How to control the cursor position on a text item..

Hello,
How can we control the cursor position programmatically on a text item.
i.e. how do we move the cursor to home or end of the text item.
TIA,
Hiten

  • Controling the cursor position

    Hi all,
    I have two x, and y signal outputs from a dll module and I plan to use them to control the cursor position. One problem I'm facing is that my signals are variable enough to cause the cursor to vibrate in stationary setting. So, I use hysterysis (putting threshold) to eliminate these fluctuations but the drawback is that keeping the treshold high enough to eliminate the fluctuations keeps me from getting a nice, smooth movement when the speed of movement (rate of x and y changing) is low. Any ideas or suggestions will be appreciated.
    p.s. I am using "SetCursorPos".dll as you might have already guessed.
    Thank you,

    The formula for an exponential filter of degree D is the following:
    New Average = (New Value + (D-1)*Old Average)/D
    I usually add a special case for startup so that D is never greater than the number of points. 
    As I said, it is a low-pass filter, much like using a running average.  I usually like it because the state is simply a single value (Old Average) instead of the array of values you have to keep around to do a running average.
    As to the new question of separating high-frequency noise from your high-frequency signal, that is a bit more complicated (obviously).  You should take a power spectrum of the noise to see if there is a characteristic feature you can use (cutoff frequency, strong peaks).

  • How to get the cursor position on a picture?

    I'd like to show the cursor position on a picture
    which is 400 by 400 pixel size and located at
    (0, 0, 400, 400) on a panel. So suppose that the
    cursor is at (50, 50), how can the java code know?
    Thank you.

    I am thinking about this, and use something like

  • Can I control the cursor position

    I'd like to confine the cursors position to a grid when it's within a particular panel. I tried public void mouseMoved(MouseEvent e)
    int x = (int) (GRIDSIZE*java.lang.Math.round(e.getX()/(1.0*GRIDSIZE)));
    int y = (int) (GRIDSIZE*java.lang.Math.round(e.getY()/(1.0*GRIDSIZE)));
    e.translatePoint(x,y);
    } But that didn't work. Can it be done?

    I'm not exactly sure what you want to be done, but, if you want to control the mouse position, you can create a Robot object (check the class in the java docs) and use robot.mouseMove(mouseX,mouseY) where mouseX and mouseY are integers. THIS ONLY WORKS IN APPLICATIONS THOUGH. its too powerful to be able to control a persons mouse, (and keyboard is controllable too with Robot), you can imageine what a person could do lol.. Anyway, you could repeatedly check if the mouse position is on the grid, and if it isn't, use robot.mouseMove, to place it onto the grid.

  • How to enter the data into data block text item which has an LOV associated

    Hi,
    I have a data block, one of the data block text item has an LOV assigned. when I populate this text item using the LOV and do "execute_query", it is taking the value in the text item and adding it to the search criteria, but when I enter a value manually in that text item and do "execute_query" it is showing me an alert(which I created) "Please enter a value".
    My question is, why is not taking the value that I enter manually? Looks like before executing the query, this field is getting empty
    How to avoid this problem and make sure that the value entered in the text item is added in the where clause of the query?
    Any advice?
    Thanks in advance
    R.G

    Problem solved!
    Before doing execute-query, all the text items are being cleared,so I used a global variable to store that value
    Thanks anyway

  • How to change the default position of context menu item? (C#)

    Hi,
    I have included a calendar context menu item with my Outlook Addin. But by default, its positioned at the last as shown in the picture below:
    I need a way to make it as the fourth item instead of last one. Also, I want set an icon for the same. How can I do that?
    Appreciate if you can give some sample examples.
    Thanks in advance.
    Thanks Prasad

    Hello Prasad,
    The
    Customizing Context Menus in Office 2010 article in MSDN describes the basics.
    You can specify the IdMso value of the built-in control after/before you need to insert your own:
    <button id="MyBtn" label="MyButton" insertBeforeMso="OpenSelectedItems" />
    See
    Office 2013 Help Files: Office Fluent User Interface Control Identifiers 
    for IdMso values.

  • Locating the cursor position

    Is it possible to locate the cursor position in a text item? in other words can I find the number of characters to the left of the cursor in a text item?
    I really appreciate any kind of input on this.
    null

    I have to insert user selected variables that show up in a LOV into the text item at the cursor position.
    A sloppy workaround for this problem is asking the user to put in a pre defined symbol where ever he/she wants to insert the variables and then replace the variable with the value selected from the LOV using the REPLACE function. There is always a chance of error here!
    Instead if there is a way to know the cursor position, like the no. of characters to the left of the cursor or the cursor co-ordinates.............

