ActionScript 3.0 :: Safely Switching Focus During Backspace Key Down Event?
Sep 1, 2008I have a simple form that I'm building. It has a variable length list of entries, and I'm using a TextInput for each entry.
Because the list is variable in length, I'm allowing the user to delete elements from the list. One of the ways they can do this is to press the backspace key when the cursor is in an empty TextInput. I am handing KeyboardEvent.KEY_DOWN and checking for the backspace key, to accomplish this.
The problem I am having is that after I remove the deleted TextInput, I want to leave the focus in the TextInput above. I can do this using 'setFocus', and that works fine, however it seems that the backspace is still processing, and so after the focus is set, the content of the TextInput is delete which I don't want.
To get around this, I've created a one-shot timer with a 0ms delay which changes the focus after the KeyDown event has completed.
My workaround is successful, but feels very heavy handed. Is there a better way to achieve the same effect?
IDE :: AddEventListener RemoveEventListener?
Feb 7, 2010I have made the flash file into CS3 and simplified the idea a bit. Basically I want to click the box on the right to start playing the song and the spectrum and then if I click it again it will stop playing the song and the spectrum then if I click it again it will start playing again ect ect. I could not upload the song.mp3 cause the file size was too big you will have to replace it with another mp3 in the root of the folder and name the mp3 song.mp3.

Professional :: Fl.removeEventListener Broke In CS4?
Apr 27, 2010I'm having issues removing event listeners once they're added in cs4 jsfl. I tested the same code on cs3 and it removes the listener just fine without errors. In CS4 if I try:fl.removeEventListener("mouseMove", movieclipListener);I get the error:removeEventListener: Argument number 2 is invalid. If I try:fl.removeEventListener("mouseMove");I get the error:Wrong number of arguments passed to function "removeEventListener".
So I'm summarizing that: - the removeEventListener has changed between versions cs3 and cs4- Neither method works in removing my event listener Tried running this in the same script that added the event listener (same script that contains the function called), tried running in a separate script. Same errors.

2. After removing the event listener, I still get output from hasEventListener

3. Event listeners like Event.COMPLETE are events that happen once, then not again. One would think these kind of events also would delete its event listeners. Is this so?

ActionScript 3.0 :: Movieclip RemoveEventListener 'remembers' Clicking
Feb 5, 2010I'm not very sure how to explain my situation... In short codewise: I have a movieclip that listens for a click-event, set trought addEventListener. At a certain point I 'addchild' a button to that movieclip AND disable the eventlistener of the buttoncarrying movieclip. (the button is over the movieclip on the screen, and clicking the button must NOT trigger the mouseclickevent of the parent movieclip.)
when clicking the button, i need to do some actions (works ok) AND get the movieclip listening to NEW clicks. But from the moment I add the evenlistener to the movieclip again, it seems to 'remember' the OLD moueclick meant for the button. That's what I can't have, I start to think that I need to flush a clickingbuffer belonging to the movieclip or something... Now in words: It's about a minimized login-window (=movieclip), that needs to maximize when clicking on it (anywhere on the window). When maximizing I add a form and some buttons. When clicking my "cancel"-button I want to minimize my login-window again and let it listen for mouseclicks again so we can maximize it again..

ActionScript 3.0 :: RemoveEventListener - Remove All The Listeners In The Class
Jan 29, 2009I have a mc that i use as a button. I have an external class that controls the button and adds interactivity to it, here's part of the code:
[Code]...
The problem is, i want the btn that, when clicked, remain inactive.That's why I remove all the listeners in the class. HOWEVER, it still functions as a button, I mean the functions haven't been removed at all after I click it. What's wrong here? Why are the functions still there, if I have removed them when clicked at the btn?

ActionScript 3.0 :: RemoveEventListener / Disable Button During Tween
Sep 25, 2009Basically, I have a movieclip on the stage called slide_mc that gets tweened left or right when next_btn or back_btn are pressed. Slide_mc is a long rectangular strip that has different images on it. The idea is, you press next or back to show different parts of this strip. There are two panels on a layer above it to hide the extra parts of the strip from view. I needed the slide_mc to move forwards and backwards seamlessly as if it is one long continuous strip. I did this using actionscript3 and its x coordinate. The images on slide_mc are equally spaced so I just set the tween to move by a certain number of x values.
The problem is if you press the next button before the previous tween has finished it progresses again by that same value which ends up moving the slide_mc to a random position, perhaps covering some of the image. How can I disable the next and back buttons until the Actionscript tween has finished what its doing and then enable them again for the next tween? The end product is supposed to be a gallery. Obviously it would be better to use a UiLoader to display the images to keep the file size down, but I couldn't think of a way to load the right images while still allowing the slide_mc to move forward and backwards.
Here's my code:
next_Btn.addEventListener(MouseEvent.CLICK,moveLeft);
back_Btn.addEventListener(MouseEvent.CLICK,moveRight);

import fl.transitions.easing.*;
