View 1 RepliesI have a entire XML and I've already loaded it. How do I get a specific node? For example:
<images>
<image url="" label="" etc=""/>
<image url=""/>
<image url=""/>
</image>
I need to pass the entire node through params
Like this:
var node:XML = xml.images[0];
trace(node); // <image url="" label="" etc=""/>
Is that possible?
I was wondering about MC and hey can help to lag a game out. I set up an advanced class system so i don't have to use MC to simulate walls, all i use isthe x,y,width and height. Well anyway since i don't need MC anymore I was wondering if there is a way to attach Graphics instead of MC cause a Graphics file size is relatively small than that of a graphic, I think. If anyone could tell me thats true and show me a way to attach graphics that would be nice. I haven't tried it yet but maybe if I exported the graphic from the library imihgt be able to call its name, but it doesn't have an instance name so im stuck.

View 2 RepliesI know flex is a client side technology, but our customers are asking us to e-mail them reports (i.e. graphic images) that look just like the flex graphics we show them on the desktop on a nightly basis.
View 3 RepliesI know that there is no such function as getElementByName in Flex but I also now that you can do this["object_id"] to get the element of the application u're in.What about getting an element inside another element?I've tried making element["id"] ? But in my try-catch it always runs the "catch" part..how do I get an element inside another element just having it's id in dynamically created string form?
View 2 RepliesI have flash where there is a link for song download. And, at the bottom of the flash I've a count, loaded thorugh flash vars which should increment everytime donload button is hit. Please let me know what approach should i take to do that. can i call a Java method on donload button which will insert a row in the table and and then get the count and render it to the count variable in my flash?
May be this extremely confusing. Here is a very similar example on how it is done. This is actually very similar to what i want to do. [URL] on this link there is count below which increments you hit the download button.

View 1 RepliesI'm using flex and drawing a circle using the Spark Ellipse primitive. I am setting the x,y coordinates of the circle myself. I am drawing them within a TitleWindow component. Is it possible to force the circle to not be allowed if I specify a coordinate that is outside the TitleWindow? Or do I have to check the coordinates manually myself?
View 1 RepliesIs there anyway I can effectively call the equiv. of setText on a Flex Graphics object ?Specifically I'm using a custom cell renderer to display data in a datagrid. The renderer uses the Graphics object to set the background colour of only a portion of the cell (say the left half) based upon the underlying data. I would like to be able to have text over only that portion of the cell which has the background colour (eg centred within the left half). I know all the widths (of both the cell itself and the graphics object) but I don't know how I can set text (centred) over the graphics object.

I need to create flash content dynamically- towards that need to build images. I need help on two points
a) are vector graphics always better than raster graphics on size/ do vector graphics take longer to render
b) do we have open-source tools to create fxg files to import into flex builder
I have created a few flex primitives on screen via action script. Now based on business logic, I need to make changes to some of these primitives such as: changing thickness, direction of arrowhead etcOne thought was to assign id's to these primitives as they are built- how do I do that?e.g. I get a line built as below
var myShape:Shape=new Shape();
myShape.graphics.lineStyle(thickness,color);
myShape.graphics.moveTo(XFrom,YFrom);

I am building a flex project involving drag+drop of fxg graphics. My graphic is instantiated as below:
<graphics:arrow2 id="object" mouseMove="mouseMoveHandler(event);" />
I get an error: "Call to a possibly undefined method Graphic."
This works if I change my drag-object to Image and replace the 'Graphic' below with 'Image'. What should I use to be able to reference the fxg graphic in the drag-drop? My drag drop functionality is as follows
private function mouseMoveHandler(event:MouseEvent):void {
var dragInitiator:Graphic = Graphic(event.currentTarget);
var ds:DragSource = new DragSource();
ds.addData(dragInitiator,"gph");
DragManager.doDrag(dragInitiator, ds, event);

I'm drawing a line using this code:
this.graphics.moveTo(posx, posy);
this.graphics.lineTo(2*posx,2*posy);
But now I want to remove it, but I can't clear the whole this.graphics object because it contains more information that is useful for me. How can I remove this line without clearing this.graphics object? Is there any method to draw a similar line over it to hide or replace the line?
I've built a rather robust tooltip class recently that attaches and draws a single tooltip sprite to the root, then uses MOUSE_OVER to detect when it is over a tooltippable object, and shows the appropriate tooltip text. At the moment, I'm ensuring that any elements in my application which wants to take advantage of showing tooltips implement the ITooltippable interface, and expose a public getter, get tooltip().

Basically I have 14 text boxes, each box draws its content from an external txt file. Next to each text box is a button. I want the button to be either visible=true or visible=false depending on weather or not the text box has content or is "undefined" Here is what I have so far, and it's not working:[code] I would like a FOR loop to just run through the variables and check to see if any of them are undefined. if it is, then make the correct send button invisible.
View 8 RepliesIf I skin a button and use the AS3 graphice.clear() and graphics.lineTo and beginFill to create a shape, the button overlaps other items in the container.

I've got a spark list that gets dynamically filled.So far the new items appear at the bottom of the list. What I'd like to do is to add them at the top.The items in the list have a unique ID so some kind of sorting mechanism would probably do the trick as the new items have a greater ID than the old ones.What I'd like to avoid is some complex method behind this as I'm working on a mobile platform and the list can get quite big so I need this to be as efficient as possible.The list's data provider is an ArrayList that gets updated using binding.

View 2 RepliesI was wondering if anyone had access to source code that would allow me to draw lines between objects. I have examples of the standard one line between 2 objects.
What I'm looking for is an example of how to draw a branching line. I.e. Starts as a line coming from an object and then branches out to other objects. I don't want to draw multiple lines from the same object because I need the objects to be related and the lines to have a settable property.
The added issue is that I want the number of branches available to be settable by the user. But if I can find code that dooes the branching lines, it probably wouldnt be too hard to tweek.
I am drawing some lines in my program using
graphics.lineTo(xx, yy);
The program has a background image over which these lines are drawn.The problem which I am facing is that the image overshadows the lines and the lines are not visible to the user.Since these lines do not have an id, I am not sure as to how I can assign a depth to them?
