASH MX 2004-USING COMPONENTS Use Manual

ScrollPane component

The ScrollPane component displays movie clips, JPEG files, and SWF files in a scrollable area. By
using a scroll pane, you can limit the amount of screen area occupied by these media types. The
scroll pane can display content that is loaded from a local disk or from the Internet. You can set
this content while authoring and at runtime by using ActionScript.
Once the scroll pane has focus, if its content has valid tab stops, those markers receive focus. After
the last tab stop in the content, focus shifts to the next component. The vertical and horizontal
scroll bars in the scroll pane never receive focus.
A ScrollPane instance receives focus if a user clicks it or tabs to it. When a ScrollPane instance has
focus, you can use the following keys to control it:

Left Arrow

For more information about controlling focus, see
on page 50 or "FocusManager class" on page
A live preview of each ScrollPane instance reflects changes made to parameters in the Property
inspector or Component inspector during authoring.
Using the ScrollPane component
You can use a scroll pane to display any content that is too large for the area into which it is
loaded. For example, if you have a large image and only a small space for it in an application, you
could load it into a scroll pane.
You can set up a scroll pane to allow users to drag the content within the pane by setting the
parameter to
