[flexcoders] How to create an overlay on top of a list/datagrid
I haven't been able to find any examples of this, which is frustrating, since I believe this should be an easy task. I want to display a canvas (or any other sprite) which simply places a gray overlay over the entire grid/list with some message in the middle. In java this would be as easy as using the component's glasspane, but I haven't been able to find anything similar. Can someone point me in the right direction? Thanks.

[flexcoders] Disabling grid does not disable column check box?
In a very conventional corporate app with View, Insert, Edit, Delete
modes, certain datagrids must be view only in Edit mode. It really
surprises me that on a datagrid, with editable=false, enabled=false,
selectable=false, the checkboxes in a grid column can still be clicked.
I am creating the checkboxes with:
mx:DataGridColumn id=dgcRmv headerText=Remove width=100
mx:itemRenderer
mx:Component
mx:CheckBox
selected={data.rmvDir == 'true'} paddingLeft=10
labelPlacement=right
change=outerDocument.cbRmvDirHandler(event)/
/mx:Component
/mx:itemRenderer
/mx:DataGridColumn
With everything turned off on the grid, the cb can be checked and the
handler runs. Appreciate a solution to this. TIA,
Mic.
[flexcoders] Re: Disabling grid does not disable column check box?
Just found I can stop it dead with an enabled=false on the cb itself:
mx:CheckBox
selected={data.rmvDir == 'true'} paddingLeft=10 enabled=false
but I cannot get to the checkbox with actionscript because Flex will not
let me give the checkbox an id to reference it with ...
mx:CheckBox id=cbRmv = id attribute is not allowed on the root tag of
a component ...
if the solution is me having to individually disable the 11 checkbox
columns on the 3 grids, how can I reference them? I suppose I could bind
i.e. enabled = {mode=='VIEW'} but curious on the AS reference,
TIA,
Mic.

[flexcoders] Variable Scope, Lifetime across pages
Hi, I ran into the following issue. I have a Flex application with multiple pages, and the navigation is done via a TabNavigator. Now if I navigate around, each mxml component within the Tab Navigator gets called. However, if I navigate away from page A, and come back later to it, the member variables are still instantiated and have all their values assigned. Is there a way to force Flex to reinstantiate the component each time it is called? I am having the problem because I come back with a different ID for this page, thus I need to refresh everything and reload new data, but I do not want to reset, and re-initialize all member variables manually. Thx, Martin

Re: [flexcoders] Re: Flex and .NET
Hi Steve, The dataset which I am using in my Flex app is being edited, with some records added or deleted or filtered. As I am doing this in the Flex application, the backend service (web service) does not know which have been modified, thus, I need to send back the current data I have in the Flex application. By the way, some updates on this. I tried to send the ArrayCollection as it is in .NET and I am getting the same as an ArrayList, which contains XML document tags. The only beef with this is that there is no actual tag for the field (column), so I have no idea which column to actually map back to the dataset. I am going to field portions of the data returned back tomorrow, as my codes are all in my office machine.

Good point. I suppose that you could throw in some regex to strip that

[flexcoders] Re: ArrayCollection to Delimited String
This is where using an ArrayCollection of ValueObjects (VO), comes in
handy. The VO class structure/type in the client maps to a class in the
web service. So when you pass the ArrayCollection, the web service
knows what the structure of the objects is, and can deal with them
appropriately. Take a look at WebOrb

that could help.

[flexcoders] Re: Flex and Reporting
Crystal Reports is great for generating data driven .Net reports. But, if you wanted to generate a wysiwyg type of report, that mirrors what the user sees in the flex app, you're going to run into a lot of problems. AlivePDF is good for simple client-side pdf report generation. However, IMHO, its not quite mature enough of a product yet, to be a robust solution for enterprise reporting. So, that leaves you with using a server-side solution, like Jasper reports of FOP (java), or bite the bullet and spring for LCDS or WebOrb. It's funny, most clients scream for high-fidelity PDF reporting. But, when they see the price tag for the last two solutions, they often choose to go without. There is a way to display a PDF in Air. For Flex, you might be able to hack some kind of iFrame solution, but I haven't heard of anyone that has pulled that off yet. -TH --- In flexcoders@yahoogroups.com, Angelo Anolin angelo_ano...@... wrote: Some updates on this.

[flexcoders] URL pound sign questions
Hello Everyone, I have 2 questions about the url pound sign: 1. Flex includes the pound symbol at the end of every URL (http://www.mysite.com/folder/#). Is it possible to remove the pound symbol (http://www.mysite.com/folder/)? 2. In a social networking site, could 'user' in the URL, www.socialsite.com/user, be parsed by Flex to display that user's profile? This does not seem possible but a client asked for it.

[flexcoders] Help with a RegExp
Hi,
I have a filter function for an array collection that I'm working with. In this
scenario, I start with an ID such as '1'. Based on that, I want to return
'1_1', '1_2', etc... Basically, an underscore followed by 1 digit.
Here's the code:
var currentID:String = item.id.toString(); // i.e. 1_1, 1_2, etc..
var testID:String = buttonID + '_'; // buttonID would equal 1
var pattern:RegExp = new RegExp('^' + testID + .);
if( pattern.exec( currentID ))
return true;
else
return false;
The problem is that this filter is also returning other IDs such as '1_1_2',
'1_1_3'. I thought the '.' would limit it 1 character only after the
underscore.
Can anyone see where I may be going wrong?
Thank you!

