Position of the cursor Set for TextInput

Does anyone know of a method that I can call on TextInput focus to define the position of the cursor or select certain passages in the input field? I try to get the cursor always start typing at the end of the pre-populated text.

I tried these, but they do not seem to be valid methods for TextInput (I wasn't expecting to work because they are not in the documentation, but worth the try):

mytxtInput.setSelection(mytxtInput.text.length, mytxtInput.text.length);

OR

mytxtInput.selectRange(mytxtInput.text.length, mytxtInput.text.length)

Any help would be greatly appreciated!

Thank you to all members of this forum for everything that they great posts! They have really helped answer many of my questions.

Hey,.

you have the right idea, but instead to apply the method setSelection on your TextInput object, you must apply to the internal textField property reference to the textfield inside.

Here is a code example of an old NET that selects all of the text into a TextInput object:

package{   import flash.display.Sprite;  import flash.display.StageAlign;  import flash.display.StageScaleMode;  import flash.events.FocusEvent;   import flash.events.MouseEvent;

  import qnx.ui.buttons.LabelButton;    import qnx.ui.text.TextInput;

  [SWF(width="1024",height="600",backgroundColor="#CCCCCC",frameRate="30")] public class TextInputTest extends Sprite {

       private var myInput:TextInput;

      public function TextInputTest()       {         super();

          // support autoOrients            stage.align = StageAlign.TOP_LEFT;            stage.scaleMode = StageScaleMode.NO_SCALE;

          myInput = new TextInput();            myInput.setSize(300,50);

          addChild(myInput);          

          var newBtn:LabelButton = new LabelButton();           newBtn.label = "Click Me";            newBtn.setPosition(325, 0);

          newBtn.addEventListener(MouseEvent.CLICK, selectMyText);

          addChild(newBtn);

      }     private function selectMyText(e:MouseEvent):void      {         stage.focus = myInput;            myInput.textField.setSelection(0, myInput.textField.length);      } }}

This line is where it does the trick:

myInput.textField.setSelection(0, myInput.textField.length);

the first parameter is the selection of the starting points and the last parameter is how much it should be chosen.

Here is the link to the thread that the code comes for more details:

  • Set the position of the cursor in the text added (to make the part of the text in index) in WORD using Report Generation Toolkit

    I would like to generate a report in WORD using the report generation toolkit.

    Whenever a text is added to the report, the program should put part of the text index. The problem I am facing with is to set the cursor position in the current location of the text.

    Any suggestions?

    Hello!
    I think that's what you wanted (see attachment).

    First, you must set position for each loop, so after adding the table, your cursor index need to increase the number of added characters. That's why I have included the text of the report, Append - to get the position of the cursor at the end.

    Indexing begins with 0, so you need to set the 3 and 7.

    Hope you get what I mean

    Hello

    I have a problem to find the position of the cursor in a field inputText component.

    ... had the chance to look at the source code of the sample. ADF Faces renders text as HTMLTextArea fields when the value of the rows property. The JavaScript code used in the example of client works differently for FF and IE if the input is a text box. This could be a problem in IE or just used JavaScript code. The rows back to a single line (remove) property makes the text as HTML input feldworking with the JavaScript for IE and FF.

  • Set the Position of the cursor in the Console (console or Windows default or CVI) window

    Hi all

    I'm working on a project for my college class with a large amount of data acquisition. Unfortunately, the part of the assignment asks to do entirely in the console rather than through a User Interface.

    I've programmed in C++ and have used the command gotoxy(). However, this is not part of the ANSI C standard. I can't find any additional information about the position of the cursor in C or CVI standards. Is it possible to position the cursor in CVI? If I have to, I'll resort to create a matrix of character as a screen buffer and encode them manually.

    Thanks again!

    CVI 8.5

    These functions are part of the windows kernel. simply #include . If you get a link error, these functions should be in 'kernel32.lib' comes with LabWindows/CVI: Add kernel32.lib to the project and everything should be good (search folder x:\Program NIUninstaller Instruments\ to locate, its complete location depends on the version of the CVI you use).

    of course, this means that you must install the Windows SDK: it is an option in the installer of LabWindows/CVI. (you can also download the Windows SDK from the microsoft Web site, but you would be better with one that comes with CVI).

    a short guide on the documentation for the Windows SDK: each function is documented in a single page on every page of documentation for function, there is always a short summary at the end of the page telling you how to use the function: which header file you include, what library file, you must link with and on what version of Windows , the function is supported. Unfortunately, until the CVI 8.5.1 (I don't know for the CVI 9.0), the documentation for the SDK does not include the table of contents, which prevents to find something useful, unless you know what you are looking for the function.

  • Flex TextInput to get the current position of the cursor

    TextInput component in how to get the current position of the cursor? Because I want to record a loss of focus on the location of TextInput dynamically add text.

