How to get the global coordinates of the mouse of a scene?

Hi guys,.

I want to connect a node to the global coordinates of the mouse position. I tried several things, but not more than work as expected:

1. APPROACH 1: setting a property onMouseMoved to the scene:

----
scene.onMouseMovedProperty () .set (new EventHandler < MouseEvent > () {}
@Override
public void handle(MouseEvent me) {}
stepDropper.setTranslateX (me.getSceneX () + 20);
stepDropper.setTranslateY (me.getSceneY () + 20);
}
});
---

This seems to work very well, but when the mouse is on a control node things are stripped: the node stops moving (I guess it's because control node that consumes the event)



2. APPROACH 2: Adding a glass on top of the stage to listen because there onMouseMovedProperty() - this should prevent controls consume the event
The problem is that when I add a knot of Rectangle glassPane on top of the stage, each node below becomes inactive (do not respond to events). As I know the blockMouse property that used to be in JavaFX 1.3 went because each default node spread events. Why the senior (rectangle) node glassPane blocks for the underlying nodes mouse events?

Hello
controls using mouse events, as they spread the scene. You must register an event-filter event filters are called during the capture/tunneling, which precedes the propagation phase, so filters get the events before that any manager of may consume.

Just replace
scene.onMouseMovedProperty () .set (new EventHandler() {}

by
scene.addEventFilter (MouseEvent.MOUSE_MOVED, new EventHandler() {}

  • Anyone know how to get the mouse pointer visible on the extended screen?

    Well, I finally managed to work on a way to project my w4 iconia on my TV.  So grateful to a number of people in the community for me that far, but every step seems to bring his own fresh problem to enter.  so a few questions:

    1. anyone who manages to get the iconia w4 to duplicate rather than extend?

    2 - does anyone know how I can control the expanded view - I have a mouse plugged into my iconia so that I can flip through the window I want to show it on the extended screen but the mouse pointer does not appear as visible on the display (TV) extended although it does not work but the shooting blind is very frustrating - okay, if I watch a movie as soon as it runs on the extended screen it does not much you must handle but assuming I want to just browse the internet and project that onto the extended screen, so it's a big problem.

    My apologies if these are stupid questions, I'm not very technically savvy.

    TYIA

    This seems odd. I always change an extra-large pointer and traces of mouse long but have never had a problem with the HDMI screens like that.

    What is the brand and model of your TV please? Maybe someone can duplicate.

  • How to get the FileSystemTree coordinates selected item?

    Hi can we idea me in how to get the coordinates of the itwn selected in a FileSystemsTree?

    THX

    You should do something like this:

    var itemRenderer:DisplayObject = fileSystemTree.itemToItemRenderer (fileSystemTree.selectedItem) as DisplayObject;
    Contact information: Point = itemRenderer.parent.localToGlobal (new Point (itemRenderer.x, itemRenderer.y)) var;

    contact information is now an object point representing the coordinates of your itemRenderer in the global coordinate system.

  • How to get the value of a * Global * Application point of JS

    If we declare an element of the request, which is NOT a level of the page in question, how we get the value of this element in an Action dynamic JavaScript on a page?

    For example, we declare a "global" variable as an Application named DEFAULT_AJAX_SEPERATOR and set its value with a calculation of the claim "on the new Instance" a moment later, on a page of the application, we would like to get the value of DEFAULT_AJAX_SEPERATOR via JavaScript.

    Page* level syntax element...
    $v( 'DEFAULT_AJAX_SEPERATOR' );
    .. How does not work. I don't understand why it's like $v can only access the elements on the page. However, the APEX is clearly able to get these global values since, for example, they are available in PL/SQL blocks. Also, I know that it is on the session object, because I can see it when viewing the session.

    So... What is sauce secret for obtaining this value?

    Thank you

    -Joe

    Hello
    Use something like this in your javascript code.

    var appItemVal = "& DEFAULT_AJAX_SEPERATOR.";

    Thank you

  • How to get the current location in the event thread?

    Hello!

    Can U pls tell me how to get the location where the thread object, it is in method() execution of MenuItem. PLS, tell me-

    I also used the different thread for the getLocation() method. But I do not have the coords of geo location...

