[flexcoders] How to force construction when creationPolicy=all' does not work?
ViewStack.vsMainDash VBox.vbDrctrDash VBox.vbParmsAndDrills ViewStack.vsDashDrills VBox.CustLevel VBox.UDAC is the hierarchy.

[flexcoders] communicating between SharePoint and Flex?
Specifically I need to take the logged in user info from the UserControl web part and get it into the Flex app which is sitting in a PageViewer webpart. Generally I want to learn as much as I can about SP to Flex communication because I think there is a tremendous opportunity for Flex developers to embed Flex apps into SharePoint pages ... Flex works :-). Any pointers towards how to communicate between SP and Flex would be much appreciated. Google has not come up with any real examples yet. TIA, Regards, Mic.

[flexcoders] Re: item renderer in ComboBox not consistent
Thanks valdhor - great solution! I had got this far but was using a textInput
and its background color, and even though I had
editable=false;
enabled=false;
the cursor would go into the row. Not good. Question: I had to modify to
g.beginFill(0xE8E8E3, 0.5);
otherwise the line highlight would not show through and could not tell what
line was highlighted. It surprised me that a renderer was capable of doing this.
Thanks again,
Mic.

[flexcoders] Re: item renderer in ComboBox not consistent
Hi Jeff, what this does is set the background color of the renderer's VBox and
therefore the line shading to gray if the label text begins with an asterisk
we want to highlight these paricular rows in the list. I know what you are
saying about creationComplete() only running once, but I was thinking the
renderer would have to redo itself on a scroll because the viewable area had
changed.
--- In flexcoders@yahoogroups.com, Jeffry Houser j...@... wrote:
It looks like you are trying to change the background color of the
label so that you have alternating colors, is that correct?
This won't work due to render recycling. Renderers are re-used. There
is not a single renderer for every item in your dataProvider.
CreationComplete complete only runs once.
You might try code like this on the dataChange event. Or using
updateComplete.
Or google it and discover the alternatingItemColors style:

[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:CheckBox
selected={data.rmvDir == 'true'} paddingLeft=10
labelPlacement=right

With everything turned off on the grid, the cb can be checked and the
handler runs. Appreciate a solution to this. TIA,

[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] Re: How to put a well-formatted SQL statement in a string?
Hi Tracy,
I bought the $19 FlexCubed FlexSQL, which uses a SWC and a server-side asp
which I place in wwwroot/website. Talked to them and they do not support procs
deadline means having to embed while look for proc solution. They pass the
e.g. select statement to their SWC as a string, and my select statements are
basically the proc contents so pretty long - nightmare without the indents and
lines normally associated with sql formatting :-)
I grabbed the FlexSQLAdmin google code open source - I cannot get it passed the
SharePoint security - been talking to him but he is not Sharepoint aware.
The more I look at SharePoint and asp.net etc the more I appreciate my attempt
to write this app in Flex and embed into SharePoint page :-) I think probably
MS is positioning Silverlight to code RIAs inside SharePoint?

How are you communicating with SQLServer? You should be aware that using
native http has security consequences. So does allowing dynamic sql. You
would do better to use a server side process to integrate with the database.

[flexcoders] Flex, SharePoint and SQLServer
Just got introduced to the wonderful world of SharePoint recently, and am contemplating coding the client's BI application in Flex and then embedding into SharePoint. Are people doing this? All the data must come from SQLServer2005. Done some googling and understand that I could 1. Load data into SharePoint lists and then send to Flex 2. Talk to 2005 directly from Flex. Is this correct and which is the better approach? Are there any examples of this kind of architecture? I did not really find much after a couple of hours of googling. I have looked at ASP.NET and VisualStudio etc and just feel I could do a better job with Flex. Don't want to infer Flex is superior, but I do know that I can write the app they need in Flex. Is this a sensible approach? Thanks in advance for any pointers, Mic.

[flexcoders] Re: event passing when source/destination are on different parent bubbling chains?
Very interesting! At the moment I have bound that modelLocator var to State changes within the components, but am finding that this only goes so deep as the children below a certain depth do not exist when their parent does a State setProperty on them. Gonna try the set method now ... thanks very much, Mic. --- In flexcoders@yahoogroups.com, jer_ela g...@... wrote: You need a loggedIn property somewhere in your model.

