Is there a way to detect redraw regions or at the very least when a display object is redrawn?

I have a layered window system that produces Windows 7 Aero Glass effect in Flash.
It consists of nested display objects, with overlays as so.
Root [
    GlassWindowTop [
       RenderedEffectBackground
     BackgroundForGlassWindowTop [
         GlassWindowMiddle [
           RenderedEffectBackground
        BackgroundForGlassWindowMiddle [
             GlassWindowBottom [
                RenderedEffectBackground
             BackgroundForGlassWindowBottom (e.g. the DesktopBackground)
Windows can be raised and lowered by changing their order in the hierarchy and adding new levels.
Each glass window has a designated background (containing all lower windows) .  It draws to an off-screen Bitmap the region of the background that is under the window, and applies a blur filter, tint, and parallax effects to it, and then displays that as it's own background as RenderedEffectBackground.
The problem is that "RenderedEffectBackground" is a static rendering of the window background, so in order to update it in real time, I need to detect when it's background display object (e.g. BackgroudnForGlassWindowTop) or any nested display objects are rendered.
I could simply update all RenderedEffectBackgrounds from the bottom up each frame, but that would be inefficient.   Ideally, I could detect when a particular background changes (e.g. when a textfield cursor is flashing, or a MovieClip changes frames), and then only render from that object up.  The rendering of course always has to take place from back to front, starting with the lowest window that has changed.  If I could detect the redraw regions of the Flash Player (e.g. when a textfield cursor is flashing, or a MovieClip is playing), I could optimize this system even further by checking for layer overlaps and only rendering layers whose windows intersect the redraw regions, but obtaining that level of information would probably not be possible or logical since this this essentially needs to happen during some kind of pre render phase, which Flash may not support.  Such a pre-render phase would itself be causing new redraw regions, but as long as it is processed from the bottom up, it could work.
Is there any AS3 function of the flash player that allows my code to obtain information about the display list as far as which display objects are due to be rendered, and then intercept some kind of "onRenderComplete" event for them right before rendering takes place so that I can render the higher display objects.
I originally tried to implement this as a filter, but pixel bender shaders in AS3 don't seem to allow sampling of an underlying object that would allow for blurring (i.e. the shader can access only the current point being rendered, coordinates passed to the sampling methods are ignored (this is documented behavior).
Any ideas?

  • Is there a way to bring back link information at the bottom-left when highlighting a weblink or email address in FF29?

    I used to use the Addon Bar in previous versions of Firefox...not sure why it was removed as a lot of people use it, but I now have the extension that brings it back. However....in previous versions of Firefox, at the bottom-left, there was a place where a link or e-mail address would be displayed if I hovered over it with the mouse cursor without clicking...that function seems to be gone now...? Is there a way to bring this function back in FF29? Also, why were separators removed....it seems like a pointlessly trivial feature to eliminate...I miss them for organizing my UI! :(
    Thanks for any help or suggestions! :)

  • Is there a way to detect two keys at the same time?

    Is there a way to detect the keys if the user is holding two keys down at the same time?

    yes, but you'll have to check outside of the event loop (i.e. don't check for it in the keyPressed method).
    just use an array of keys that keeps track of which keys are currently down and which are up. you could use a boolean array but I use an int array because... Im not sure I've just done it probably because of my C background. anyway, basic setup:
    import javax.swing.*;
    import java.awt.*;
    import java.awt.event.*;
    import java.util.*;
    public class MultiKey extends JFrame {
         int keys[];
         public MultiKey() {
              super();
              keys = new int[256];
              Arrays.fill(keys,0); // 0 = key is up
              enableEvents(AWTEvent.KEY_EVENT_MASK);
              show();
         public void processKeyEvent(KeyEvent e) {
              // the 0xff below binds the key code to below 256
              int key = (e.getKeyCode()&0xff);
              if (e.getID() == KeyEvent.KEY_PRESSED) {
                   keys[key] = 1; // 1 = key is down
              else if (e.getID() == KeyEvent.KEY_RELEASED) {
                   keys[key] = 0; // 0 = key is up
         protected boolean isKeyDown(int key) {
              return (keys[key] != 0);
         protected boolean isKeyUp(int key) {
              return (keys[key] == 0);
    }so now at any time in your code you can check key state by using the isKeyUp and isKeyDown methods. this is about as close as you get to input polling in java unless you use LWJGL or something similiar ;)
    you can try out a full executable example at my site here - just open up the jar and start holding keys down :)

  • Is there a way to detect all the photos already transferred to double (or triple) in iPhoto, so do not occupy space unnecessarily? Thank you from France.

