[flexcoders] Bug in ADG?, possible to bind labelFunction to editor with no dataField?
Hi,
Does anyone have any idea how to edit data that does not come from
fixed object properties i.e. myObject.Name but myObject.Attributes[2]
which might be name?
I have a 2D array, array of rows and array of cells for each row, both
are arbitrary. I have this successfully displayed my data in
AdvancedDataGrid via labelFunction.
public function getContentLabel(item:GridRow,
column:CustomLabelColumn) : String
{
if(item != null)
{
return item.Cells.getGridLabelCellAt(column.columnIndex).Label;
}
else
{
return null;
}
}
How do I edit the data in these columns?
I looked at
http://www.adobe.com/livedocs/flex/3/html/help.html?content=celleditor_8.html#197235
and tried messing around with itemEditBegin and itemEditEnd. I have
itemEditBegin working successfully where I am able to display my label
in a text box. The itemEditEnd for ADG seems to crash because I'm
using typed objects instead of plan strings or XML.
In fact I'm convinced there is a bug in the itemEnd base handler. I
tried calling preventDefault from the grids itemEnd function but no
luck, I am forced to overwrite the event.reason so that the base class
doesnt destroy my itemEditor.
My issue is here:
In AdvancedDataGridBaseEx.as
private function
itemEditorItemEditEndHandler(event:AdvancedDataGridEvent):void
...
var newData:Object =
itemEditorInstance[_columns[event.columnIndex].editorDataField];
var property:String = _columns[event.columnIndex].dataField;
var data:Object = event.itemRenderer.data;
var typeInfo:String = ;
//WHY is this only XML??? my data variable has plan String text and
yet I never make it into the typeInfo == String part since typeInfo is
because the XML loop never executes on an object;
for each(var variable:XML in describeType(data).variable)
{
if (property == variab...@name.tostring())
{
typeInfo = variab...@type.tostring();
break;
}
}
if (typeInfo == String)
{
//NEVER make it here
if (!(newData is String))
newData = newData.toString();
}
//..
//CRASH HERE since property is null.
// data = Some Text;
if (data[property] != newData)
{
bChanged = true;
data[property] = newData;
}
Re: [flexcoders] Common base class for components
Hi Jules,
Object Oriented programming in my mind is about making use of references
to objects. With this in mind, here is a way I use to centralise common
functionality (functions) that I can access throughout my application:
1. Create an object in the Application mxml file - this will be
referenced throughout your application components
eg: objApp:Object = new Object();
2. Create functions inside a script block in the Application mxml file
eg:
public function myUsefulFunction(): void {
...
}
3. Add references to my functions to objApp object - no () after the
function name as it is a reference to it, not a call to it
eg: objApp.myUsefulFunction = myUsefulFunction;
I can also include function classes here and make reference to their
functions
4. Pass objApp as a reference to each component - I must be sure that
the deepest component is chained back to the Application mxml by passing
this reference through all its parents
eg: comp:mypanel id= objApp={objApp} /
5. Inside each component, bind objApp
eg:
[Bindable]
public var objApp:Object;
6. Call my functions from whereever I want to, from any component that
has a reference to objApp
eg: objApp.myUsefulFunction();
7. I am not just limited to passing references to functions this way
either. I can pass references to child objects and even move them
around the stage, etc. also
eg: objApp.myPanel.x = objApp.myOtherPanel.x + objApp.myOtherPanel.width
+ 10;
Hope this helps you. Works really well for me. It seems a very easy
way to use the power of object oriented referencing to talk to anything,
anywhere in an application. And if I ever want to know anything about
any object, I can usually query it via reference to objApp.
Could call it the objApp framework if it hasn't already got a name :o)
Cheers,
Martyn

Hi list, anyone know if it's possible to have all our
components inherit from a common base component of our own
making?
There are some things in our app that every View component
will have to do at loadtime, and it'd be nice to just
write that code once and have all the other components
inherit it...
Last time I checked in Flex 3 Beta 2 there was some vague
suggestion of using Template Components, but that seemed
like an afterthought in the SDK at the time. Just thought
I'd check to see if you knew of any tricks for doing it :)
RE: [flexcoders] Silent Print from Flex on Kiosk
Yeah, The Flash Player doesn’t allow silent printing, as some wag would write

Nate is right, if you have JS code that works, call out to that, or use some
other means of interacting with the printer (we have a client side DotNet
component to handle our printing needs).

