Flex :: Using 9-Slice Scaling With Images Loaded At Runtime?

Nov 8, 2010

Is there a way to use 9-slice scaling with images loaded at runtime? To clarify, let's say that I build an application that lets a user skin a button with whatever image they want. This would be an image that's not embedded with the swf. Is there a way to set that runtime image as a background and use 9-scaling?

Flex :: Change The Color Of An Mx:PieSeriesItem Slice Dynamically?

Feb 15, 2011

I am creating a program where a change in a value causes the color of a pie slice in an mx:PieChart to change dynamically.the code that is supposed to change the color is similar to this:(pieChart.pieChartSeries.items[i] as PieSeriesItem).fill = new mx.graphics.SolidColor(0,0.2); // black, almost opaquetracing out the results of this appears to apply the color to the particular PieSeriesItem, but the color does not change visually. I checked the AS reference and the fill property is of type iFill and should accept a solidColor instance. (note: I have also tried 0x000000 as a valid color, the first argument of SolidColor takes an uint)edit] Since I posted the question originally, I've added a few changes to clarify the question. am actually using an MXML component that extends < mx:PieChart > . Originally I was trying to set the color as listed above within an event handler in the main application. What I have done since then was invoke a method in my extended PieChart component, like so:

(in main applicaion)
private function someEventHandler(evt:someEvent):void{
pieChart.setPieSliceColor((pieChart.pieChartSeries.items[i] as PieSeriesItem));

Flex :: Calculate The Sum Of A Datagrid's Rows?

Jun 6, 2010

I have this datagrid which has columns with a NumericStepper as an itemEditor where the user can change the number of items he wants to buy. How can I calculate the sum of all cells when the user updates datagrid's values?

EDIT 1

My datagrid is about colors and sizes of a product. The columns are generated dynamically from this function

private function getColumn(dataField:String, headerText:String,editable:Boolean) : DataGridColumn
{
var column:DataGridColumn = new DataGridColumn(dataField);

[Code]....

the row.size28 is generated dynamically. So it could be row.size29,row.size30 etc.

How can I loop through all my cells without knowing their data.property?

Like Height/per row height.As I known, the dropdown.y is the relative y coordinate of itself. But my dropdown has many parent UI layout component, and also I have many dropdowns, it is hard to calculate one by one.

Actionscript 3 :: Flex - Calculate Hours Between 2 Times?

Oct 23, 2009

I am building a scheduling system. The current system is just using excel, and they type in times like 9:3-5 (meaning 9:30am-5pm). I haven't set up the format for how these times are going to be stored yet, I think I may have to use military time in order to be able to calculate the hours, but I would like to avoid that if possible. But basically I need to be able to figure out how to calculate the hours. for example 9:3-5 would be (7.5 hours). I am open to different ways of storing the times as well. I just need to be able to display it in an easy way for the user to understand and be able to calculate how many hours it is.

.slice() To Copy An Array?

May 25, 2009

I am trying to use .slice() to copy an Array of Loaders (each with a jpg loaded in it), as follows:
 
newArray = oldArray.slice();
 
and it works, but the problem is, any changes I apply to one Array applies to both, as though .slice() had just copied a pointer to the same Array, but I was specifically told that .slice() would not exhibit that pblm. Before I just go back to loading the same images twice, is there something special about Arrays of Loaders or something else I might be missing?
