So if a component is like a movie clip, how can you
tell a component apart from a movie clip? The

Many of the components featured in this book are from Eyeland Studio's Flash Foundry product. Similar components can be found at www.eyeland.com or www.flashcomponents.com .
The default component icon is this: . The standard movie clip icon is this: . If you see the default component icon, then you know you're dealing with a component.
However, Macromedia has provided several icons that you can use for components and has introduced the capability to create custom component icons. Any resource that displays one of the following icons will also be a component. Fortunately, both the alternative icons and custom icons are not used very frequently. Most components simply utilize the default component icon.
See Chapter 11 for information on how to create a custom icon for your components.
When you see an item on the stage, it can be difficult to determine if it is a component or some other type of Flash resource (movie clip, button, graphic symbol, etc.). As with any Flash resource, if you are in doubt about what kind it is, you can always select it and look at the Properties panel. For example, Figure 1.3 shows the Properties panel for a movie clip. You can tell at a glance that the object is a movie clip because of its icon and its Movie Clip label.
Figure 1.3: The Properties panel clearly indicates what type of object you have selected-in this case, a movie clip.
When a component is selected, the Properties panel
can take on several
Figure 1.4: The Properties panel displays several indicators when you have selected a component.
The Parameters tab is displayed in Figure 1.4; this tab is only visible when a component is selected. Also, notice the area within the Properties panel that looks like a small database field. This is probably the most noticeable indication that a component is selected: these are the parameters for the component.
This area is referred to as the
Figure 1.5: The component user interface is like a control panel on a machine.
So if a component is like a machine that makes a doohickey, then the component UI is like the machine's control panel that lets you tell the machine to make a red doohickey rather than a blue doohickey.
Figure 1.6 shows the Properties panel for a selected component with a different type of parameter user interface-in this case, a custom user interface. We will look at component UIs and parameters, including custom UIs, in detail in Chapter 2 (and, really, throughout this book).