  • Photoshop CS5 - Control and navigate the cursor position automatically

    Hello
    I wonder if it’s possible with Photoshop CS5 (OS: Win7)  to control and navigate the cursor position automatically?
    Given: I have individual image coordinates for a set of locations.
    Wanted: A possibility to position the cursor sequentially at those image location by the means of an external script or procedure.
    Any ideas if that is possible with CS5?
    Thanks for any help.
    Lars

    As far as I can tell with regard to a Photoshop Scripting approach: No.
    Creating a Selection of certain dimensions and a certain position would be possible, though.
    What exactly are you trying to achieve?

  • Is it possible to control the cursor of a XY-graph via Keyboard and read the y value of the curser x-position?

    I have following problem when I control the cursor via an attribute note, it is neccersary to free the cursor, but then it is not possible to read the y-Value of the cursor position. I want to control the cursor via keyboard and buttons, but with the funtionality of attribute setting "cursor fixed to plot".

    You know the X position so just read the Y value by reading it straight from the Y array instead of from a property node...
    Alternatively unlock the cursor if the position control has changed...and lock it again if it is constant for n milliseconds; to produce the Y value from the Y property.

  • Changing the cursor position

    Is it possible to change the cursor position automatically when changing the language?
    For example: when changing from English to Hebrew the cursor will move from the right end to the left?
    Thanks,
    Amnon

    I don't think this is possible in general, although some individual apps might do it.  Normally you use a direction control from an app menu or at the system level.

  • Is there a way to get the cursor position index of html text field

    I'm trying to work on a text pad like MC with "insert text at
    position X" and "find and replace" can anyone tell me how to find
    the cursor index of an html text field. Selection.getBeginIndex() ,
    Selection.getEndIndex(), Selection.getCaretIndex() as far as I know
    these methods only work with text and not htmltext.
    What I'm trying to do is assign different parts of the string
    to variables so that I can combine them to reconstitute my html
    string.

    enfantterrible:
    If I understand correctly, you want the corresponding
    position in the
    htmlText propery of the caret index (which as you point out
    is only the
    position in the plain text version of the textfield content).
    Below is how I would do it. Maybe there's an easier or more
    efficient
    way (using XML objects etc), but I don't know it. You could
    conduct all
    your string searches in the plain text and then convert the
    result to
    the html positions. I didn't build this to accept negative
    parameters
    for the pos parameter (e.g. from end of string backwards) but
    the
    function could be adapted to do this too if necessary. The
    test data is
    not proper html from a text field, but it doesn't really
    matter what it
    is so long as its formatted correctly. It just separates the
    tags from
    the content to enable apples with apples comparison.
    //some test data
    var testStringXML = "<format>Hel<b>lo i can't
    t<i>ell you h</i>ow hap</b>py I
    am.</format>";
    var undecoratedString = "Hello i can't tell you how happy I
    am.";
    //the conversion function
    function findDecoratedPosition(pos:Number, xmlString:String,
    test:Boolean):Number {
    //anything between '<' and '>' should be excluded from
    plain text search.
    //create an array of array elements (n=2) consisting of tag
    then plain text
    //requires correctly formatted xml/html
    var tempArr:Array = xmlString.split("<");
    for (var aa = 0; aa<tempArr.length; aa++) {
    tempArr[aa] = tempArr[aa].split(">");
    //remove the first and last elements of the new array (these
    are empty)
    tempArr.pop();
    tempArr.shift();
    //find the corresponding plaintext location and calculate
    the "decorated" position
    var retPos:Number = 0;
    var posCount:Number = 0;
    for (var aa = 0; aa<tempArr.length; aa++) {
    retPos += tempArr[aa][0].length+2+tempArr[aa][1].length;
    //+2 allows for missing < and >
    posCount += tempArr[aa][1].length;
    if (posCount>pos) {
    return (retPos+(pos-posCount));
    //out of range
    return -1;
    //test code:
    for (var aa = 0; aa<undecoratedString.length; aa++) {
    var altPos = findDecoratedPosition(aa, testStringXML);
    trace(undecoratedString.charAt(aa)+" in position "+aa+"
    plainText equates to position "+altPos+" in the decorated version
    ["+testStringXML.charAt(altPos)+"]");
    }
