ActionScript 3.0 :: Convert Loader() To SimpleButton()
Jan 3, 2010
I am loading a series of images from an XML file into Loader() objects, but I am having some issues with what I want to do with those images afterwards.
I need to set the size of the images to thumbnails for a sliding chooser and since the images are various widths, I cannot use a constant. I have to get the Bitmap from the contentLoaderInfo:
//This is found within an array loop and loads for each picture in the XML file (actually, every other pic)
picLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadChooserImages);
function loadChooserImages(evt:Event):void{

Do you know why this AS3 code works:
var loader = new Loader();
loader.load(new URLRequest("http://127.0.0.1/items/boing.png")));
var o:DisplayObject = addChild(loader);
o.x = 100;
o.y = 100;
But if I cast to sprite it doesn't work? Ie the sprite appears on (0, 0) instead of (100, 100):
var loader = new Loader();
loader.load(new URLRequest("http://127.0.0.1/items/boing.png"))
var o:Sprite = Sprite(addChild(loader));
o.x = 100;
o.y = 100;
How would I properly have a sprite instead of a DisplayObject? I need some sprite's features (drag'n drop, useHandCursor...), yet I wish I could still use the very quick writing with the loader.

I've seen mention of there being some security risk with loading images and leaving them in loaders. A few articles I've run across said that you should always draw them as a bitmap when the loading is done.
Is there any truth to this? I have a few loaders I have left in my project, do I need to hand their content off to a bitmap? What is the advantage of always having a bitmap represent the loaded image?

I am writing a script in which i want to do collision detection with Bitmap. Actually i took the script from book. I am using Loader class instead of Embed tag because i am using Flash IDE CS 5. If you see the code then everything is fine except one thing. That in hitTest() method i am using Loader instead of Bitmap. So it gives me error that parameter type should be Bitmap. Now my question is how can i convert Loader object to Bitmap so i can use it in my hitTest() method. Here is my code

I'm trying to use addEventListener with a SimpleButton object. In an earlier version of my movie, I had identical addEventListener code on a button from the library, and it worked great. But I had to switch to creating the button in AS3 instead, and now the code won't execute. [cpode]...

I have the images that I want to use for the button in the library, using simpleButton(), how do I link the parameters of that function to the library resources?I also have a button already made, would it be easier just to create an instance of that in the ActionScript? If so how would I do that?
Edit:Even when I try this, I get errors:
Code:
var createNew:SimpleButton = new SimpleButton();
createNew.upState = newoff;
createNew.overState = newon;
createNew.downState = newon;
addChild(createNew);

I have a virtual keyboard on screen, with SimpleButtons for each of the keyboard keys. In addition to using the on-screen keyboard, I want to allow for physical keyboard input as well.
Everything works, but I am looking for a way to trigger the rollover/down/up animation of the SimpleButton if the user uses the keyboard. Is this possible? I'm already capturing the keystroke info and matching it against the SimpleButton, but I don't know how to get the button to play.

I am working in Flash (not Flex) with Actionscript 3. I have an instance of the class SimpleButton. I have a TextField that I don't want to lose focus when the user clicks my SimpleButton. It is my understanding that both Actionscript 2 as well as the Flex class 'Button' both have a settable/gettable property called "focusEnabled". I can't seem to find an equivalent for Flash Actionscript 3's SimpleButton. I did find a link to an IFocusManager and IFocusManagerComponent

I'm working on a small project in AS3, and I need to make some interface buttons. I had them as separate classes at first, but then realized that it was probably overkill, and on top of that, figured out a way to simplify the event calls by making them buttons and assigning the event dispatches to their parent.
I tried remaking them using the SimpleButton class, but I can't figure out how to give the buttons any sort of design. Every tutorial on the web uses SimpleButton to make only the most bare-bones Actionscript graphics by actually drawing them with the code (why anybody would want to do that is beyond me), and my attempt at assigning a library item to the upState:
_deletebutton = new SimpleButton();
_deletebutton.upState = mc_deleteButtonUp; <--- exists in my library
doesn't do anything.The Adobe docs say that the various states take DisplayObjects, which mean they take Sprites and MovieClips, so you should be able to do this. Does anyone know how?

