Destroy / has WebView

Hello
Is there a way to destroy an instance WebView? If a page loads, and say a video begins to play, I want to be able, when I hide the WebView, essentially to destroy, or at least reset.
I know that I could listen to the visibleProperty and do a getEngine () .load)
But I was wondering if there was something better. Also, the visibleProperty does not change if the (false) webView.setVisible is executed just? He does not, for example, that the parent node of the not visible a webview.
Appreciate your help.

Well, there are two things here, we're not having it visible on the screen and the second that you can refer to what the trash of the object collected.

(1) don't have not visible on the screen just delete what ever parent node it is in.

someParent.getChildren().removeall(myWebView);

or you can set the opacity of your webview to 0.

(2) If you want t be the garbage collector, then you must remove all the references, you may have to it. This includes all collections (lists, sets, maps), tables, variable object and static variables. This topic goes beyond JavaFX and you can search further under the heading of collecting garbage forced or something to that effect.

In addition, you can refer to something that is more specific to the Web format and its webEngine... like for example delete the webEngine of any page it can be loaded. I have not tested with webEngines but I do not see a clear method of sorts that turns off the screen. Loading may be NULL can turn off the display?

Thank you
Jose

  • How to insert images in the content pane HTMLEditor?

    How to insert images in the content pane HTMLEditor? or a hyperlink?

    > know the position of the caret

    Well, there is no public API on the HtmlEditor to know that.

    You could create an tweak asks to add such an api.

    In the meantime, I believe that the HtmlEditor is implemented as a contentEditable has WebView below, so I think it's possible to hack together a solution if you want to.

    To do this:

    1. create a program that uses the HtmlEditor.

    2. run the program and use ScenicView to work on the css to display embedded Web search path.

    3. Once your HtmlEditor appears on a scene, use a node search to dig up a reference to the Web view.

    4. Once you have a reference to the Web mode, use executeScript to get the position of the caret by using JavaScript.

    5. Once you know where the caret, use a mechanism similar to my example program above to allow you to insert an image to the location of the caret (get the html text, put the position appropriate, up-to-date then set it again).

    Of course, you don't need to use a HtmlEditor control to do this, you can also just use a plain WebView with contentEditable flag put on it or any number of 3rd party JavaScript html editors have image insert functions.

  • 9.3 update installs malware?

    I've updated to Reader 9.3 on Windows XP. After installation, the program opens automatically. Spybot Search and Destroy cancelled and delete the executable file for the program. The question is as follows:

    Spybot Search and Destroy has met and put an end to a process that is part of a malicious software.

    Process ID: 3536

    File name: AcroRd32.exe

    Found in: C:\Program Files\Adobe\Reader9.0\Reader\...

    Identified as: WarezP2P.cck

    Then, it was recommended that I have delete the associated file, I did. Now, when I try to run the program, it says that it cannot find the file AcroRd32.exe.

    I would like to know if the WarezP2P.cck process is supposed to be installed with the drive, or is it malware which should have been deleted? If this needs to be corrected, please e-mail me to let me know that the program has been corrected.

    Thank you.

    That's all just a false positive. Spybot Search and Destroy seems to have a lot of people (with many applications). You will not get a malicious software as you download directly from Adobe.

  • My flash drive which was a backup of my system windows has been accidentally immersed in water. When it is dry can still be used without destroying my USB port?

    My flash drive which was a backup of my system windows has been accidentally immersed in water.  When it is dry can still be used without destroying my USB port?

    Hello

    Put it in a bag of rice for a few days or more. -seal the bag.

    If you remove all the moisture, it shouldn't affect the USB ports if nothing is
    possible. Usually it is not a problem if the moisture is removed.

    I hope this helps.

  • Can I use my Win 7 Upgrade disk to do a clean install on my desktop that my old laptop has now been destroyed. ?

    Ok.. I bought a laptop with Vista pre installed Sony.

    Then, I bought a copy of Win 7 Upgrade to upgrade, I did.
    Shortly after, my laptop broke and I got a new laptop through my insurance company which had Win 7 pre installed. I just got a new desktop PC and was wondering if I could use my Win 7 Upgrade disk to do a clean install on my desktop that my old laptop has now been destroyed. ?

    As long as the original computer disappeared, I think you can use the upgrade on another computer...

  • Installed FF 8.1. It has DESTROYED MY ABILITY to OPEN MHT filesUnable

    I am so tired to it.

    I just installed FireFox 8.0.1 and it wiped out my ability to open MHT files. I HATE WASTING TIME WITH THIS GREAT DEAL.

    I downloaded Word Viewer 2007 and installed but it does not work either. All I get are some of the icons on the page.

    HOW CAN I OPEN THE MHT FIREFIX 8.0.1 FILES

    Yesterday, it wasn't a problem. I had an earlier version of Firefox 8 is installed. I think I solved this problem before but can't remember how I didi it.

    Right now I have a lot of work to do and I don't like screwing around with this problem.

    IE Tab 2 has an option called Sites filter - you need to remove / disable the filter for files ' mht | MHTML"or IE Tab 2 blocks them and they never open.

  • Apple has literally destroyed my mac

    So, this happened:

    My mac was perfectly fine, sometimes it would be heat just for nothing. So I contacted the suport of apple. Then I had to hold in Options-command-shift. Then my fan started for nothing, I shut down the computer during the night, and the fan was still when I started the computer. (Remember it's Apple's fault), my battery decided to not charge sometimes and sometimes charge. It took literally 5 minutes to stop the 1 program (Chrome, for example). My mac gets really hot, the fan does not turn, when it's really hot it turns. Also my speakers started to does not, sometimes, even if I had my WE sound. Can you help me solve this problem, should I call Apple and tell them?

    I have a macbook air 11 inches, mid-2012. El Capitan 10.11.4 version.

    Sounds as if the troubleshooting procedure, they told you

    Try, revealed a problem that may require the replacement of material.

    Whether or not "Apple" caused this symptom or not, it allowed

    Service provider Apple or affiliate trained Apple repair center is

    where to go for a better understanding of the real problem.

    I do not suspect that apple caused anything, other than offering you

    try and make a certain troubleshooting (reset) that revealed a

    problem. The unit needs to have a thorough diagnostic run on it;

    and the tech shop time for that regularly service costs to the owner.

    Have you tried other startup keyboard shortcuts to see what others

    results can occur?

    An SMC reset may help in some cases

    • Reset the management system (SCM) controller on your Mac - Apple Support

    Reset the NVRAM may be useful in another

    • How to reset the NVRAM on your Mac - Apple Support

    However most of them would only determine if a problem is

    in software or hardware. If you can't do the latter, an expert

    should then and you could detail exactly the problem without any type

    blame on the other; After all, you're here with your fingers on the buttons.

    There are a few other things that you might try, as an Apple diagnosis

    test; Breast OS X from the computer. You may be able to use OS X Recovery

    and use it to run disk utility and verify the material to some extent.

    These would be useful to a professional, who can understand the results.

    In any case... as another Mac user or non-voluntary who has

    taking time to respond to almost 01:00 hour (I am a person of day)

    I hope you will take the suggestion to try again, with perhaps another

    Provider of Apple which has a centre authorized service, personal.

    Good luck in this case!

    ·        If the PQService partition is removed using fdisk or a utility under Windows, you may need to reinstall Windows.

    ·        If the system is recharged using the DOS version you retain the eRecovery feature