    PLS, suggest me-

    My code is as below:

        private MenuItem getGeoCodes=new MenuItem("Current Coords",100,1){
    
                                 public void run(){
                                     double[] coords=getLocationCoords();
                                     this.wait(12000);
                                     System.out.println("Latitude :"+coords[0]+" "+"Longitude:"+coords[1]);
                                 }
    
                     };
    
        private double[] getLocationCoords(){
            Criteria criteria = new Criteria();
            criteria.setHorizontalAccuracy(500);
            criteria.setVerticalAccuracy(500);
            LocationProvider locationProvider = LocationProvider.getInstance(criteria);
            Location location=null;
            new Thread(){
               public void run(){
                       locationProvider.getLocation(60);
               }
            }
            QualifiedCoordinates qualifiedCoordinates=location.getQualifiedCoordinates();
            double[] coords=new double[]{qualifiedCoordinates.getLatitude(),qualifiedCoordinates.getLongitude()}   ;
             return coords;
        }
    

    But I myself NullPointerException. Coordinates get successfully, if we run the location capability in different function, rather than the event thread.

    Please help me-

    In my opinion, which may be too complicate things a bit. I think he's trying to do is register a LocationListener with his object of LocationProvider. Callback methods, send a message to the UI event thread as follows (no need to spawn threads):

    UiApplication.getUiApplication().invokeLater( new Runnable() {
        public void run()
        {
            // This code will execute on the event thread
        }
    });
    

    EDIT: If your interval is short, you can consider implementing this executable as a class and store an instance in the front.

  • How to get the text formatting in the tables

    Dear experts and aid

    For my project, I import an RTF file and then read the data into 3 tables. It works fine when just using the contents of the string of paragraphs. However, the final script should be able to read and to replace the text formatted...
    Why use intermediate tables? Because otherwise I need to swap between two fm-documents (and you can be a part of the book).

    The imported file starts with a certain number of lines separated into two parts by a TAB ("designates a TAB in \x08 FM)
    [[Garneau, 1990 #12]]    »   [9]
    The good article can also be locally as text, e.g. [9]
    Then follow the same (or smaller) number of paragraphs with text formatted like this:
    [9]"D. Garneau, ed., National Language Support Reference Manual (national language Information Design Guide. Toronto, CDN: IBM National Language technical Centre, 1990.

    Is it possible to replace in the body of the function below the next song

      while(pgf.ObjectValid()) {
        pgfText = GetText (pgf, newDoc);
        gaBibliography.push(pgfText);
        pgf = pgf.NextPgfInFlow;
      }
    

    with this

      while(pgf.ObjectValid()) { 
        gaBibliography.push(pgf);
        pgf = pgf.NextPgfInFlow;
      }
    

    Do I need a special statement of the gaBibliography range?
    And how to get the right part of the lines as formatted intro thingy in table gaFmtCitsFmt ?

    Currently, I read in the tables as "strings" (function GetText not shown):

    var gaFmtCitsRaw  = [];                           // left column in processed RTF
    var gaFmtCitsFmt  = [];                           // right column in processed RTF
    var gaBibliography= [];                           // bibliography lines from processed RTF
    // filename is something like E:\_DDDprojects\FM+EN-escript\FM-testfiles\BibFM-collected-IEEE.rtf 
    
    function ReadFileRTF (fileName) {
      var nCits=0, nBib = 0, openParams, openReturnParams, newDoc, pgf, pgfText ;
      var TAB = String.fromCharCode(8);               // FM has wrong ASCI for TAB
      var parts = [];
      
      openParams = GetOpenDefaultParams();
      openReturnParams =  new PropVals();  
      newDoc = Open (fileName, openParams, openReturnParams);  
      pgf = newDoc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf;  // get first pgf in flow
    
    // --- read the temp/formatted citations  
      while(pgf.ObjectValid()) {
        pgfText = GetText (pgf, newDoc);
        if (pgfText.substring (0,2) == "[[") {        // citation lines start with [[
          parts = pgfText.split(TAB);                 // get the two parts of the line
          gaFmtCitsRaw.push (parts[0]);               // Push the result onto the global array
          gaFmtCitsFmt.push (parts[1]);
          pgf = pgf.NextPgfInFlow;
        } else { break }
      }
    
    // --- read the bibliography
      while(pgf.ObjectValid()) {                      // until end of doc
        pgfText = GetText (pgf, newDoc);
        gaBibliography.push(pgfText);
        pgf = pgf.NextPgfInFlow;
      }
      newDoc.Close (Constants.FF_CLOSE_MODIFIED);
    } // --- end ReadFileRTF
    

    The following questions will then be how to change the script of FindAndReplace of Ian Proudfoot for managing text formatted as replacement. I will need to use the copy and paste IMHO...

