• Position of the caret in JEditorPane HTML

  Hello world
  I need the position of the caret in the HTML source on JEditorPane. I have
  The value of getCaretPosition() is not what I wanted. CaretEvent.getDot () gives the same value of getCaretPosition. These methods only gets position on the view.
  Help, please! Thank you very much!

  It is not possible. HTMLParser creates the structure of the Document (tree of items) of html text, but it has nothing to do with the content.
  Position in the html source is not correct because it can hold to support the space between the labels or tab characters or \n tanks that are ignored.

• AF:inputtext change the color of the text on pressure from button and the position of the caret

  Hi all

  Very green, when it comes to ADF so I hope to give you enough information to get assistance.

  I found a 2008 document that created Frank Nimphius that shows how the JavaScript in the ADF and the manipulation of the inline style property.

  It is titled "ADF Code corner 010. How to create a character counter of entry for text fields.

  While my use case is not the same I feel that I could use for my use case logic.

  My use case is that the user wants a text field to replace the blue color when being typed in so that they know what they changed.

  I'm jusing JDeveloper 12.1.2

  That's what I have my input text looks like:

  <af:column sortProperty="#{bindings.ChiefScaleOrderVO.hints.OrderNo.name}" filterable="true"
                                 sortable="true" headerText="#{bindings.ChiefScaleOrderVO.hints.OrderNo.label}" id="c1"
                                 width="11%" inlineStyle="#{recordManager.columnStyle}">
                        <af:inputText value="#{row.bindings.OrderNo.inputValue}"
                                      label="#{bindings.ChiefScaleOrderVO.hints.OrderNo.label}"
                                      columns="#{bindings.ChiefScaleOrderVO.hints.OrderNo.displayWidth}"
                                      maximumLength="#{bindings.ChiefScaleOrderVO.hints.OrderNo.precision}"
                                      shortDesc="#{bindings.ChiefScaleOrderVO.hints.OrderNo.tooltip}" id="it1"
                                      autoSubmit="true" valueChangeListener="#{recordManager.columnTextModified}"
                                      clientComponent="true">
                          <af:clientListener method="keyInput" type="keyPress"/>
                          <f:validator binding="#{row.bindings.OrderNo.validator}"/>
                        </af:inputText>
                      </af:column>
  

  This is what looks like my javascript:

  <af:resource type="javascript">
         function keyInput(evt){
            //document.getElementById(evt.getSource().getClientId() + '::content').style.color = 'blue';
            textfield = evt.getCurrentTarget();
            textfield.setInlineStyleProperty("color","blue");
         }
  </af:resource>
  
  

  If I do an alert (textfield.getInlineStyleProperty("color")); before and after the the setInlineStyleProperty it does not say it gets the value at the blue, but my text color never changes.

  If I do the document.getElementById (evt.getSource () .getClientId () + ': content ""). style.color = "blue"; It works, but I'm doing things the "right way".

  So is there another way to do this now in 12 JDeveloper?

  Also is there anyway to when you click inside an af:inputText that he will not select all of the text and just position the cursor at the end?

  Thank you

  Derek Hansen

  Well, you try to set the wrong property.

  According to your example of "pure" javascript, you must set contentStyle and not inlineStyle.

  Then try something like: textfield.setContentStyle ("color: Blue");

• TextField affecting the caret at the end when losing point on

  Hey everybody,
  
  I would like to put the caret of a TextField at the end of the text when the textfield loses focus, so that the last part of the name of the file will be shwon and not the first part. I ve tried the following:

  ChangeListener<Boolean> onLooseFocus = new ChangeListener<Boolean>() 
           { 
                @Override
                public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) 
                {
                     if (!newValue.booleanValue()) 
                     {
                          textFieldDateiname.end();     
                                  System.out.println(textFieldDateiname.getCaretPosition()); 
                                  // At this point the caret is at the end and it will show:
                                  //ReadOnlyIntegerProperty [bean: TextField[id=textFieldDateiname, styleClass=text-input text-field], name: caretPosition, value: 76]
                     }
                }
           };

  This ChangeListener is added to the focusedProperty() of my TextField method

  textFieldDateiname.focusedProperty().addListener(onLooseFocus);

  It not work doesn´t, the circumflex is temporarily at the end of the text field.
  
  Another question: if it works, I would like to reuse the ChangeListener onLooseFocus for diefferent TextField. So I would like to know which TextField has lost focus. I tried

  observable.getSoruce(); // like it works with keyEvent
  System.out.println(observable); // -> ReadOnlyBooleanProperty [bean: TextField[id=textFieldDateiname, styleClass=text-input text-field], name: focused, value: false]

  If the id of the source of the ChangeEvent is known...
  
  Any ideas?
  
  Thank you

  For the latter, you can climb the Observable to a ReadOnlyProperty and call getBean() on it; mount the getBean() call results in a TextField.

