Refresh the included tab Page

Hi all:

I have a page of fxml with a TabPane element with two tabs tabOne and tabTwo:

< BorderPane fx:controller = "lc.controllers.ControllerOne" xmlns:fx =" " http://JavaFX.com/fxml ">

< center >

< fx:id TabPane = "tabPane" >

< tabs >

< tab fx:id = "tabOne" liquid = "false" >

< text > < / text >

< content >

< BorderPane fx:id = "agendaBorderPane" / >

< / content >

< / tab >

< tab fx:id = "tabTwo" that can close = "false" >

< text > TWO < / text >

< content >

< BorderPane >

< center >

< fx: include source = "tabActions.fxml" / >

< /Center >

< / BorderPane >

< / content >

< / tab >

< / tabs >

< / TabPane >

< /Center >

< / BorderPane >

As you can see above tabTwo has a separate included in fxml.

Now the content of the tab in tabTwo should be updated based on actions performed in tabOne. But however included class action tab initialize method is called only once for the first time when the fxml page load. Can someone give a hint about how the initialize method of tabActions.fxml can be forced to run whenever the tab charges?

Enjoy it!

Thank you.

You can inject the controller for the included fxml (tabActions.fxml) in the controller for the main fxml. You have a fx:id attribute to the fx: include element:

Then in the ControllerOne class:

public class ControllerOne {
    @FXML
    private TabActionsController tabActionsController ;
    // ...
}

Here I assume that your references to tabActions.fxml a = fx:controller class controller "TabActionsController". The rule for injection is that if the fx:id FX: include is fx:id = 'x', then the injected controller has field name "xController" (fx:id = "tabActions"-> tabActionsController). See the documentation FXML on nested controllerssection.

This allows you to do what you want, because now you can define (and expose) the functions needed to "Refresh" in your TabActionsController class. For example:

public class TabActionsController {
    @FXML
    private TextField textField ;

    public void initialize() {
         // ...
    }

    public void refresh() {
        textField.setText( /* some default value, or etc. */);
    }
}

and then:

public class ControllerOne {
    @FXML
    private TabActionsController tabActionsController ;

    public void initialize() {
        // ...
    }

    @FXML
    private void handleRefreshButtonAction() {
        tabActionsController.refresh();
    }
}

  • Why can we not have subdomains on the new tab page more?

    With the last update to the new tab page, they removed the ability to go for subdomains. For example I can't have abc.com/news, abc.com/sports, abc.com/weather or something similar there, I can go to abc.com

  • Can I re - set tabs in the "New Tab Page"? I deleted all bookmarks in two of the nine "tabs". Can I re - define these?

    This new tab page allows to store the new bookmarks, right? But I was hoping to return to a bookmark that I jumped, so I pressed on remove again and again until the screen on two of the nine just went completely blank, and now I can't drag a bookmark for them. If I drag a bookmark to one of them, or anywhere else on the page, nothing is saved to the "new tab page", it opens just this bookmark. I don't know what I'm doing wrong. I have the window "Show all bookmarks" open. I'm puzzled.

    Hello

    Please try this: open a bookmark and drag its icon site (on the left side of the address bar (address)), hold it on the newtab tab and when it opens, release it on a blank thumbnail.

  • Is it possible to have the new tab page is displayed by default when you start Firefox?

    Firefox may be set to view the new tab page when the browser is started? In Options > general, the only choices under "Startup of Firefox" is the home page, a blank tab or restore previous session.

    Alternatively, the new tab page is adjustable as home page?

    The value 'When Firefox starts' to 'Show my home page' and 'Home Page' "subject: newtab".

  • How can I get the default for the new tab page when there is no improved/classic/empty choises when I click on the gear icon.

    When I open a new tab, I used to get a page which had tiles for some of the sites I visit often. Now I get the Bing search page. The help of instructions say I can change the default new tab page by clicking on the gear on a new improved, classic, or blank page icon in a drop-down list. When I click on the train, I don't get this list of options. Instead, a settings page appears, allowing me to make various changes, but improved, classic or white new tab page choices aren't there. What should I do?

    To modify the new page tab, please follow these steps:

    1. Go to about:config in Firefox
    2. Locate the browser.newtab.url string
    3. Set the value of this string on the URL of your page to the desired tab

    This should change the new tab page.

    Notes:

    • Set the about:newtab to get the page of the new classic tab
    • Set the about:home to get the default home page
    • Set the about:blank to get the blank page

  • How can I put ONLY 9 tabs, NO 15, on the new tab Page?

