I need to programmatically add a set of controls with some amount of pixels between them. I can't seem to find how to do this in the Flex docs.
View 4 RepliesI have a spark skinnable component which contains a datagroup with images. The datagroup is scrolled by hovering the mouse over it. Everything works fine except one thing: after I change the datagroup provider, I need to scroll down automatically. The problem is the images are not loaded immediately after I set the provider so (contentHeight - height) does not yet represent the actual maximum scrolling position. Is there an easy way of telling the datagroup to scroll down as its content loads? Because the workaround seems to be not so straightforward. This is the code for scrolling(thumbnailStrip is my datagroup):

I have a small tween animation, which i copied to AS3 code using the automatic feature in Flash CS3. the animation basically shifts a certain movie clip horizontally (only X axis) a few pixels. the line of cose which is responsible for this is: <Keyframe index="4" x="500"/> i wanted to make this animation slightly smarter. i want to have that code take the movie clip to a specific X coordinate no matter where it is on stage at the moment the animation is triggered.
for that i wrote the following code: var n:Number = work_btn.x - (-172.4); whereas work_btn is the instance name of the movie clip controlled by the code and -172.4 is the specific X coordinate i want the movie clip to go to when the animation is triggered. i figured that way, n stores the pixel distance between the current location of my movie clip and its final destination. now is there any way i can tell the code to move the movie clip by n amount of pixels?
[Code]....
so instead of the pixels being dissolved, the pixels being added? :
ActionScript Code:
var Anim:TransitionManager = new TransitionManager(blackbox);
Anim.startTransition({type:PixelDissolve, direction:Transition.OUT, duration:1, easing:None.easeOut, xSections:35, ySections:35});
basically what i would like is the end point to be the start point and the start point the end point.
I have a swf file that loads into my main movie, and within that swf there is a masked image that i would like to scale using zoom in and out buttons and also by using a slider bar.However i cant find any tutorials that will allow me to combine the two.I have used the following code for the buttons. Which seems to work ok but i would like it to be a little smoother. (using speed or some sort of easing??)
ActionScript Code:
zoomPlus.onRelease = function(zoomIn) {
if (test_shirt.shirt._xscale == 400 && test_shirt.shirt._yscale == 400) {[code]....
but for this code it keeps shrinking my initial object down to 10 pixels by 10 pixels..
I have a movie clip called column1_mc. when I click a button I need to move the movie clip in incremental moves consisting of 30 pixels.
column1_mc._y = 30;
Does not work because that is giving a _y coordinate.For example.I need to make the movie clip jump to _y 300 but make 10x30 pixel incremental jumps. Moving 10 times 30 pixel jumps.
I have been having a serious issue with custom video where flash is saying that the amount of the video so far played is MORE than the amount that it has downloaded, which is clearly impossible. This results in various problems, such as the playhead (scrubber) moving past the end of the loader bar. I posted a simple demo that displays the amount loaded and the amount played in text fields. You can see it at: [URL][Code]...
View 5 RepliesSo I have been having a serious issue with custom video where flash is saying that the amount of the video so far played is MORE than the amount that it has downloaded, which is clearly impossible. This results in various problems, such as the playhead (scrubber) moving past the end of the loader bar.I posted a simple demo that displays the amount loaded and the amount played in text fields. You can see it at: URL...[code]I encoded the video at a high rate so that it would download slowly. It may not playback smoothly, which I am not concerned about. What I am concerned about is the numbers below the video what are derived from ns.bytesLoaded and ns.time. If you watch it for a bit, the amount played should exceed the amount loaded.
I double checked the video duration and the bytestotal that flash is reporting and they are correct. I don't know of any way to check the accuracy of bytesloaded.If your internet connection is super fast, you may not see the issue - it only occurs when it is playing back faster than it is downloading - if this is the case, you may need to throttle your speed down, or start downloading a large file while you are watching this demo in order to see the issue.But this is a serious issue and means that building custom video interfaces with loadbars and playheads is impossible!

View 3 RepliesI'm using a dateField component (with editable = true) as an itemEditor in a dataGrid. Interestingly, when editing the textInput part of the dateField it doesn't seem to react to an ESC keydown as I would expect, i.e. reload old dateField value and give up focus. This seems to be standard for most other components, but not for as most other components do.
How would you go about implementing such behavior? I can listen to keydown == escape on the TextInput portion, but just realized that I don't know how to tell dateField to give up focus and politely close - in fact I'm not even sure that's the right strategy (maybe I should work at the DataGrid level?

