Is there anyway to hide cursor other than using transparent gif image?

    It appears that the Cursor class does not have a "blank" cursor to begin with, so one could define a new "blank" cursor using the Toolkit.createCustomCursor method.

    Here's one way I've tried which seems to work:

    // Transparent 16 x 16 pixel cursor image.
    BufferedImage cursorImg = new BufferedImage(16, 16, BufferedImage.TYPE_INT_ARGB);

    // Create a new blank cursor.
    Cursor blankCursor = Toolkit.getDefaultToolkit().createCustomCursor(
    cursorImg, new Point(0, 0), "blank cursor");

    // Set the blank cursor to the JFrame.
    mainJFrame.getContentPane().setCursor(blankCursor);




    Edit

    Regarding the comment about everything inside the JFrame ending up without a cursor, it seems that the Components which are contained in the JFrame will end up inheriting the cursor of the container (the JFrame), so if it is a requirement to have a certain Component have the cursor appear, one would have to manually set the desired cursor.

    For example, if there is a JPanel contained in the JFrame, then one could set the cursor of that JPanel to the system's default using the Cursor.getDefaultCursor method:

    JPanel p = ...
    // Sets the JPanel's cursor to the system default.
    p.setCursor(Cursor.getDefaultCursor());

    frame.setCursor(frame.getToolkit().createCustomCursor(
    new BufferedImage(3, 3, BufferedImage.TYPE_INT_ARGB), new Point(0, 0),
    "null"));

    When using the LWJGL under Mac OS you need to do this:

    System.setProperty("apple.awt.fullscreenhidecursor","true");

    I solve this problem much easier:

    final Timer cursorTimer = new Timer(2000, new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
    getContentPane().setCursor(null);
    }
    });
    cursorTimer.start();

    addMouseMotionListener(new MouseMotionAdapter() {
    @Override
    public void mouseMoved(MouseEvent e) {
    getGlassPane().setCursor(Cursor.getDefaultCursor());
    cursorTimer.restart();
    }
    });

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
