Actionscript 3 :: Reloading A Component But Maintaining The Same Instance In Flex?
Jun 14, 2011
I have a canvas component called myCanvas and I instantiated it with
var myCanvasPage:myCanvas = new myCanvas;
this.addChild(myCanvasPage);
Then I want to essentially reload myCanvasPage later on. In effect I want to do this:
this.removeChild(myCanvasPage);
var myCanvasPage:myCanvas = new myCanvas;
this.addChild(myCanvasPage);
except instead of creating a new instance of myCanvas, I want to use the already created instance of myCanvas and essentially reload or re-create it but making sure that the instance name and references to it remain the same.
Is-there a joomla compenent that permits to integrate a flash SWF on a joomla website : without realoding it for each page (by using an IFRAME or anything else
I have various custom component instances in my flex app. I want to loop through them recursively and get their instance Ids. The recursive part is very important to me. I have tried doing this, but it didn't do recursive:
for each (var myItem:* in this.MasterContainer.childDescriptors) { trace(myItem.id); }
I have a flex application where on creationComplete i call a method in which i needed to load two XML files frm the server.only after which i need to proceed further..
Currently i am doing the following onCreationComplete = init();
private function init():void{//loading first XML urlReq = new URLRequest(PATH_FOR_XML1); urlLdr = new URLLoader(urlReq); urlLdr.addEventListener(Event.COMPLETE, doEvent);
I have a flex application that has a home button. I need to reset the application when this button is clicked. I can't use navigateToURL or ExternalInterface.call("window.location.reload"); as its not acceptable to reload the swf file.
i have a TitleWindow popup which opens a videoDisplay to play a video when i click on a thumb.What i want is my popup to resize and the video inside it but to maintain its original aspect ratio and not stretch.[code]
i have searched a lot but could not find the exact way to do this. you will understand better if you will look once this page. freescale. open this in IE.Here is my scenario... click om power Actuation present in leftnav under Analog & Power Management. you will get result table and above that i have a container which shows different filter criteria. now find a filterable header(match header name with filter header) that is out of the screen fold to the right.then Choose a value for filter exercise, filter by it. now here my problem arises after reloading the results, the table-view comes back to it's starting position, which creates the confusion to end user about the results.
I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
I have 3 insances of the button component on stage named 2_btn, 3_btn and 4_btn.They all are broadcasters and have been initialized.I want them to broadcast an event and pass a variable along each time they are pressed.[code]
- I have two textArea components on the stage - I need to figure out what textArea component is in focus when clicking on it
How do i make it so that it can figure out the instance name of the text area component in focus so i can preforme some code? I tried the following code but it doesn't seem to work.
I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.
I would like to bind two components with out binding and which resides in different MXML.for eg: A.mxml has textinput and B.mxml has a combobox when choose one item in B.mxml selected item should be display in A.mxml textinput.
I have a base class which is being created via remote_object [RemoteClass alias] from the server.I have other specialized classes that are derived from this baseclass, but serialization with the server always happens with the base class.The base class has meta data that defines what the derived class is, for example
[RemoteClass (alias="com.myco...')] public Class Base {
Is it possible to define the scenes and the frames in XML in Flash CS4, so that we can parse it in actionscript 3.0 and define the interactivity. I want to define all the UI elements and the event associated with UI like List control or button in XML format (XUL??) and then use actionscript to build the application logic. Are there some good examples?
I am creating a site in flash, and I have always had this problem when I make flash sites. How can I eliminate a scroll bar in the browser, and make the swf fill the entire browser window no matter what? Is it something I need to write in Actionscript? the HTML page?
the situation | an instance of the DateChooser component reads an xml file which houses info for homework assignments and their due dates. if there is a due date, make sure that date is highlighted on the DateChooser component. from what i've been told, the xml file stores urls which will tell if there is s/thing due on a particular date. the xml file | very simple, has an <activity> element with a 'date' attribute, i.e.
[Code]...
my remaining questions | What needs to happen as soon as the xml file is loaded? i.e. do i call a function which parses the xml data and puts it into an array? then the DateChooser component iterates thru the array looking for boolean values noting if there is an activity or not and if so, on which day. if it finds one, it sets its highlight property to true for that particular day. i'm setting up the xml file correctly.
Does creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
What I want to do is to fill in a movieClip with information I get from the MySql database and then maintain that MovieClip throughout the site which has swfs and web pages. how it is best done and easiest? Would a FlashVar have to be used? Could I just load something and have it stay inside while everyone accesse it?
