Actionscript 3 :: Adding Drawing Objects To A Collection In Flex 4?
Aug 4, 2011
I'm trying to make annotations on an image. I want to store all these annotations into a collection so that I can later remove or edit particular note(annotation).I'm creating a UIComponent instance for example markUp and doing
When I get a collection back from the service tier, I create an ArrayCollection and apply a sort. When I add an item to the collection later on, the sort is still in place? It seems to be the case. I thought I was only sorting it once, not applying a sort that will stick??Here is the method for adding an item:
private function onAddNewClick():void { var fileTemplate:FileTemplateDetailDTO = new FileTemplateDetailDTO();
For example in Java you can do:List<Person> where Person is the object type.In AS3/FlexArrayCollection which takes any object type. Is there any way to create a list/collection of declared objects in AS3/Flex (or is it impossible due to weakly typed language)?
May I know what is the proper way to keep track of display objects created and hence allow me to remove it efficiently later, for garbage collection. For example:
for(i=0; i<100; i++){ var dobj = new myClass(); //a sprite addChild(dobj);
I am using Flex 3 and make a call through a RemoteObject to a Java 1.6 method and exposed with BlazeDS and Spring 2.5.5 Integration over a SecureAMFChannel. The ActionScript is as follows (this code is an example of the real thing which is on a separate dev network);
LinkeSetFx has its own CollectionEvent, but I don't know how to map the LinkedSetFx event to mx.events.collectionEvent(I want use it in ComboBox). LinkedSetFx is in AS3Commons-collection framework.Here is the url, choose the as3commons-collections-1.0.0.zip, you'll find LinkedSetFx in srcorgas3commonscollectionsfx
I need to draw on stage about 40,000 4x4 squares each a different color. The color is determined by an xml file. I have this working in as2 and have converted it to as3 the problem is the amount of time it takes to draw is causing cs4 to time out. I have extended the script time out to 60 seconds. In cs3 as2 it would draw the squares in about 15 seconds. I was hoping as3 cs4 would improve performance but seems to be the opposite. I have tried several methods such as adding children and various drawing variations. the bellow seems to work the best, but is still causing flash to crash.
I'm developing a touchscreen application in AS3, and I havesome problems because the applications reaches 1,5 Gigabyte ofmemory if it's keep running for an hour.this memory size is because I show some videos in streaming,one after another (not in the same), and then they are not garbagecollected: I set the references to the videos to null and I removethe listeners, but flash seems to keep them in memory. I tried todelete the code section about the videos, and I have no problemswith memory (I also load some external images with the videos), soI'm pretty sure they're guilty in some way...I read that there's a bug in flash so displayobjects are notgarbage collected even if you remove the pointers to them: is it
I've been in a trouble with "removeChild" for a while. I know there must be some great discussion around but just could not find some nice posts in details.
Just curious, If i nest a movieclip inside of another movieclip, and the nested movieclip is attached to a custom class. And that custom class has a Event.ENTER_FRAME listener. when I destroy the container movieclip, will flash get rid of the event listeners inside of nested movieclip's custom class ?
May seem like a silly question but flash has a tendency of not killing listeners along with the movieclip itself once it is removed from the stage(this is if your apply the movieclip via addChild). and its a hastle when things get too complex. My solution was to create a single loop for all my objects. Now ive come to a point where I am probably going to have to nest some movieclips inside of another so the position of the nested movieclip stays relative. the parent movieclip will be rotating and scaling so I rather nest it. But I got to know how flash handles moveiclips that are nested into a parent movieclip and has enter frame listeners.
In my flex application im using two datagridfirst datgrid is for items collectionssecond is for bank details.if i click one row in first datagrid (which has the items collections)...a unique code is taken from the grid(which is primary key).then, i have to select two or more banks using itemrenderer checkboxes in second datagrid(which has the bank details)ow, have to bind the bank details(one or more banks) with that one primary key in first datagrid. to an single array collection... and have to show it in another new datagrid(thirdone)
I'm trying to construct an animation illustrating the angle of a circle.The user types in a value and the handle gets rotated on a timer tick. (Press Enter or the ndra-button to see the effect): Example So far so good.Now - my problem is when the rotation gets bigger than 360 degrees. I would like the arc's alpha to get darker, to see it draw upon the "existing" arc line. But I don't know how to do that and I can't find code for doing it, either.[code]The DrawingShapes.drawArc method comes from here.If anyone could point me in the right directon on how graphic updating works. I tried not removing the lineHolder from stage when it's updated, but that just made the line's alpha 1 instantly. I would like it to "gradually" get filled in when the arc exceeds 360 degrees.