  I have no good solution for most of your question. It seems that the default behavior is to restore the position of carat at the beginning of the text, and the listener realizes that runs after your custom listener.
  If the best hack I see is to have a flag that replaces the carat position changes. Set the flag to true on loses focus. Register a listener with the position property of carat, and if the flag is set back to carat at the end (and then disabled the indicator).
  If you want to use the headphones on several fields of text, instead of a flag, have a set of textfields which will have their positions carat substituted changes.

  It's really a hack; I'd like to think that there is a better solution.

• Problem to find the Position of the cursor by using Java Script for an input TextField

  Hello
  
  I have a problem to find the position of the cursor in a field inputText component.
  
  The following code of java script to achieve. The same functionality works fine if I run in a simple html page. But when it is used the same javascript inside the jsff does not the position of the cursor.
  

  var adfComponent = AdfPage.PAGE.findComponentByAbsoluteId("r1:1:it3");
  var adfComponentClientId = adfComponent.getClientId();
  var div = document.getElementById(adfComponentClientId + '::content');
  div.focus();
  var docSelectionRange = document.selection.createRange();
  
  docSelectionRange.moveStart ('character', -div.value.length);
  
  var iCaretPos = docSelectionRange.text.length;
  
  alert("iCaretPos --> "+iCaretPos);  ---> This statement always returning '0'. Instead, i want the cursor position inside the text box.

  Please let me know what I'm missing.
  
  For your reference, sending the sample page html that works fine with the same kind of code.
  

  <html>
   
   <body style="font-family: tahoma; font-size: 8pt;">
   
    <script language="JavaScript">
   
     /*
     **  Returns the caret (cursor) position of the specified text field.
     **  Return value range is 0-oField.length.
     */
     function doGetCaretPosition (oField) {
   
       var iCaretPos = 0;
            alert(oField);
       if (document.selection) { 
   
         // Set focus on the element
         oField.focus ();
   
         // To get cursor position, get empty selection range
         var oSel = document.selection.createRange ();
   
         // Move selection start to 0 position
         oSel.moveStart ('character', -oField.value.length);
   
         // The caret position is selection length
         iCaretPos = oSel.text.length;
       }
   
       // Firefox support
       else if (oField.selectionStart || oField.selectionStart == '0')
         iCaretPos = oField.selectionStart;
   
       // Return results
       return (iCaretPos);
     } 
    
   
   
    </script>
   
    <form name="blah">
   
     Text Field: <input type="text" name="nameEdit" value="">
     <input type="button" value="Get Caret" onClick="document.getElementById('where').value=doGetCaretPosition (document.forms[0].elements[0]);">

  ... 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.

• How can I cange positions of the toolbars?

  I reinstalled Firefox after my hard drive crashed and the position of the upper toolbar (open tabs) is higher than the bar of menus (?) and I prefer the tabs to be below the menu bar. In general, how to change the location of the bars.

  In addition, the dark background is difficult for me to see and would get back to lighter I had before. So, how to customize the background of the bar colors?

  Thank you.

  There is an add-on very full which can customize many aspects of the interface, called Classic theme restaurateur. You can install it from the site of modules here:

  https://addons.Mozilla.org/firefox/addon/classicthemerestorer/

  To change the settings, you can use the Options button for the extension on the page modules. Either:

  • CTRL + SHIFT + a
  • "3-bar" menu button (or tools) > Add-ons

  In the left column, click Extensions. Then on the right side, find classic theme restaurateur.

• 19.02 Firefox breaks the position of the background image.

  Hi, I have a jQuery plugin that worked well until I downloaded Firefox 19.02 now the Image slider does not work.

  More precisely the position of backgroundImage doesn't seem to work. Instead of each piece of the picture being selected using a specific and different up and left (x and is position on the Image) all the pieces are showing the top left corner! It worked well in the earlier version of Firefox and still work on the latest versions of Google Chrome, Safari and Opera.

  Appreciate any help you can offer.

  It's logical. If Math.abs (yPos) works, then yPos cannot be a string, and therefore cannot contain units.

• Position of the button close the tab tab

  Just updated to 17 of Firefox on my Windows 7 PC. The close tab buttons are now on the left side of the tab instead of the right side. How can I move them back on the right side? I can't find other help on this and tried to play with: config userchrome, but nothing is. I can change the color, add a button in the bar, but does not affect the positioning of the buttons close the tab on the tabs themselves.

  Help!

  You have the module / theme / userstyle installed that controls tab behavior? You can resolve this problem by restarting with disabled modules. You can also reset firefox who, most likely, your problem will be solved.

• Portege M780-106 - the mouse pointer position of the stylus trolling

  Question re Toshiba portege M780-106 touch screen laptop:
  We have a problem with the mouse, the position of the stylus trolling.

  This gap considerably increases the speed of the increase in movement of the stylus.
  As we had a task of monitoring with the stylus it is problematic.

  We run the task in Windows 7 using python 2.6 with mainly pygame library functions.
  Is there a way to disable the process that produces this discrepancy between stylus pointer and mouse?
