Professional :: Live Preview Not Displaying If Added To Existing Component?
Feb 22, 2010
I've created a swf for a component live preview. The live preview appears to work ok when creating a new component, and setting the live preview in the component definition panel.
When I update an existing component definition (in a separate component library FLA) the live preview does not work. The strange thing is if I copy the entire (component FLA) library and paste it into a new FLA it works fine (although in doing so I receive a whole bunch of errors in the output window saying - Plugin tool script error in method ik_isIKContainer).
There seems to be very little information on developing a custom component with live preview.So far i've created a swf whose application class extends UIComponent.I've also created a custom component.Then I've added the Live Preview field in the custom component's Component Definition.What I would like to do now is reposition elements within the preview swf when the user resizes the component.
To do this i need to know two things - 1 what event to listen for when the user resizes the component, and 2 the current dimensions of the resized component.
1. My only success was that ComponentEvent.SHOW seems to dispatch when the user resizes the component. (i had no luck with any of the RESIZE events - Event.RESIZE etc)
2. However the width/height properties don't seem to change on resize, they stay at the original dimensions of the component.
I've created a class in AS3 which I've linked to a component in Flash CS5 and exported as a SWC. That SWC is then loaded into my main flash file and used inside some movieclips. The issue is that I want some code in the class to be used when using the component in Flash CS5 (for previewing purposes) and some code to only be used when running the main swf. Is there any way to detect when the class is being used in Flash CS5 vs being used when running the swf?
I'm having a problem with component live previews. If I just create a movie clip and set the live preview, all instances of the clip i put on stage update separatly from each other (their live preview that is). As soon as I change the clip to a component (export .swc or compiled clip) all the instances update together. eg if i set the component parameter 'title' - all titles of the all the instances on the stage will change. This didn't happen when it was just a movieclip - all instances changed separatly as i set them.
I have a project with a bunch of movie clips. Each movie clip has it's own animation. The problem is I can't see the movie clips on the stage, I have to test the movie. Live preview is checked, but greyed out. Is there anyway to live preview working on main stage?
I don't really use Flash, but was just trying to put up a little video demo online.
Just dragged the video onto the canvas, published it as an .swf, but when I upload it all and visit the web page, the video clip / swf isn't displaying.
I am working with an AS2 application that was put together a while back. The app is used to publish a live video stream to FMS. I am using the Camera class to connect to a local camera (Camera.get()) and to setup the encoding specs for the stream that is to be published to FMS. To preview the camera signal, I am using Video.attachVideo() to attach that camera output to a Video instance on the stage. This is all working greta for me. But here's the thing. The video stream that is being pumped to the Video instance is the direct signal from the camera. Nice and clean. I seem to remember that there is a way to view the video signal with the encoding settings applied to it. It's just one little line of code, if I remember correctly. However, I can't seem to find the code that will do that.
Can anyone quickly share the code that will allow me to preview the encoded video stream?
I want to develop custom components (that show up in the Components panel) which a Flash designer can drag onto the stage and use the Component Inspector to customize it to their liking (inspectable parameters, I believe they are called). I'd also ideally like to implement a Live Preview so they can see their adjustments live on the design stage.
Does anyone know a good resource for learning the correct way to do this? I've found one that used to work in CS3 but now that I am on CS5 it isn't happening for me: [URL]. There's also the "official" Adobe blog post, I think the previously mentioned article gives it an appropriate shout-out for being "long and cumbersome". It seems that this should be a pretty popular technique.
Say I got a live event called game in "C:FMSHOMEapplicationslivepkgrevents\_definst_game" and push a MBR stream for awhile and see the ".stream" files being created, everything works good.
However whenever I stop the stream, delete the contents and try to republish another stream to this event name never recreates the '.stream' files or stream directories.
1. Delete the files "C:FMSHOMEapplicationslivepkgrevents\_definst_gameMsadsaasa.str eam","C:FMSHOMEapplicationslivepkgrevents\_definst_gameMsadsaasa .stream".
2. Delete all the stream directories - "C:FMSHOMEapplicationslivepkgrstreams\_definst_game1", "C:FMSHOMEapplicationslivepkgrstreams\_definst_game2".
Is this normal behavior or is there a default waiting peroid before reusing an event name? Should I only publish to a liveevent name once?
public class ItemView extends MovieClip { private var _title:TextField; private var _extra:MovieClip;
[Code]....
When I create an instance of ItemView and add it to the stage, "Title" displays but the blue square does not. However, if I make the graphics calls on this instead of _extra, I do see the blue square. This tells me that _extra itself is not displaying properly, but I can't figure out why. Is there some special procedure for adding one MovieClip to another?
I'm adding a series of objects dynamically to my flash movie from xml but they won't appear when I run the movie. I have nearly identical code adding objects in a different swf that works just fine. I have tested this 8 ways from Sunday including ensuring that they were added to the container which is a child of the main MovieClip (tested the display list), that they were added to stage (had a listener for ADDED_TO_STAGE) and that their position was correct (displayed x,y values and compared them to mouseX & mouseY values). They are in the correct place in the display list. Still there are no objects. The class is linked correctly, I have movie clips in the library.[code]
I have FLV video component waiting for the user to push play. However, I want a thumbnails that I can stick in there because it is just black. How does this work with the FLV playback component? I can't find anything about this.
i am trying to get a preview image to appear when using the flvplayback component. it does not show up within the flash player or when i test on a server. i was able to use the component inspector to find the image i wanted and export and save it. i saved the png file in the same directory where my flv is located. here is my AS:
Code: Select allimport fl.video.FLVPlayback; var flv_video_mc:FLVPlayback = new FLVPlayback(); flv_video_mc.source = "flv/video.flv"; flv_video_mc.preview = "flv/video_preview.png";
I want to calculate how much years, months, days, hours, minutes and seconds I live from my date of birth and display this in flash (like live tracking). How can I do that?
