As I’m doing some writing for the Flex for Dummies book I was digging into the source code for Panel and the other containers. I was writing about how Panel allows you to set the layout<\/code> property to either absolute<\/code>, vertical<\/code>, or horizontal<\/code>, just like LayoutContainer (or Application, which extends LayoutContainer). My initial thought was that Panel probably just extends LayoutContainer and that’s where we get the layout<\/code> property from. But then digging in I saw that both LayoutContainer and Panel independently implement the layout<\/code> property (in basically a cut and paste exact same way). Unless I’m missing something there’s no reason why Panel shouldn’t just extend LayoutContainer. (BTW, for a recent writeup of the LayoutContainer class see Ben Clinkinbeard’s post here<\/a>).<\/p>\n

If you look at the setter for the layout<\/code> property it’s almost identical in both Panel and LayoutContainer. And take a look in measure()<\/code> and updateDisplayList()<\/code> and you’ll see the same calls to layoutObject.measure()<\/code> and layoutObject.updateDisplayList()<\/code>. <\/p>\n

So I dunno, just thought it was interesting. Really I’m just procrastinating while I’m supposed to be writing. \ud83d\ude1b OK, back to work…<\/p>\n","protected":false},"excerpt":{"rendered":"
