Re: [flexcoders] Re: What's wrong in using itemRenderer ?

[Rishi Sahi]

Hi Amy,

Thanks..

One more question , Is there any different rule to add itemrender on
categorized grids ? For example, Here is my sample code to for Hazard and
Status column ,

var col1:AdvancedDataGridColumn = new AdvancedDataGridColumn();
var col2:AdvancedDataGridColumn = new
AdvancedDataGridColumn();
//data for column 1
col1.headerText="Hazard"
col1.dataField = "hazard";
col1.itemRenderer = new RenderCategory();
cols.push(col1);
//data for column 2
   col2.headerText="Status"
col2.dataField = "status";
col2.itemRenderer = new RenderCategory();
cols.push(col2);

But when I view my grid , It only applies to Status column ,

[image: 1.PNG]

But if I remove grouping , rendering applies to both the columns . However,
Hazard is not a grouping field, There is another grouping field "category" .

[flexcoders] Re: Null object error on test for null

[Sunil D]

Which line does the null pointer error occur on? 

Not that this is you problem, but I always check for null when casting with 
'as'.

Re: [flexcoders] How to get the width of the Itemrenderer in a List

[dorkie dork from dorktown]

Spark. If the item renderer item is outside of the Lists visible area then
it returns width or height 0 or sometimes index out of bounds errors. It
seems items aren't created if they haven't been scrolled into view yet and
if they have but they aren't in view currently then I think it's returning
width and height as 0. I've made sure to set useVirtualLayout false.



I don't have the columnWidth or list height set but I have the ItemRenderer
width and height set to 32.

Re: [flexcoders] HTTPService not updating...

[dorkie dork from dorktown]

it's prob accessing it from the cache.

instead of this,
url="reports/xml/{_reportInfo.fileName}.xml"

use this:
url="reports/xml/{_reportInfo.fileName}.xml?time={getTimer()}"

that snippet might not be bindable so add the time in code whenever you
access that file

Re: [flexcoders] HTTPService not updating...

[Jake Churchill]

It might be getting cached.  Try adding a timestamp to the end of the url 
(ie url/myfile.xml?timestamp={currentTimeStamp} ).

Before you all the .send() method, reset the timestamp variable to the current 
time.

Well, in the toolbox the are labels for the components.I want to drag 
the label and drop the component.After that i want to double click the 
component to show an alert.

The Application:

xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"

xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" width="100" height="100">





























It drops only the labels and the double click doesn't work.
any ideas?

Assuming you want to set it for all text areas, you could experiment

[flexcoders] How to get the width of the Itemrenderer in a List

[dorkie dork from dorktown]

How would I get the width of an item renderer in a list?

I'm trying to fit the width of a list so that it doesn't clip an item
renderer half way thru if there's not enough space. So if the List is 105 px
wide and an single itemrenderer is 10 pixels wide then I want to resize the
list to 100 pixels so item 11 doesn't show.

Re: [flexcoders] Why can't I change the highlight color of Spark text?

[dorkie dork from dorktown]

Thanks. It was working all along. I was using textarea.selectRange(). Since
I was pressing a button to select the text the textarea was always
"unfocused" so I wasn't seeing the effect of that style. I
added unfocusedTextSelectionColor as well.

[flexcoders] Possible to filter data by Type for LineChart series?

[eb]

All of the data examples I see for Flex charting are simply string months and 
number attributes, but that doesn't mesh with normal query results. Let's say 
this is my dataset from a query (returns all my withdrawals for the month). 

//my data
var expensesAC:ArrayCollection = new ArrayCollection( [
 { date: "1/12/10", type: 'checking', Amount: 450 },
 { date: "1/13/10", type: 'savings', Amount: 600 },
 { date: "1/15/10", type: 'checking', Amount: 300 },
 { date: "1/19/10", type: 'savings', Amount: 900 },
 { date: "1/20/10", type: 'checking', Amount: 500 } ]);

I'd like to have a 2-line chart...1 line for checking and 1 line for savings, 
but no lines appear. I tried implementing a dataFunction and debugging shows 
it's returns values at the correct type, but that doesn't work (no lines 
appear). Any ideas?
  
Here's the full mxml...if you remove the dataFunction attribute from the 2 
LineSeries, then the map (as expected) draws both lines on top of each other. 
Thanks in advance.

