componentcanvas is not drawing components in addition to other fields

Hello

I try to use ComponentCanvas to make a button at the top of the video field.

but it is not drawing field above it.

It is add field componentcanvas first, then adding videofield.  behaves as verticalfield Manager.

If someone can give me right way to use componentcanvas as I couldn't find any docs appropriate use.

Thank you.

I find a way some overlap buttonfield on camerafield.

I used ViewFinderOverlay for this purpose.

Here's the code I used:

if(_cameraField != null)
        {

                try{
                overlay= new ViewfinderOverlay(_cameraField);//used viewfinderoverlay
                overlay.getCanvas().add(new ButtonField("KD"));
                add(overlay);
                }
                catch(Exception e){
                final   String msg=""+e;
                    Application.getApplication().invokeLater(new Runnable() {

                        public void run() {
                            // TODO Auto-generated method stub
                        Dialog.alert(msg);
                        }
                    });
                }
}
        else
        {
            add(new RichTextField("Error connecting to camera"));
        }

  • HP 8500 has more scan not scan - I hear a fast spin and the book will not draw in the charger

    HP 8500 has more scan not scan - I hear a fast spin and the book will not draw in the charger. I tried a reboot, including disconnect the motor from the power analysis. A software update was just pushed through today as well, but the problem with the scanner was before this update. This update took place after the power has been turned off, then on again.

    The problem occurred this morning during a prior scan + back. I heard a click or pop/fast spin, something that indicates something was wrong, when he tried to feed on the 1st backsheet through for the scan of the back. Now, it won't take what anyone, even to make a copy using the feeder.

    When I look at the roll holder bar above paper, I noticed that it does not drop down to make contact with the paper he move to the scanner itself. I remember having this problem once before - there are 2 years, while the warranty was still in effect and does not remember how it was resolved.

    Any suggestions would be welcome. I don't want to buy another printer just to get the scanner to feed again. The printer itself is fine and scan from the bed is not affected.

    For anyone interested, I sloved the problem of roller scanner do not push the paper into the ADF.

    I turned off the printer last night. Today, I removed the power cable at the back of the printer and then unplugged the power cord from the wall. It was off for about 30 minutes. I reconnect the cable to the printer and the wall, the printer running and waited about 10 minutes. So tired the charger scanner again. It worked and I don't know why.

    Yesterday, I tried a version of what I found in the documentation for HP support. He said to do, but not to turn the printer off first. He has not worked for me.

    I don't know if my path has really had no effect on the results, but it works now and I don't have to think about buying a new printer for awhile yet. I like this idea!

  • could not draw a custom in PF_Window_LAYER user interface

    Now I'm developing a custom user interface plugin.

    I draw a red circle or a green rectangle in a layer window as a custom for my objects handling control.

    There is no problem to draw a custom in a composition window user interface (w_type == PF_Window_COMP)

    But I failed to draw a custom in a layer window user interface (w_type == PF_Window_LAYER).

    To ParamsSetup(), I put PF_CustomEFlag_LAYER to ci.events.

    Transformations of coordinates works well (I think).

    It just seems to not catch a PF_Event_DRAW.

    Why?

    I tried the simple example of custom user interface, "CCU" plugin which is included in an AESDK (CS3).

    Also, CCU plugin seems do not draw a custom in a layer window user interface.

    AE CS3 and AE CS3 of SDK.

    Visual Studio 2005 Pro

    Win XP SP3 32-bit

    Hi dfurusaka.

    as far as I know, it's a bug in cs3 and cs4, which has been fixed in cs5.

    order some other plug-ins that have an interface user custom, like 'meshwarp' or 'vector paint. they don't too draw in the window of layer on cs3 and cs4.

    If I remember correctly (it was a long time ago), I looked inside and saw that the plug-ins receive a call for display, but the return buffer is simply ignored by AE.

    I have never tried to solve this problem, so I can't tell you if there is a solution, or it's just something you have to accept.

    Well, at least you know that it works in cs5...

  • Why is customer e-mail apple suddenly not remember passwords from email accounts other than iCloud?

    I have MacBook Pro 3 to all the excellent - 1 since 2009.  Suddenly the Apple Mail Client is asked for a password for each e-mail account, except for the iCloud account.

    I know that the email and password is correct, because my iPhone 6 s email client continues to download and send emails from all accounts in mail without problem.  In addition, I can go directly to the e-mail page in the browser, for example, www.hotmail.com to that email account and the MacBook Pro connection directly on this page.

    I tried to close all the computers down to reboot hard and using disk utility to check the disks.  I also changed all the other 3 accounts 3 times: and won't do again - too much work and does not.

    I downloaded Malwarebytes for Mac directly from Malewarebytes and updated definitions and ran the program.  The results were negative.  This shit started after RAW last download security in which a group has found a security flaw in one of the types of files to Apple.  I can't help but wonder if that had anything to do with it.