Does anyone know what criterea Flash uses for discovering the Live Preview class for a Component? Background We are attempting to automate the creation of a SWC that contains a component to be used from Flash. We are able to make it visible to flash by modifying the manifest.xml and wiring up the component definitions. However, the component cannot be dragged onto the stage (or library), presumably because it has no form of LivePreview. To give better clarification of where we are coming from, we've noticed the following in SWCs exported from Flash (using swfdump):
fl.livepreview.LivePreviewParent contains the same mod attribute as the visual component in the manifest.xml file fl.livepreview.LivePreviewParent is exported as a symbol The short-named component (ie. no package, referenced in the components definition in the manifest.xml) is exported as a symbol However, I can see no other differences between that and the SWC from Flex. We can obviously use JSFL to perform the task, but we'd rather not install Flash on the build server.
I've been customizing the flvplayback component and have run into a problem. So far I have successfully created a custom skin for the flvplayback component, with a play overlay button,which loads the FLV dynamically from flashvars.I am now trying to load in a static image which appears until the video is played.I've been looking around the internet and in the Adobe forums, but haven't found what I'm looking for.I thought perhaps the Preview min the AS3 flvplayback component would help, but this won't work apparently.
I was thinking myPlayer.source = "image.jpg"; but then how can I change what the source is once someone clicks on the video? I also found fl.video.VideoEvent, but I'm not sure how I can use this to set the image as the source, until someone presses the play button, or until the video is playing (note that I am using an overlay play button which shows up whenever the movie is paused, so once the video starts playing, I would not want the static preview image to come up again...just until someone clicks the any play button).
I have found something good here. [URL]..The mouseover effect on the list item is good. Any ideas to make this look.. I can infer that this is happening on mouseover of the Image Component. I think this is similar to google image search preview of images. If anyone have come across a component similar to this kindly share it to me and to all.
I created a flex component that hosts several built in (mx) components such as a listbox and combo box. My component relies on external data, and I need to expose events such as ComboBox.enter and List.click to get certain pieces of data.I was wondering if there is any easy way to do this without having to create my own custom event handlers. I'm simply trying to expose these events with different names so that when my component is used, I can do things such as:
I'm looking to simply append the following text to an existing spark.components.TextArea's text flow: <b>something</b>: hello world
I have attempted to do this using the following code, but nothing happens: this.textarea.textFlow.addChild(TextConverter.importToFlow( "<b>something</b>: hello world", TextConverter.TEXT_FIELD_HTML_FORMAT));
How can I accomplish this? I know in the old mx.controls.TextArea component, I could simply do: this.textarea.htmlText += "<b>something</b>: hello world"; How can I do this with the new TLF/FTE API expressed in the spark.components.TextArea component?
I am overlooking something, but why won't my FLVPlayback component, which is in my library, be added to the display list? When the code executes, there is now FLV component on stage.[code]...
I'm having some trouble with getURL (I think). It works fine when I preview with Flash's html preview but it's not working on my server. It's pretty simple. [URL].selected1 is a user-defined variable pointing to a page: ie, when the user selects variable page1 the page to be opened is [URL]. Like I said, it works with Flash's preview, but not on my server(no 404 or any response). Does there seem to be a problem with my code or might I be overlooking a server error? Here's my code:
I have a component A in my flex project where people can vote for their favourite artist. Someone "likes" an artist, it get's updated in my database. There is also a component B that shows a chart of the most liked artists. I call the data from the database on creationcomplete in Flex. The problem is that when a person first votes on an artist, it will not be visible in the datagrid untill the user reloads the main page (?) or reopens the entire application. So i was wondering how i can update the datagrid everytime someone adds a vote to my database. I'm now using an update button, but that's not very user friendly of course.
in windows live messenges the status setting component tht is an icon, label and a dropdown arrow. on rollover it gives u border around the component, how to implement the same in air application using flex. i got this link. [URL] but how to implement it in flex?
I have a 700px heigh movie, which makes the browser scrollbar appear on most resolutions. If I focus on the html part the mouse wheel works fine; however if I bring the focus to the flash movie (simply clicking on it) it doesn't work anymore! This started to happen when I added the numericStepper component to the stage even if the focus is not on it.
else I'm going to get my hears pulled by the flash-accessibility-sucks people.
I've searched high and low and haven't been able to figure out a way to set a preview image for video I'm loading in using the mediaPlayback component. Using Flash CS4, AS2.
This is probably a very easy question but i dont really have an answer for it... what i want to do is show one full-size element after another. Currently im using a VBox with 2 elements inside, but it just divides itself into half and adds sliders onto both elements. What i want is to show both elements in their full size and for the VBox to add a slider if necessary.
I have a swf with two layer which both show when playing the animation in the flash timeline editor environment but when played in the preview or published one of the layers isn't shown.
I have an FLA file and movie and wish to upload the movie file to a server. However, when I click File | Preview in HTML the HTML file fails to generate (I see only the background colour of my FLA in my browser).
Using Flash cs5I have a simple swfnothing on the stage except a video (flv) playback component.I dont want it to autostart which i see the paremeter for and have set that to uncheckedBut I would like pick a place in the video to be the thumbnail image for the video that people see instead of just a black box. I dont see how to do that.Is there any way to have them see a thumbnail image in the video player instead of a black box when i dont want the video to autoplay?
