I am looking for a way of getting the start of the week relative to today in Actionscript using (and currently stuck with) Flex 4.1. In Java I would do this using the Calendar class via:-
Calendar cal = Calendar.getInstance();
cal.setTime(new Date());
cal.set(Calendar.DAY_OF_WEEK,
1);
return cal.getTime();
I can't seem to find any solution that is anywhere as elegant - am I missing something?
There are two classes, of the same name, DateTimeFormatter. One is a pure Actionscript class, the other is a new class added to Flex 4.5 that wraps the Actionscript version. The Flex version does some of the heavy lifting for you.
There is a getFirstWeekday() method, it will be respective of the locale you specify.
[Edit]
I got carried away, didn't answer your question specifically. I'm not aware of anything more elegant than the DateTimeFormatter. But from there you can use a Date object to get the current time, and get what you're after.
There are a handful of date utilities, but I'm not aware of this particular solution. Are you looking for something like this:
var timeFormatter:DateTimeFormatter = new DateTimeFormatter(LocaleID.DEFAULT, DateTimeStyle.NONE, DateTimeStyle.SHORT);
var firstDay:int = timeFormatter.getFirstWeekday()
var now:Date = new Date();
var dayDelta:int = now.day - firstDay;
var firstDayInMillis:Number = now.time - (dayDelta * 86400 * 1000);
// you can construct a new Date from here: var first:Date = new Date(firstDayInMillis);

I'm trying to change the CreateDateTime for a node/document, but it doesn't appear to be having any effect. This is what I'm trying to far:
dynamic node = new DynamicNode(1065);
Document n = new Document(node.Id);
n.CreateDateTime = node.articlePublishedDate;
n.Save();
n.Publish(new umbraco.BusinessLogic.User(0));
umbraco.library.UpdateDocumentCache(n.Id);
Am I going about this in the right way? And also, am I correct in assuming that it can even be changed? The API seems to suggest the CreateDateTime has get/set, so it should work? Running the code through with breakpoints, it updates the CreateDateTime, but something with the save/publish seems to revert it back?
Your code is deprecated, so you need to use the "new" ContentService in umbraco:
https://our.umbraco.org/documentation/Reference/Management-v6/Services/ContentService
It should be something like this:
var cs = Services.ContentService;
var node = cs.GetById(1065);
node.CreateDate = DateTime.Now;
cs.SaveAndPublish(node);
The question was here for a long time with bounty and no satisfying solution for me. I erased the first post and am posting instead a question that can be answered quickly with a yes or no so I can proceed with my doings.
If you could answer it really fast before it's deleted by "not a good question". Is using a custom shape from PhysicsEditor to Nape the same as doing it with Box2D? (ofc changing syntax)
If you could then give a look in that link then say it's the same process in Nape that'll be enought thanks.
I ask this because I found the Box2D tutorial easier to follow so far.
public var floor:Body;
floor = new Body(BodyType.STATIC);
var floorShape:PhysicsData = new PhysicsData();
floor.shapes.add(floorShape); // Error: Implicit coercion of a value of type PhysicsData to an unrelated type nape.shape:Shape.
floor.space = space;
Update:
According to a comment on this blog post, it sounds like recent versions of Nape have broken compatibility with the physics editor. Specifically, the graphic and graphicUpdate properties no longer exist on body objects. The solution suggested is to remove references to those properties.
I'm not in a position to be able to test this, but you could try updating the createBody method of your floor class as follows:
public static function createBody(name:String /*,graphic:DisplayObject=null*/):Body {
var xret:BodyPair = lookup(name);
//if(graphic==null) return xret.body.copy();
var ret:Body = xret.body.copy();
//graphic.x = graphic.y = 0;
//graphic.rotation = 0;
//var bounds:Rectangle = graphic.getBounds(graphic);
//var offset:Vec2 = Vec2.get(bounds.x-xret.anchor.x, bounds.y-xret.anchor.y);
//ret.graphic = graphic;
/*
ret.graphicUpdate = function(b:Body):void {
var gp:Vec2 = b.localToWorld(offset);
graphic.x = gp.x;
graphic.y = gp.y;
graphic.rotation = (b.rotation*180/Math.PI)%360;
}
*/
return ret;
}
This code is not java code, and I'm not getting any answer from ActionScript developers. So I tagged it with java, but Action Script is similar to java and this an OOP question.
