Re: [flexcoders] How to get all children in Application?

[Bjorn Schultheiss]

I dont think there is a built-in function that returns all children.
It wouldn't be difficult to write a recursive function that recurses  
through the display list and gets all child display objects though.

Hi there,

is there a way to get all children in application? in the following
code, I can get the button_1, panel_1 only. However, can't get the
button_2 inside the panel.

can I get all children in whole application without knowing the
container structure?

THANKS