Your solution is very good if the event handler in MXML file. I
correct my code follow you and have good result.
But I have only special case, the event handler in AS class
My code in main.mxml

showCommand.addEventListener(Event.SELECT,

So the error display when I click show menuitem in taskbar

RE: [flexcoders] RE: ItemEditors and rowHeight
You can say that again ;) Wading through 24.5k lines of code is somewhat turgid... I played around with the y offset (seeing the editor is taller than the renderer) but it sits the editor on top of the grid rather than in it, which looks more than a little bit funky. It appears the main issue is that the grid doesn't re-do the layout when an editor is added, which I'll assume is for performance reasons rather than a bug! I'll have some fun today hacking up the ADG and see if I can't make something happen, if not well time to re-think the UI ;) Gk.

RE: [flexcoders] dynamic context menu problem
The solution I put in place for a similar problem... Add some javascript to eat the right click event (so the default menu isn't shown), and have it dispatch an event to the application. The application then dispatches a RIGHT_CLICK event having it bubble. Any UI component listening for that event captures is and prevents it from bubbling further (You want to let it get to the topmost point in the display list, and catch it on the way back down). That UI component opens up the menu you've set up for it. Gk.

RE: [flexcoders] BindingUtils and ResourceManager Question
Thanks for the suggestions, Johannes. Unfortunately, using an explicit
event won't scale well in a big application since every access of a
resource string from ActionScript will require this treatment.
I've done a -keep-generated-actionscript and tried to grok the
ActionScript code the Flex compiler generates when specifying a data
binding in MXML and it just doesn't make sense to me just yet.
I'm still on the hunt for a code sample using a ChangeWatcher or some
means to set up the binding without explicit events. My objective is a
single line of code just like using BindingUtils.bindProperty. It seems
like I should be able to write a similar class as BindingUtils and
expose an API that takes a Function as the chain property, instead of an
Object.
Anyway, thanks for your suggestion.

Subject: Re: [flexcoders] BindingUtils and ResourceManager Question
on rereading your post i realise that what you are after is change
events (but my post will also help a bit me thinks)
a few people did custom annotations which function like an event
listener, just google a bit, i think it will make your life easier.
old post///
ok, i will approach it slightly differently.
I would use a presentation model to bind the text to,
so
component
control text=presModel.someText/
/component
in my pres model
class presModel
{
[Bindable(localChange)]
[Bindable (someTextChange)]
public function get someText():String
[Bindable(localChange)]
[Bindable (someOtherTextChange)]
public function get someOtherText():String
}
this way you have groups of text that update at the same time when your
local changes (which in the workflow we use would look something like
this (still inside this presModel)
[Trigger (path=myModel.theLocalleValueIWantToKnowAbout)]
public function set localle(localle:String)
{
dispatchEvent(localChange)
}
where this localChange event will update all the strings which have a
bindable declared with that custom event name.
the trigger annotation is basically an event listener and is the same as
saying
in my local presentation model notify me when the applications localle
changes,
thus someAppModel.addEventListener(localChange)

