Does TextArea support smooth focus navigation?

Hi,
I need to be notified when the user try to loose focus on a TextArea component, in order to ensure that the entered text by the user is valid. Same as the InputVerifier in swing
I tried using setOnInputMethodTextChanged but It doesn't work. You can check the below example
import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.TextArea;
import javafx.scene.control.TextField;
import javafx.scene.input.InputMethodEvent;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class JFXTextAreaExample extends Application {
    public JFXTextAreaExample() {
    public static void main(String[] args) {
        launch(args);
    @Override
    public void start(Stage primaryStage) throws Exception {
        init(primaryStage);
        primaryStage.show();
    private void init(Stage primaryStage) {
        VBox root = new VBox();
        primaryStage.setScene(new Scene(root));
        TextField textField = new TextField("Text Field");
        TextArea textArea = new TextArea("Text Area");
        textArea.setOnInputMethodTextChanged(new EventHandler<InputMethodEvent>() {
               @Override
               public void handle(InputMethodEvent inputMethodEvent) {
                    System.out.println("Text changed");
        root.getChildren().add(0, textArea);
        root.getChildren().add(1, textField);
}Thanks

Thx for your answer
I used focusedProperty.addListener(...) on my text area and it is working fine
However I'm trying to use focusedProperty.addListener(...) on a HTML editor but it is not working.

public class CustomHTMLEditor extends Application {
    private final String HTML = "<html><body>TEXT</body></html>";
    public CustomHTMLEditor() {
    public static void main(String[] args) {
        launch(args);
    @Override
    public void start(Stage primaryStage) throws Exception {

        final TabPane tabPane = new TabPane();
        primaryStage.setScene(new Scene(tabPane));
        tabPane.setSide(Side.BOTTOM);
        Tab viewTab = new Tab();
        viewTab.setClosable(false);
        viewTab.setText("Renderer");
        viewTab.setContent(htmlEditor);
        tabPane.getTabs().add(0, viewTab);
        Tab htmlTab = new Tab();
        htmlTab.setClosable(false);
        htmlTab.setText("Editor");
        final TextArea textArea = new TextArea();
        textArea.onInputMethodTextChangedProperty();
        textArea.focusedProperty().addListener(new ChangeListener<Boolean>() {
                @Override
                public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
                    if (!newValue) {
                        htmlEditor.setHtmlText(textArea.getText());
        htmlEditor.focusedProperty().addListener(new ChangeListener<Boolean>() {
                @Override
                public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
                    if (!newValue) {
                        textArea.setText(htmlEditor.getHtmlText());
        htmlEditor.setHtmlText(HTML);
        textArea.setText(HTML);
        htmlTab.setContent(textArea);
        tabPane.getTabs().add(1, htmlTab);
}Thanks

  • The item Hierarchical Context Menu does not support pre-calculation

    Hello,
    Trying to download pre-calculated web templates via RepAgent, using the Hierarchical Context Menu feature within the template (populated via control query with Hierarchy) the system returned the following message upon file download:
    "The item Hierarchical Context Menu does not support pre-calculation"
    As a result the Hierarchical Context Menu is not displayed on the downloaded html-files. Navigation not possible.
    Could not find any constraints documented in the online help, at this point.
    Question: is there something missing on our setup or is this really out of scope for precalculation with navigation?
    Any other experiences on that or shall we open OSS-message?
    Best regards,
    Markus
    (We are on BW3.1)

    Hi,
    we have the same problem. Does anybody have any hint or workaround? Is there a solution for this in 3.5 or any upcoming version.
    Any input is appreciated.
    Thanks,

  • Your client does not support opening this list with windows explorer - related to multiple uploads?

