[flexcoders] selecting a cell in an advanced data grid
Hi, I have an advanced data grid with hierarchical data, displayed in
tree view.
Selecting a cell updates a pie chart to show the breakdown for the
node, by passing to a modelLocator value:
model.expenditure.selectedItem = e.itemRenderer.data as CategoryObject;
which the pie is bound to.
This is straightforward enough, but I also need it to work in the
other direction, so that if the pie segment is drilled-down into, the
selected cell in the ADG is changed. (The pie click updates the
model.expenditure.selectedItem). However, I don't know how to go about
finding this cell!
How can I loop through the ADG's elements to find the co-ordinates for
the cell to select??
I really hope you can help, this is driving me crazy!

HierarchicalData(rptAccordions.currentItem.children)}

[flexcoders] Dissolving between two charts
Hi,
I have a line chart and a stacked column chart laid one over the other
in a canvas. I would like, when a button is pressed, to dissolve from
on to the other.
I figured setting the alpha of one chart to 0 and then doing a state
transition with an mx:Dissolve ../ would do the trick, and it works
to a large extent, but I have a real problem with the axes.
Setting the alpha property of the chart hides *only* the line or bars,
not the axes. Exactly the same setting the alpha of the chart's
container; only the coloured section of the chart is hidden. I set the
alpha on the AxisRenderers to 0, too, but this seemed to do nothing!
So the code below still shows the axes, which means that both chart
axes are visible in every state.
mx:Canvas width=70% height=100% id=cvsColumnChart alpha=0.0
mx:ColumnChart alpha=0.0
id=columnChart
dataProvider={dpStackedLineChart}
creationComplete=changeSeries()
width=100% height=100%
showDataTips=true
dataTipFunction=renderColumnTips
type=stacked
mx:verticalAxisRenderers
mx:AxisRenderer id=colChartVerticalAxis canDropLabels=true
axis={va1} alpha=0.0/
/mx:verticalAxisRenderers
mx:horizontalAxisRenderers
mx:AxisRenderer id=colChartHorizontalAxis
canDropLabels=true
axis={catAxis1} alpha=0.0/
/mx:horizontalAxisRenderers
mx:verticalAxis
mx:LinearAxis id=va1/
/mx:verticalAxis
mx:horizontalAxis
mx:CategoryAxis labelFunction=renderDate id=catAxis1/
/mx:horizontalAxis
/mx:ColumnChart
/mx:Canvas
Any ideas how I can achieve a nice dissolve from one chart to another,
including the axes?
Thanks!
[flexcoders] selecting a pre-determined row in a datagrid
Hi. I have a datagrid component which has a dataProvider of an arraycollection of objects. I also have a variable selectedItem, which holds an object that has been selected elsewhere in the application. What I need is, when I create my datagrid, to set the background colour of the row corresponding to this selectedItem object. So I guess I need to loop through the dg's rows, comparing the dataItem of the row to selectedItem. However, I don't know how to loop the rows in a DataGrid?? It's so easy in C#.NET, and not here, so I think I may be approaching this from the wrong angle. Any ideas? Thanks!
[flexcoders] Re: 'Pointer' in actionscript?
Thanks, I figured it out that when using simple object types, things
seem to be passed by value, whereas with complex data types, they are
passed by reference.
So your suggestion of simply changing itemLocation to an
ArrayCollection sorted it out.
Cheers!

You may want to try some combination of the following:
1) Do the setting in the setter tather than the getter
2) Type itemLocation as ArrayCollection rather than Object
3) Use BindingUtils to set up a binding as shown in this example