Having just localized a medium sized application into Spanish, I
ran into a recurring pattern I had to work around that I really
shouldn't have to, specifically around data binding localized resources
from ActionScript.
For example, in MXML, one can data bind a localized resource and
when the localeChain is switched dynamically, all bound clients will
requery their values and the new language will display:
mx:Label text={resourceManager.getString(ResourceEnums.COMMON,
'labelAppointments}/
When the localeChain is switched, the label above will
automatically update to the Spanish version, just like magic. This is a
very cool feature of Flex 3 resource management.
However, there are many use cases where I need to bind to
resource bundles from within ActionScript, sort of like this:
public class Foo
{
[Bindable]
public var bar:String;
public function Foo()
{
bar = ResourceManager.getString(ResourceEnums.COMMON,
'labelAppointments');
}
}
When the localeChain is updated, bar is obviously not
automatically updated because bar is not bound to the resource, it is
just a simple assignment.
BindingUtil.bindProperty and bindSetter don't appear to offer
parameters that will work with ResourceManager. I've experimented a
little, but it does not appear possible to use BindingUtils to bind to a
resource.
I had to work around this by listening for a localeChange event
and then reassigning the resource to the variable. This does not scale.
So my question is simple: can you bind a variable to a resource
in ActionScript? If so, how?
Thanks!

RE: [flexcoders] BindingUtils and ResourceManager Question
HI Yves:
This is a great suggestion! It's pretty readable and doesn't require
changes anywhere else but where you instantiate the property.
I will write a class to manage this, though we can't refactor our MXML
(way too much code) to use the same mechanism. This will just be for
those use cases where we need to bind in ActionScript which is
fortunately a pretty small percentage.
Thank you!

What we have done is to separate ourselves from the resource manager a
bit. We have created a new class that basically has a bindable property
called value. This class is passed the name of the string that is
localized in the resource manager and hooks to the resource manager. It
monitor for changes on the resource manager and when they are detected,
the class sends an event that triggers the binding. So, it can be used
directly in MXML or in the .as file by using the BindingUtils class.
In pseudo code (.as file):
var localizedProp:LocalizedProperty = LocalizedProperty.create(Bundle,
localized property);
BindingUtils.bindProperty( this, your variable, localizedProp,
value);
In pseudo code (.mxml file):
[Bindable] var localizedProp:LocalizedProperty =
LocalizedProperty.create(Bundle, localized property);
mx:label text={localizedProp.value}/

Re: [flexcoders] Reducing white space in charts
I had the same problem, and wasn't about to get it completely eliminated. I used the following styles on my AxisRenderer for both the horizontal and vertical axes: showLabels: false; showLine: false; tickPlacement: none; minorTickPlacement: none; axisStroke: ClassReference(Stroke); I did this in code, but it should be possible via CSS too, although my experience with CSS is that it isn't very reliable. Note that I didn't want the axis appearing at all - if you do, you will have to adjust the styles. If you're still stuck, I suggest you look in the Flex source code, at the AxisRenderer.as file to see how it renders the axisrenderer, and then change it. The chart classes might help too. 2009/1/30 Vik S.

Hi everyone, I created an animated pie chart that is divided into 3
segments.

field=field
mx:showDataEffect
mx:SeriesInterpola te/
/mx:showDataEffect
/mx:PieSeries
/mx:series
/mx:PieChart
The pie animates perfectly but when new data comes in, if the new
data has only data for 2 out of the 3 segments, it will animate
correctly and display the sections correctly but the old data from
the 3rd section remains as if it's cached somehow. If I minimize IE
and then restore it, the old data disappears as if the page
refreshes... Is there a way to automatically refresh the page still
animating the pie charts. If I remove the animation I do not have
this problem.
Thanks.

Hi Jules,
Object Oriented programming in my mind is about making use of

common
functionality (functions) that I can access throughout my

1. Create an object in the Application mxml file - this will be
referenced throughout your application components
eg: objApp:Object = new Object();
2. Create functions inside a script block in the Application mxml
file
eg:
public function myUsefulFunction(): void {
...
}
3. Add references to my functions to objApp object - no () after
the
function name as it is a reference to it, not a call to it
eg: objApp.myUsefulFunction = myUsefulFunction;
I can also include function classes here and make reference to
their
functions
4. Pass objApp as a reference to each component - I must be sure
that
the deepest component is chained back to the Application mxml by
passing
this reference through all its parents
eg: comp:mypanel id= objApp={objApp} /
5. Inside each component, bind objApp

