  • RT-20372 said backspace does not work for TextField, but if you open the new window it works

    Hello

    See this bug (registration required) = "TextField doesn't consume backspace and delete key events.

    I use this

    • Win 7/64-bit
    • last 7 + updates java to update
    • Kepler Eclipse + efxclipse

    I'm a developer of this application from https://github.com/Johnmalc/BankApp , I encountered the problem that shouldn't work. For me it works and I don't know why?

    The said bug that backspace does NOT work in the textfield. But in my case If I open a new window (concert at the scene) and then back in the new window works fine. This is my example of this controller class that is responsible for such behavior.

    class Controller {
@FXML
    private TextField AccountNumberField;
.......

@FXML
    void initialize() {
AccountNumberMethod();
.........
}
@FXML
    void AccountNumberMethod() {
        AccountNumberField.addEventFilter(KeyEvent.KEY_PRESSED, new EventHandler<KeyEvent>() {

                    @Override
                    public void handle(KeyEvent event) {
                        if (event.getCode() == KeyCode.ENTER) {
                            int AccountNumber = Integer.parseInt(AccountNumberField.getText());
                            ac.setAccountNumber(AccountNumber);
                        }
                    }
                });
    }
}

    And it is the class where I call class Conroller

    @FXML
     void NewAccount() {
          NewAccount.setOnAction(new EventHandler<ActionEvent>() { //NewAccount is button

               @Override
               public void handle(ActionEvent event) {
                    Parent root;
                    try {
                         root = FXMLLoader.load(getClass().getResource("/res/account.fxml"));
                         Stage stage = new Stage();
                         stage.setScene(new Scene(new Group(root)));
                         stage.show();
                    } catch (IOException e) {
                         System.out.println("error");
                    }
                    event.consume();
               }
          });
     }

    So my question: which is on purpose or it is a bug that should be reported.

    You can also see my 3 files of the application here https://github.com/Johnmalc/BankApp/tree/master/src/application

    I have prepared a file zip-eclipse-so you can download it and help me as soon as possible.

    Thank you. Ask me more if needed.

    @malcjohn

    Well, that said, in your controller, you event filters that consume all events events KEY_PRESSED on text fields. So it is little surprise that the text field does not have to receive some key events. It is not at all clear to me why you did it; These event filters treat only enter anyway, so why not simply manipulate the ACTION_EVENT on these controls. (If I understand it, the key events that generate text characters are managed by listeners for KEY_TYPED text fields, while for non-text characters key events are handled by event listeners KEY_PRESSED. Which is why you normally receive the regular keys.)

    Your event management is extremely complicated anyway. You register methods in the FXML to manage events, but the methods themselves define the event handler, instead of having just the event handling code. Then, you call these methods manually from the method initialize anyway. You seem to have yourself confused about management of the events of JavaFX. You probably want to read the tutorial that explains how to manage the events just by using the code Java and then read the section "add rows to the table" in the FXML tutorial to see how to save FXML event handlers. You currently have some weird hybrid of the two techniques, which is not what you think it does.

  • Android, backspace does not work in a flash.text.TextField

    Hello

    I have a bug on my Nexus 5 Android 4.4 Air 4.0.

    When I scroll the text in the textfield and I select the text (in my example almost word "subclass"), the textfield getting developed, if I put on the BACKSPACE, the deleted character is the previous character the first time, and if I put again on the BACKSPACE key, the deleted character is the first character and not the previous character.

You can give a text field an instance name in the Property inspector and use the methods and properties of the TextField class to manipulate it with ActionScript. TextField instance names are displayed in the Movie Explorer and in the Insert Target Path dialog box in the Actions panel.\nTo create a text field dynamically, use the TextField() constructor.\n\nThe methods of the TextField class let you set, select, and manipulate text in a dynamic or input text field that you create during authoring or at runtime.\n\nActionScript provides several ways to format your text at runtime. The TextFormat class lets you set character and paragraph formatting for TextField objects. You can apply Cascading Style Sheets (CSS) styles to text fields by using the TextField.styleSheet property and the StyleSheet class. You can use CSS to style built-in HTML tags, define new formatting tags, or apply styles. You can assign HTML formatted text, which optionally uses CSS styles, directly to a text field. HTML text that you assign to a text field can contain embedded media (movie clips, SWF files, GIF files, PNG files, and JPEG files).

  • The internal keyboard BACKSPACE key does not work

    I have a laptop Toshiba Satellite and the BACKSPACE key does not work.

    He will start work the rare opportunity, but then it just stops working again.
    This happens on everything, including word and internet ect.

    It has been like that for a few weeks now and I turned the laptop and turn off many times.
    Is there a way to fix it myself or I send for repair?