[flexcoders] What is equivalent of Cairngorm Command Sequence in Cairngorm UM?
Login button dispatchs login event, Command - Delegate - Server - Command result has user_id - null user_id = callback to view, non-null user_id loads more data. In this standard Cairngorm app I am using Command extends SequenceCommand to executeNextCommand(); and dispatch loadDataEvent. Because we need view callback I am updating to UM. In reading the UM stuff it looks like a) Delegate can intercept the response that would normally go the Command b) Presumably Command result can create the loadDataEvent (UM event) and dispatch it. I don't think I want the Delegate to intercept because the returned user_id must be written to a VO in the ModelLocator also, and I am presuming that this is always a job for Command (?). So do I just replace Command result executeNextCommand(); with create and dispatch next event? I am wondering if there is more to this, because the consensus appears to be that standard Cairngorm Command Sequence is ugly and UM is more elegant. TIA, Mic.

[flexcoders] sprite.startDrag() - Only one sprite is draggable at a time :-(
Requirements are for a draggable calculator pop-up that looks like a calculator i.e. the calculator image is the frame/border - irregular shape - no rectangularPanel/TitleWindow. I created 2 components, the calculator Image and an inner Panel component with calculator functionality, titleBar drag and resizing. The size of the outer calculator Image is bound to the resize of the inner Panel e.g. var watcherSetter:ChangeWatcher = BindingUtils.bindSetter(calculatorImageWidth,sPanel,width); and this works perfectly. So I coded the synchronized drag of the 2 components with a titleBarMoveHandler() on the alpha=0 TitleBar of the inner Panel: this.startDrag(); calculatorImage.startDrag(); and then found the fine print - sprite.startDrag() - Only one sprite is draggable at a time. So somebody gets left behind :-) Can google no examples of this kind of thing, so any pointers appreciated. TIA, Mic.

[flexcoders] simple(?) Flex change color question
This one is making my head hurt ... will there be any perceivable difference in a) slowly changing an object's color from it's current color e.g. 0xFF to 0xFF and b) slowly changing the object's color by morphing the correct individual r, g and b from 0xFF to 0XFF? Will it pass through the same shades on the way from current to new? Reason I wonder is that I am looking at some PixelBlender filters that change the tint of objects by manipulating the r,g,b components is this different to just changing the color attribute?

[flexcoders] Fireworks .fxg to Gumbo - all Group ids=undefined problem
Exporting Fireworks .fxg creates every Group with an id = undefined. This will not load into Gumbo because obviously the ids must be unique. Is this something that Fireworks can automatically fix, or do I need to write a text parser in Flex that can go out and write unique ids to all the groups in the .fxg file before it can be used in FxApplication? As always TIA, Mic.
[flexcoders] getting refs to items in Group.mxmlContent?
(OK to ask Gumbo questions?)When an .fxg file is loaded into FxApplication and added to a Group, and that Group is then added to FxApplication, array mxmlContent[0] contains the .fxg Graphic object, whose child Groups can be accessed directly by name: displayGroup.mxmlContent[0].myGroup1 However I cannot access mxmlContent[0] with getChildAt() etc, nor can I work out how to extract out references to mxmlContent[0] into another array etc so a list can be displayed where a Group object might be selected. Can find no info on mxmlContent :-( code: testFXG.fxg contains group id=myGroup1, group id=myGroup2 etc private var displayGroup:Group; displayGroup = new Group(); var source: testFXG= new testFXG(); displayGroup.addItem(source); addItem(displayGroup); breakpoint shows: displayGroup [inherited] mxmlContent [0] myGroup1 myGroup2 etc code: private var testGroup:Group; testGroup = displayGroup.mxmlContent[0].myGroup1; - this is a good reference and can be used to change myGroup1.x, myGroup1.y etc. However as stated above I cannot get a reference to e.g. the 3rd child etc. As always, TIA, Mic.

An id on an mxml tag works as a reference because the compiler creates
an instance variable with the name specified in the id property, and
assigns a reference to the component instance to it.
If you manually addChild(), you need to do the same.

