Creating an application with the ScrollPane component
The following procedure explains how to add a ScrollPane component to an application while
authoring. In this example, the scroll pane loads a SWF file that contains a logo.
To create an application with the ScrollPane component:
1. Drag a ScrollPane component from the Components panel to the Stage.
2. In the Property inspector, enter the instance name myScrollPane.
3. In the Property inspector, enter logo.swf for the contentPath parameter.
4. Select Frame 1 in the Timeline, open the Actions panel, and enter the following code:
scrollListener = new Object();
scrollListener.scroll = function (evt){
txtPosition.text = myScrollPane.vPosition;
}
myScrollPane.addEventListener("scroll", scrollListener);
completeListener = new Object;
completeListener.complete = function() {
trace("logo.swf has completed loading.");
}
myScrollPane.addEventListener("complete", completeListener);
