Launch of several steps in the primary phase

I'm writing an application where multiple windows (steps) must be launched from the event handlers to the controls on the primary stage and primary is visible at any time, which is that I don't want to replace the scene. In addition, secondary steps must be modeless, and user must be able to interact with any stage, primary or secondary phase, at any time. Is this possible?

Hello. It is possible. Here is an example:

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.paint.Color;
import javafx.stage.Stage;

public class Test extends Application {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        Application.launch(Test.class, args);
    }

    @Override
    public void start(final Stage primaryStage) {
        primaryStage.setTitle("Hello World");
        Group root = new Group();
        Scene scene = new Scene(root, 300, 250, Color.LIGHTGREEN);
        Button btn = new Button();
        btn.setLayoutX(100);
        btn.setLayoutY(80);
        btn.setText("Create stage");
        btn.setOnAction(new EventHandler() {

            public void handle(ActionEvent event) {
                new CreateStage();
                primaryStage.toFront();

            }
        });
        root.getChildren().add(btn);
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

class CreateStage {

    public CreateStage() {
        Stage stage = new Stage();
        stage.setTitle("Many st");
        stage.setScene(new Scene(new Group(), 260, 230, Color.LIGHTCYAN));
        stage.show();

    }
}

  • How do go back (or forward) several steps without having to navigate in the history tree?

    Internet Explorer has a down arrow button (drop) next to the rear and the next button which allows to skip several steps back (or forward) in two clicks. How do I do that in Firefox? Navigation in the history for this simple task tree is much heavier.

    Concerning

    So, in your app (data model) module, you have a master relationship / typical retail:

    And the relationship between them is based on some ViewLink

    Now go to the ViewLink, relationship, accessor.

    Take a look at the Destination accessor.

    Generate accessor object to check and give a name Acessor

    Then go to the master VO, Java and Include accessor, the class generate a display line:

    Go to the class view Java generated line, you'll find a method with the name of the accessor of the previous step, in the form of:

  • Comparison of the data of several rows in a table - based on the primary key

    Currently I have a select statement that returns hundreds of records.  Each returned record is linked to A NUMBER of ORDER this order number has a recipe.  (a bit like a cooking recipe).  Each recipe has many records in the database related to this order number and records should be compared to records in a table that bind to a specific primary key...  (I have already developed the logic to isolate what PK I need).  If all these records that are returned by the select statement below does not match all the records containing PK in the table below, I need to get the next PK and compare all these recordings for select statements return.

    See below for a better understanding. Need a good example detailed on how to solve my problem here.

    Just to help you understand:

    Each element of the recipe is 3 parts (side, ref_des, part_number).  1 single recipe can have several parts (where the part_number), and each of these pieces should be placed on the lower side or top of the Board that is there "side" comes into play.  Same thing with Ref_Des.

    What is going on

    Select statement returns the RECIPE of ORDER NUMBER A.  There will be multiple records returned by this query.

    Select the Return statement:

    • Side
    • Ref_Des
    • Part_Number

    Example of return:

    B c17 75145-2

    T f14 89242-8

    B s12 45123-3

    etc,

    In general - what I need to do:

    There is a table called AUTO_RECIPE_DETAILS.  I take all of the records returned by the select query above and compare for each record in this table relating to the recipe 30319-000001.  30319-000001 a number of records.  It is the primary key for a whole recipe as seen above.  This primary key is bound the number of data records in this table.  The comparison is to see if all records under RECIPE_NAME 30319 -000001 match all the records returned by the select statement.

    IF IT DOES NOT MATCH: recover the following recipe in this table below 30319 -000002 and make the same comparison.

    Here's a perfect example of what the table looks like: (AUTO_RECIPE_DETAILS)


    RECIPE_NAME SIDE REF_DES PART_NUM

    -30319-000001 C16 87595-1 B

    -30319-000002           T B14 74150-4

    -30319-000001 T B14 34251-2          

    -30319-000001            T F24 84180-7

    -30319-000002 T B12 13710-8          



    It is the solution to my original question.  By this thread, it's the right answer and I hope this helps someone who is trying to compare two arrays element-by-element.  In the end, the advice given in this thread were correct and I will be using all of your suggestions and the scrapping of this.  Thank you everyone for your help though.

  • Registration of the OAM Self, collect information about several steps

    Dear,

    I have a question for the self-registration in Oracle Access Manager 10.1.4.1, I want that the user enter his information on two screens, it will first enter a unique identifier (I'll call a program through the event of identification API to make some validations on this identifier), then on the success of this program, the user must enter his name of user and password to continue the self-registration process

    When I tried to do 2 steps in the cmdlet workflow, the first is to inform with a field and the second is to provide information with the name of user and password fields but the problem is that the second stage is only accessible from inside the user application as a ticket not turned Manager and still , the user does not have name of user and password to access the User Manager, then how can it be implemented?

