CoverFlow component

Dear members,
I'm looking for a CoverFlow component to put in my ios application.
Could you seggest me how can I start the development of such a component?
What about license?
Thanks in advance. Regards. L.

Coverflow Component Performance

My current project is trying to utilize Flex as the UI on small form-factor touchscreen laptops/netbooks. Performance in this case is a must, especially since the application is kicking off extremely resource intensive applications in the background. So far, with a little tweaking we've been able to keep Flash in check as far as CPU and memory consumed, but I've run into problems when trying to implement any sort of coverflow display component.
It seems that all the coverflow components I can find either use Papervision, or are based off Ely Greenfield's tutorial... That wouldn't be a problem, except both seem to spike the heck out of the CPU when they are used.
In my app I'm loading up 15 items at a time, isn't using a repeater, gets children added just once, etc. Memory doesn't seem to be too bad, but on the (5 year old) Panasonic Toughbooks I'm developing for, CPU usage jumps from an acceptable 5-10% to 60%+ even when the application is idling. If usage spiked during the animations that would be fine, but once it goes up it never comes back down.
Does anyone know if there something inherent in the faux 3D that causes this, or are there solutions out there that can still do the coverflow look without the ridiculous overhead? Ely Greenfield's DisplayShelf component seems to be the best of the bunch, but minor digging hasn't enlightened me as to why even when sitting idle the app sucks up the majority of my CPU resources. (Note that I've done a lot testing and profiling on this, it is, without a doubt, the coverflow components I've tried that kill things.)
I'd be interested to hear if anyone knows of a high performance version, and I'm just curious as to whether any of you think it is possible to fix at all, or whether I should just throw out the coverflow concept in general since it won't ever mesh with my performance needs.

If your target CPU is a 5 year old, mobile CPU, then there's not much you can do.
On a modern CPU (dual core 2.5ghz), Greenfield's example is about 10% CPU usage. I'm actually impressed you're getting 60% on those old CPU's, that's pretty darn impressive IMO.

Is it possible to resize the children of a viewstack(coverflow)

I am using a coverflow component which extends a viewstack: http://dougmccune.com/blog/2007/11/03/coverflow-flex-component/
I can add children (canvas with an image) fine by explicity setting the width and height of the canvas. Then i can align the children in the centre of the canvas.
However if i specify a different size of canvas when adding a new child all the previosuly added children become unaligned.
So is there any way to resize the children of a viewstack? Or does anyone have any other solutions?
here is my add child code:
var tmpchild:Canvas = new Canvas();
//These can't be changed without un aligning other children already present in the viewstack
tmpchild.height=170;
tmpchild.width=170;
var tmpimage:Image = new Image();
tmpimage.source=imageSource;
tmpimage.horizontalCenter=0;
tmpimage.verticalCenter=0;
tmpchild.addChild(tmpimage);
tmpchild.verticalCenter = 0;
coverflow.addChild(tmpchild);
Thanks

I don't believe so. Changing the parent container will directly effect the children of that container.

Viewstate component creation policy .

Hi ,
I am creating a cover flow component , the one very similar to the example given in tour de flex. I see some start up delay . I thought of using states to show a screen with a spinner until the coverflow component got created . Hence , I set the currentstate="normalstate" at the creationcomplete of coverflow component and showed another panel with a spinner in it have state as "loadState" which is the default state . But I see that , the creation complete event of coverflow is not called as the component is not currently visible . I tried giving itemcreationpolicy to "immediate" but it seems Flex is not creating components for all view states . It just creates components that are visible in the default load state ( which is the panel with spinner in my case ) . Is there any way to specify creation of all components for all view states ? ( I tried creationpolicy = all too , doesn't seem to work )

Hi ,
I created a sample of what I need if my question is not clear . is it possible for creationcomplete methods of both panels to be called during application startup ? currently , only the creationcomplete method of first panel gets called .

UIComponent - Remove All BitmapData

Hey,
I'm using a cool flex component developed by Ely Greenfield called DisplayShelf. The compnent is used to display images in a fashion similar to the iTunes coverflow component - http://www.quietlyscheming.com/blog/components/tutorial-displayshelf-component/. This DisplayShelf component extends UIComponent.
When I load more and more images into the DisplayShelf the performance begins to suffer, which I believe is due to the number of bitmap objects which are drawn as each image is added.
My question is:
Is there a way to completely remove all bitmap data from a UIComponent using the standard bitmapData.dispose() method or failing that is it possible to simply delete all UIComponent children from memory i.e. not to use removeAllChildren which still keeps them in memory?
Thanks
Adam

Hi Alexander,
Thanks a lot for your reply.
I've found that by setting up a small loop to remove any children from the UIComponent and then loading additional images thereafter, I can improve the performance of the component hugely. Could this be because GC is grabbing the unreferenced children once they have been removed?
In relation to your two suggestions: - Yep I've got all the related objects weak referenced as you mentioned but to be honest I was unsure about forcing GC invocation manually, partly because I really wasn't all that sure on how to do it, and because I had read some place that this was not really very good practice and could possibly cause some unwanted CPU processing issues?

