a .fla is 500 x 300. Inside, content moves OUT of the 500 x 300 stage so that it appears like it hides or moves off of the screen.
.fla complied... loaded into Flex via SWFLoader:
<mx:Conainer width="500" height="300">
<mx:SWFLoader width="100%" height="100%" />
</mx:Conainer>
Loaded .swf file shows outside of the 500 x 300 Container in Flex.
How can i get it so that only what is INSIDE of the Container is visible?
Ok, i figured it out.
<mx:Canvas id="swfHolder" mask="{maskCanvas}">
<mx:SWFLoader id="swffer" scaleContent="true" />
</mx:Canvas>
<mx:Canvas id="maskCanvas" backgroundColor="#000000"/>
The trick is to use the "mask" property. Note the object doing the "masking" must have a backgroundColor property set. I found this article helpful: link text
