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?
If 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.
When I use the and mxml to create the same shape, the button is neatly positioned inside the container.
I wanted to check if there is a easy way to build an arrow for a line... currently I am trying to draw a triangle at end of the line- doable but a load of geometry to handle as the line could be at any angle and- anything build-in available?

is it possible to align the stroke of a graphic with actionscript? for example, the following code creates a black rounded rect with a grey stroke that is automatically centre aligned.
var t:Sprite = new Sprite();
t.graphics.lineStyle(5, 0x555555);
t.graphics.beginFill(0, 1);
t.graphics.drawRoundRect(25, 25, 200, 75, 25, 25);
t.graphics.endFill();
the lineStyle function doesn't seem to offer any built-in functionality for aligning the stroke. in Adobe Illustrator, you can align a stroke to be either centre (half in/half out of the fill), inside (bordering within the fill) or outside. (bordering outside the fill).
How can I Tween drawing a line mc.graphics.lineTo(); ? I just see tweener has an onUpdate property awesome.
View 0 RepliesI have an application that creates a chart dynamically. This chart has a lot of information plotted on it (4-6 stock trends). I want to be able to toggle some of those lines with a button. Each trend is drawn with something like this:
Code:
// establish a new Vector object for the commands parameter
var line_commands:Vector.<int> = new Vector.<int>();
line_commands.push(1,2,2,2);
// establish a new Vector object for the data parameter
var line_coord:Vector.<Number> = new Vector.<Number>();
// use the Vector array push() method to add a set of coordinate pairs
line_coord.push(0,0, 75,50, 100,0, 125,50);
graphics.drawPath(line_commands, line_coord);
How would I toggle the line I just drew? My first idea would be to put some of this code inside a function and redraw the line with the same color of the movie's background color. I don't know if this is the best option, I was wondering if I could draw this line inside a Sprite or Movie Clip and just toggle its visibility?
I am trying to draw a line from x1, y1 to x2,y2 and i want it to be a line that repeats a pattern from an image. All I can see is that you can only draw lines and change their color or thickness but I would like it to repeat an image. Is that possible or do i have to use a really long and thin rectangle with a bitmap fill?The problem is I am making a game where the user will be able to actually draw the line so i have to make it be created dynamically. The game fantastic contraption [URL] has in the game a feature where you draw lines of any length and position that are filed with a picture.

View 2 RepliesI have an image gallery which loads a detail image, then draws a line next to the image on one side based on image dimensions. Clicking on the image returns one back to the main image thumbnail list, then clicking a thumb loads another image into detail holder. Everything works fine with it, except that the lines, rather than disappearing upon detail image unload, accumulate. Is there a way to clear the contents of the lineDrawing MovieClip without removing it from the stage, so that I can draw a new line in it? I've tried removeChild on the MovieClip, but then the lines disappear entirely, same with placing lineDrawing.clear() at the top of the setupDetail function.
var detailImage:Loader = new Loader();
var lineDrawing:MovieClip = new MovieClip();
setupDetail();

In the script, sometimes a newline is added in the beginning of the text field (am using a textArea in adobe flex 3), and later on that newline might need to be removed. I was wondering how to check if there is a newline at the beginning of the text field and then how to remove it.
View 1 RepliesI need to replace multiple contiguous new line/line feed characters in flex with a single new line character.
Example:
The string

Should be converted to
"My name is blah blah

"
Hope the example makes it easier to understand.

I need to read a large CSV file (8-15 MB) and generate a LineChart in Flex AIR. Since Chart need data in structurd format like XML. When I read CSV and convert it to XML object 8 MB file size become 24 MB XML object and not able to graph.
Best solution is to read Line by line and read only part of data. How can I acheive this in Flex AIR ? Is it possible to read line by line in Flex.
Otherwise what are the best ways to draw a graph in FLEX using large data.
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 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
how do you know the parameters (eg height and width) of the element, if the constructor is passed only his Graphics?
View 1 RepliesI 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);
