[flexcoders] Grid with header sections spanning the whole grid

[ozziegt]

I need to build a DataGrid that has header rows which span the whole
grid. Basically, it's an invoice and items on the invoice are grouped
by type. For each group, I want to have a row which spans across the
whole grid, with text that will also span across multiple columns.

I am hoping I can do this with the AdvancedDataGrid control but I
haven't had much luck with the key requirement of having header rows
that can span multiple columns. I also don't want it to have a tree
structure. Any suggestions?

Thanks

[flexcoders] Making the row of a DataGrid bold

[ozziegt]

I have a 5 column DataGrid, and I need certain rows to be bold (kind
of like an e-mail client). Is there any easy way to do this in Flex?

Thanks in advance

[ozziegt]

Thanks. It's working great...too bad it requires an AdvancedDataGrid
though.

[flexcoders] Creating an URL to a subsection of UI

[ozziegt]

I have a pretty complicated UI with 2-3 layers of tab-like navigation.
So imagine if you will, a top level menu of 3-4 items, and then under
each of those another submenu of a few items. I want to be able to
create an URL to point to one of those subitems. Is there any way to
do this in flex?

Currently what I am planning on doing is taking an url parameter which
specifies the destination and then using that to manipulate the UI and
show the page I need to show. But I wanted to make sure there wasn't a
built-in or better way to do it.

Thanks

[flexcoders] Application.application.parameters doesn't hold GET query parameters

[ozziegt]

I feel kind of stupid asking this, but I have been beating my head
against the wall and I know I am missing something obvious.

I created a sample app here (you can view source on it):
http://osmanu.com/flex/UrlParams/UrlParams.html?foo=bar

You will notice there are no URL parameters being reported by the
application. The code is pretty basic, so I don't know what I am
missing. This is a brand new sample app...I created it, added a few
lines of code, and that is it. Any ideas? 

Thanks

private function showParams():void
{
var params:Object = Application.application.parameters;
var s:String = Params: \n;
params.runtime = added in code;
for (var key:String in params)
{
s += key +: + params[key] + \n;
}
txt.text = s;
}

[flexcoders] Re: Application.application.parameters doesn't hold GET query parameters

[ozziegt]

Well, the documentation sure says so: 

http://livedocs.adobe.com/flex/3/langref/mx/core/Application.html#parameters

I had it working with swfobject using the getQueryParamValue function
in JS. I think I my just stick with that, and use swfaddress for my
deep linking. Still would like to know what is up with the
documentation though. All my web searches seem to imply that it just
supposed to work.

Thanks

 I don't believe Flash natively reads URL parameters from the
browsers query
 string.
 However, here are a few ways you can do it:
 
- Write a javascript (or serverside) method that takes the
browsers query
string and the passes them in as flashvars.
- You CAN add a query string directly to the embed code, (ex
UrlParams.swf?foo=bar), Those will be treated as flashvars as well.
- If you have javascript access on the page, add an ExternalInterface
call which will return the query string to your swf.
 
 Hope that helps,

[ozziegt]

Thanks for all the replies. Yeah I thought about it over lunch and it
occurred to me that I might only get the params when I reference the
.swf file directly. I think I will stick with my current
implementation using swfobject.

[flexcoders] Re: Creating an URL to a subsection of UI

[ozziegt]

Thanks.

Since I am using swfobject, I am going to also use swfaddress, and
maybe use the wrapper to BrowserManager found here:
http://developer.iconara.net/objectlib/flex-browsermanager-swfaddress.html

My question now is whether or not there is a benefit in using
BrowserManager instead of using swfaddress directly?

Thanks

[flexcoders] Re: Anything other than a JS alert can delay a window close?

[ozziegt]

We have had success in onBeforeUnload, make the final request, and
then in onUnload, create a 500ms loop in JS which gives the networking
layer enough time to put the request on the wire before the flash is
torn down. 

This was for a logout call, and it worked pretty well except in Safari
(it might work on safari now, I am not sure). Since it was only a
logout call and we had a timeout after 30 seconds anyway, it was not a
huge issue if it was not 100% successful. But in practice it works
pretty well.

It's one of those crazy ideas that you just do if you absolutely need
to. I think gmail might do the same thing for gchat; if you close a
gmail window you will notice a slight delay. I haven't looked at their
code though so I don't know for sure.

[flexcoders] Custom style for list items

[ozziegt]

I have a List and I would like to apply a specific style (font weight,
background color) to a couple of items. I am looking for the best way
to do this from a performance perspective...

Is there any way to do this without creating a custom item renderer?

I created an ActionScript item renderer based of ListItemRenderer, and
overrode the commitProperties() method to apply the appropriate style.
However, while bold works, using setStyle with backgroundColor isn't
working. Any ideas? Is this the best way to do it or should I just
create a custom item renderer in MXML based off HBox?

[flexcoders] Viewing server response from a FileReference.upload request?

information that I need.

[flexcoders] Detecting a drag drop reorder on a List

[ozziegt]

I have a List control and which allows drag  drop re-ordering. I need
to detect when someone uses drag  drop to re-order the list. Is there
an easy way to do this? 

Right now this is my solution:
1) OnDragStart, store the a copy of the list data. 
2) OnDragComplete, compare the stored copy to the current list and see
if anything changed.

This works pretty well but it doesn't seem like the best way to check
from a performance perspective. 

I can't use the change event for the data provider because that
doesn't have a re-order type...it fires two events: one for add and
one for remove. Not what I need.

Any ideas?

Thanks

[flexcoders] Error when PopupManager hides a popup in the middle of an effect

I have a popup with an addedEffect defined on it. It works great when
I call PopUpManager.addPopup, but if I click anyhere while the effect

is gone.

Any suggestions on what I can to do prevent this from happening?

[flexcoders] Re: Error when PopupManager hides a popup in the middle of an effect

[ozziegt]

The problem seems to be related to the sequence. If I remove the
sequence effect, I can't reproduce the bug anymore.

The bug happens when I remove the popup but add back it before the
sequence effect has time to complete.

My workaround for now is to just bypass the popupmanager, break up the
sequence into two parts, keep the popup on my stage at all times and
use the showEffect and hideEffect properties instead (FYI: using a
sequence in hideEffect also throws an error). For my particular
situation and use of this popup, it works out pretty well without any
additional code.

If a solution is ever found for this problem, I might go back to using
the popupmanager.

I am using the event so the MXML component knows when it has been

some event listeners appropriately. Perhaps this isn't the best way to
do it. If another way is better, I'm open to hear it. :)

Yes the currentTarget is the same as the target. However, it seems
that it is because it is somehow getting added 4 times and removed 3
times. I don't konw why...my code that calls addChild is only being

 You would listen to those events from the ViewStack, you will have a