    Please, * don't * tell me:
    Get an external keyboard
    Try it turn on and off
    Just highlight the words and use the delete key - it's annoying to have to do this all the time
    Type carefully and do not make so many mistakes

    Thank you!

    > Please, don't tell me not to:
    > Get an external keyboard

    And why shouldn't t someone recommends you to check the functionality using the external keyboard?

    It s recommended to connect an external keyboard to verify how the BACKSPACE key would work using 2nd external keyboard. In case the back might work properly using USB keyboard, the question is very clear; in such cases its main shortcomings. The key cannot be replaced or changed or fixed. In this case, need to replace the entire keyboard!

    In case the BACKSPACE key does not even using the external keyboard, then this would mean that the internal keyboard controller is faulty and in this case only the replacement motherboard would be useful.

    But to be honest, I think that its simple keyboard failure and a replacement would solve this.

  • the Pencil Eraser backspace delete strokes does not work in script

    I came up against a little problem this tutorial:

    I can't erase my lines, now, I have a little more then just a pencil and a bit of hole menu,

    now, I even download the file and in the file it does not work either

    I use flash cs4...

    now, I don't want to do something complex like actionscript 3

    but always a solution and if it is not hard to do an eraser to?

    + I do not have a solid background of Pentecost.

    Thank you

    There is no easy way to create a dynamic gum if you do not have a solid background.  you will need to use the bitmapdata class and this is a task for advanced actionscript coders.

  • BACKSPACE key does not work in DW (OSX)

    In Dreamweaver, when you select a local file and press the DELETE key (delete back located between the slash and the end key), nothing happens. In the context menu, there is a clear symbol of key but nothing happens.

    Someone at - it why the Clear button does not work?
    I use OS X 10.6. But I could remember what happens in older operating system.

    Thank you

    After the restoration of the preference of keyboard shortcuts, press command-delete seems to work.

    I went to another framework and devulcanization back to the game from Macromedia. This seems to have reset the setting.

    Hello

    (1) once the unit is on keep tap the F8 key, select the last good known configuration & check if Unit works very well.

    (2) you can also try F10 key try to do a Bios default.

    (3) once the unit is power on keep touching the use key F8, and then select Safe mode with command prompt type keys and check if the keys does not work, you may need to replace the keyboard because it is a hardware failure.

  • CTRL key does not work as expected

    Original title: keyboard Help!
     
    There is a recurring issue going on with my keyboard or very probably my pc...
    Well first to start with - I use a software type "ventrilo" called "mumble" that uses the 'CTRL' key as a key to talk with others in the same precedente.* *-could be a reason
    My CTRL key seems really screw randomly until that moment, it turn on sticky keys [where ctrl has practically been pressed permanently] even if it is not enabled on the settings... which makes it really difficult to browse web site or use games because I'm unable to type.
    Even if I try to disable it by using the two keys ctrl - it does not turn off...
    When I try to copy and paste using my CTRL key left it appears just under the letter c or v when I'm trying to do, but when I do it with my right ctrl - it is successful...
    * steam question *.
    I use also a program called "steam" that allows me to talk with others and play some games - but the sticky keys seem to be really stuck on this issue, I am unable to do anything...
    Whenever I press 'a' after that it is already used once - it will remove 2 characters: example: I type AGT-> and I press 'a' once more-> deletions G and T
    or whenever I have press BACKSPACE at all during a conversation of steam, it deletes everything.
    Urgent W on it also a tab or an im window closed on...
    pressing V will paste what I had copied at all, and finally pressing z would substitute a letter - for example: za-> type z once more-> towers to zz
    I hope you understand what I'm talking... help? Thank you...

    Hello Kent,

    Let us make sure that this isn't a keyboard problem. Connect a different keyboard to see if the CTRL key is working.  If it works fine, then it is a problem of faulty device. You may need to replace the driver.

    If this does not work on the new keyboard, then it must be a setting in the software that you have installed that is causing this problem.

    As a work around, I suggest to uninstall and reinstall the drivers for the keyboard and check if this solves this problem.

    1. type of Device Manager in the Start Search box and press on enter.

    2. browse the keyboard.

    3. right click on the mentioned keyboard driver and select Uninstall.

    4. once the driver is uninstalled, restart the computer and check if the problem persists.

    Note: Windows will automatically detect the keyboard and install the necessary driver via Windows updates.

    See 't-working-properly#update-driver-hardware-isn't-working-properly=windows-7 http://windows.microsoft.com/en-in/windows/update-driver-hardware-isn

    If the keyboard print incorrect characters, then try the steps mentioned in http://support.microsoft.com/kb/258826
