I'm currently working on a project, and in it I'm extending a ComboBox like so:
Code:
package test.dropdowns {
import fl.controls.ComboBox;
public class Propertytypes extends ComboBox {
[Code]....
I've stripped the class down to the basics to make sure its all working, but I'm getting the following error:
1017: The definition of base class ComboBox was not found.
I'd like to adjust the width of the default ScrollBar that appears inside of a Flash ComboBox. From my research on various forums, it seems like the best approach would be to subclass fl.controls.ScrollBar, which I've tried doing here:
package helpers {
import fl.controls.ScrollBar;
public class CustomScroller extends fl.controls.ScrollBar {
[Code].....
Then, in my library, I've taken the "ScrollBar" movie clip that appears upon initial creation of a ComboBox and changed the base class to "helpers.CustomScroller". I've got three ComboBox instances on the stage; however, none of them are showing anything but the default width, nor am I seeing the output from the trace() statement in my constructor.
I don't how to describe the situation in short, so I am going to describe it in details.
I have created a class, extended from MovieClip. It looks like this:
// Libraries are imported
public class WindowObject extends MovieClip {
public function WindowObject():void {
dragArea_mc.addEventListener(...);
[Code]...
When I clicked on the errors, they redirected me to the WindowObject class.If I don't create new classes, but just write the additional functions on the MovieClip directly, and set back the base class to be WindowObject, it works fine again.
Basically the issue I am having is related to the TextField class. I was hoping to create a custom textField class which would allow me to specify the x and y positions of the textField upon creating it.
However in trying I received numerous errors. Below is my code.

I'm using Flash CS3 and want to create a custom ComboBox. I've followed the steps outlined in "Editing component skins in a new document" (http:/[url]...), but every time I get to the step where I drag the ComboBox Assets folder from the HaloTheme.fla library into my library, if I test movie at that point my combobox has become an unclickable white rectangle with no label, button or anything.
View 2 RepliesI'm trying to set a specific list item in a mx combobox to have a custom item renderer, the problem is that I cannot do this via mxml, it needs to be done via actionscript at a later stage, eg: combobox gets created, combobox gets populated, user does other tasks, combobox needs to set one or more items in the combobox to have icons (via item renderer)..
I can do this via the onChange event, but it only applies the icon when the combobox is opened and there is a slight delay so you can see the icon being added.
How can I validate there's a selected item in a ComboBox before saving? If there's no selected item, how can I set focus on the ComboBox?

Both of my ComboBoxes has the same identifier.I could not change the identifier through the properties tab because it is greyed out.
In my Flex 4.6 web application I use mainly spark components, but there is also an mx-component - a PopUpButton extended by me (the source code is below).Users report problems with that button, but I can't reproduce any - since weeks.
I've tried replacing mx:Menu attached to it by a s:List but it hasn't changed anything. I suspect there is a "null pointer exception" or some other failure, that I don't hit when testing myself...
My question is: why does Flash Builder reports warning about my custom button as if its methods would be private or not present?

I have a flash file, which's dimensions are 500 px by 500 px. That's how I want it. However, sometimes something happens in the flash movie, causing a movieclip to extend outside the dimensions (which I need it to be seen by the user). Im putting this swf into an html file. I definately know there is a way where those out-of-bound movieclips can appear (inside a browser), overlapping other html elements, but I forgot how. Well, setting the wmode parameter to transparent will cause the movie to become transparent, revealing whatever's underneath, but this doesn't solve my problem. I don't want my movieclips to look "cut" when they happen to pass across my bounds. Probably the DIV tag is related here. I know that the cheapest way to solve this is by setting the movie dimension to something like 999 by 999. But I dont want to do that!
View 3 RepliesI'd really like to be able to make Flash's array access syntax 'wrap' over the array's bounds.
Lengthy explanation -
var array:Array = ['a','b','c','d','e','f'];
To keep things simple, the first index is 0, and its value is the first letter, 'a'. To get that value, we'd do this -
array[0]; // returns 'a'
As long as the index you're using to access the array is between 0 and array.length (6 in our example,) everything works fine - but if you use an index outside of those bounds, you're shut down.
array[-3];
array[9]; // both return 'undefined'
Sometimes that's a good thing - sometimes you expect that to happen, and you're fine with it. Other times, you find yourself wishing (or at least I find myself wishing) that it'd behave a bit more like this -
array[-3];
array[9]; // both return 'd'
(e.g. a photo gallery that jumps back to the beginning when you click 'next' on the last photo)There's a little chunk of code I use over and over for this sort of thing, but it's always to alter the index before passing it into the array:
var index = -3;
while(index < 0){index += array.length}
array[index % array.length]; // returns 'd'
... and that's fine, but what I really want to do is extend the Array object itself so that it'll automatically 'wrap' index values that go out of bounds.TL;DR - Is index-wrapping possible by extending Flash AS3's Array object?
I made a custom event, but was getting this runtime error: TypeError: Error #1034: Type Coercion failed: cannot convert flash.events::Event@1498f491 to com.esidegallery.net.BatchLoaderEvent. and eventually found what I thought was the the answer here - [URL] I made the necessary changes, but I'm still getting the same error! It's just a batch loader that dispatches a custom event for every item that loads, with its LoaderInfo object attached. Here's the event code:

I am creating an object pool to cache some recyclable objects in memory at the outset of my application in order to avoid (as much as possible) the performance issues caused by GC running; if possible I'd like to minimize the memory my object pool reserves, so I'm attempting to pool generic forms of the objects (with no methods) and then casting the generic variants to more specific and complex object types which extend the generic form when I actually want them on the stage.
The trouble is that to do this requires the generic variant class to import/extend MovieClip (because the more complicated objects are themselves MovieClips and make use of DisplayObject methods)-- does simply importing and/or extending a class add to the memory an object takes up when instantiated even if it never uses methods from the inherited class? It makes sense that it would, and some light profiling seems to suggest that it does, but I'm not 100% certain. About how large should an 'empty' MovieClip instance be in bytes?
I have a coin MovieClip which revolves around different orbits in my puzzle game.