View 1 RepliesI am using ColorMatixFilter on an Image in Flex. I am really close to getting want I need out of the filter.Basically any PNG file the user uploads I want all pixels that are not transparent to be colored black. I have a function that sets the "brightness" already so I just through a really large negative number at it like -1000 and it does the job but the problem is any pixels that have any alpha to them, say 0.9 or below all end up being white when I encode my PNG file on the server later.
[Code]...
I would like all pixels to be solid black unless the pixel is completely transparent and not sure how to tweak the values to get that out of it.
I am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:
private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....
I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?
override protected function createChildren( ): void
{
super.createChildren( );[code]............
Here is my tree tag:
<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />
I need to load several images as Bitmap or BitmapData objects. The images are hosted outside the Flex project, and they're referenced by an external configuration file, so I can't embed them. Because the images won't be displayed directly to the user (they're being added to a PDF that is generated for download), creating a grouping of Image objects, attaching them to the application, and waiting for their LoadComplete handler to fire seems inefficient.
What is the best way to load these images into an application? Programatically load images in it?

View 2 RepliesI would like to know the correct way to close an AIR application programmatically. In my Spark WindowedApplication I have:this.addEventListener( Event.CLOSING, shutdownApp );and of course an implementation of the shutdownApp method (which basically tidies up temporary files).his works fine for the top-right close button of the window. However I also have functionality which needs to shutdown the application. Within the code I have called:NativeApplication.nativeApplication.exit();However this doesn't trigger the Event.CLOSING method, and so my temporary files are not cleared up. Should I not be calling nativeApplication.exit ? If so, what should I call instead? I'd rather not have to call my shutdownApp method before the NativeApplication.exit() as this doesn't feel quite so elegant.

I have various components that are skinned through a programmatic skin. The skin class references a singleton class that holds various colors to be applied to different aspects of the component. The singleton class has default colors set to variations of black/grey etc. I'm loading in custom colors from an XML file that are then loaded into the singleton. I'm applying the custom skin through a css stylesheet that is included in the main Application mxml.
The problem is that when the swf initially loads, the components that are drawn on screen are black and don't reflect the changes in color loaded from the XML file. I have some dropdown windows that show on button clicks and those dropdowns do reflect the correct colors from the XML file. Therefore, the system is working correctly, but the initial drawing of components obviously happens before the XML is loaded and applied to the singleton.
My question is, is there a way to apply a skin to an element programmatically by calling the constructor?
I have this in my css file:
.PanControlsBackground {
borderSkin:ClassReference('skins.buttons.PanControlsBackground');
}
[Code]....
or something to that effect? This way, I can remove the loading of the skins in the css file and control when they are instantiated to ensure that the correct colors are applied before displaying the various components.
In Flex you can stream microphone audio to an FMS/Red5 server using NetStream.attachAudio, which requires a Microphone object. Is it possible to stream audio through the NetStream from somewhere other than a Microphone? For example, from a file/embedded resource?
The reason I'm asking is that I'd like to be able to run automated tests that don't require using an actual microphone.
I have a question I came up with 3 days ago about how to do the blue underlining of a datagrid row programmatically. I thought to have found the solution, with just adding the column and row Indexes to the datagrids editedItemPosition Property.It turned out, that this is just practical if you want to be able to edit the grids row right away. But what if I just want to underline it with the blue color?Additionally how to detect that a list based Item got this kind of selection? es there a event to detect that? whats the name of this kind of selection?

I created an application as part of an ASP.NET site. I would like to receive error notifications in my inbox whenever something goes wrong with that flash application.As I do not have control over our mail server (which has a different domain name), I cannot establish a cross domain policy allowing me to send error emails to my inbox.Instead, thought I'd send a request to an ASP.NET handler that sends an email on behalf of the flash app.Now the problem: the error report should include a screenshot of the flash application at the time the error occurred. The FileReference class however only allows file uploads with user interaction (browse dialog) and cannot be used programmatically to send the screenshot to my ASP.NET handler. The plain old POST back only allows files up to ~200K.

How to programmatically enlarge a flex 3 button's hitArea. Is there some function that I can override? There is no function in the button class called hitArea. What I have done is, I have created a programmaticskin for a button. The form of the skin consists out four arrows. In between the arrows there is nothing (meaning transparent). Because of the way the skin is shaped, it's difficult to click on the button. The skin has alter the buttons hitArea.
