removing external Content
P Note: If you want to
remove the ProLoader
object from the Stage
entirely, you can use
the removeChild().
command. The code
removeChild
(myProLoader)
removes the ProLoader
object called
myProLoader so that it
is no longer displayed
on the Stage.
Once an external SWF file is loaded, how do you unload it to return to the main
Flash movie? One way is to unload the SWF content from the ProLoader object, so
the audience can no longer see it. You will use the command unload() to do this.
1 Select the first frame of the actionscript layer and open the Actions panel.
2 Add the following lines to your code in the Script pane:
myProLoader.addEventListener(MouseEvent.CLICK, unloadcontent);
function unloadcontent(e:MouseEvent):void {
myProloader.unload();
}
P Note: If your loaded
content contains
open streams (such
as video or sounds),
those sounds may
continue even after
you’ve unloaded
the SWF from the
ProLoader object. Use
the unloadAndStop()
command to extinguish
the sounds as well
as unload the SWF
content.
This code adds an event listener to the ProLoader object called myProLoader.
When you click on the ProLoader object, the function called unloadcontent is
executed.
The function performs just one action: It removes any loaded content from the
ProLoader object.
3 Choose Control > Test Movie > in Flash Professional to preview the movie.
Click on any of the four sections, and then click on the loaded content to return
to the main movie.