Hi,
I am using POST. In the simplest of terms, I'm trying to access a web
page that requires login with username and password. The client is not
exposing web services or a database port, but I can create a customized
PHP access page. The requirement is for a customer who downloads an
application to enter their username and password into the application
before the application unlocks itself. The application needs to connect
to the web site to check authorization, remember, no web service or
direct jdbc access.
So what I'm trying to accomplish, and maybe I'm just going about it
all the wrong way is : Access a web site from a remote location, provide
a username and password, receive an OK or FAIL.
What I've been trying to do is use a PHP form on the site. I can
manually browse to the page , type in the id/password and get directed
to an OK page. Can't seem to do this with HTTPService. Presumably I
should be able to do anything I can do with a browser client. so what am
I doing wrong?

If you click anywhere but the icon, the gridclick and itemclick events both
fire. But if you click on the icon, you get only the gridclick. And the
gridclick event doesn't get anything useful for target/currentTarget, as far
as I can tell.
The main thing I really want to do is have clicking on the icon select the
row, just like clicking anywhere else will do. Tangentially, it would be
nice to know how to capture the event in case I wanted to do something
different with clicking on the icon.

Re: [flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)
When you set the highlighted property on your items, they are
dispatching PropertyChangeEvents. The collection they are in will
receive these PropertyChangeEvents and dispatch CollectionChangeEvents.
The AdvancedDataGrid will receive these and perform a visual update,
which appears to clear the rollover highlight.
To prevent the rollover highlight clearing you need to avoid dispatching
PropertyChangeEvents when you update the hightlighted property. Which
means you need to use a custom event in your binding (see below). This
should fix the choppiness without breaking the binding, although you
might want to rethink this whole approach: When you select an item in a
datagrid it sets the selectedItem property; it doesn't update the
underlying data items. Why not follow this pattern for tracking which
item is rolled over?

{
import flash.events.EventDispatcher;
public class TestObject extends EventDispatcher
{
[Bindable]
public var label:String;
private var _highlighted:Boolean;

_highlighted = highlighted;

[flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)
Nice Paul,
So, extend ADG and add a highlightedItem:MyItemVO property that uses a
Bindable highlightedChange event; with the same getter/setter
structure as below. Not sure, in MyADG, if you'd set the
highlightedItem on itemRollover or initialte from the itemRenderer, with
an Event though; just depends on how you can get to the data or
listData. But then change the exterior bindings to
myADG.highlightedItem. Sound about right Paul.

When you set the highlighted property on your items, they are
dispatching PropertyChangeEvents. The collection they are in will
receive these PropertyChangeEvents and dispatch
CollectionChangeEvents.
The AdvancedDataGrid will receive these and perform a visual update,
which appears to clear the rollover highlight.
To prevent the rollover highlight clearing you need to avoid
dispatching
PropertyChangeEvents when you update the hightlighted property. Which
means you need to use a custom event in your binding (see below). This
should fix the choppiness without breaking the binding, although you
might want to rethink this whole approach: When you select an item in
a
datagrid it sets the selectedItem property; it doesn't update the
underlying data items. Why not follow this pattern for tracking which
item is rolled over?
package
{
import flash.events.EventDispatcher;
public class TestObject extends EventDispatcher
{
[Bindable]
public var label:String;
private var _highlighted:Boolean;
public function get highlighted() : Boolean
{
return _highlighted;
}
[Bindable( event = highlightedChange )]
public function set highlighted( highlighted : Boolean ) : void
{
_highlighted = highlighted;
dispatchEvent( new Event( highlightedChange ) );
}
}
}

1) Yes, this works fine, for the display portion only. It doesn't
address
the actual problem of needing to set a flag in the data that
indicates it is
the currently highlighted one, that flag being also used by other
things
that bind to the data that don't want to know about UI details like
the
grid. In this case, I had a number of chart listeners that would
toggle
series on/off depending on which one was highlighted in the grid.
2) There is no commitProperties on AdvancedDataGridItemRenderer.
Perhaps
you meant validateProperties. In this example, it gets called only
when the
grid is first displayed and not when any item is
highlighted/de-highlighted
or selected/de-selected.
3) Yes, the styleFunction does get called when the highlighted
object
changes. But if you move the code to set data.highlighted there, you
get
the same result! It just seems like anything that changes this bound
variable on every repaint of the cell is doomed to break the
rollover
highlight.

[flexcoders] using addChild() or includeInLayout ?
Hi All, Is it better to create controls dynamically using addChild() or write the mxml for all the controls and use includeInLayout and visible property to show / hide the controls? Thanks Arpan Cricket on your mind? Visit the ultimate cricket website. Enter http://beta.cricket.yahoo.com
RE: [flexcoders] using addChild() or includeInLayout ?
You should get faster startup if you wait until you need them and create them dynamically. But I think the states feature is probably the best way to accomplish this.

Re: [flexcoders] Re: Flex and Reporting
Is FlashPaper still supported? Never actually used it, not quite sure how it works, just that it lets you view documents inside of Flash. 2009/6/10 Tim Hoff timh...@aol.com: Crystal Reports is great for generating data driven .Net reports. But, if you wanted to generate a wysiwyg type of report, that mirrors what the user sees in the flex app, you're going to run into a lot of problems. AlivePDF is good for simple client-side pdf report generation. However, IMHO, its not quite mature enough of a product yet, to be a robust solution for enterprise reporting. So, that leaves you with using a server-side solution, like Jasper reports of FOP (java), or bite the bullet and spring for LCDS or WebOrb. It's funny, most clients scream for high-fidelity PDF reporting. But, when they see the price tag for the last two solutions, they often choose to go without. There is a way to display a PDF in Air. For Flex, you might be able to hack some kind of iFrame solution, but I haven't heard of anyone that has pulled that off yet. -TH --- In flexcoders@yahoogroups.com, Angelo Anolin angelo_ano...@... wrote: Some updates on this. I was able to generate a Crystal Report for this where the Flex application opens up in another browser the PDF file which was generated by the report.
