Components in Live Preview

The Live Preview feature, enabled by default, lets you view components on the Stage as they will
appear in the published Flash content; the components appear at their approximate size. The live
preview reflects different parameters for different components. For information about which
component parameters are reflected in the live preview, see each component entry in
"Components Dictionary," on page

About using a preloader with components

Components are set to Export in First Frame by default. This causes the components to
load before the first frame of an application is rendered. If you want to create a preloader for
an application, deselect Export in First Frame for any compiled clip symbols in your library.
Note: If you're using the ProgressBar component to display loading progress, leave Export in First
Frame selected for the progress bar.

About loading components

If you load version 2 components into a SWF or into the Loader component, the components
may not work correctly. These components include the following: Alert, ComboBox, DateField,
Menu, MenuBar, and Window.