    Here:RichEditableText is a part of the skin of the class spark TextInput and is what is doing all the text in the editing/rendering of work. If you need to make all text advanced operations, they need to go through the property here. Because it is a part of the skin, you need to make sure that is not null before doing anything on this subject.

  • How can I change the language setting for 4500 WANT after the initial Setup

    The language setting for the ENVY 4500 e-all-in-one printer has been mistakenly or inadvertently put in CHINESE (not sure how this can happen).  Now, the display is incomprehensible, so I can not understand how to change the language to ENGLISH.  Is there a simple way to change the language or reset the printer by default so that I can fix this problem?

    Thank you.

    Hi scfessler,

    Welcome to the HP Forums.

    I see you have a problem with the printer displayed in another language.

    On the front screen of the printer, press the top left button ( Home button).  Once on the home screen, press the arrow UP 2 times, this brings you to the preferences Menu, press OK.  Once in the Preferences menu, the first highlighted area is the enacted area please just press OK again.  The first language highlight is English, please press OK and then Yes to make the changes.

    If you still have questions, please let me know.

    Thanks for your time.

    See you soon,.

  • How to add text to the position of the cursor in HTMLEditor in JavaFX

    I know how to add new button to HTMLEditor and I want all of my action button to paste text at the current position of the cursor.


    //HTMLEditor html;
    //String IMAGE_URL = "http://...";
    Node node = html.lookup(".top-toolbar");
    if (node instanceof ToolBar) {
           ToolBar bar = (ToolBar) node;
           ImageView graphic = new ImageView(new Image(IMAGE_URL, 32, 32, true, true));
           Button myButton = new Button("", graphic);
      bar    .getItems().add(myButton);
      myButton    .setOnAction(new EventHandler<ActionEvent>() {
           @Override
           public void handle(ActionEvent arg0) {
           //needs code
           }
           });
    }

    Use the webkit API, so this isn't something you want to use in production since there is no guarantee that JavaFX will use webkit in the future. Really, the HTMLEditor should have an API editor that makes all of this transparent.

    You will need to import javafx.scene.web.WebView, com.sun.javafx.webkit.Accessor, and com.sun.webkit.WebPage;

                myButton.setOnAction(new EventHandler() {
                @Override
                public void handle(ActionEvent arg0) {
                    WebView webView = (WebView)htmlEditor.lookup("WebView");
                    WebPage webPage = Accessor.getPageFor(webView.getEngine());
                    webPage.executeCommand("insertText", " World Cup Soccer ");
                }

  • What is the best setting for H264 Blu Ray bit rate, which will play OK on most / all blu ray players.

    What is the best setting for H264 Blu Ray bit rate, which will play OK on most / all blu ray players. When you use CBR and VBR. What are the benefits of progressive and interlaced with regard to playback on all players.

    You don't need to worry about compatibility with Blu - ray playback.

    I prefer a variable bitrate for its effectiveness.  (Not necessary spending 25 MB on a framework in need of 10 right?)

    Using interlaced or progressive will depend on what you shot.  (Take note that 30 p is an atypical, so do not pull that.  Pull only 720 p/24, 720 p/60, 1080 p/24 or 1080i/30).

  • DPS: Judge to use the parameter Raster or vector in the States of the objects when the majority of the page is a photo. What is the best setting for the overall performance?

    I am trying to decide whether to use the parameter Raster or vector in the States of the object when the majority of the screen is a picture (with a modest but important legend for children to read). The legend certainly makes it look more net as vector. But does the photo! The raster setting seems to make the lower-res images in comparison. In my first edition of my application, I thought that raster would be the best setting when the photo was the subject dominating the page. But now, after seeing how strong he looks like vector, (but with almost a refresh of the unacceptable time. Perhaps better on the latest iPad. Most of my readers/students in class will use iPad 2 s, which has a slower processor). I wonder if I should go through the trouble of changing States of photo objects that have the type as well to the vector. It doesn't seem to be as sensitive to a re - draw on the iPad 2 (non-retine)

    Is Filesize hit if I make about 1200 on these objects range from Raster to vector? (It is a huge, highly interactive history book, so I'm curious if acutally go to vector on these photos would reduce the size of the file) What is the best setting for the overall performance?

    I see the freeks screen outside for a bit if you try to pinch and zoom in a vector object (photo) vs raster. Which is disappointing. Does slow down load time/refreshment in frame, which is a little less. I also found that the drop shadows really bad that redraws effect in vector, almost vibrating in a slide show, for example. Thus, in cases where I need shadows, I'm sticking with Raster.

    All tips go ahead?

    then with Canopus HQ, even of quality but a little more light (6 GB),

    I tried with all settings and codecs, but I have not found what I want.