Does Itunes Share Quicktime Mpeg-2 Component?

I would like Itunes being able to read some of my Mpeg2 videos (thru coverflow!), so i thought about buying quicktime mpeg2 component for that, assuming that videos played thru Quicktime, are available in Itunes then.
But i read somewhere that it isn't always right, some exceptions may appear.
So... before buying mpeg2 quicktime codec, i would need to be SURE about its compatibility for Itunes, as i don't basically need quicktime player for reading my mpeg2 videos.
Does anybody knows precisely about this?

Muxed audio formats do not export audio when QuickTime is involved.
Use MPEG Streamclip (free) as it can export the audio portion of the file.

Coverflip coverflow - files keep deleting

HI. I need help. I am trying to create a coverflow using CoverFlip (with Action Script3). I have no trouble creating the coverflow but for some reason the next day the images disapper. The path where I indicate the images should be pointing to is just gone. The Value potion on Component parametes is always empty. I have tried several times with the same result. It works the day I created it but the bnext, all I get is a grey "loading" image. Do you think it is because I am uising a trial version of Flash? Will this not happen if I purchase the item? Will someonel please help
Thanks

Do you use Time Machine? Have a read here:
http://pondini.org/OSX/DiskSpace.html
FWIW, having only 10 GB of space is inviting disaster - 10 - 15 GB is to be considered an absolute minimum which the OS needs to function properly; more is much better. The disk space will change dynamically as the system reads/writes to disk constantly, every time you do anything (look at a picture, edit it, type a letter, etc).

Problem with inputText in my custom component

Hi, I have a custom dataTable component that I'm trying to get to work. It has to be a custom component because dataTable doesn't support rowspan, colspan, multi line headers, and a rendered attribute for rows. The problem is, that when I wrap the column tag inside my row tag then the method for the inputText tag never gets called in the UPDATE_MODEL_VALUES phase.
I'm starting to think that JSF doesn't support 2 levels of tags between the inputText and dataTable. I'm hoping that someone can tell me what I have wrong with my components.
Here is the JSP snippet.
<cjsf:rptTable>
     <cjsf:data id="dataTable1" value="#{allAuthUser.tableRows}" var="myTableRow1">
          <cjsf:row>
               <cjsf:col>
                    <h:inputText id="tableTestFld" value="#{myTableRow1.testFld}" size="5" maxlength="5"/>
               </cjsf:col>
          </cjsf:row>
     </cjsf:data>
</cjsf:rptTable>Here is what it renders. It looks to me like everything renders fine. So I'm guessing that there is something in a component that is causing JSF during the life cycle to not be able to process correctly.
<table>
     <tbody>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_0:tableTestFld" name="tblmaintForm:body:dataTable1_0:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_1:tableTestFld" name="tblmaintForm:body:dataTable1_1:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_2:tableTestFld" name="tblmaintForm:body:dataTable1_2:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
     </tbody>
</table>Note: If I leave off the row tag it renders the same way except of course the <tr> and </tr> tags are missing. If I do this, then the backing method for the inputText tag is called and everything works fine. Why doesn't it work with the row tag in place?
Here are the components:
public class UIRptTable extends UIComponentBase {
     public UIRptTable() {
          setRendererType("tblmaint.rptTableRenderer");
     public String getFamily() {
          return "javax.faces.Output";
public class UIRptTableData extends HtmlDataTable {
     public UIRptTableData() {
          setRendererType("tblmaint.rptTableDataRenderer");
     public String getFamily() {
          return "javax.faces.Data";
public class UIRptTableRow extends UIOutput {
     public UIRptTableRow() {
          setRendererType("tblmaint.rptTableRowRenderer");
     public String getFamily() {
          return "javax.faces.Output";
public class UIRptTableCol extends UIColumn {
     public UIRptTableCol() {
          setRendererType("tblmaint.rptTableColRenderer");
     public String getFamily() {
          return "javax.faces.Column";
}Here is part of the faces-config file in case you need it.