    Is there a way to detect all the photos already transferred to double (or triple) in iPhoto, so do not occupy space unnecessarily? thanks from France

    Look in you main photo library. Are there doubles or triple photos there? If so delete the extras.
    All photos are stored in the photo library. When you move a photo into an album the photo is not duplicated. The album contains a pointer back to the original photos. These pointers or aliases take up very little space.

  • Is there a way to detect motion and set markers automatically?

    My video includes walking around with the camera.  I walk, then stop and hold the camera in one area, then pan, then continue walking (and repeat). 
    While panning, there is some annoying flicker of vertical objects (beams, poles, whatever).  I can use a horizontal fast blur to fix this, but I only want the blur applied when there is panning (not when the camera is relatively still).  Doing it manually is cumbersome.
    Is there a way to detect when motion is going on (over a certain threshold)?  I would like PP to tell me when there is significant motion, and place markers in the points where it begins and ends (when motion goes over a threshold and then when it falls below the threshold).
    Thanks, experts!

    One thing you can try is to bring your footage into Prelude - it will lay out the entire clip so you can see thumbnail snapshots for the whole clip at once - that might give you a good start to see where there is a lot of motion.  Then, you can add markers very easily at all of those points - and when you send it over to Premiere, the markers will show up on your clip. 
    Not automated, but a good workflow to achieve what you are looking for.

  • Is there a way to detect if Excel is busy?

    I have a VI that is testing three products at the same time, and writing data to three different excel spreadsheets.  If more than one subvi is writing to Excel at the same time, I get an error.  Is there a way to detect if Excel is busy, and wait until it is not busy?
    metzler CLAD

    The correct answer is the one that Putnam (and others) suggested: Encapsulate all the logic to perform a single write into a VI that is used wherever you need to write to an Excel file. This structure will guarantee that the code will only be writing to Excel from one place at a time.
    If you don't want to have the different sections of the code waiting for their turn to come up, a variation on the theme would be to create a separate stanalone process that does nothing but write to Excel files. The rest of the code would pass it the data to be written using a queue. With this approach everybody seems to write at the same time, but the standalone process is actually serializing the Excel operations. This approach could even be extended to include the ability to read from files, but that is as they say, "...left as an exercise for the reader..."

  • Is there a way to reuse a region in multiple pages?

    Is there a way to reuse a region in multiple pages?
    For future maintenance, it would be easier to make changes in just one region. Maintaining multiple copies of a region is more work and eventually someone will forget to change one of the regions.
    Thank you.

    Hi wolfv
    Create your region on page 0 and then conditionally set the display of the region for specific pages in you application only.
    Under the region's "condition type" attribute select " Current page is Contained within Expression 1 (comma delimited list of pages)" and in Expression 1 put 1,2,4,6,99 etc or what ever pages you want it to appear on.
    This works especially well for tree regions.

  • Is there a way to create a fade only for the first loop?

    I have a loop (Modern Guitar Rock 04), which I've extended out so it repeats four times. I select the Fade Tool and X-Fade for drag. I then drag just in front of the loop and onto it, which creates a fade. However, this also creates fades at the beginning of the repeating loops. Is there a way to create a fade only for the first loop?

    The loop function always repeats the same region so of course the fade is also copied. So option+drag the original region to make a (non clone) copy, fade the first region and loop the second one (which you just copied).

  • RE: Is there a way to have 2 network cards on the samemachine

    Sean,
    I mean I am always connecting to the nodemgr of the 2nd environment
    successfully. Only when I run the client part of the application that I know
    is up, I get a response from the Name Server that it is actually the first
    IP address.
    I checked again. I defenitely have FORTE_NS_ADDRESS set to IP:5004, in my
    case, and not the hostname. I don't have FORTE_LOCATIONS set any where. the
    NS_ADDRESS for env2 has only 1 IP address associated with it. My Forte
    Control Panel on the client, and hence the NS address has only one entry.
    I tried going into escript like you said, and the name service still thinks
    it is IP1.