[flexcoders] binding mx:tree to custom class
Hi,
I have a data structure which looks a little like this:
items:ArrayCollection is an array of objects with class Item:
Item:
name:String
category:String
data:ArrayCollection is an array of objects with class Detail:
Detail:
name:String
type:String //either income or detail
val:Object
So, I would like to create a tree with dataProvider={items} that
looks like:
-Item[name]
Detail[name]
Detail[name]
Detail[name]
-Item[name]
Detail[name]
Detail[name]
Now, if the data was in XML or just a basic ArrayCollection, this
would be straightforward, but not sure how to accomplish it with my
custom classes?
Sorry about the simple question, quite new to Flex!
Thanks for your help,
F
[flexcoders] 'Pointer' in actionscript?
Hi.
I have a custom component which uses data from my modellocator.
Depending on the way this component is called depends where abouts
this data comes from,
ie:
private var _itemLocation:Object;
[Bindable]
protected function get itemLocation():Object
{
if(isAssets)
_itemLocation = model.factfind.assets;
else
_itemLocation = model.factfind.liabilities;
return _itemLocation;
}
protected function set itemLocation(value:Object):void
{
_itemLocation = value;
}
model.factfind.assets and model.factfind.liabilities are both
ArrayCollections.
then, later on, I have
mx:Label text={itemLocation.selectedAssets.getItemAt(0).name}/
Now, this doesn't update as I'd expect when the first item in
itemLocation.selectedAssets changes (whatever itemLocation refers to)
If I change it to
mx:Label
text={model.factfind.assets.selectedAssets.getItemAt(0).name}/
it works perfectly.
So it seems that when I do the set/get on itemLocation, it copies the
value of model.factfind.assets/liabilities rather than acting as a
pointer to that.
How do I get it to work like a pointer so when model.factfind.assets
changes, so does itemLocation, in order that I can use the same
component for both assets and liabilities?
Thanks
[flexcoders] Re: Thinking about going to the dark side....Apple Mac Book
I use a little ole' MacBook for most of my development. All my .NET stuff runs on my Windows partition using Parallels and Virtue Desktops, faster than my fully-fledged PC lappy, and then enerything else is done on OSX. I was a little dubious at first when this configuration was advised to me, but it works fantastically. Devving, testing and debugging in the two environments within one little (beautifully crafted and developed) box. Awesome. If you are looking to get one, the new MacBook Pro is rumoured to be announced on 9th June, so wait for that, and whatver you do, buy the minimum RAM from Apple and upgrade it yourself, cuz theirs is a rip-off!

[flexcoders] choosing line series
I have a question about adding series to a LineChart.
My data looks like this (simplified pseudo-code):
selectedItems:ArrayCollection
{
Item:myClass
{
id:int
history:ArrayCollection
{
date:Date
val:Number
}
}
}
so, a user adds objects of myClass to the selectedItem
ArrayCollection. There may be any number of these.
Now, I currently have a linechart which displays the history data for
any one myClass object:
mx:LineChart
id=lineChart
dataProvider={dp}
mx:horizontalAxis
mx:CategoryAxis categoryField=date /
/mx:horizontalAxis
mx:series
mx:LineSeries yField=val /
/mx:series
/mx:LineChart
So this plots val by date.
What I would like to do is amend this so that, rather than passing an
individual myClass object to the linechart, I pass an ArrayCollection
containing several, and then plot the val for *each* object's history
on a separate line.
The only examples of multiple series I have seen expects each object
to have a property relating to each series:
new ArrayCollection( [
{ Month: Jan, Profit: 2000, Expenses: 1500, Amount: 450 },
{ Month: Feb, Profit: 1000, Expenses: 200, Amount: 600 },
{ Month: Mar, Profit: 1500, Expenses: 500, Amount: 300 } ])
and then plotting Profit, Expenses and Amount as the three series
against Month.
Mine's subtley different... any ideas?
Thanks!
[flexcoders] confusion with events
I have a question about how events are used. I have a component which has the following sub-components: mx:HBox width=100% id=assetBox view:AssetGraphPanel height=100%/ view:AssetAccordion id=accordion / /mx:HBox The AssetGraphPanel itself contains components: mx:PieChart id=topPie ... /mx:PieChart assets:SmallGraph person=Joint/ assets:SmallGraph person=Client/ assets:SmallGraph person=Partner/ These graphs need to change when a button inside the AssetAccordion is clicked, by calling a function in SmallGraph called 'updateChart()'. There will be other things that should also trigger this function to be called, from other components. So, how do I add an event listener/dispatcher so that the SmallGraph can hear it whereever in the application it was fired from? Seems to me I want the opposite of bubbling? Thanks for your patience.