There is no “eval” in actionscript.  To pass XMLLIst a string it would have to 
be a string that can be converted to XML, not something that references

Not that I know of.  You could avoid all of this by just listening for the 
DataGrid's itemClick event. (mx.events.ListEvent)  In the result handler you 
could check if ( event.itemRenderer is btnRenderer ) { do your thing }

[flexcoders] Null object error on test for null

[Tom McNeer]

In the function below, I begin by testing to see if a particular object is
null (the array of ComboBoxes that represent the children of a Repeater,
which may or may not exist). The element is defined in MXML, though of
course it may be null.

But if it *is *null, a null object reference error is thrown. Could someone
please explain this for me? (SDK 3.5, by the way).

Would it be possible to simply add it to the MXML file where I am declaring the

Hi Angelo,

You're close.  You'll need to declare the event in the DataGrid.  A simple 
subclass should do the trick.  This way you can add the event listener in mxml 
too:

package myPackage

[flexcoders] Re: Detecting List width from its itemRenderer

[Alexander]

Hello again,

I thought I've found a solution by using 
the List's resize event to change the size 
of its items, but while it works for the 
simple test case listed below, it goes 
into endless loop in my real app with more 
complex layout and I see the traces:

resize list: 0 -> 480
resize list: 480 -> 480
resize list: 480 -> 464
resize list: 464 -> 464
resize list: 464 -> 480
resize list: 480 -> 480
resize list: 480 -> 464
resize list: 464 -> 464
...


TestCase.mxml:


http://www.adobe.com/2006/mxml";>











RowRenderer.mxml:


http://www.adobe.com/2006/mxml"; 
  width="100%" height="100%"

[flexcoders] Re: Method for a Datagrid Button Itemrenderer

[turbo_vb]

Hi Angelo,
You're close.  You'll need to declare the event in the DataGrid.  A
simple subclass should do the trick.  This way you can add the event
listener in mxml too:

package myPackage

{

import mx.controls.DataGrid;




[Event( name="myTest", type="flash.events.Event" )]




public class MyDataGrid extends DataGrid

{




}

}

[flexcoders] Accessing Network Drive in AIR

[sdl1326]

I have created an AIR application that accesses files on the network
drive. Each machine that is running the AIR app may have a different
letter/drive mapped to the network drive. Therefore, in order to
alleviate drive mapping issues, I wanted to simply use the absolute
network path to the file(s), i.e.




\\network-drive-location\department folder\config.xml




However, that doesn't seem to work as it consistently throws an error.
Is is possible to load files using this type of path or do I need to
have a letter associated with the path, i.e.




N:\network-drive-location\department folder\config.xml






Thanks for the assistance.

Re: [flexcoders] Re: Method for a Datagrid Button Itemrenderer

[Angelo Anolin]

I have written the following scripts, and yet this does not seem to work.

in my MXML file (main)

private function myDataGrid_CreationComplete() :void
{
  myDataGrid.addEventListener('myTest', myTesting);
}

private function myTesting() :void
{
  Alert.show('This event should have been called!');
}


in my datagrid, i have declared
creationComplete="myDataGrid_CreationComplete()"

In my itemrenderer, I have placed a code :

override protected function clickHandler(event:MouseEvent) :void
{
  dispatchEvent(new Event('myTest', true));
}

For some reason, this does not seem to work. From what I have read mostly, this 
should be able to do the trick.

Any input and ideas appreciated. Thanks..

So I declare my MXML like:

Re: [flexcoders] Method for a Datagrid Button Itemrenderer

[Angelo Anolin]

I know someone has encountered this before. 

Better to rephrase this one I guess.

I have an MXML file, where I have a method.  In that MXML file, I have a 
datagrid, where one of the columns, I created an external itemrenderer.  The 
itemrenderer is a button.  When I click that button, I want that button to call 
the method in the MXML file (so that I could re-use the button on other 
datagrids).

Hi Flexcoders,

I have a datagrid and an button itemrenderer named btnRenderer.as

I have set this button as an itemRenderer in one of my datagrid columns.



I need to respond to an click event on button, passing some of the value from 
the dataProvider attached to the datagrid.

Should I place my codes on the mxml file where my datagrid is declared?  How 
would the btnRenderer know that the method is called?

Thanks.

[flexcoders] Re: Push verse Poll in Flash Player

[Alexander]

I think it's worth trying, because trying to read
an integer this way won't waste any CPU cycles -
Flash/Flex probably run select() or poll() internally
and just sleep - until anything arrives over the socket.

(Versus trying to pull anything every 30 seconds -
that will cost you CPU and also feel delayed).

And whenever an integer arrives, then you could
use that number to indicate how many records have 
changed at your backend, so that you can use it to 
provide feedback on the progress to the user
while fetching the updated data over HTTP.