    Thanks in advance

    Since you split the self-registering on 2 pages, you can transmit the coordinates of page 1 to page 2 and create and identity XML in page 2 to invoke the self-registration workflow (created in OAM).

  • Why can I no longer apply ratings to several photos at the same time?

    I used to be able to select several images and their add the same note at the same time. Now a single image will have the side has changed. Why?

    Opening 3.6, El Capitan

    Disable the single primary indicator.

    See this: keywords or ratings are only applied to one of the selected images - why?

    The reason is usually that the "Primary" indicator only is defined. With this option enabled, the changes by using the keywords, notes and other metadata will be applied to the only "primary selection": the primary selection is the active image selected. This image is marked by a thick white border in the browser and Viewer, see paragraph "navigating through and selection of Images" in the Manual of Aperture 3.

    To enable or disable the "Primary" indicator only, toggle the button "Primary only" marked by a '1' in the display controls, or use the main menu to open bar:

  • 7520 new stuck in the installation phase. Print head move load ink cartridges

    I'm stuck in the new phase of printer configuration. After running through the commissioning of questions and I opened the cover to charge the ink cartridges and the print head did not move. I ran across several reset process... Unplug the printer. Wait 60 seconds and plug it in again. Browse the configuration... Unplug the printer... more.

    This printer does not seem to be any cartriages.

    Hey JohnTT,

    Sometimes, these printers come with packaging that holds the printhead completely to the right at the gas station.  This avoids damage to the product during shipping.  You see all plastic parts orange that it may contain in place or Blue Ribbon?

    So, have you tried the carriage to the right hand?  Can it be moved or is it blocked?

    If the printer still will not release the print carriage after the power cycles and move it by hand, then I suggest you return the product and return to the retailer of purchase or by calling the HP Technical Support to see about a replacement.  The phone number for the USA / Canada residents is 1-800-474-6836.  If you are not in this region, click here.

    I hope this helps.

  • Re: Satellite R630 cell phone recharged by himself several times during the installation

    Hello

    I own a laptop Satellite R630 155. I just recover my machine with the procedure for recovery of HARD drive, and in the last step of the installation from the progress bar indicated there are 54 items to install. After every 2-5 elements installed my laptop recharged by itself several times until all of the 54 have been made.

    Is this normal? I expected everything to be installed only once before a reboot was done.

    Yes, it's normal. The same thing happen on my Satellite A660.

    You must understand that nearly 60 different drivers, tools and utilities must be installed and some of them need installation restart and finished mobile.
    If you have installed the OS and drivers manually, you must know this notebook or PC restart after some driver installation must be made.

    I know, it's a bit boring and facilities for all take a lot of time, but... This is normal.

  • Arm movement is recognized as steps in the application of the activity on the Apple Watch?

    Happy new year to you all

    I am the happy owner of a Apple Watch OS2.1 running, but I think that the watch records the movement of the arm as the steps in the
    Fitness app?

    Today I was at my desk and moved no more than a few times get coffee (10 steps), the application of the activity
    the clock tells me that I moved 1 659 equal to 1.47 KM steps and I have
    a hard time to see this may be correct (work of my office at home, so basically
    went to my room to my office (max 50 markets)

    the data GPS on my phone, but the problem is the same, someone else has the same type of questions?

    Look forward to the thoughts of entry or comments, you may have.

    Hello

    Happy new year!

    In addition to the calibration of your watch, it is also important - for more accurate estimates of activity - to ensure that your personal information is correct. To verify that it was entered correctly and update over time:

    -On your iPhone, in the application of Eve, go to: My Watch (tab) > health > edit (top-right).

    However, it is possible that the numbers you quoted are correct. Even with a relatively sedentary lifestyle, regular movement around the House or at work can soon add up.

    To check the data behind the totals:

    -On your iPhone, in the application of health (not the application of the activity), go to: health Dats (tab) > Fitness > steps.

    -The graph shows your steps per day, week or month (use the tabs at the top to change that).

    -Press show all data to view data for each day.

    -Tap on a day to see each data point, along with the data source (for example, iPhone, Apple Watch).

    When you present data in the dashboard, where data for any particular measure were available from several sources at the same time, the only health of them, app chooses automatically in order to avoid double counting.

  • Install Windows 8 on external drive Thunderbolt - Windows could not prepare the computer to begin the next phase of installation

    Hi all

    I'm at my wit's end trying to install windows 8. Let me start at the beginning: I used to have windows running on my Mac Pro ssd internal 8.1, installed via bootcamp. It worked well for a while, and then refused to start, gives me a blue screen KERNEL_SECURITY_CHECK_FAILURE. Despite some advice from lonely T, I was unable to fix and ended up wiping the partition and relocation, again via bootcamp. Yet once again, it worked for a few months, then the same problem. I made this one last time, and it only lasted 2 days... So I gave bootcamp.

