ActionScript Pagination Example

NOTE: Updated to TLF Build 460.

The Pagination example in the TextLayoutFramework is posted to build with Adobe Flash CS4 Professional and the TextLayout plugin. Its also possible to build this example with Flex as an ActionScript only project. It does require the Flex 3.2 or Flex gumbo SDK.

I’ve posted the actionscript version that builds with Flexbuilder here: Download file

This version doesn’t have the buttons the Flash Pro version has. Use page up/page down to switch between chapters and the arrow keys to move between pages.

Both the ActionScript version and the Flash Pro version use to manage the paginated view. This is example code that you can use to build your own paginated view. The pagination widget adds new containers until all the text is in a container and then displays some number of containers emulating columns. It supports resizing the visible area. One of the goals was to avoid recomposing every time the visible area changed by a small amount. Hence the decision to relayout during resize has some heuristics.

Note that the labs release has bugs (since fixed) in displaying selections when some of the containers are not visible. This example doesn’t make use of an interactionManager due to those bugs.