As the heading dictates, i want to place bitmap files on the faces of the 3D object that i have created.Basically i found this tutorial code on a 3D rotating cube that is able to be rotated by the mouse. I have modified it to change its shape from a cube to a 'plane' or rectangular style object.
Code: var vertsArray:Array = []; var facesArray:Array = [];
I've made most of my application now, which allows the user to draw on a canvas, I'm just not sure on how I would go about creating a button which allows the user to switch to an eraser, or what code I would even use?
the first thing I am doing is to draw a shape. Object Drawing is selected. I have clicked the rectangle shape tool, have selected a color and fill. I drag across the stage and a rectangular line appears, but when I let off the keys, it dissapears. No shape, no stroke, no fill.Invisible, gone, disappeared.What the heck am I doing wrong?
when drawing an object and using that objetc to mask another layer im having trouble making more than one object act as the mask. Eg I draw a circle and use the mask function to mask an image, works fine, then i draw some more geometry (in the same layer) and it will not mask as the first object did. Is there any way I can 'Join' them togeter to act as one big mask?
I have a vector drawing object inside a parent movieclip.The drawing object is acting as a semi-transparent frame for and image on another layer. the problem is when I scale the parent movieclip the thickness of the drawing object is changing.I know that you can turn off scaling for lines and rectangles, but is there a way to do the equivalent for a vector drawing object?
I'm trying to make a short script in AS3 which will simply take some animated lines that are in a movieclip (pre-animated in library) and draw a 15px diameter circle around each vertex / point of the lines.
how to access the vertices of the lines in actionscript!
I have imported a lot of paths from an Adobe Illustrator document right into a flash file. The paths exists as Drawing Objects inside the scene. Using pure actionscript, how can I move a symbol following each of the lines, without using predefined Motion Guides.
EDIT: I've attached the Flash file, full of drawing objects.
http:[url]....
The question is: Are these drawing objects accessible through AS3 or I should convert them to symbols / whatever format necessary.
I have a little problem with counting all elements on stage. Flash, unfortunately is counting all objects on the stage without drawn objects (all shapes, including drawing objects, rectangles etc) all missed. Is there any way to count them?
This seems like it should be fairly simple, but for some reason Im getting caught up when it comes to removing a layer from my drawing app, and when moving the layers up and down in the display list. My first problem is that when I do the (canvas.removeChild(layers[value]); it removes the child of the targeted layer, but it also removes the child of the objects before it? I think anyways.
The second problem is that my layerUp function works, but my layerDown does not, even though they are the same code? Confused I am indeed. I'm sure its fairly messy since Im just learning this stuff, so sorry for that too!
I have a set of small circles(balls) on the stage, contained in an array. The array at different times in times in the program could have ballArray.length=1 or ballArray.length=125 or 48 or 0, etc.The balls float around the stage randomly too.I wish to have a function which will draw a line between all the points(balls or circles) in that array.So for example where there is 0 or 1 balls, there would be 0 lines drawn.Where there is 4 balls there would be 6 interconnections. as there would be six lines linking every object to each other object , exactly once per tick in the animation.[code]
How can I draw objects relative to one another in AS3? For example I have a small object in the middle of a large object. Then I move the small object to the left (subtract x) but visually I see the large object move to the right and the small object stay still.
I've written a small program which detects my mouse movement and draws circles on the x- and y-position of the mouse.
[Code]....
As you can probably see: after drawing a lot of circles the program slows down and the framerate makes the circles be placed with a large gap between them. I would guess that the program draws what is behind the current circle even though the user cannot see it?
I have created some graphics directly in Flash Cs4 using the drawing tools, making them 'drawing objects', yet they are pixelated when viewed in browsers. Within Flash they look crisp, but not when exported.
So I've got problem with some drawing objects inside movieclip in my flash file... Setting width and height of flash to match browser's w&h got my movie clip to get correct values, but unfortunately drawing objects inside of it are not scaled as movieclip. Those object are just random stripes that got some tween on it acting as somekind of preloader... All graphics are pulled from ai file, so no AS was used to manipulate them, just pure tweening in design mode...So if my stage w & h are lets say 720 x 50, graphics inside movieclip are 1600 x 900 which match my monitor's resolution.
