[flexcoders] Re: Tree Custom ItemRenderer - I need help
the issue I am not understanding here is, when I add the second line label,
this causes all labels including the root label, to be pushed up so that they
do not align with their icon. there is something I am not understanding as to
how this works. I add the checkbox to the leaf branch at y=0 and that works ok
- it (checkbox) aligns with the label and icon for the leaf. Then I add the
second line at checkbox.y + checkbox.height + 15px line spacing. Now all the
labels are pushed up above their icons, about the height of the new label I
added. what am I missing here that is causing the labels to no longer be
aligned with their icons?

Looks like you want a 15 pixel gap (you are adding 15 in updateDisplayList)
but that is not accounted for in the measure() method.

the name of the file is TwoLines.zip The problem is, when I add the second
line (in CreateChildren()), the label is pushed up away from the icon. I am
sure I am doing something stupid. I have included a screen print of the
output in the src directory of the .zip file.

Flex 3.x
I have been trying to construct a Tree Custom ItemRenderer that has
basically 2 lines on the terminal branches. the first line should show the
file icon and the label, and the second line right below the first line
should show another label. It seems simple, yet when I try to do this the
top label winds up being pushed above the file icon, so there is something
I am missing here.
Does anyone know how to do this or better yet can provide me an example
that explains how to do it?
Thanks,

[flexcoders] Re: Tree Custom ItemRenderer - I need help
Let me see if I can strip it out into a mini-app that doesn't contain proprietorial stuff, so that I can post it. So it sounds like this is do-able? --- In flexcoders@yahoogroups.com, Alex Harui aharui@... wrote: Post your code.

Hello all. I am using Flex 4 and am trying to do My First FlexUnit Project :)
following the instructions at:

or where it is? The code from the page above is below.
Thanks,

[flexcoders] Positioning Issue, trying to add UIComponent to HBox at run time
Hello all, I am constructing an image from some swfs at run time, I do this by creating a UIComponent and adding the swfs to it using Loader. When done, I add the UIC to an HBox I have on the screen. No matter what I do with setting x y, the UIC appears with the top left corner exactly in the center of the HBox. I do not understand what I am doing wrong but I suspect it has to do with Flex not knowing the size of the parent HBox at run time, since it starts out empty. Could you please offer any suggestions or links that could help me to understand what I am not doing right. If I am posting in the wrong group, please let me know and accept my apologies for wasting your time. Thank you so much, Libby
[flexcoders] How do you create a label on a border?
FB3 I need to put an oval text thing superimposed onto the top of a VBox. Would this be a skin for the VBox border or some other technique? It would be nice to be able to do it in .css if possible. I have no idea how to proceed. Please point me in the right direction, maybe a tutorial or a sample. Thanks, Libby
