i can not see this CairngormEvent.swc i don't know which .swc file could i add in lib? thanks.
It is not very obvious what in particular are you asking but I'll try to answer all the possible questions (as far as I can see).
First of all I guess you're using Cairngorm 2 in your project.
Ok. In case of absence of Cairngorm library (I mean Cairngorm.swc) which contains CairngormEvent class you can download it here. You need to choose binary package and place it to the libs folder of your project.
To have possibility to view class' source code you need to download ZIP archive with sources and attach them to the Cairngorm.swc. Just unpack them somewhere first. Then got to the project's properties > Flex Build Path > Library Path then select your Cairngorm.swc, expand it, select Source attachment item and point recently unpacked folder with sources. So now you can press F3 and navigate sources.