[flexcoders] basic carousel - force redraw after setChildIndex?
needing a basic rotation of 5 figures, I place the 5 images on the
canvas and then start calculating the x,y, scaleX etc. Then I run
through the array referencing the images and reset the childIndex:
private function moveThem():void
{
calculateAngles(); // calculate x,y, scaleX
assistantsArray.sortOn(scaleX); // ascending
for(var i:uint = 0; i assistantsArray.length; i++)
{
canvas1.setChildIndex(assistantsArray[i], i);
}
}
Running moveThem() from a button click, does rotate the figures . But
when I put a loop inside moveThem to run the code e.g. 100 times , I
still get 1 redraw with the resulting positions being equal to 100
moves. So does Flex execute one redraw per code stack? And do I need to
invalidate the DisplayList or something within the moveThem loop? TIA,

[flexcoders] Re: change selected tab using variable containing tab label string?
Thanks all - since the whole app is pretty much built at runtime from an
xml template, and each gui component knows its identity from its
encapsulated xml node, I wanted to pick up some efficiency by not having
to parse the data providers continually ... but you made me think :-)
and I am going to save the tab bar and viewstack indexes within the xml
nodes, so e.g. drilling on a chart axis can change a tab by index rather
than by trying to translate the tab label from the xml node.

[flexcoders] passing data with custom event up displaylist chain?
is it true to say that a custom event can communicate nothing except
an event has been sent, and that in order to send data, an event
subclass with public properties has to be coded? I have a tileList
deep within containers that must communicate its selectedItem to a
higher-level Canvas. I thought I might be able to somehow get the info
into the custom event before it is sent:
mx:Metadata
// [Event(updateStuff, type=flash.events.Event))]
[Event(updateStuff, type=flash.events.MouseEvent)]
/mx:Metadata
mx:TileList id=myTileList click = updateStuff(event)
private function updateStuff(e:Event):void{
var eventStuff:Event = new Event(updateStuff,true);
// put e data into eventStuff; - cannot do this :-)
this.dispatchEvent(eventStuff);

I am presuming that it does not make sense to bubble the tileList
MouseClick up the chain and then have the higher-level Canvas listener
trap every mouse click and look for a currentTarget of myTileList.

[flexcoders] x,y position of inner container relative to app?
I need to constrain a popup to a container embedded deep within canvases and modules. A popup belongs to SystemManager and its parent is the main app, so 0,0 sends it to the top left of the browser. Can a deeply embedded container get its position relative to the app? I can hard-code popup restraining values of course, but these would not work if the user resizes the browser. TIA, Mic.
[flexcoders] path for loading module swf from server - help please ...
I have got modules loading fine when my project is on a local drive. But I am having trouble with the correct module path for a project that is set up on a ColdFusion server. I have located the module swf in the TestProject-debug folder, and thought that the following would work: mx:ModuleLoader url=http://server1:8500/TestProj-debug/com/modules.TestMod.swf; ready=applyModuleSettings(event) error=errorHandler(event)/ Error = URL Not Found. Is my syntax off or is this the wrong place to look for the module? As always, TIA, Mic.

Subject: [flexcoders] FlexLivedocs Module chart example has scroll
bars
http://livedocs.adobe.com/flex/3/html/help.html?content=modular_5.html
Can anyone show me how to fix this simple example so the chart shrinks
to fit its container like it normally does? TIA,
Mic.
[flexcoders] Now have them contained but with scrollbars ....
and all the Google examples of Module and ModuleLoader I have found
show scrollbars and not shrink to fit. The chart is in a VBox:
mx:VBox width=100% height=100%
mx:LineChart id=chart
dataProvider={salesArizona}
height=100% width=100%
and without the Module wrapper shrinks to fit its VBox. What is it
about Module that inhibits this default behaviour, and how does one
get the chart to shrink to the VBox - scrollbars look bad :-(
TIA,
Mic.

[flexcoders] Adding text to lineSegmentRenderer?
Thanks for everybody's help. I will pursue the possibility that there
is _accessible_ info in the chart object that the line series can use
to learn about the column series. In the meantime client says just
draw a line segment with the percentage value displayed, so I say no
problem thinking that I can just place a displayed label on each line
series segment except that there are no labels for a line series
... surprised the heck out of me ... so how do I insert text into a
graphical environment?
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
{
g.drawRect(item.x, item.y,(50,5);
Do I add some kind of child text object here? TIA,
Mic ( I need a drink)