    Subject: RE: Is there a way to have 2 network cards on the same
    machine
    Hmmmm? That is a little odd! Let me rehash what I think you are saying.
    You now have two environments each with their own name service with
    FORTE_NS_ADDRESS set to a different IP:Port combination. For example you
    are doing the steps:
    FORTE_NS_ADDRESS=255.255.255.1:5000
    start the nodemgr for env 1
    FORTE_NS_ADDRESS=255.255.255.2:5000
    start the nodemgr for env 2
    Now when you start a client you are always getting the address for env 1
    back from the nodemgr. I assume you actually mean the name service? Or, do
    you mean you are always connecting to the nodemgr & name service for env
    1?
    If the first scenario is the case and you are connecting to the nodemgr
    for
    env 2 but getting back IP's for services listening on the card for env 1 I
    would ask you what you are setting the FORTE_LOCATIONS value to before you
    start each service. If you are not setting it or are using the host name
    it
    will register using the IP for the primary network card associated with
    the
    machine name and I am again assuming that this is env 1. You need to set
    the FORTE_LOCATIONS variable to 255.255.255.2:0 (based on the steps above)
    before starting your services.
    If the second scenario is the case I would have you check what the
    FORTE_NS_ADDRESS is set to before you start up the client. Once again it
    must be the IP:Port combination not host:port combination if you want to
    get
    anything other than the primary card.
    I would also suggest that you do the following. After everything is up
    and
    running execute the following commands:
    escript -fns "ip for env1":port
    findsub nameservice
    showpart
    What you should see is everything currently registered under the name
    service. It will have the name and any "locations" (IP and port) that it
    is
    registered as listening on. I would look for the nodemgr and see where it
    has advertised itself. I would then look for any services you expect to
    be
    registered there and also verify where the have advertised themselves. If
    there are multiple locations listed for any one service, the client will
    use
    the first one in the list.
    Do the same for env 2.

    Hello Venkat,
    I probably should have mentioned this before. Your are correct. Forteis
    doing a host lookup if you are providing a name for examplemachine1:5000.
    You can bypass the host lookup by using the actual ip dot addressinstead
    for example 255.255.255.255:5000. This way you are taking the name
    service
    out od the picture and Forte will use the address provided.

    My requirement is that my second card serves as best case performance
    testing piece. This eliminates the network completely. We went one step
    ahead and created a new enviromnent for the second card. Whatever I do,
    the
    nodemgr is returning back the IP address of the first card, even thoughmy
    FORTE_NS_ADDRESS does not have the first card in the picture any where.
    I think Forte is doing a host look up and returning the first IP address
    it
    finds, as opposed to returning the IP address specified in theenvironment
    variable FORTE_NS_ADDRESS. Is there a way to trick it?

    Subject: RE: Is there a way to have 2 network cards on the same
    machine
    OK, you ran into one of the issues. That is, if both addresses areknown
    to
    the client that is trying to contact the partition it will always usethe
    first address in FORTE_LOCATIONS. This is because FORTE_LOCATIONS was
    designed more as a failover mechanism. So it will always try the
    first
    address in the list and if it succeeds, there is no reason to move onto
    the
    second.
    Now, the second issue is that there is currently a problem with theclient
    failover to the secondary address in FORTE_LOCATIONS. If the firstentry
    fails it is supposed to retry on the second entry. Instead, it
    retries
    the
    first entry again. I know that Forte knows about this but I do nothave
    a
    bug number on it.
    With that said, lets look at a possible solution for you. If the real
    objective here is to have a back up network card available for fail
    over
    on
    the same machine, or use one card to advertise outside your firewalland
    one
    to use inside, then you will have to contact Forte to determine whenthe
    failover problem will be fixed. But, if the objective is to loadbalance
    across the network cards you could have the environment manager listenon
    both ports and then alternate your server partitions across both
    cards.
    For
    example:
    set FORTE_NS_ADDRESS=card1:5000;card2:5000 and then start up the
    environment
    manager
    set FORTE_LOCATIONS=card1:0 (the 0 in the port causes the OS to pick a
    port)
    and start partition one
    set FORTE_LOCATIONS=card2:0 and start partition two
    and so on....
    In this scenario the environment manager will be listening on bothcards
    but
    each server will be listening on only one of the two cards. So if a
    request
    comes in for partition1 it will go through card one and if it is for
    partition two it will go through card two. You could assign your
    partitions
    to cards based on expected load.
    Well, I am done. I hope this helps!