[flexcoders] [flexcoder] RemoteClass + ArrayCollection question
Right now I'm playing around with the RemoteClass feature with a few
ActionScript classes. What I've noticed is that if I have a single object I
can nest AS classes. So if I have two AS classes foo and bar I can have the
following work
[RemoteClass(alias=com.ca.foo.Foo)]
public class foo
{
public var ID:int;
public something:bar;
}
this gets converted correctly when I call a function that returns a foo.
bar is correctly identified as a bar and is placed as such.
Now here's where I've run into trouble. If I try to have an array of bars I
can't figure out how to get this to work correctly. Example:
[RemoteClass(alias=com.ca.foo.Foo)]
public class foo
{
public var ID:int
[ArrayElementType(MenuItemSetting)]
public something:ArrayCollection;
}
This does not work. When I return from the remoteObject call foo is done
correctly up to the ArrayCollection. The ArrayCollection has objects in it
instead of MenuItemSettings.
Here is the result function that has objects for the ArrayCollection Items
public function Success(event:ResultEvent):void
{
var test:foo;
if(event.result != null)
{
test = MenuItemPackage(event.result);
}
}
However, here's where it utterly baffles me. In my result function if I add
this one line of code to it, the objects for all items in the collection
become type bar.
public function Success(event:ResultEvent):void
{
var test:foo;
bar(event.result.something[0]);
if(event.result != null)
{
test = foo(event.result);
}
}
I do realize this will have issues if there are no elements in the
ArrayCollection or if the result is null. What the heck is happing here? I
can even put the breakpoint in before the bar(event.result.something[0]);
and look at result and it is typed to the bar.
My other question is, can this be done automatically? Or do I need to leave
in the bar(event.result.something[0]);?
Thanks for the help.
[flexcoders] How to encode query parameters?
Hi All, Every service call to my server requires query params (POST and GET), even some POST requests will send query params. I have found that with HTTPService if I specify the Object with key value pairs in send( queryParams) it does not send the xml I set as the data property. Some of my query params need encoding but I cant seem to find a urlencode(str) in Flex 3 SDK like in JavaScript. Does anyone know how I can encode a string for a query param? Any help much appreciated. Greg

[flexcoders] Is there a best-practice for knowing when a component is being shown to the user
Hello, imagine an application composed of a nested hierarchy of Components, ViewStacks, View States, Navigators, etc. How can a component on the bottom of the hierarchy run a function every time he is shown to the user? The show event is only dispatched when the component visibility changes to true. If we are changing the component's parent visibility, the component might not be visible on screen, but the event is never dispatched. So, this means that a component never knows if it is being shown to the user or not (really visible!). This is a huge problem, since until now I wasn't able to find a clean an unobtrusive solution. Is there a best-practice for solving this problem? Thanks, João Saleiro

I found that using the flash component kit's UIMovieClip, which doesn't include the standard invalidation methods, was a real eye opener to show me why the framework works as it does. HTH; Amy

I do realize this will have issues if there are no elements in the

can even put the breakpoint in before the bar(event.result.something

and look at result and it is typed to the bar.
My other question is, can this be done automatically? Or do I need
to leave

I'd be inclined to guess that the only hard reference to bar in the

bar(event.result.something[0]);
Try doing this:

RE: [flexcoders] itemRenderer data question (recycling)
As you say, use the right tool for the job. But only the person doing the job is in a position to select his tools. And a couple followups, for the benefit of anyone coming across this thread in the future: 1. Recycling is implemented for performance reasons. If your dataset is small, then recycling can be a negative,as the original poster has discovered. Repeater allows recycling if desired. 2. If you are having difficulty with events from repeated content, it is probably because you are using declarative mxml to build your repeated content. Instead, repeat a custom component. You can declare metadata events, and assign a handler directly in the mxml. Events are actually easier with repeated content than with itemRenderers, particularly if you are uncomfortable with bubbling events, as some are.

RE: [flexcoders] checkbox itemEditor in DataGrid
Have the renderer dispatch a bubbling event on change of the checkbox.
In the handler, you can access the item, and get the item index and the
checked state. Use that to set the selectedIndex on the DataGrid.
Of course the usual itemRenderer recycling caveats apply.

