ActionScript 1/2 :: Button Component Breaks Tabbing?
Jun 15, 2009
I'm building a complex movie using MX2004 and ActionScript 2. Problem: I can't get text tabbing to work, no matter how closely I control the situation using tabIndex, tabEnabled and tabChildren.
While working to simplify a reproduction case, I've ended up with a movie that works, just having four Input Text TextFields hand-added to the timeline, no code involved. But, when I drag a Button from the Components window to the library, tabbing breaks. This is without even placing the Button on the timeline. Remove the Button from the library and it works again. Needless to say my project uses Buttons, and I'd rather not have to re-implement them.
Let me say it again. In a generic, timeline-based movie with no ActionScript included, tabbing works between Input Text fields. But the mere act of adding a Button instance to the library, without the Button ever appearing in the timeline, breaks tabbing. I'm flummoxed: why would something being present in the library, without any appearance in the time line (nor any Actionscript to add it), have anything to do with the movie's functionality? True, adding the Button increases the size of the published .swf from 177 bytes to 27kB, but why would it break things when I'm not even using it?
I've attached the broken movie. Open it and test it: tabbing won't work. Delete the Button from the library, test again: tabbing will work.

This script is straight out of the ActionScript 2.0 docs. It works as advertised when it is on the root level stage. But if I put it on a tweened layer (so I can move it onto the screen with some other stuff), it no longer works. Anybody know why and how to make it work?

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 a small movie with a stop() on the last frame to prevent the movie from looping. On the last 10 frames or so a button appears that when clicked, goes to an external web site. The button will work until the timeline hits the last frame with the stop(), and at that point no longer works. The user is left sitting at the last frame of the movie, trying to click a button to visit another website and nothing happens.I have the button's actionscript in a separate layer starting from the same frame as the button (named buttonMBP) appears in the timeline:
Code:
buttonMBP.addEventListener(MouseEvent.CLICK, urlJump);
function urlJump(event:MouseEvent):void{
if(event.target == buttonMBP){[code]...
If I add trace commands to the function, I can see them work as I click the button when the last 10 frames are playing, but once the last frame appears with the stop(), everything goes into a dead stop. I guess the stop() stops everything and not just the timeline? I'm fairly inexperienced with AS3 (trying to learn).Is there a better way to have an active link appear on the last frame of a movie? I went with using a button because the standard text-tool doesn't support a mousehover (or not one that I could see) that would indicate that the text was an active url.

I've got a Next button with a rollover that works fine. However, when the user reaches the end of the page, the button needs to flash to let the user know they need to click it.
I set this up the way I would have in AS2, with an up state in frame 1, rollover state in frame 2 and frame 3-10 has the animation for the flashing state. In AS3, as soon as I put the animation in, the rollover no longer works and I think it's tied to my animation layer since it works if I remove that layer. I tried putting the layer under my normal button layer, thinking it's not recognizing the animation as part of the button. I tried using classic tweens and the new tweens and nothing seems to work...
I attached the file. You can see that the rollovers work, if you click the pause button, it triggers the flashing animation and then, I get the following error if I try rolling over:
TypeError: Error #1010: A term is undefined and has no properties.
at buttonRO_fla::MainTimeline/BtnIn()
and tracing the target name no longer shows the button name (as it does before you do the flash)...

I have a preloader bar and percentage in my first frame.Once it has loaded, it goes to frame two.Frame two contains a "play" button that sends it to frame three, where the actual movie begins.I managed to script the preloader without a hitch.However, when I added the button script to the second frame, errors appeared in the preloader script.[code]

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=""?
My component: popCanvas
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Panel width="200" height="200" title="hello"
click="remove=">

So I've 2 buttons and I can tab between them like this:
Code:
butt1.tabIndex = 1
butt2.tabIndex = 2
Simple. So now I drag a combo box onto the stage and nothing tabs anymore!
I can then set the combobox to be tabbable but the mc's don't tab anymore
Code:
combo1.tabIndex = 3
The only way around this I have found is to remove the focus manager but then only the mc's are tabable again!
Code:
_root.focusManager.removeMovieClip()
butt1.tabIndex = 1
butt2.tabIndex = 2
combo1.tabIndex = 3
the only way I can see to get all of them tabable is to use "tabChildren":
Code:
_root.focusManager.removeMovieClip()
butt1.tabIndex = 1
butt2.tabIndex = 2
combo1.tabChildren = true
combo1.tabIndex = 3
but this then makes the combox editable for some reason and if I turn it off it stops being tabable again

To allow you to tab through itemrenderers in spark you simply set hasFocusableChildren="true". However when you tab to a row/tile which is not visible, it doesn't automatically scroll the List.
What's the easiest way of making this happen?