    Sean,
    Thanks for your reply. I tried the approach. I was not very specificin
    my
    question. I do need the ability for server applications to listen and
    server
    on both the network cards.
    I was succesfully able to make the nodemgr listen on both the cardsand
    actually serve requests coming in from both the cards. But, followingyour
    advise, I took a cautious step with FORTE_LOCATIONS. Here is what I
    noticed.
    I have an application that has 6 partitions in total. I used
    FORTE_LOCATION
    to make it listen on 1. Both the cards. 2. Swapped the IP addresses
    for
    both
    cards for this application. 3. One card that I want it to listen on. I
    tried
    all approaches by exporting the locations variable for just this
    application. The nodemgr recieves a request from this pc connected onthe
    second card to talk to one of the partitions. The node mgr responds
    with
    a
    proxy - with the ip address and socket number of the first card. The
    FORTE_NS_ADDRESS variable looks like this:
    IP1:5002;IP2:5002.
    Is it possible atall to resolve my problem, without having a seperate
    environment?

    Venkat,
    Actually, it is possible for Forte to listen on more than one IP andport
    combination. The first reply to your message was correct. If you
    set
    the
    FORTE_NS_ADDRESS to contain multiple entries before starting the
    name
    service, it will advertise on both. For Forte servers you use the
    FORTE_LOCATIONS env variable to get it to advertise on multipleip:port
    combinations.
    We were doing something very similar with another customer I was at
    to
    get
    around a firewall. I will warn you that there are some issues with
    FORTE_LOCATIONS that may keep that portion from working. However,
    from
    reading your note, it appears that all you need is for the nameservice
    to
    advertise and listen on multiple ports and that works fine. I justtested
    it again for sanity sake and it worked. I ran my test on NT using
    Forte
    3G2.

    Venkat,
    Technically yes this is possible, though not in Forte. A nameserver
    can
    only listen on one port.
    To implement this scheme you will have to write a proxy service (insome
    language
    including perhaps forte) which listens on the well-known port on the
    second card, reads requests, then forwards them to the realnameservice
    (wkp on the first card), and forwards replies back. This is not
    trivial, but some firewall toolkit vendors supply stub code to write
    application specific proxies.

    Subject: RE: Is there a way to have 2 network cards on the same machine
    My requirement is that my second card serves as best case performance
    testing piece. This eliminates the network completely. We went one step
    ahead and created a new enviromnent for the second card. Whatever I do, the
    nodemgr is returning back the IP address of the first card, even though my
    FORTE_NS_ADDRESS does not have the first card in the picture any where.
    I think Forte is doing a host look up and returning the first IP address it
    finds, as opposed to returning the IP address specified in the environment
    variable FORTE_NS_ADDRESS. Is there a way to trick it?

    OK, you ran into one of the issues. That is, if both addresses are known
    to
    the client that is trying to contact the partition it will always use the
    first address in FORTE_LOCATIONS. This is because FORTE_LOCATIONS was
    designed more as a failover mechanism. So it will always try the first
    address in the list and if it succeeds, there is no reason to move on to
    the
    second.
    Now, the second issue is that there is currently a problem with the client
    failover to the secondary address in FORTE_LOCATIONS. If the first entry
    fails it is supposed to retry on the second entry. Instead, it retries
    the
    first entry again. I know that Forte knows about this but I do not have a
    bug number on it.
    With that said, lets look at a possible solution for you. If the real
    objective here is to have a back up network card available for fail over
    on
    the same machine, or use one card to advertise outside your firewall and
    one
    to use inside, then you will have to contact Forte to determine when the
    failover problem will be fixed. But, if the objective is to load balance
    across the network cards you could have the environment manager listen on
    both ports and then alternate your server partitions across both cards.
    For
    example:
    set FORTE_NS_ADDRESS=card1:5000;card2:5000 and then start up the
    environment
    manager
    set FORTE_LOCATIONS=card1:0 (the 0 in the port causes the OS to pick a
    port)
    and start partition one
    set FORTE_LOCATIONS=card2:0 and start partition two
    and so on....
    In this scenario the environment manager will be listening on both cards
    but
    each server will be listening on only one of the two cards. So if a
    request
    comes in for partition1 it will go through card one and if it is for
    partition two it will go through card two. You could assign your
    partitions
    to cards based on expected load.
    Well, I am done. I hope this helps!