RE: [flexcoders] Re: Login/Registration Page ?
The process of logging in, getting authenticated and then staying authenticated for subsequent data service calls is a common requirement, and there are few examples. I suspect it is because there are many parts to the process and thus very many possible solutions. For example, in the links valdhor posted, one talks to PHB via remoteObject through WebOrb. One uses HTTPService to talk to Cold Fusion. And that is not even considering the options available withing Flex: Singleton data model? XML? ArrayCollection? ViewStack? States? Pop-up? So here is one more approach. Note, I am not a security expert, and cannot vouch for the level of security this provides. Any security folks out there are welcome to suggest alternatives. Note, a discussion of OOP coupling principles will not be helpful in this context. Flex: * Pop-Up prompts for User id and password, calls function on the main app, passing the values. * The main app hashes the password(MD5 library available), and sends credentials to server Via WebService. Dot.net: * WebService login method validates the credentials against a database. * If valid user, generates a session Id string, puts in a HashTable, and returns the sessionId and any other user info needed * If not valid an error node is generated and returned Flex: * A result handler examines the returned XML. If an error node then a message is displayed in the still visible pop-up, permitting retry. * If user is authenticated, a User object in a data model is populated, and the Login popup is closed. * All subsequent calls to the dot.net webservice include the session id. Dot net: * All calls, except for login, authorize the call by checking the session id in the hashtable. * If session id is found, a timestamp is checked for timeout. * If session has timed out, an error node is returned to the Flex client * Otherwise the call continuse to retrun the requested processing/data. * All returned data is wrapped in a known structure XML node, so it can be procesed properly in the Flex result handler.

It does change the bg color in the wrapper. The behavior you talk about can
happen if you use
'backgroundGradientColors' because the bg color of the wrapper is set from
the 'backgroundColor' property, so even if you use gradient colors for the
bg of the flex app, you should still set 'backgroundColor' for the bg color

RE: [flexcoders] Bug in ADG?, possible to bind labelFunction to editor with no dataField?
If you know that var data:Object = event.itemRenderer.data; contains a
string, why not just use toString() to put the string value in a string
variable?:
And I am not quite following you otherwise. What are you truing to do
with describeType()? That is usually used with non-dynamic objects, but
you have a simple 2d indexed array, correct? You said, array of rows
and array of cells. Do you mean array or do you mean you have nested
dynamic objects?
If you have nested dynamic ovjects, you can examine them with a for-each
or for-in loop.
Note, describeType is costly. That means slow, so be sure you need
it. It seems like a dangerous thing to do in a lableFunction.

Hi,
Does anyone have any idea how to edit data that does not come from

which might be name?
I have a 2D array, array of rows and array of cells for each row, both
are arbitrary. I have this successfully displayed my data in

}

How do I edit the data in these columns?

and tried messing around with itemEditBegin and itemEditEnd. I have
itemEditBegin working successfully where I am able to display my label
in a text box. The itemEditEnd for ADG seems to crash because I'm
using typed objects instead of plan strings or XML.
In fact I'm convinced there is a bug in the itemEnd base handler. I
tried calling preventDefault from the grids itemEnd function but no
luck, I am forced to overwrite the event.reason so that the base class
doesnt destroy my itemEditor.
My issue is here:
In AdvancedDataGridBaseEx.as

var newData:Object =
itemEditorInstance[_columns[event.columnIndex].editorDataField];
var property:String = _columns[event.columnIndex].dataField;
var data:Object = event.itemRenderer.data;
var typeInfo:String = ;
//WHY is this only XML??? my data variable has plan String text and

Hi,
One way is to use File instead of FileReference. You can get the
ByteArray that way and pass that to your service. the only caveat is
that you won't be able to track the upload progress; unless you do

RE: [flexcoders] Re: checkbox itemEditor in DataGrid
The safest way would be to loop over the dataProvider, checking the value of the property that drives the checkbox state, and build an array of indexes that are checked. Then assign that to the data grids selectedIndices property, If you could be sure to never get off, you could manipulate the selectedIndices array directly.

