Re: [flexcoders] questions about overriding updateDisplayList() for VDividedBox

[Michael Schmalle]

Hi;

Check

C:\Program Files\Adobe\Flex Builder 2.0 Beta 3\Flex SDK 2.0\frameworks\source\mx

I studied that class long and hard. Good luck, there is a lot going on.
I think once you see that class, you will realize you need to do
alittle study ;-)

            My goal is to extend the VDividedBox so that I can minimize/maximize
its children (like the Navigator and Outline panes in flexbuilder, for
example).  I checked out what documentation I could find and I have
some questions.

Are the dividers layed out in layoutChrome()?  If so, when I override
updateDisplayList and change sizes and positions of children, will
layoutChrome get called again? Does updateDisplayList happen again
too?  When I resize the children, do they invalidateDisplayList on
their parent (the VDividedBox)?

The docs say the following: "To size components in the
updateDisplayList() method, you use the setActualSize() method, not
the sizing properties such as width and height. To position a
component, use the move() method, not the x and y properties."  But it
doesn't explain why -- I'm assuming it's so that
parent.invalidateDisplayList() happens.  Is that correct?

Is the source code of the VDividedBox available somewhere so I can see
exactly what's going on?

Thanks,

Tom
