一个另类的swapChildren的实现

一个另类的swapChildren的实现

 

I’m working on a project right now and swapChildren is just not working as expected. 

Looked around a bit, and I just decided to remove the two children and add copies of them instead:

var tmpThis:Canvas= EV.target as Canvas;

var tmpHighest:Canvas= highestPanel;

removeChild (highestPanel);

removeChild (EV.target as Canvas);

addChild(tmpHighest);

addChild(tmpThis);

can1.swapChildrenAt(1, 0);
