ActionScript 2.0 :: Add A Listener But Nothing Happens?
Jun 18, 2008
I tried to add a listener but nothing happens....I mean nothing happens.
keyListener.onKeyDown = function() {
if (Key.isDown(Key.TAB)) {
if(des.text != "FRED"){[code]...
We want to set focus in atext field then when the user presses the Tab key we want to see what's in the field and move on the timeline.When I put the code above into a new file it works fine but if I put it into my course file or even bring it in using a loadmovie it doesn't work anymore.If I use a simple on realease key = tab on a button it works in a new file, but not in my course file.
TypeError: Error #2007: Parameter listener must be non-null.at flash.events::EventDispatcher/removeEventListener() at project1_fla::MainTimeline/btnName()
I am having a weird problem with scope/reference. I am using a loop to preload a number of thumbs in one go, I am creating a different listener for each one on the fly and then passing event handlers for each one of them. This should not be difficult using a loop, but somehow I cannot access the the parent object on my listener and therefore I can't do much with my thumbs after they are loaded.Here is the relevant segment of my code. myThumb_mc is a temporary variable that does not exist when the loop finishes, you can copy and paste this code to test it though. It should work to that extent. (you'll need an image1.jpg to be in the same directory)
Code: var myThumb_mc = _root.createEmptyMovieClip("myThumb_mc", _root.getNextHighestDepth()); myThumb_mc.clipLoader = new MovieClipLoader(); myThumb_mc.clipLoader.loadClip("image1.jpg",myThumb_mc);[code].....
The code above works, but it does not look nice and it cannot be the right way of doing this. Long question short, how can I access the parent of a listener from a listener object? ._parent does not work.
This is something that tugs at my mind a lot so I figured I'd ask the community. If I have a class called MyParentWidget and it contains an instance of MyChildWidget with an instance name of myChildWidget then I will often do something like this:
Quick question, can an object get the same event listener applied more than once? For instance if I have myObj.addEventListener() and then later in my application I apply the same exact listener on the object again does the listener get applied on the object thus increasing memory consumption? or does it get re-written over?
I am trying to add a key listener. I'm pretty sure this was working recently, but now it isn't, and can't figure out what is preventing it... I am saving in Flash 6.
var myListener:Object = new Object(); myListener.onKeyDown = function() {
I want to add a key listener to my stage, but from an object 2 depths below the stage. How would I do this?
I thought about adding the listener from my doc class, but the listener function is in the object that is two depths below the stage, which would mean I would have to pass the key values to the next movie clip, then when that one is loaded, pass it to the one with the listener function. It seems very complicated, is there an easier way which keeps with the principle of OOP?
I have created a listener. I want to call this listener on click on the button. As like my_btn.onRelease = function(){//call this listener on click on the button.}
i've a problem with the DOUBLE CLICK EVENT. I have a foregrounded MC, named AA(activeArea),who stands like a "event captor" covering the whole stage area, so i used it for manage every event in my swf.The problems starts when i add a listener to the MC which stands on the background, under the AA. It doesn't "listen" anything.
I have a timeline with some button (and movieclip) that will appear later ...what is the best way to add listener to them? I can't do it in the first frame because the buttons don't' exist yet... Is it a good practice to add the listener when flash put the buttons on the screen or is there a better way yo handle this situation?
I'm not getting any errors. I've been over this code again and again. I based this on an exercise from Lynda.com. The code includes listeners for mouseup but the dragged object doesn't stop dragging when at mouse-up as directed. Also, the dragged object doesn't return to original position as directed.
Here is the main .as file:
Code: private function checkTarget(event:MouseEvent):void { if(event.currentTarget.hitTestObject(event.currentTarget._targetPiece)) {
I have a document class called "RheDocClass.as". This document class instantiates a class called "LiquidGui.as".What I want to do is have the LiquidGui class listen for stage RESIZE events and the act on those events. But when I try to add a stage listener to the LiquidGui constructor I get errors. ( the error depends on how I experiment with the syntax) So I have put the listener in the RheDocClass instead, and then pass the stage properties to the LiquidGui class. But, I'd really like to keep the stage resizing code all in the LiquidGui class so that I can reuse it with other projects.how I can attach a listener to the stage from the LiquidGui class?
I've got a shell movie clip which loads some other clips. In one of the sub clips, I have a key listener. Inbetween loading of the sub clips, I have it removing the key listener and the movie clip.
But the function that was attached to the key listener is persistant, even after the sub clip has been deleted, and I've attempted to remove the key listener from the main shell. What ends up happening is the second time you load the sub clip, it runs the function *twice*, or three times, or as many times as you click the link to load it.
When i run the shell movie, it shows trace actions from the sub clip even after it's been removed!
Within flash 8 i'm working the folowing website:[URL] The centered MC size changes when clicked a button.I published the movie as a 100% x 100% with a noscale option. I want to add a movieclip in my main timeline wich must go automatically to the left of the users screen. if you got 1024x 768 and even when someone got a nice 30" screen from with a resolution from 2560x1600. yesterday i posted a thread and i've got the next code wich did not work in my movie. the next code i placed in my main timeline:
I tried several things today but nothing works. i tried different publish settings. the listener option was new for me and i tried to find out what it does.do i need to add a line like addListener? or do i need to name the function?
I'm building a center stage object and I wanted to know if there's any way to add a event listener that checks if the children have changed in size.[code]This seems like it should be available but I can't find a reference.
I'm trying to set up a keyListener that would activate and deactivate under certain circumstances. For instance, it needs to deactivate if a key is not pushed a short time after something unrelated happens.In order to do this, I'd need to have the removeListener method outside of the Listener function, but it doesn't seem to remove anything when it's not in the function. Is there something else I can do, or am I doing something wrong?
I have a simple roll over animation. After the roll over, is there any way to disable the event listener so that the animation will play completely before any further interaction happens? Then re-enable it so it can be rolled over again? [code]...
Can't figure out why I'm getting this error:Error #2007: Parameter listener must be non-null. I have traced the xml, so I know the values are loading, so don't know why I"m getting a "non-null" error.The first value in the xml traces correctly, but then the error occurs.I only receive the error when I pass the popup argument to createImageHolders, and I don't know why... I"m a 3.0 newb.
I keep running into problems where I want to add an event listener onto a class instance RIGHT after it's instantiated, like this: Code: storiesXML = new XML(XMLdata); storyBook = new vStories(XML(storiesXML.stories)); storyBook.addEventListener("storyBookLoaded", storyBookLoaded); . . .
But by the time we arrive at the third line, the "storyBookLoaded" event has very often (inconsistent) already been dispatched from my class instance: Code: var evt:Event = new Event("storyBookLoaded", true, false); dispatchEvent( evt ); ...
(Even though quite a lot has happened in the class before that.) To be clear, I don't want to add storyBook as a display child, and even if I did, the addChild() method would have to be called after instantiation of storyBook, so we'd have the same problem. I know I could set a timer in the vStories class to artificially delay the dispatching of the event, but that seems really hack-ish, and would have a real compounding problem if I have to do it too often as everything builds up. How to make sure custom communication events happen after their listeners are set?
I have a rollover function that sets alpha values, and i also have a click function that sets the alpha even higher on click. I also have a roll out function to return it to normal when roll out. The thing is i want it to hold the high alpha value on click because that is the web page is selected. It works, but the second i rool out or roll over, it sets the value back. [code]...