Is there a way to set a combobox component to multiline in Flash CS4 using actionscript 3 ?
View 1 RepliesI have a Flash CS4 movie that uses a standard Flash combobox. This works fine, as long as I don't use the resulting SWF embedded on a HTML page. When I do embed it, the combobox doesn't show up, doesn't dispatch mouse events, it's just as if it doesn't exist. However, if I switch to fullscreen, the combobox appears and functions normally, even if I switch back from fullscreen.
View 1 RepliesI know this is a no-brainer for people who happen to know the secret to passing variables from a combobox to PHP. I have wasted all day and I give up.
I have a working, secure Flash-based contact form which sends to a PHP file which then emails the information to the chosen email address.
I want someone to add a combobox to my existing code without altering/deleting anything else. That is all I want. I want to be able to compare before and after and see exactly how you added the combobox and got it to work. I do not want to see completely different code and for you to say, "Well, this is how I would do the email form and it works better." The form I have works great and is secure. I just don't know how to add a friggin' combobox.
I have an asset management system which loads a bunch of external swfs, and when requested distributes copies of those swfs to other parts of an app (it creates instances of the classes to do this).Anyway, when I use these loaded swfs somewhere and then remove them Flash does its trick of leaving the sounds running (as they are triggered by timers).If they were Loader class items I could use .unloadAndStop() to shut them up and get them garbage collected, but they aren't of course.I thought I might be able to extend the Loader class and set the .content my self - which I have done by overiding the content getter in Loader. I was hoping I could then use unloadAndStop on that class but nothing happens. I've tried casting my fake Loader to a Loader as well and no joy.

UPDATE:I've overwritten the configUI method in a ComboBox subclass, but the measurements are correct all the time. Why does the container height change to 100 ?
I'm trying to use a ComboBox control in an ActionScript 3.0 Project I've been tasked with making modifications to. I know I need to do import fl.controls.ComboBox; Now, the problem is that if I do this within the (unfamiliar) environment of FlashDevelop, I get an error. My understanding is that adding a control is a matter of feeing FlashDevelop the correct classpath, which I think I've done. Some other websites seem to indicate that if I add the control to my library this problem goes away because the act of putting it in the library links the required resources. So, how can I do the equivalent of adding to an .FLA library within FlashDevelop?
View 1 RepliesIs there a way using CSS, to set a mx.controls.ComboBox's background color. This would be the background color of each row when the ComboBox is clicked (expanded). I've tried backgroundColor, fillColors and backgroundGradientColors without success.
My ComboBox is contained within a FormItem. I've also tried setting FormItem's backgroundColor, fillColors and backgroundGradientColors. It's not clear to me where ComboBox obtains or inherits its list cell background color from.
I'm using the cs3 combobox control. I want the prompt "Select a City"to persist, but it disappears as soon as you select an item in the list. Does anyone know how to fix this?

I'm trying to learn AS3 the hard way (i.e. just barrelling on into it), and I'm a bit stuck on this form that I'm putting together. Aside from the normal headaches associated with form building in Flash, I've got a series of conditional contents that I need to work out.Basically, it's a no-brains-required error reporting form, and it's covering three sites, with several buildings, and a couple of thousand computers. What I want to do is to limit the amount of selectable machines available as more fields are filled out in this form: say I chose site 1, I only want machines that are actually on site one to be available. Would it make more sense for this to be done at the server end, or is there a way of getting the combo boxes to check to see whether conditions have been met prior to displaying contents?
View 4 RepliesI'm using AS2, and trying to use AS2's packages for the first time, so I can organize my .as files properly.

View 1 Replies this cursor follow works in a single frame on the main timeline with a stop action :
// kisses start and follow cursor
addEventListener(Event.ENTER_FRAME, start_kisses);
function start_kisses(event:Event) {
staged_kiss_mc.x = stage.mouseX;
[code]....
How can this same function be called in various frames throughout the main timeline? For instance, say the above code is on frame one and the "staged_kiss_mc" is extended from frames 1 to 10. On all frames there is also a stop action (along with additional code, content, etc.)How can the function "start_kisses" be activated on each of the 10 frames in the same way it is on frame 1 ?Is it necessary to add a new Event Listener? Do new functions need to be coded for each frame, such as start_kisses1, start_kisses2, etc.? --Or can the same original function be reused?
I found this sentence while googling out for Flash help: "Add 3 frames to your timeline. Drop a TextField on your Stage & make sure it extends over all the 3 frames." I was not able to accompolish the second task of this. I added the frames, dropped a TextField on the first frame, but could not find a way to extend it over all the 3 frames.