I'm using Grid Data and I want to accomplish this following task:
Method 1: I want to multiply each row Row1num1 * Row1num2 and so on,
var Row1num1:String;
var Row2num2:String;
var Row2num1:String;
var Row2num2:String;
var Row3num1:String;
var Row3num2:String;
var event1:Object={num1:Row1num1,num2:Row1num2};
var event2:Object={num1:Row2num1,num2:Row2num2};
var event3:Object={num1:Row3num1,num2:Row3num2};
then add them to a dataGrid
dataGrid.columns =["num1","num2"];
dataGrid.addItem(event1);
dataGrid.addItem(event2);
dataGrid.addItem(event3);
but by using this method, if I have 20 rows, I will have a lot of variables, obviously it's bad.
method 2: In this method creating Grid Data rows at runtime and multiply them.
//button to add rowGrid
dd.addEventListener(MouseEvent.CLICK,ddd);
var numm:String="34";
function ddd(evt:MouseEvent):void
{
var event4:Object={num1:Rownum1,num2:Rownum2};
dataGrid.addItem(event4);
}
but when I use this method, I have a hard time accessing each row data and multiply them.
This example because I'm creating GPA calculator and I want to take each row credit Hours and multiply them with the scale value at the same row, first method is bad because there's not abstraction .
The second method what I'm hoping to work ,because I want user to add row depend on their number of courses.
I hope my English is not bad.
I hope my question don't get vote down, and by reading this question can you determine what I'm missing so I can learn it .
And is there any tutorial I can use to solve my problem?
I'm just addressing your first method for now, but it almost seems at though you want an array of some sort.
Here's a link on how to use Actionscript arrays.
If you need more dimensions, you can make an array of arrays. This will help you cut down on the number of variables.
I hope I correctly understood your question. I'll give it a go either way...
So, one of the best things about actionscript in comparison to most other strongly-typed Object-Oriented languages is how easy reflection is (probably thanks to its javascript origins).
That being said, what you can do is simply create an array using a "for" loop. What I am assuming is that the variables row1Num1 row2Num2 and so on already exist in your class. Otherwise, obviously it would be much more efficient to store them in an array and simply read from it into a new array. Anyhow, the code should look something like this:
method 1:
var eventsArr:Array = [];
for(var i:int = 1; this["row" + i + "Num1"] != undefined /*or i<=length*/; i++){
eventsArr.push({num1:this["row" + i + "Num1"], num2:this["row" + i + "Num2"]});
}
for(var j:int = 0; j < eventsArr.length; j++){
dataGrid.addItem(eventsArr[j]);
}
method 2:
dd.addEventListener(MouseEvent.CLICK,ddd);
var numm:String="34"; //I am assuming this refers to the row number you wanted to add.
function ddd(evt:MouseEvent):void
{
var event4:Object={num1:this["row" + numm + "Num1"],num2:this["row" + numm + "Num2"]};
eventsArr.push(event4);
dataGrid.addItem(event4);
}
Hope that helps.
Introduction:
I have an AdvancedDataGrid displaying hierarchical data illustrated by the image below:
The branch nodes "Prosjekt" and "Tiltak" display the sum of the leaf nodes below.
Problem: I want the root node "Tavle" to display the total sum of the branch nodes below. When i attempted to do this by adding the same SummaryRow the sum of the root node was not calculcated correctly(Every node's sum was calculated twice).
dg_Teknikktavles = new AutoSizingAdvancedDataGrid();
dg_Teknikktavles.sortExpertMode="true";
dg_Teknikktavles.headerHeight = 50;
dg_Teknikktavles.variableRowHeight = true;
dg_Teknikktavles.addEventListener(ListEvent.ITEM_CLICK,dg_TeknikktavlesItemClicked);
dg_Teknikktavles.editable="false";
dg_Teknikktavles.percentWidth=100;
dg_Teknikktavles.minColumnWidth =0.8;
dg_Teknikktavles.height = 1000;
var sumFieldArray:Array = new Array(context.brukerList.length);
for(var i:int = 0; i < context.brukerList.length; i++)
{
var sumField:SummaryField2 = new SummaryField2();
sumField.dataField = Ressurstavle.ressursKey + i;
sumField.summaryOperation = "SUM";
sumFieldArray[i] = sumField;
}
var summaryRow:SummaryRow = new SummaryRow();
summaryRow.summaryPlacement = "group";
summaryRow.fields = sumFieldArray;
var summaryRow2:SummaryRow = new SummaryRow();
summaryRow2.summaryPlacement = "group";
summaryRow2.fields = sumFieldArray;
var groupField1:GroupingField = new GroupingField();
groupField1.name = "tavle";
//groupField1.summaries = [summaryRow2];
var groupField2:GroupingField = new GroupingField();
groupField2.name = "kategori";
groupField2.summaries = [summaryRow];
var group:Grouping = new Grouping();
group.fields = [groupField1, groupField2];
var groupCol:GroupingCollection2 = new GroupingCollection2();
groupCol.source = ressursTavle;
groupCol.grouping = group;
groupCol.refresh();
Main Question: How do i get my AdvancedDataGrid's (dg_Teknikktavles) root node "Tavle" to correctly display the sum of the two branch nodes below?