Hi, Ray!
1) I was trying to put a button in the column header (for sorting) and I couldn't get that to work. That involved the >colhdr tag. I got that to work but I don't remember the fix. I'll look it up and reply back with that when I can.Dealing the first part of your trouble, you need NOT a custom component.
I have looked through the implementation of RepeaterRenderer, as you advised me, and found that the multi-header possibility is included in the implementation of dataTable control.
The code below is the part of source of repeater.jsp with only change:
<d:data_repeater>  <h:dataTable>
And it works fine.
<h:dataTable id="table"
binding="#{RepeaterBean.data}"
     rows="5"
value="#{RepeaterBean.customers}"
var="customer">
<f:facet name="header">
<h:outputText value="Customer List"/>               <!� First Header row -- >
</f:facet>
<h:column>
<%-- Visible checkbox for selection --%>
<h:selectBooleanCheckbox
id="checked"
binding="#{RepeaterBean.checked}"/>
<%-- Invisible checkbox for "created" flag --%>
<h:selectBooleanCheckbox
id="created"
binding="#{RepeaterBean.created}"
rendered="false"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Account Id"/>               <!�Second Header row -- >
</f:facet>
<h:inputText id="accountId"
binding="#{RepeaterBean.accountId}"
required="true"
size="6"
value="#{customer.accountId}">
</h:inputText>
<h:message for="accountId"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Customer Name"/>               <!�Second Header row -- >
</f:facet>
<h:inputText id="name"
required="true"
size="50"
value="#{customer.name}">
</h:inputText>
<h:message for="name"/>
</h:column>
<h:column>
<f:facet name="header">                    <!�Second Header row -- >
<h:outputText value="Symbol"/>
</f:facet>
<h:inputText id="symbol"
required="true"
size="6"
value="#{customer.symbol}">
<f:validateLength
maximum="6"
minimum="2"/>
</h:inputText>
<h:message for="symbol"/>
</h:column>
<h:column>
<f:facet name="header">                    <!�Second Header row -- >
<h:outputText value="Total Sales"/>
</f:facet>
<h:outputText id="totalSales"
value="#{customer.totalSales}">
<f:convertNumber
type="currency"/>
</h:outputText>
</h:column>
<h:column>
<f:facet name="header">                    <!�Second Header row -- >
<h:outputText value="Commands"/>
</f:facet>
<h:commandButton id="press"
action="#{RepeaterBean.press}"
immediate="true"
value="#{RepeaterBean.pressLabel}"
type="SUBMIT"/>
<h:commandLink id="click"
action="#{RepeaterBean.click}"
immediate="true">
<h:outputText
value="Click"/>
</h:commandLink>
</h:column>
</h:dataTable>
You may have a look at HTML source to prove that dataTable is already what you need:
<table id="myform:table">
<thead>
<tr><th colspan="6" scope="colgroup">Customer List</th></tr>
<tr>
<th scope="col"></th>
<th scope="col">Account Id</th>
<th scope="col">Customer Name</th>
<th scope="col">Symbol</th>
<th scope="col">Total Sales</th>
<th scope="col">Commands</th>
</tr>
</thead>
<tbody>
2.) The second trouble is still unsettled as previously. Right now I have different task at my job, and I can�t continue investigation of this problem.
But when you find smth., please let me know. I�ll be very grateful.

Hi, I have an iMac running Mavericks that I am trying to hook up an older HDTV as a second HD monitor through the minidisplay port to component 3 color RCA. HDMI is not an option with this set. I have SD working, but need to find a HD conversion set up.

Presently I have a mini display port>VGA adaptor, running to a convertor box I picked up that handles S-video out, which is working fine for SD. I also have a VGA to Component Video (5 wire RCA) adaptor cable. Connecting Component adaptor dircetly to the mini display adaptor doesn't seem to work, neither does plugging it into a VGA port on the SD convertor box. I am guessing there is another convertor box out there that will help me make the transition from mini display to Component. Even if it means having a handful of adaptors plugged in. does anyone know where to find such a wonderful and magical device?
Thanks

Your setup works fine for DV, because you used a DV deck and most likely DV footage. But now you are working with 720p HD footage (what format, BTW? HDV, dvcpro HD?). That same setup won't work for monitoring HD. Now you need an HD box or card to send out a proper HD signal. And since you have an older G5, you won't find any current solutions. You'll have to look at used capture cards that are PCIx. Or you and look at the Matrox MXO, that connects to the computer via a monitor connection. DVI.

Why do I need to declare "defaultButton" ? (In a component form part of view stack)

After doing some research and some help from FlexGuy in another thread, I realize that I need to make sure I have custom components initialized before accessing parts of the component. Just recently I was thrown for a long time when I tried to first click on a form field that was part of a component in my view stack, I'd get:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at mx.managers::FocusManager/focusInHandler()[C:\autobuild\galaga\frameworks\projects\framew ork\src\mx\managers\FocusManager.as:601]
With the debugger it's occuring in the focusInHandler method of FocusManager.as: (apparently _defaultButton is null.)
// restore the default button to be the original one
                if (defButton && defButton != _defaultButton)
                    defButton.emphasized = false;
                    defButton = _defaultButton;
                   _defaultButton.emphasized = true;
This prompted me, on a whim, to delcare a defaultButton:
<mx:Form id="empForm" defaultButton="{submitButton}">
which refers to my submit button:
<mx:Button id="submitButton" click="submitEmployee()" label="{submitLabel}"/>
My question, is why is this necessary? In some examples I don't see this declared at all, but I seem to need it? (I'm calling creationPolicy="all" to make sure my components are initialized but I still seem to have to this defaultButton declared?)

Creating a new view in a component

HI,
I am trying to create a new view in a BSP component using the wizard. But the context nodes are not getting created. Its throwing up an error - "View not copied with wizard; processing not possible".
What could be the problem ? Pls help.
Regards,
Aravind.

Hi Arvind,
Before posting error, please search for it.
Here is what i found here in 2007 forum itself.
I guess you have not enhanced your component and your view.
Without enhancing the component it is not possible to add a new context node.
Here is a very helpful, follow it and the the other link within this thread,
both are very useful in this regard.