    How can I put ONLY 9 tabs, NO 15, on the new tab Page?
    (First OFF... Please do not read this as being written by an angry person.) I'm just frustrated with the browser that I liked for years. I hope someone can help me)
    For a long time, I had my Firefox (version 33.0.2 - even if I don't remember getting mentions "update") defined so that every time I clicked on the tab new symbol '+' to create a new tab (which has the "new tab Page" on that), the NINE inch nails would be shown for my SELECTION and PIN sites. I LOVED!
    Yesterday, I opened Firefox and NOW when I click on the '+' to open the new tab Page... FIFTEEN thumbnails appear, 5wide x 3down, (and to be honest I probably would have the habit of 15! ha).
    Here's the PROBLEM: NONE of the thumbnails are "compressed". They ALL have "liberated" up yellow icon to the left and clicking on does nothing to remedy this of course. Other that THAT, everything else behaves normally. (that is to say moving the thumbnails, deleting, swap... I just can't pin THEM!)
    FINALLY, I prefer my 9-repositionable decals on the new tab Page.
    I went through ALL the options on the side, upside down and backwards, and I just get more frustrated.
    Can someone help me?

    Hello

    If you can see all your tiles, you can change your settings in settings page:

    1. In the address bar, type Subject: config and press enter. The subject: config "this might void your warranty!" warning page may appear.
    2. Click on I'll be careful, I promise! to keep the comments: config page.
    3. Search for browser.newtabpage.columns and change it to 3, or however many columns you like
      • Note: browser.newtabpage.rows allows you to change the number of desired lines as well

    You can also set a fixed number of tiles with the following extensions:

  • How can I reset the new tab page? (Browser hijacking)

    My browser has been hijacked recently by Trovi search engine, and it changed the home page and the new tab page. I was able to restore the home page, but the new tab page was more complicated. I tried to go to about: config and replacing 'browser.newtab.url' 'about.newtab' (because I want the page with websites frequent return), but it just resets the site you'll find once I clicked OK. I tried editing that it again, this time with a URL, but it resets again. This continued even after restarting Firefox. Finally, I tried the add-on "SearchReset." He wiped my regular home page, but the new site of the tab is always you'll find... Whatever I do, it will not change. It keeps resetting to Trovi.

    You must remove the malware that Trovi hijacker.

  • How to create/add sites to the "new tab" page?

    I followed the link to help you guys already created. He asks to go to the window "Show all bookmarks" and drag a bookmark already created a vacancy in the "new tab" page. This does not work for my PC as once I drag the desired bookmark, just open this page on the new tab page. Please help with adding new tiles to the new blank tab page.

    I thought about it.

    I can't find anywhere in the manual where it says that Firefox must be set on remember the story so that it works. But he does.

    I put the tools-> Options-> life private Firefox Will: do not forget history

    and it works very well.

    I can understand why remember the story must be about to have FF build this list automatically. But why must it be to build this list manually?

    Well.

    I recommend FF to update their documentation.

  • How to make only ONE tab open every time I start Firefox - still, my screen jumps to the new tab page, although I tried to turn it off?

    I recently had internet service for the first time in two years. Over the two years, I took my desktop computer 4 times for a friend and got the updates that were available for AVG, HP, Windows XP, Adobe, Java, Open Office. As soon as I have internet at my house a few weeks ago, I started to update everything. My computer (HP Pavilion, Pentium 4 of 2006 - old, I know) now seems to work very well, but it's very annoying that everytime I open Firefox, I get a new tab page I ask, in addition to my homepage of Mozilla. Even more annoying is that my computer automatically to this page of the new tab. I tried to disable the new tab page by following the instructions given through the Mozilla 'Getting Started' page, rebooted the computer, and nothing has changed. Please advise!

  • How can I limit the number of Web sites on the new tab page?

    Is there a setting where I can limit the number of thumbnails / Web sites that appear on the new tab page? When I opened a new tab - I don't want to see tons of sites I have visited - but also, I don't want to delete them all. For example - there is a setting where the new tab page displays the last ten sites I've visited - with all my pinned sites?

    There are two settings 'hidden' for this 'grid '.

    Browser.newtabpage.Columns

    and

    Browser.newtabpage.Rows

    Type of topic: config in the URL bar and press ENTER.

    So put . browser.newtabpage in the top search bar.

    Each of these preferences in the lower panel right-click and select Edit. Then change the value default of 3 for each of these preferences to what you prefer, for "pinned" both sites all browsing history you want to appear in the 'grid '.