I'm working on a Flash project using ActionScript 3.
Our interface switches between different modes by adding and removing the direct children of the main stage--we call these scenes.
The problem I've encountered is this: One of these scenes has a SimpleButton (flash.display.SimpleButton) with distinct up and over states. When I mouseover a button, it goes to the over state as expected. But if the application automatically switches to a new scene (in this case, a video finishes and the app moves on) and then the user navigates back (causing the original scene to be re-added), the button stays in the over state until I mouse back in and then out again. I'd like to be able to force that button back into its up state.
I've tried setting b.overState = b.upState, but then there's no appearance change on subsequent rollovers. I've also tried dispatching a ROLL_OUT event to the button object, but that doesn't do anything either.
other than implementing something from scratch that exposes a way to force a state change?

I just spent three hours on trying to understand basic positioning of TextFields and SimpleButtons...
I have a movieclip with a dynamic TextField and a SimpleButton inside. The TextField is NOT inside the SimpleButton (because then I can't change the text dynamically).
I want the TextField centered in the SimpleButton but when I set the Textfield.x it is displayed somewhere completely different than when I set the SimpleButton.x to the same value. Regardless of if I do i programmatically or not.

I was hoping to extend the simple button class in order to have it contain a text field that I can set with code but still have the benefits of the up/over/ states etc... (To set a textfield within a SimpleButton doesn't seem possible with SimpleButton out of the box, you cant reference anything in it).

With the GUI (Flash CS3), I made a button that included an instanced dynamic textfield. Whenever I try to access it, I get the error message 1119: Access of possibly undefined property
The line is:
big_btn.labelTxt.text = "Start";
the button is named big_btn and the textfield is name labelTxt
If I change big_btn to a MovieClip, no error and it works.
Can you imbed an instance inside a SimpleButton? If so, how? If not, what's the logic behind allowing it in a MovieClip, but not in a SimpleButton?

I have a SimpleButton that contains a different MovieClip for the Up, Over, and Down states. These MovieClips all have 10 frames and corresponding frame labels. I can use gotoAndStop on the MovieClip in the Up state, but that only works until I hover over the button. Adding stop() commands in the timeline seems to give unpredictable results. Is there a way to get a SimpleButton working with the Up and Over states with a multi-frame MovieClip?

I need to have a button that contains a text box, and have the text change. First, is there a way to access a text box directly in a SimpleButton? While I know this doesn't work, it would look something like
Code:
btn.upState.textField.text="Text"
Second, since I could not get that to work, I made a movie clip, put the button i made in it, and simply put the text box over the button. The problem this creates is that when the mouse is hovering over just the button it is in the over state. When the button moves over the text box it goes back to the up state. Why it does this and if it is possible for the button to still be in its over state when the mouse is over an object that is on top of the button itself?

I've created a button under the SimpleButton class named button1 in Flash CS4. I've set button1 so it exports to AS3. I keep getting an Error 1061 at line 3 of which I have no clue what I'm doing wrong:
Code:
1 import flash.events.MouseEvent;
2
3 button1.addEventListener(MouseEvent.MOUSE_OUT, link1);

8navigateToURL(one, "_self");
9 }

i have a simple navigation system with three buttons, each button have a text field in it. On mouse over they change color to blue. I can achieve all these without a single line of code. I simply make a button of my text field in flash, and change the color of the text in the timeline.
My problem occurs when i want to make the color to stay blue when i click on the button. Apparently you can't access the child within a button, in my case a dynamic text field. I've googled this problem and they all say that you should use a MC instead of a button. Thats exactly what i have done so far. But i'm getting tired of writing a bunch of eventlisteners and put an extra layer with an invisible button in my button mc so i can get the hand cursor (because the .buttonMode = true and useHandCursor doesn't work when there is text field inside the mc). Any way, shouldn't there be a more elegant way to solve this problem?
I've been trying to build a new base class for my button that extends SimpleButton, and from there access the embedded child object, but the problem remains.
In this example i'm trying to simply change the text of the text field inside of my new MyButton instance. But i get the same old Error #1009: Cannot access a property or method of a null object reference.

{
import...
public class Mybutton extends SimpleButton

It transpires that there was another Sprite being create and set to alpha=0 which just happend to be at the same Y position as the height of the SimpleButton. This was preventing interaction with the button.
I have a SimpleButton which I am positioning on the stage. I'm doing a variety of things with it buy when I set it's Y position it breaks/alters the hitArea.
var playUp:Bitmap = getBitmap('play_up');
var playDown:Bitmap = getBitmap('play_down');
var Y:Number = 100;

For some reason this answer really eludes me, and my googlefu fails... Is it possible to customize a seekbar component so that the handle is a simplebutton (ie up/over/down states), or would I have to write my own seekbar for this functionality?