    Hi folks -
    I've read through some threads regarding "Your client does not support opening this list with windows explorer" and it seems a lot of folks have a lot of solutions throughout the forum posts.  Is there anything official or semi-official regarding
    this? 
    I've tried a lot of the fixes including:
    checking to see if the WebClient service is on
    modifying so-and-so registry (I've since changed them back since they seem to have no effect)
    and changing various settings in Internet Options including making sure the site is in the Local intranet zone.
    I could live without this functionality but just recently my upload-multiple-files functionality in SharePoint 2010 has also gone away (red x instead of directory UI).  I wonder if it's related somehow and could give us a clue.
    If it helps I'm using various browsers but of the IE flavor 8 and 9 32-bit as the base for testing this.

    For SharePoint 2013 (so could apply to 2010 as well), my problem was that I was trying to "Open with Explorer"
    something that probably can't be opened with Explorer. In my case, I just wanted to open my team's Shared Documents with Explorer. I found that when I first log into SharePoint and view the page, I'm presented with those Shared Documents, but also other things
    as well.
    To get "Open with Explorer" to work, I must click "Shared Documents" under the Libraries heading on
    the left. Then, all the other stuff (Links, Getting Started, etc.) go away and I'm focused on my team's shared documents. From there, I can go up to the Library Tools section in the ribbon, choose the Library tab in the ribbon, and click Open with Explorer.
    Works like a champ on Windows 7 64-bit, running IE 9 32-bit.
    Unfortunately that's not what was going on in my case.  One obvious way to check is to see if other people or other computers can Open with Explorer.  In my case it was just this one machine on my desk that had the issue.

  • I need firefox 2 temporarily to use with a program that does not support version above 2.0 what do i do

  • Firefox does not run smooth while loading websites.

    Firefox does not work smoothly when it is loading any webpage. Specially, when I open new tabs and load new websites while it is still loading last website in other tab, the situation becomes worse. Main problems that occur are - page will not scroll, or scrolling hangs for a sec or so, works a little bit and it happens repeatedly, new tabs will open but not smoothly, website loading also gets affected in similar way. The dot that revolves on tabs while loading any webpage gets really annoying. It revolves intermittently. Imagine a car engine not starting, it starts, stops, starts, stops. That's what happens with Firefox. But once all webpages are completely loaded and scrolled 2 or 3 times from top to bottom of the page, then it is all good. All the problems occur when page is still loading in fore- or background in any or all of the tabs. I tried to run Firefox with all add-on and plugins disabled, tried to refresh Firefox from troubleshoot information. But nothing helps. I even uninstalled and reinstalled Firefox. I guess my laptop is not having memory issues. I am using Windows 7 x64 based system. RAM is 4 GB. All other software work well. Most importantly, Chrome has no such issues in comparison to Firefox. Also, when IDM (internet download manager) takes over some downloads, the Firefox hangs for few seconds. Please help.
    Thank you.

    You can try to disable hardware acceleration in Firefox.

  • Nokia E75 does not support sis files

    I've been trying to upgrade the Ovi maps on my E75, because navigation has kept me saying that I need to renew the license. I went to Nokia web site and found out that I need to upgrade Ovi maps in order to get the free navigation. I have a 202.12.01 firmware and I installed it once again when I had unsuccessfully tried to upgrade Ovi maps. I have Ovi maps v3.01 09wk44b01 (MW OpenGL LM MN) and Map version 0.1.24.114 (OpenBitLM 6.22.5). I've deleted all old maps and started to download new ones successfully over Nokia Ovi Suite. I've downloaded Nokia Ovi Suite and followed the instructions for downloading and installing the newest version of Ovi maps application (I suppose it must be newer than the one I have on now, because navigation still wants me to buy license, I guess it must be 3.03 or higher). I've tried it several times from the scratch, just to make sure I did it right. Of course I've also chosen the right E75 phone from the drop down menu and I downloaded the file nokia_maps_3.01_09wk44_b01_s60_3.2_lm_rom.sis. I double-clicked it and everything seems to be right, but when action on the phone should be required the installation guide says "Nokia E75 does not support sis files". From the sis file name I can only now see that I have this version already installed.
    Does this mean I can not use navigation for free on E75?
    Can anybody help me ASAP, because I need the navigation evey day very badly?

