FlashDevelop - Why does code-completion not work with mx.controls

Question

Today's my first day with Flex and FlashDevelop. In my ActionScript file, I have this line.

import flash.display.SimpleButton;

FlashDevelop is aware about this and Code-completion works fine.

But, when I have this line.

import mx.controls.Button;

Then code-completion doesn't work.

Answer 1

Works perfectly well for me w/o doing anything special. But maybe your project's properties got borked. Do this:

Open Project Properties
Go to Compiler Options tab
In Advanced -> Intrinsic Libraries add the following
Library\AS3\frameworks\Flex3