I've got an algorithm that takes more than several seconds to complete. I'm trying to implement it into a 60fps flash game i'm creating. I am wondering if there is some provision in ActionScript3 to interrupt a computation in order to update the frame and continue the computation afterwards. There probably isn't, so I'm assuming the best method would be to perform the computation for x milliseconds, measure what the frame rate is after, then adjust the time the computation will run for next frame if the frame rate is less than or greater than 60 fps. The drawback with this is that the game won't run at a steady 60fps...
Any other ideas on how to (optimally) perform a large computation in AS3 while maintaining the framerate? EDIT: For the curious (the calculation, perhaps I should have said algorithm): I'm creating a motion planning library for game AI objects (one use for motion planning). The algorithm is along the lines of a RRT (rapidly exploring random tree) that iterates thousands of times. Demo link:[URL] Click to motion plan. The circle can "thrust" at a fixed magnitude in any direction. Also - there is no linear velocity damping (i.e. friction).
I using FlashMX to read in a value from an ASP page into a dynamic text box. This works fine.
I then use a motion tween animation to tween into another image, and there I put another instance of the dynamic text box, with the same name, but the value doesn't populate the text box. It's as if it reads the variable into the text box, but if I do anything to the text box, it loses the variable and can't get it back.
Further, if I switch back to the first frame, the value won't populate either, I have to refresh the browser page to repopulate the variable (read the ASP page again.)
Is there a way to maintain this variable throughout the movie, so that I can re-use it?
I am working on a paint application, I am able to draw lines, draw shapes, erase. I need to implement undo and redo functionality. I plan to store history in a bitmap and put it in an arrayMy question is whether we can have an alternate solution other using bitmap class. How can I store coordinates of non straight line without using up lot of memory and processor.

I'd like to use a button within a component to remove it. So, you click it and the component is gone. But, I haven't figured out how you reference the component from within the component. What should I put in click=""?
A Flex components values are initlized by init methord. In an application flow, How to refresh a mxml component data value ; as init is callled at the start up it self only.
eg. of mxml componet may be as simple as button label or text as complex as repeater whose data provider is a web service ( means a fresh quesy should be made to pull the data and refresh the dataprovider of repeater )
I have a project which, for all intents and purposes, attempts to create an online text editor/word processor. The key thing is that I need all multi line formatting to be retained and sent to the server. ie, if the user enters a bunch of text (all colors/bold/fonts and stuff are working great) which has a carriage return or a line wrap, I need a way of tracking that and inserting some kind of flag to let the server now to break to the next line at that point.this project is a client/server application so just storing the text string and expecting flash to be able to use the same size text box will not work.
I have created a function that detects keypresses and MOSTLY takes care of the carraige return issue (still not as solid as I'd like though). Basically, every time the user presses return, I store the length of the string and, when parsing the data for transfer, I insert newline chars at every index point where one is needed. This mostly works unless the user goes BACK and enters a return (still working on that little issue).But the word wrap part is killing me. I did find several discussions of using either total characters to determine how big the box is and where to break the line, or something along those lines, but here's the main issue with that:everything is dynamic. the user can change almost everything, from text font (so there will be variable font widths) text size (again, variable widths) to textbox size (so I can't go with a fixed pixel size to break the text). I've noticed that it was very easy to make a text box vertically dynamic, but the width seems to want to stay fixed (if set to multi-line) since the user will be changing this width, I'm just stuck.
if it means coding a huge set of functions that compares every possible font (i will be using embedded fonts eventually so they will be limited) with every possible size and then using that data to determine box size, that's fine, I'll do whatever I can to get this working, but there just has to be an easier way
I have recently purchased Pageflip 3.6 (http://pageflip.hu/) for a project at work and what I am planning on doing is implementing a guest book which i have created in flash.The guest book I created consists of a file upload (for images) a comment entry and a signature section (where the user has a choice between a bunch of fonts and writes there name) which are located on the left page of the flip book and then on the right page it displays the post (using XML).
Now the guest book on its own works like a charm, but when it is called into Pageflip the buttons for the upload/submit stop working and nothing happens.The way Pageflip pulls in the swf/png/jpg to fill its content is through an XML file.Pageflip does have hot spots and controls to switch pages directly within the book but I have disabled them so that you can only switch pages through the control bar, as I thought the hot spots were conflicting with the input for the guest book but it didn't do anything it still will not allow me to use the controls for the guest book.
I know this might be kind of confusing I hope i described my problem clearly enough and any help or input at all would be fantastic. I'm fairly green with actionscript but i'm the only one at my agency that knows how to use it so its tough on me to do these advanced things without anyone to bounce ideas off of
I'm developing an iOS flashcard app in Flash CS5 for a school project. I've got over 600 scenes, and my cards are structured in pairs so that one scene is the front of the card and the next is the backside with the answer. I've figured out how to get from scene to scene, but have had no luck trying to find how to randomize scenes while keeping them in pairs