    I think that the hybrid MBR partition scheme that implements bootcamp is the culprit, but I don't really have evidence to substantiate this claim. In any case, I tried to install windows in EFI mode. (If I understand correctly, the hybrid MBR is set up to allow windows to install in legacy BIOS mode, but that windows 8 may now install efi, which supports my Mac Pro mode.) My Mac is the new Mac Pro (end of 2013, trash in shape), and I can say short UEFI 2.0 (I have the latest efi update from apple installed).

    The method I'm trying:

    1. create a new partition in HFS + on my external drive using disk utility. The drive has now it's efi partition and partition empty 750Go I want to install windows a 1.25 TB storage partition that I use with my mac. It has a GPT. I formatted HFS + and no FAT, because I think that disk utility creates the same hybrid-MBR as training camp every time a FAT partition is created.

    2. use gdisk to confirm that the disc does not have a hybrid-MBR. (sudo/dev/disk1 gdisk watch MBR: protection)

    3 restart my mac and hold the possibility to put in place to bring up the boot efi menu.

    4. Select the EFI_Boot DVD icon (that's the windows 8 install dvd that I have in my superdrive USB drive)

    5. go in the menus of the disk selection screen installation and delete the partition in HFS +, I created to install windows on (the format option is not available)

    6. now select "Unallocated space" on the good drive and click Next.

    The problem:

    Partitioning seems to go ok (there is no feedback on this basis, but it proceeds to the next screen, and all new partitions expected are there if I check diskutil list later). He said it is "copy of windows files", but then stops with the error "Windows has no prepare the computer to start the next phase of the installation." To install Windows, restart the installation. "If I restart, I can start the same process all over again and get the same result.

    The Question:

    How I get this error and get windows install?

    Extra pieces:

    • The first time it happened I assumed it was the new sip / thing "without roots" in El Capitan, causing problems, then I disabled, but I still get the same error.
    • After reviewing the diskutil list output after one of installs it without success, I found that a labeled EFI partition has been created after my storage partition (the original efi partition was still there in the upper part of the disc).
    • I have windows 8.1 installed now bootcamp on my internal ssd. It was planned to use it and winToUSB to put windows on my crush, but I found that it only works with usb2. I do not have installed could cause problems with the installation on another disk.
    • Before say you I can't run windows on an external, yes you can, and many people have. I read windows sees thunderbolt internal disks.
    • I read a few other posts on this and other sites on this problem, but could not find a pertitnant solution to my situation. I found one that suggested to remove the efi on my disk partition, but that seemed like a bad idea, so I didn't try.
    • I write this at 1 in the morning after a day spent in front of the computer trying to get this working, so please excuse typos typing or other. I am pleased to provide you with any pertinant information helping you will help me.
    • Thank you!

    The other thing I tried also almost succeeded:

    Although I prefer to get the method above works, because it seems the most promising, is something else, I've tried that I thought worth mentioning. If you offer advice pertaining to this method rather than the above, I would appreciate it if you could explicitly declare that at the top of your answer. Thank you.

    I tried to install windows on the physical disk using vmware and virtual box. The instrutctions I followed for this can be found here: http://www.andrewsavory.com/blog/2011/2156 (the only thing different, it's because it's on an external drive, I created the Fat 32 partition manually using disk utility). The first time (using vmware) installation seems to go off without a hitch, but I couldn't get my computer to see the windows partition as bootable with the boot efi menu hold-option regular refined or with system preferences-> startup disk. I think that I was using always inadvertently a hybrid-MBR at this stage. I tried to repeat this new beginning with the first two steps above to avoid the hybrid-MBR. But now when I try to create the virtual machine based on the gross vmdk, it starts to copy the files then says not sufficient permissions and fails. I don't know if it's a permission with the disk or the hard problem. I tried chmod 777 and chown $USER of the vmdk disk (/ dev/disk1s3) does not.

    Wow, that was a long post...

    1. when a second drive is detected by the Windows Setup program, he wants to create his own brand of EFI (104 MB) and not to mess with the Mac EFI (200 MB). You can force it to use the EFI to the Mac using Diskpart commands.

    2 instead of HFS/FAT32, create a piece of 750 GB free space and it should only get a new MSR/MSD, without the part of EFI.

    3. on your VM method, the link you have is quite old. You have a MP 2013, with references to the 2010 Mac alumni and is a bit too archaic to be useful. http://forums.macrumors.com/threads/install-a-Windows-7-partition-on-Mac-OSX-Wit hout-optical-car-or - usb.1836959 / #post... seems to work for many and can be useful for a test. It also uses Winclone.

    Use a tab on your front control.  A tab for files, one for hardware init and one to run it.  You will have only a block diagram, so the data are readily available. Any wire it where it needs to go.