    I'v followed the directions of chanchan05 "Just uninstall the maps app, delete the folder and file I mentioned, then reboot your phone. Open the maps app, and it should recreate the qf file and cities folder in a version compatible to 3.03." on /t5/Maps-Navigation-and-GPS/Wasn-t-it-supposed-to-be-quot-Navigation-on-your-Nokia-Free/m-p/668305#M...
    Afterwards I installed the sis file you pointed me to and it worked. The maps on the phone were deleted, so I downloaded new ones over Nokia Ovi Suite and tried the navigation. Unfortunately it stills demands buying the licence for the navigation.
    I guess this is because the recommended sis file is v3.01 and not v3.03? Is that right?
    Any other solution?

  • Does firefox support or is there an extension for firefox that adds "internal" QoS?

    I would like to add QoS rules to firefox to fulfill a simulation such as the following:
    1. 200 kbytes/s down 20 kbytes/s up guaranteed for MLB.tv
    2. 150 kbytes/s down 10 kytpes/s up guaranteed for youtube.com
    3. All other web pages use the rest of the available bandwidth.
    Does firefox support such a feature or is there an extension out there that does? Thank you in advance.

    You can open the image file in Firefox via File > Open file or by dragging the file in a Firefox tab, possibly on empty space on the tab bar or the new tab (+) button.
    Then you can click the star on the Navigation Toolbar to bookmark the link if that is what you want to achieve.

  • Leopard does not support reading/writing to SD card via network?

    I have a Pixma MX700. I can read and write to SD cards using the card reader built into this machine ... IF I use Windows XP. Leopard will mount the card and allow me to view it contents but the minute I try to import a file to my iMac, I get error code 1401.
    I've been told by Canon support that the new MP Navigator EX driver for Leopard disables reading from the memory card over a network. They claim Leopard does not support this function and reading the posts from others having the same issue using different multi-function printers, this would appear to be a Leopard issue, not a Canon issue.
    Can anyone confirm this and/or offer a fix?
    Thanks!

  • Does Lightroom support camera tethering?

    I looked through the forum and could not find this.
    Does Lightroom allow digital camera capture by tethering the camera to a computer like Camera Control Pro for Nikon's and Kodaks Camera Manager?
    If it does, this most likely will be our new and great workflow. Currently when using both Nikons and Kodaks we have to use four (or more) separate software programs to capture the image, adjust the image (if necessary) crop & retouch the image, and upload it to our laboratory.
    Looking for the vida loca.

    If it matters, we too would like to see tethering improved, especially for Nikons.
    Nikon has stopped supporting their Capture (V 4.x) software. Capture wasn't the greatest package but it served a purpose as the front line, 'real time' camera to screen program. Capture does not support the newest NEFs found in the D80, (and others?)! The replacement, Capture NX, does not support tethered shooting or browsing for that matter. NX has some interesting ideas but no tethering, no browser, it is useless to us? Nikon's new Camera Control Pro downloads the pics from the camera to the computer but leaves them there... no further processing.
    We are forced to find another solution. There are not too many to choose from besides LR. Capture Pro is pretty dear, Bibble's capture, while slick, directly from camera to browser, it is not too stable or reliable! Sorry guys but we can not be rebooting / making excuses while the customer is waiting. I haven't found anything else for a Nikon.
    Our business really needs good tethering as we usually shoot with the customer in the studio expecting to take home some prints. Besides 'real time' viewing, which is a real plus with the customers, tethering also eliminates the steps, and time needed to stop shooting and download images to the computer. It also makes for a real smooth two person operation.
    So, I (we), hope the LR crew is working on a direct import for all raw formats. The LR tethering could use a speed boost. Just eliminating the third party capture software and extra file move would be a big help.