Side Question: How do i add a red color to the numbers of the root node's summary row that exceed 5? E.g the column displaying 8 will exceed 5 in the root node's summary row, and should therefore be marked red
Thanks in advance!
This is a general answer, without code examples, but I had to do the same just couple of days ago, so my memory is still fresh :) Here's what I did:
Created a class A to represent an item renderer data, extended it from Proxy (I had field names defined at run time), and let it contain a collection of values as it's data member. Once accessed through flash_proxy::getPropery(fieldName) it would find a corresponding value in the data member containing the values and return it. Special note: implement IUID, just do it, it'll save you couple of days of frustration.
Extended A in B, added a children property containing ArrayCollection of A (don't try to experiment with other collection types, unless you want to find yourself examining tons of framework code, trust me, it's ugly and is impossible to identify as interesting). Let B override flash_proxy::getPropery - depending of your compiler this may, or may not be possible, if not possible - call some function from A.flash_proxy::getPropery() that you can override in B. Let this function query every instance of A, which is a child of B, asking the same thing, as DataGrid itself would, when building item renderers - this way you would get the total.
When creating a data provider. Create an ArrayCollection of B (again, don't try to experiment with other collections--unless you are ready for lots of frustration). Create Hierarchical data that uses this array collection as a source.
Colors - that's what you use item renderers for, just look up any tutorial on using item renderers, that must be pretty basic.
In case someone else has the same problem:
The initial problem that everything was summed twice, was the result of using the same Array of SummaryField2 (sumFieldArray in the code) for both grouping fields(GropingField2 tavle and kategori)
The Solution to the main question: was to create a new array of summaryfields for the root node(in my intial for loop):
//Summary fields for root node
var sumFieldRoot:SummaryField2 = new SummaryField2();
sumFieldRoot.dataField = Ressurstavle.ressursKey + i;
sumFieldRoot.summaryOperation = "SUM";
sumFieldArrayRoot[i] = sumFieldRoot;
Answer to the side question:
This was pretty much as easy as pointed out by wvxyw. Code for this solution below:
private function summary_styleFunction(data:Object, col:AdvancedDataGridColumn):Object
{
var output:Object;
var field:String = col.dataField;
if ( data.children != null )
{
if(data[field] >5){
output = {color:0xFF0000, fontWeight:"bold"}
}
else {
output = {color:0x006633, fontWeight:"bold"}
}
//output = {color:0x081EA6, fontWeight:"bold", fontSize:14}
}
return output;
}
Is there any ActionScript class which represents "durations of time", similar to the TimeDelta class in Python?
Edit: Thanks for the responses. I should clarify a bit, though: I want be able to ask questions like "how many weeks are between date0 and date1" or "let x represent "one day". What is date2 + x?"
I know I can do all this by representing dates as timestamps... But I'm hoping to find something nicer.
I posted a full AS3 port of the .NET TimeSpan class on this question, which sounds exactly like what you need.
// 5 days from new
var ts : TimeSpan = TimeSpan.fromDays(5);
var now : Date = new Date();
var fiveDaysTime : Date = ts.add(now);
// Diff between dates
var d1 : Date = new Date(2009, 1, 1);
var d2 : Date = new Date(2009, 1, 6);
var ts : TimeSpan = TimeSpan.fromDates(d1, d2);
You can use time() in the Date class to get unix era milliseconds and use that for time delta.
If you subtract two dates:
var dateDiff = date1 - date2;
dateDiff will hold the number of milliseconds between the two dates. You can then convert from milliseconds to whatever useful number you like.
I don't think there is a class which measures change in time in Actionscript 3. According to this blog post on Adventures in Actionscript, timing is very inaccurate in the Flash player on the web. That post is pretty informative and has a class called SuperTimer that might help you. You might want to keep this inaccuracy in mind if using solutions posed by Justin Niessner and toastie.
