[flexcoders] Re: Datagrid sort order: is there a natsort() such as in PHP?
You have to do a sortCompareFunction, ala
mx:DataGridColumn dataField=number
sortCompareFunction={sortOnNumber} /
and then create something like:
private function sortOnNumber( obj1:Object, obj2:Object ):int
{
if( obj1[number] obj2[number] ) {
return -1;
}
else if( obj1[number]
obj2[number] ) {
return 1;
}
else {
// They are equal so do
another col sort if you want
if( obj1[ID] obj2[ID] ) {
return -1;
}
else if( obj1[ID]
obj2[ID] ) {
return 1;
}
else {
return 0;
}
}
}

This is sort order on some strings:
1
10
11
2
21
23
This natsort order on the same strings:
1
2
10
11
21
23
In short, it deals sanely with a numeric string suffix. Anything like
that in Flash/Flex out-of-the-box?

[flexcoders] Re: How to set the datetime format in datagrid?
One way to display a human readable date in a datagrid and have it be
sortable, is to use labelFunction={convertDate} and have the server
send over unix milliseconds. This is important if you want to be able
to properly sort the column.
A sample function looks like:
private function convertDate(item:Object, column:DataGridColumn):String {
var myDate:Date = new Date(item.Date);
var months:Array = new Array();
months = [, Jan, Feb, Mar, Apr, May, Jun, Jul,
Aug, Sep, Oct, Nov, Dec];
var a:Array = new Array();
var b:Array = new Array();
a.push(myDate.getMonth());
a.push(myDate.getUTCDate());
a.push(myDate.getUTCFullYear());
b.push(myDate.getUTCHours());
b.push(myDate.getUTCMinutes());
if (b[0]10) { b[0] = 0 + b[0] }
if (b[1]10) { b[1] = 0 + b[1] }
return months[parseInt(a[0])+1] + + a[1] + + b.join(:);
} }

[flexcoders] Re: Dynamically generated DataGrids having troubles with column width
I recall having to play around with this when I did this in the past,
just from memory I would suggest you try setting widths after you set
grid.columns by doing grid.columns[0].width = 100, etc. I think it
also would not work exactly if the total widths did not match the
grid, so you could try leaving the last one's width blank so it
auto-sets and see if that makes a difference.

You need to move your code that sets the label:

into the doShow() routine since that is where the objects get (re)set

[flexcoders] DataGrid setting selectedIndex causes text colors to change
Hi all,
I am building out a datagrid in AS, and the mx piece is:
mx:DataGrid id=tables dataProvider={gridData}
change=selectTable(event) sortableColumns=true width=100%
height=100% /
Now, when I create the grid, everything shows up great but at the end
of the populating the grid code I have a tables.selectedIndex = 3;
for setting a row by default.
This indeed selects that row, but the text in that row is WHITE now
instead of black! As I click/select other rows, the text there is
fine, but the initially selected row stays white no matter what.
Seems like a bug?

[flexcoders] Loading image and handling IOErrorEvent
Hi, I am loading in images in a loop as follows: imgs[j] = new Image(); pict = new Loader(); url = http://mydomain.com/images/test; + j + .jpg; preq = new URLRequest(url); pict.load(preq); imgs[j].addChild(pict); and if I close my browser or navigate away during a load, I get a popup from Flash saying Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed. Now, I read another thread and tried using try-catch and also: pict.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler); but these do not help. Also, I think the IOErrorEvent is for URLLoader, NOT just the standard Loader. The problem there is that URLLoader doesn't return something I can use as an image and causes a fault when adding it as a child to an Image. So, can someone tell me how to use URLLoader to load an image so that I can properly use IOErrorEvent? Thanks!!!

[flexcoders] passing variables to Timer handler routine
Hi all,
If I have an action (like putting up an alert popup, adding a child to
the canvas, etc) that needs to be delayed, it would be great to have a
good old sleep or something prior to the command, but I guess one
has to use Timers.
But since Timer calls a new function, how to best pass along any
objects or strings that it will need, other than have these as global
vars?
I tried something like this, but I can't reference the target as
shown, and you can't pass anything to the resetAlert from the listener.
function myAlert():void{
var test:String=testing;
var alertTimer:Timer = new Timer(3000,1);
alertTimer.addEventListener(TimerEvent.TIMER,resetAlert,false,0,true);
alertTimer.start();
}
function resetAlert(e:TimerEvent) {
trace(traced test:+e.target.test);
}
I know it is something easy I'm missing, so thanks!