I have a form in Flash. I have the tab order set up thusly:
Code:
fname.tabIndex = 1;
mi.tabIndex = 2;
lname.tabIndex = 3;
[Code]....
Everything is fine, except the "state" field is actually a combo box component. It will tab from "city" to "state", but when you hit "Tab", it does not move the focus to the next field.
Is there some trick to this or some other code or a paramater I'm overlooking? Do I have to make a customer key listener to make it tab off a combo box?

I'm sure someone must have accomplished this before, but I couldn't find any article on this.
How can we scroll a List control (with uses an itemrenderer) to the next item, when the user tabs from the current item to the next?
I know that we can use scrollToIndex(i), but how do we notify the List that the itemrenderer has moved to the next index? I couldn't find any such event.

I'm having difficulty setting up the tabbing of some textfields after I disable and then re-enable the tabChildren property. Has anyone found a solution for this? I'll use a very simple example. I set the tabIndex of all the textfields. I test it out and the textfields tab properly. Then I set the following pseudo code to a button which will disable all the textfield tabbing in a particular MovieClip ("mcForm") and then one line later, it re-enables the tabbing:
mcForm.tabChildren = false;
mcForm.tabChildren = true;
However, the expected behavior does not happen. I expect that when I click the button, there would be no change in the tabbing, but in actuality the tabbing of the textfields are now disabled. It's almost as if the 2nd line of code that re-enables the tabbing has no effect.

I have a quiz that randomly sorts then dynamically places a question and its answer choices. An answer is a text field laid over a movie clip with a resizable, invisible rectangle and a radio-type button (not actually the radio button component) that handles the rollover and feedback. When clicked, it looks like a selected radio button if correct and has a big red X if incorrect. At this point, I remove all its eventListeners and leave it in the feedback state because the user gets to try again. It also places a feedback box on the screen with the standard, "Try again."
This all works perfectly with the mouse, but the quiz is for .gov sites, so it has to be 508 compliant. When tabbing to and clicking on an answer, the feedback button works fine, and the feedback dialogue does, too. When tabbing to another answer, however, the incorrect try resets to its up state, minus the eventListeners. I am disabling buttonMode when the eventListeners are removed, and I've tried doing all this before the feedback box is placed, as it's placed, and after the user clicks to continue. It doesn't make a difference, and neither does including tabEnabled = false; I tried not even adding the FOCUS_IN and FOCUS_OUT, and that didn't make a difference.
I could removeChild and then add it back as a new, never-been-a-button object, but if there is a simple setting, I'd like to know about it.

I have a set of 5 TextFields that a user enters info into. Each has the same TextFormat applied. If the focus is set by clicking with the mouse, the TextFormat is applied and all is well. If the focus is set by tabbing, the TextFormat is not applied and a default style for the font is seen. Here's my code:
Code:
var input1:TextField = new TextField();

Has anyone seen this before, and if so, why does it happen? [URL] Click the Contact Us form and tab from one field to another. Or fill in the "Go Black" form at the bottom of the page and tab between fields. What's the deal with that white box? Where does it come from? Why is it there? How do I kill it forever?

I am having some trouble figuring out how to work auto-tabbing between input text fields when a user inputs a character. I have a series of text boxes with maxChar set to 1, and when the user inputs a character, I would like it to auto-tab to the next one. I'm putting together a crossword-style banner ad so the auto-tabbing willtremendously. All the input text fields are instanced on the stage as input1, input2, etc; not called in from a custom class.