    Sean,
    Thanks for your reply. I tried the approach. I was not very specific in
    my
    question. I do need the ability for server applications to listen and
    server
    on both the network cards.
    I was succesfully able to make the nodemgr listen on both the cards and
    actually serve requests coming in from both the cards. But, following your
    advise, I took a cautious step with FORTE_LOCATIONS. Here is what I
    noticed.
    I have an application that has 6 partitions in total. I used
    FORTE_LOCATION
    to make it listen on 1. Both the cards. 2. Swapped the IP addresses for
    both
    cards for this application. 3. One card that I want it to listen on. I
    tried
    all approaches by exporting the locations variable for just this
    application. The nodemgr recieves a request from this pc connected on the
    second card to talk to one of the partitions. The node mgr responds with a
    proxy - with the ip address and socket number of the first card. The
    FORTE_NS_ADDRESS variable looks like this:
    IP1:5002;IP2:5002.
    Is it possible atall to resolve my problem, without having a seperate
    environment?
    Thanks

    Venkat,
    Actually, it is possible for Forte to listen on more than one IP andport
    combination. The first reply to your message was correct. If you setthe
    FORTE_NS_ADDRESS to contain multiple entries before starting the name
    service, it will advertise on both. For Forte servers you use the
    FORTE_LOCATIONS env variable to get it to advertise on multiple ip:port
    combinations.
    We were doing something very similar with another customer I was at toget
    around a firewall. I will warn you that there are some issues with
    FORTE_LOCATIONS that may keep that portion from working. However, from
    reading your note, it appears that all you need is for the name serviceto
    advertise and listen on multiple ports and that works fine. I justtested
    it again for sanity sake and it worked. I ran my test on NT using Forte
    3G2.

    Venkat,
    Technically yes this is possible, though not in Forte. A name server
    can
    only listen on one port.
    To implement this scheme you will have to write a proxy service (in some
    language
    including perhaps forte) which listens on the well-known port on the
    second card, reads requests, then forwards them to the real nameservice
    (wkp on the first card), and forwards replies back. This is not
    trivial, but some firewall toolkit vendors supply stub code to write
    application specific proxies.

    Folks,
    Here is what we would like to do:
    We want to have 2 network cards on a unix box - which means I have 2ip
    addresses, and the connection between the two is the unix box and onlythe
    unix box. I have a pc connected to the 2nd network card and I want it
    to
    connect to the nameserver that is listening on a well known port onthe
    first network card. We don't want to turn IP forwarding between thetwo
    cards. We want Forte to address both cards to talk to clients, in one
    environment.
    Can this be done? If so how?
    Thanks in advance.

  • Is there a way of putting firefox bookmarks folder on the dock

    Is there a way of putting firefox bookmarks folder on the dock. not just one bookmark. i have done that. but i want all of them in stack or something.. similar to how windows did it in the start menu. its annoying that you have to open firefox first to access your links.
    i got my first imac yesterday and loving it!!! albeit the text is a bit small but i have found the zoom!
    thanks in advance

    Perhaps you don't know how to bring icons into the Firefox  Toolbar. You can put many things up there, including Bookmarks. You can also remove an icon or rearrange the order of icons.
    From View>Toolbars>Customize
    Here is the Bookmarks icon (next to the History icon) from which you can open all your bookmarks directly. And if you can remember a keyword, it will find that one, or any others that come up with that keyword. It's really quite convenient to use and will stay updated with any new bookmarks that are added.
    This is showing the Bookmarks open, which can be closed by clickng on the small x.

  • Is there a way to create a collection based on the "previous import"?

    is there a way to create a collection based on the "previous import"? that would make it easy to mobile sync the last import to my ipad, and do further picking/rejecting while away from my laptop.

    well, yes, of course i could do it that way. i guess i wasn't specific enough. is there a way to create a smart collection, with the photos in the "previous import" as members of the smart collection.  earlier i mentioned about using this smart collection to mobile sync with my ipad, to do further flagging.
    so my intention, use a smart collection to mobile sync with my ipad, and the smart collection to include the photos from my previous import.
    i guess another way to ask the question, is there a way to create a smart collection, by using some rule or condition in the smart collection, to automatically include previous import photos.
    the documentation says that "previous import" is a collection, even though it shows up in the catalogue side bar section. but i see no way to choose that collection when making a smart collection.