RE: [flexcoders] Re: checkbox itemEditor in DataGrid
In the event handler, you can access the itemRenderer through the target or currentTarget properties. From there you can get at the data item object and thus get the index of the item(see the Collection api for the exact method). But better to loop over the dataProvider and check the selected property every time.

[flexcoders] drag and drop ('into' the list items, while not adding to the list itself; Ex: iTunes)
Hello All. I've run into a problem, need other perspective(s)/solutions: Simply put: I want to implement drag and drop, like iTunes, in an AIR app. Seems easy, but...this particular scenario is puzzling. Right now, just like iTunes, I have two list-based controls (both are populated from collections of data within SQLite), one is a DataGrid and one is a List. Dragging and dropping from the Grid to the List is simple, yes, but I would like to drop on the list item's label/text/name in the List and perform another function (specifically an update to SQLite) and NOT simply drop the item and append to the list. Follow? As in iTunes, you can drag a song into a folder and it adds the song into the folder. (I would make that reference in SQLite in this case). It doesn't make a new folder by appending (wrongly) the dropped song to the folder list. (Which is what I have now: If I drag a item from the grid and drop it on the list, it's appended to the list, but I want it to become a value within the list item (pseudo nested) not a value in the list itself.) Is there a simple solution here I'm not seeing? Now, I can do all that neat stuff by dragging a grid item unto a mx:Button, but with only one button. Maybe I could loop/repeater to make a vertical stack of buttons from an array? But then it gets unclear as to how each button is created with the necessary dragEnter and dragDrop event handlers. any help here? This wheel has been invented before. So how in Flex?

So I think what you really need to be doing is to have the list item
renderer accept the drop, rather than the list itself?
I'm sure I did this with the datagrid about a year and a half ago,
unfortunately I don't have that project to hand just now or I'd have a
look and see how I did it.
All I remember was it wasn't all that hard to do once I'd got that
concept.

Subject: [flexcoders] drag and drop ('into' the list items, while not adding
to the list itself; Ex: iTunes)
Hello All. I've run into a problem, need other perspective(s)/solutions:
Simply put: I want to implement drag and drop, like iTunes, in an AIR app.
Seems easy, but...this particular scenario is puzzling.
Right now, just like iTunes, I have two list-based controls (both are
populated from collections of data within SQLite), one is a DataGrid and one
is a List. Dragging and dropping from the Grid to the List is simple, yes,
but I would like to drop on the list item's label/text/name in the List and
perform another function (specifically an update to SQLite) and NOT simply
drop the item and append to the list. Follow?
As in iTunes, you can drag a song into a folder and it adds the song into
the folder. (I would make that reference in SQLite in this case). It
doesn't make a new folder by appending (wrongly) the dropped song to the
folder list. (Which is what I have now: If I drag a item from the grid and
drop it on the list, it's appended to the list, but I want it to become a
value within the list item (pseudo nested) not a value in the list itself.)
Is there a simple solution here I'm not seeing?
Now, I can do all that neat stuff by dragging a grid item unto a mx:Button,
but with only one button. Maybe I could loop/repeater to make a vertical
stack of buttons from an array? But then it gets unclear as to how each
button is created with the necessary dragEnter and dragDrop event handlers.
any help here?
This wheel has been invented before. So how in Flex?

RE: [flexcoders] drag and drop ('into' the list items, while not adding to the list itself; Ex: iTunes)
Yes! Last night around 2 AM I thought Oh, the item renderer should accept
it and then I went to sleep.
But I'm still puzzled as to how to fire the proper SQL statement for each
drop; essentially it's an INSERT [URL from drop] INTO table WHERE column =
[the drop acceptor's label string].
Example code rocks, of course, but small nudges will help me get through the
fog. Thanks to all who keep illuminating...

So I think what you really need to be doing is to have the list item
renderer accept the drop, rather than the list itself?
I'm sure I did this with the datagrid about a year and a half ago,
unfortunately I don't have that project to hand just now or I'd have a look
and see how I did it.
All I remember was it wasn't all that hard to do once I'd got that concept.