    Anyone had this happen; and someone has other suggestions as to what's going on please?

    John

    PS I have a time Machine that is supposed to be back up all 3 of Macbook Pro. (1 to) but I have never tried to use a backup, then it would be something new for me, if anyone thinks it's necessary.

    It is quite common. Mail most likely simply lost the password and must be entered again. However, sometimes it is the Keychain Access.app.

    Windows in the Menu bar select connection doctor. You will see two entries for each account - 1) reception and 2) sending SMTP.

    The Red icons will tell you where the password is missing.

    • Incoming is set on the main window of account under the account information tab

    • The outgoing is set under parameter edit SMTP.

    CHANGE THE INCOMING SETTINGS

    In the window account under the account information tab, enter the password.

    Click to save your password.

    Check the connection doctor to see if your incoming connection now works.

    CHANGE THE SMTP SETTINGS

    In the window accounts > outgoing mail SMTP server: Select this option to list edit the SMTP... of popup.

    Select account from the list. (It is not uncommon to find additional SMTP servers listed. When you delete the account, E-mail does not delete smtp info. You may need to do some cleaning in the list to remove the extra cost).

    On the Advanced tab:

    Apple uses by default the default ports (25 465, 587), but some servers prefer a custom port. Check to see which port they recommend. For example, Gmail like 465, 587 Outlook.com.

    Check if your server requires SSL.

    Username. Enter the full e-mail address for example.  [email protected]

    Add password if it is empty. (If you have configured authentication two step, you will need a password specific app)

    (there is no registration not required when adding password here0)

    Open connection doctor to the title of the window in the menu bar.

    Think you that green light now for your SMTP account?

    If you still have problems...

    Keychain problems

    This to fix the repeated requests of password...

    Open Keychain Access, in Applications/Utilities

    Search for your account. You might find several. Normally you have not more than two. An incoming and an outgoing.

    Registration by e-mail have blue @.

    Example:

    Delete all entries. The keychain is not smart and keep all the old entries when you add / modify a password.

    Open Mail and enter the password of your account. Enter account account information and settings to modify SMTP Advanced tab tab

    Password should stick now.

    Note: Keychain first aid no longer exists in El Capitan.

  • Bitmap image does not appear when other fields added

    Hello

    I have a VerticalFieldManager with a bitmap and a few fields (code below).

    The code below when the bitmap is set, the other fields, move to the

    I have it! Had to extend Manager rather than VerticalFieldManager. Assumes that the optimization of the resources are so limited in-house as how fields can be arranged. Makes sense.

    Hi guys,.

    When you type information in a form in the DC or Pro Player I can enter text with fields of text etc and then save, close and return later to change the form. However once I use the function "Fill & Sign" to sign the document, and then save, it locks the file and all other fields become editable. Is there a way around this to remove this feature where it becomes locked and instead allows me to change the form after a signature is applied and saved. All the security properties of the form are on 'admitted', there is no restriction. Even though the document is locked all the properties remain still as 'authorized '.

    The signing is FINAL.  You cannot sign a PDF paper advance. Complete and save, do not sign.

  • In the form of domain information does not, unless the user clicks on the field?

    Hello

    I got PDFs with form fields that contain text. In the past, all the text is visible and if more text is in the more visible area, you get the scroll bar.

    The last document I received, the text does not appear, until I actually click the biox field. Once I click on the field, the text and the scroll bar appear, but once I click it disappears again? We cannot understand why?

    Anyone know how or why this happened and what is the solution?

    Thank you!!

    Babs

    This works because it gets Acrobat to redesign the appearance of the field, which is the problem. Preview does not correctly save the PDF file and field appearances can get damaged. Importing data in causes Acrobat to redesign the field, partially correct things.

  • Burrito of flash builder design mode is a white screen and does not not all components

    Hey guys, for some reason none of my components appear any, when I go to design mode in flash builder burrito, and the screen is white. When I run the app, it works very well and seems very well my only problem is that I don't understand what is happening in "Design Mode". Someone has a similar problem to this, also, I don't get any errors about not being not able to load the design view just a pop-up that says that it takes a while to load and to continue or not. The only time I see a component is when I go to the source and highlight a component then go into design mode, then u see a blue outline of the component. You can see in my screenshot above. Any help would be great, thanks in advance.

    Thanks again,

    Design mode does not work if you include qnx libraries in the path of the libraries due to a bug in FB, there is a flag to uncheck (qnx libraries) in the project to BBT properties

    It's really weird. Especially if it happens on all of your applications. Can you try to uninstall, reboot your iPad, and then reinstall the application? (Just make sure that your work is synchronized, you connect to http://assets.adobe.com ("draw" My Active - Mobile Creations)-.

    While you do so, I'll leave a note for the product team.