    Klaus, okay, before pasting, you must assign the TextSelection object at your insertion point.

    // Add a new paragraph after the current paragraph.
    var newPgf = oDoc.NewSeriesPgf (lastPgf);
    var textRange = new TextRange (new TextLoc (newPgf, 0), new TextLoc (newPgf, 0));
    
    oDoc.TextSelection = textRange;
    oDoc.Paste ();

  • How to get the text have the same effect as the video?

    Hello

    For the first time post here, but I wonder how to get the text of the titles have the same effect as the video behind her.

    For my video, I use 'bad tv' and other effects such as Gaussian that obviously changes the appearance of video, creating the look of VHS. However, I then inserted text via the title, but it normally appears. How can I make this text have the same effects as the video behind it?

    A friend told me I might need to add text to the video first, then do the effects, I have not tried, but wonder if there is an easier way, as this would require me to restart.

    EDIT: That's what I'm looking for. https://youtu.be/7_2PHQI89dI?t=24s The text has the same effect as the video.

    Thank you

    One way is to create a clip made up based on the title and the original clip. Then apply the effect.

    Another way is to use an adjustment layer.

    Good luck.

  • How to get the video intro off my google home screen I already saw it, where is the firefox logo used to be.

    How to get the video intro off my google home screen I already saw it, where is the firefox logo used to be. I started with the last update that I rebooted.

    Hello
    to change the homepage when opening firefox-press 'Alt' and click on tools-> Options.

    Main menu, you can change the URL.

    If the problem persists, you can follow these simple steps:

    Enter about: config in the address bar and press ENTER. Accept the message of 'dragons' to see the Advanced preferences screen. Use the above search box to enter the below pref.

    You can assign an empty string to stop your Firefox to retrieve "extracts" and brandLogo changes the browser.aboutHomeSnippets.updateUrl pref. Right-click this pref and select Edit then clear the value as pref in the box that appears, and then click OK. Who will also disable "snippets" that appear under the container of the research on the default home page.

    Then you must open the folder of your profile, via help > Troubleshooting Information > profile folder > > button view folder. Then close Firefox. Your profile file open with Firefox closed (Firefox '3-bar' menu key > exit/Quit), wait or two minutes, then remove the storage\moz-safe-about + home folder in the Firefox profile folder to remove the brandLogo and stored in IndexedDB code snippets to make Firefox use the default brandLogo and a defined default code snippet.

    If you later change your mind about these changes, you can reset the pref browser.aboutHomeSnippets.updateUrl via the context menu and Reset allows to retrieve the default value using the storage\moz-chest-fort-about + home folder again.

  • Re: How to get the Tempo to work properly?

    Hello

    I have problems with the service of Tempo.

    I don't get updates via this application (all the settings of this application are accurate, i.e. "full control"). I know this because there are updates available online to my laptop via the pilot site of toshiba.

    When I installed first Tempo, updates for about a month, I received, and then all of a sudden, no update came through. My firewall is blocking either of this application.

    I tried to reinstall the application, but no change in the situation.

    Does anyone know if ALL updates are available via the website of driver toshiba out tempo? Because, in the month that this service worked, I got an update of the bios, but I recently saw a bios update online and Tempo has not always reports that it is available.

    Any ideas on how to get the Tempo to work properly?

    Thank you.

    I saw in your other thread you have installed SP1 on your Vista laptop.
    There may be some compatibility problems between SP1 and Tempo

    And Yes, as far as I know Tempo bring all available updates!

    Did you look in the user manual?
    This doc is always pre-installed on laptop and provides useful information. Also how to connect a TV and use simple notebooks ports.

    A hint; You must use an s-video cable to connect the laptop to the TV.
    Then use the FN + F5 key combination to switch between display devices.
    Sometimes the special s-video option must be enabled on the TV.

    I would recommend consulting the manual of the TV also.
