What are the objects javafx can be built in the init() method?

I have consulted the api javafx2.2, it says:

Threading

JavaFX creates a thread of the application for enforcement of the startup application, input events processing method and execution of the animation chronologies. Creation of JavaFX Scene and Stage objects as well as the change in the operations of scene graph to living objects (objects already attached to a scene) must be made on the JavaFX application thread.

Request of the manufacturer and init method is called on the thread of Launcher, not on the Thread of the JavaFX Application. This means that an application does not build a Scene or a Stage constructor or in the init method. An application can build other objects of JavaFX in the init method.

But exactly what javafx objects can be built in the init() method? if someone could make a list? Now I know, what objects except the scene, scene, Tooltip, ContextMenu, HTMLEditor and WebView. Is this good? Are there still other objects that cannot be built in the init() method? Thank you.

Things that need to be created on the JavaFX Application thread (cannot be created in init) are:

1 WebView.

2. anything that involves the creation of the window (balloon, the ContextMenu etc are all from the windows popup in their internal implementation).

Jira related question:

RT-17716 some controls cannot be created on the FX application thread

There are workaround solutions in the comments to:

RT-25127 ToolTip the tab (and other controls) cannot be defined in FXApplicationThread

    With Skype, your location is unimportant. Calls to (or within) the United States wherever you are cost 2.3 cents / minute or part of it.

    You can easily find the information yourself with a little research here:

  • What are the causes of error - OR-XNET: the NOR-XNET driver is no longer can communicate with the device.

    Hello

    I use X-NET-PCI8512, OS: Windows 7, C++ (middle of the QT interval).

    I'm pooling of card data (StreamIn member function) to ~ 100 Hz. card reading time (ReadStatus) to ~ 100 Hz.

    After about 40 min (depends on the amount of data in) I get this error:

    (Hex 0xBFF630B2) The NOR-XNET driver cannot communicate with the device. Solution: Make sure that the device was not removed from the computer.

    What are the causes of this error?

    Thanks in advance,

    Aviad

    Hello aviadCielo,

    When you get this error, what does do to make it work again? If you restart your program, start all this work?

    Secondly, what version of NOR-XNET do you use? It's maybe a software problem that could be resolved by upgrading to NOR-XNET 1.6.

    Finally, can you reproduce this problem with a simple program? If so, you can join the program you use?

    I am only a very lightweight browser and the user of the social network. I do not use my PC for something else.

    It is average for a system Windows does not.

    Windows is broken down into different components so they can be executed in parallel to improve performance.

    Their closure will cause your computer to malfunction and eventually fails.

  • How can I find out what programs I should have started and what are the programs I can start myself to my computer to run correctly when starting?

    * Original title: startup

    How can I find out what programs I should have started and what are the programs I can start myself to my computer to run correctly when starting?

    Hello

    I understand you want to learn about programs, you should start your Windows startup. I will certainly help you to question.

    When you start Windows by using a normal startup startup, several applications and services automatically, and then run in the background. These programs include the base system, antivirus software, utility applications processes system and other software that was previously installed. These applications and services may cause interference when you install or run a program.

    The system configuration is a tool that can help identify problems that might prevent Windows from starting correctly. You can start Windows with common services and startup programs turned off and then reactivate them, one at a time.

    I suggest you to refer to the links below and check if this is useful:

    Using the Configuration System (msconfig)

    Perform a clean boot to determine if background programs interfere with your game or program

    Hope this information helps.

    Please get back to us with an update on the issue, we will be happy to help you.

  • All the members (but 1) are removed from the entity dimension in planning and deployed to essbase. -What are the data deleted in essbase so? / The data can be restored by restoring the entity dimension?

    All the members (but 1) are removed from the entity dimension in planning and deployed to essbase.

    -What are the data deleted in essbase so?

    The data can be restored by restoring the entity dimension? EPMA the entity dimension is still in tact.

    It is unclear what exectly arrived, but looks like a change was made in the dimension entity planning (not EPMA) and then deployed (successfully).

    In essbase, we see that the entity dimension has only one member left for the appropriate plan types, as in the planning.

    If you remove members and then push that yes the essbase data is deleted, if you need back then you will need to go back to your restore process.

    See you soon

  • What are the issues and how can I put the documents in the files?

    As usual; Oracle is absolutely horrible in providing any kind of basic instructions on the use of the products.

    I need to upload files to a structure (don't care if it's collections, folders, or in mason jars as long as it works) and be able version them and seize those I want.

    I managed to get a variety of things to work with the genericSoapService (cannot use the API in accordance with local policy), but everything I check in goes in (don't know where)

    I don't think I'm even asking the right questions because my web researchers increase irrelevant results.

    What are the issues and how can I put the documents in the files?

    I created a few files like this:

    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ucm="http://www.oracle.com/UCM">
   <soapenv:Header/>
   <soapenv:Body>

<Field name="fSecurityGroup">RAFT_ADMINGrp</Field>
</Document>
</Service>
</GenericRequest>
   </soapenv:Body>
</soapenv:Envelope>

    Here's a sample call:

    The virtual path is/Appraisals/0111234567 /.

    The GUID for this folder is CBF8EF9C59F8A6C84EB31C68F0903399

    I see the reference to xCollectionID when I look for answers, but the data is not available for me (see the output below)

    When I run this it stores the file but the file does not appear in the folder.

    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ucm="http://www.oracle.com/UCM">