I have a simple form I created in flash and I set it up so you can tab from one field to the next. The problem is when I tab to one of the fields, a multiline textbox, it starts on the second line of that field. If I click on the textfield it goes to the 1st line.
The code is pretty simple:
_styleLibForm.tabChildren = true;
_styleLibForm.first_name.tabIndex = 1;
_styleLibForm.first_name.tabEnabled = true;

I'm compiling a SWF using FlexSDK 4.1. I am not disabling any tab functionality. Swf is being embedded with the following via swf object:
swfobject.embedSWF("Main.swf", "flashcontent", "984", "550", "10.0.0", params,flashvars, attributes, "expressInstall.swf");
Expected outcome when tabbing is to see "yellow boxes" on all items with click events. I don't see anything all browsers. WMODE is 'window'

I have a few textAreas (input fields) in a form.When I click on the Tab key, the focus shifts to the textArea. And along with this, a green outline comes around the textArea... How can I avoid the textArea outline color? I guess there must be a piece of AS out there which would help, it's just I did not find it and Official Docs won't say much about it.it does not happen so if compiled the movie under AS 1.0. It only has this behaviour when published with AS 2.0 (and perhaps AS 3.0 donno).

When I set up 3 input text fields, I allow the user to change the font and size of those fields. If the user selects each one with the mouse and modifys them then no problems are seen. But if the user first changes the size and font of text field 2, then tabs to that text field and starts to change the text. The font and size properties revert back to the default.

I could re-apply the formating everytime the text field changes, but that seems like a bandaid to the problem.

I'm trying to create a simple "universal" media player which presents the same user interface (or as similar as possible) for video and audio playback. Unfortunately, FLVPlayback seems not to be able to handle audio files as far as I can tell, so I'm using a Sound and SoundChannel.
My video playback is handled using an FLVPlayback component which is "wired" to standard controls on-the-fly when needed. What I want to do is wire them to the Sound / SoundChannel when I'm playing a sound so that the same UI widgets work in both cases. I'd like to avoid building all my components from scratch because the FLVPlayback component does a lot of nice stuff "for free" but it's starting to look tricky.
The standard PlayPauseButton is a MovieClip with two layers, one containing the Play button (and with the instance name play_mc) and the containing the Pause button (pause_mc). Inside one of these is a movie with some code like this:
stop();
this.upLinkageID = "PauseButtonNormal";
this.overLinkageID = "PauseButtonOver";
this.downLinkageID = "PauseButtonDown";

I'd like to learn how to use Components in Flash, and the documentation and tutorials I find are beyond my comprehension. I usually go to FlashKit and just rehash someone's code... but again, I'd love to learn how to use Flash Components.So I did a tutorial on the toggle button, but it was:1. Click button, and a window pops up at different location on canvas2. Click button again, and the same window dissapears.This is for a videogame, and I'd like a button to be click and that same button be populated with a new graphic. What I mean is, the graphic is a skull, and I'd like to have it start as a dark skull (as if a negative value) and when you click it the skull appears... click it again and it's gone (or that negative or dark skull representing it's off).So this differs from the tutorial I did because the pop-up window is the button itself, and the window that pops up would obstruct me from click it again.

I am having some issues with a php email form that I am using in my AS3 project. the form works perfect and all communication is good.however when the user is on the page and wants to tab to the next text field it jumps to one of my hyperlinks on the same page and not to the next text field down on the php form.
is there any way to stop this from happening.I have tried placing the php form on a seperate layer in a seperate mc and I have done the same with the hyperlinks .you can see what I mean by visiting this development site.(after entering go to contact)http:[url].....

I'm building an flv player using the cs4/as3 video playback component as a basis with custom buttons on the interface. I'm trying to figure out how to do rewind or fastfoward using a button instead of a scrub bar. I've seen plenty of tutorials on how to develop a scrub bar but I can't figure out a way to apply the theory to a button you hold down and it fast forwards/rewinds until you mouse off.
Obviously a mouse_down event only fires one signal and causes a jump effect if you click repeatedly, so is there a way of firing multiple events whilst holding down the mouse button?
Code:
flvPlaybackComponentname.seek(flvPlaybackComponentname.playheadTime + fastForwardSeekAmount);
to achieve the skip through the video, but this only happens as I said with multiple clicks.
