PresentationText

The PresentationText component is very similar to the PresentationSWF component

discussed in the previous section. With the PresentationText component, you can

create a FlashCom application wherein a set of text slides is controlled by a speaker

and is synchronized with all other connected viewers. Unlike the PresentationSWF

component, however, the PresentationText component does not require a secondary

Flash movie to provide the context of the slideshow, nor does it provide a Viewer

Buttons Enabled parameter. The Forward and Back buttons are visible only if the

user is a presenter, and not to non-presenter participants. The PresentationText com-

ponent is actually a text slide creator and editor. Like the PresentationSWF compo-

nent, the speaker version can create and edit the text, while the viewer version can

only watch and navigate already-viewed slides within the presentation. The speaker

version of the component also provides a list of slide titles within a navigation list-

box, as seen in Figure 2-9.

Nested Flash UI Components

The PresentationText component uses three Flash MX UI components: ListBox,

PushButton, and ScrollBar. You can alter the look of the PushButton component by

changing the appropriate skin symbol in the Component Skins folder within the

Flash document’s Library panel. If you want to change the look of the forward and

back arrows, you can alter the graphics within the movie clip symbols found in the

Client-side component parameters

An instance of the PresentationText component has only one setting in the Proper-

ties panel or Component Parameters panel.
