I'm using Ubuntu as my OS, and Ganymede for my Eclipse version with Flash Player 10 release version. (I can't seem to install Flash 10 Debug Players, does anyone know how to do that on Ubuntu?) When I try to compile my application, it launches fine (when i Run it, not when I Debug it. Debugging doesn't work because I don't have a debug player installed.) However, I'm getting nothing when it runs, just a big blue application that does nothing. I can't visually add anything to the display list, I can't log anything out to Arthropod, I basically can't do anything. When I try to embed my application via SWFObject, that's no working either. I get the alternative content every time. Now here are my questions, I'm going to try and discover the answers ASAP for them, but if you know anything, could you help me out? Does FlexBuilder for Linux need to be installed on a Europa release? Does FlexBuilder for Linux require you to use Flash Player 9 release and debug players?

[flexcoders] ItemRenderer's style is changed when scrolling DataGrid
hi everyone, i wrote a renderer which extends DataGridItemRenderer in
DataGrid
some code below:
override public function getTextStyles():TextFormat
{
if (!listData||this.text==)
{
return super.getTextStyles();
}
if(listData.uid != lastUID)
{
var tf:TextFormat = super.getTextStyles();
if(data is PositionDataBottomInfo)
{
tf.bold = true;
}
else
{
tf.bold = false;
}
}
return tf;
}
if i don't operate the DataGrid, every row's style is correct. however ,
when i scroll the DataGrid, the row's style is incorrect.
after scrolling some rows turn bold, some turn normal.

if u want to listen a ArrayCollection when some of its elements are

Subject: [flexcoders] appending to a dataprovider in actionscript
I am still trying to iron out the problems with data binding in actionscript an
server push. If I just replace the old
array with a new one, it updates ok, but when I append to an array, it doesn't
seem to work.
I have to do everything in actionscript. I set up the data binding like this.
BindingUtils. bindProperty( lineSeries, dataProvider , ser, pointList) ;
Here is the way I'm currently trying to append the new data and catch the
error, but this does not work.
// oldArray is the same as pointlist from the data binding line of code above
for (var i:int = 0; inewArray.length; i++) {
oldArray.addItem( newArray. getItemAt( i));
}
What's more, because the app is fired remotedly from a server process, I can't
trace or run it in debug mode to find
out why it's failing. Usually, I'll throw in an Alert.show to find out if the
data is messed up or a variable is null, but
when I do it after running this loop, the Alert just hangs the whole
application. Is there anyway to throw an error to
a popup box (flash seems to do this from time to time on its own)
And one final related question. If I do get the new arrays to work, will the
charts labels and range adjust
accordingly. In other words, if the original array was from Mon-Wed, if the
new data is on Thurs, will the chart auto
adjust properly to show the new data?

You can optimize the itemRenderers by using UIComponent; see Alex's blog. And depending on how many items are in the dataProvider, you could see performance issues there as well. If you are performing any calculations you might look at ways to tighten up the code. With a one second refresh, you might be asking too much of the UI. -TH --- In [EMAIL PROTECTED] ups.com, Fu Di [EMAIL PROTECTED] wrote: hi everyone, i used dataGrid to display a list of real time data. when i finished it, i found it is slow. the DataGrid has 13 DataGridColumns, every column almost nest a ItemRenderer. i had to do this to meet the requirements of pattern. the data update every second, and i need to change the components¢ style in some columns following the data. as i know these two aspects will cost large calculation. who konws how to optimize it or other ways to achieve. thanks
