Programmatically change mouse cursor size

LV 8.5 on Windows XP
Is there a way to change the size of the mouse cursor (custom or otherwise) programmatically? I can load custom cursors using included vi's but can't find a way to change the size - the cursor vi's are locked so I don't know what is going on behind them.
Thanks

smercurio,
I had found that thread but the API example is written in 5.1, unfortunately I have wiped this machine several times since running 7.1 and would rather not reinstall if I can avoid it. (As I understand it 7.X can open the 5.X and THEN I can open in 8.X)
I will look around for a machine running 7 and go from there but any other suggestions would be appreciated.
Thanks again!

  • Changing Mouse Cursor with a Thread

    Hi all
    I am trying to change mouse cursor inside a thread for a graphical program so that the GUI does not freeze while new image is calculated and shown on the main frame. I have the below code. It works altough not the way it should. Forexample, when I press accelarator keys to show an image (ctrl+D) I see strange characeters on the frame and they disappear when the image is shown. Also I use scroll pane to show the images but when I use this thread it does not display scroll bars when the image does not fit into the viewing area (a panel). If I don't use this thread scroll bars apeear as they should. I could not find what is causing these strange behaviours. Also after image calculaed and shown on the screen, the thread should be terminated, right? But how? I could not find exact info on this. Any ideas on these? Thanks.
    pp = new PixelPanel();
    jsp.setViewportView(pp);
    pp.addMouseMotionListener(this);
    setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
    thread1 = null;
    thread1 = new Thread("thread1")
    public synchronized void run()
    try
    pp.showGrayImage();
    finally
    setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
    thread1.start();

    I am trying to change mouse cursor inside a thread

  • Problem with i-Planet and change mouse cursor

    Hello, I know how change mouse cursor using Toolkit.getdefaultToolkit().createCustomCursor(Imagen,new Point(0,0),String) and setCursor. It works in a local applet but it doesn`t in my aplication. This aplication attach a i-Planet web server and displays the following error:
    java.lang.NoSuchMethodError: java/awt/Toolkit: method createCustomCursor(Ljava/awt/Image;Ljava/awt/Point;Ljava/lang/String;)Ljava/awt/Cursor; not found
    Where's the problem? Maybe an incorrect jdk version. I don�t think so because I use 1.3.1 version and this method works since 1.2 version.
    Thank you for all.

    hi,
    iplanet has its own jar files in \Netscape\Server4\bin\https which contains the same jar files as it is in jdk dir...so importing ur jar files thru the environment might create a similar problem

  • Mouse cursor size - SOLVED

    I need a larger mouse coursor for visibility.
    The wiki says to use "Xcursor.theme" and "Xcursor.size" in .Xresources. I cannot get either of these to work.  I can select the cursor appearance with "xterm*pointerShape" but that does not help with the size. Are there any larger cursors available anywhere?
    ~/.Xresources is sourced by xrdb in ~/.xinitrc
    If it makes any difference, I don't use a desktop manager; just spectrwm as window manager.

    cursor size, I believe, only applies to cursor files using libxcursor.  See the -xcf option of xsetroot to use it.
    I just confirmed this works, though information on what an "x cursor file" is is sparse.  The simplest was to install xcursor-themes from [extra].  This includes many good cursor files in /usr/share/icons/whiteglass/cursors.   Once installed, try the following
    xsetroot -xcf /usr/share/icons/whiteglass/cursors/left_ptr 32
    or change the 32 to adjust the size.
    Note that some client windows (mostly terminals and text fields) define their own cursors; these will not be changed by this setting.

  • Can I programmatically change printer paper size from ActionScript?

    Hi,
    I'm a newbie Flash/ActionSript developer and I have been searching for answers for a while with no luck. I wonder if I can get some pointers from this forum.
    I'm trying to programmatically print a movie clip to 8.5" x 11" plain paper regardless of the current paper size setting in the printer. e.g if the user's printer is currently set to use paper size A4, can I change the setting to Letter (8.5" x 11") from ActionScript at runtime? I use PrintJob class for printing the movieclip.
    According to the ActionScript online API spec ( http://www.adobe.com/livedocs/flash/9.0/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context =LiveDocs_Parts&file=00002066.html), I can only READ the paper size setting after the call to PrintJob.start. I can't believe that we are not allowed to change the setting. Maybe I missed something here. Can somebody help me out?
    Thanks in advance!

    you can't change the paper size used in client side printer.

  • Change mouse cursor over graph cursor.

    Is there a way to change the mouse cursor as it moves over graph cursors when using trackmode TrackDragCursor? To indicate that you can position the cursor.

    You could accomplish this with the graph's CursorMouseMove event. For example, create a new project with the NI Measurement Studio AppWizard and follow these steps:
    Add a graph to the dialog. Right-click on the graph in the dialog editor, click "Class Wizard ...", click the Member Variables tab and add a member variable for the graph called m_graph. Click OK.
    Right-click on the graph in the dialog editor and click on "Events ...". Add an event handler for CursorMouseMove called OnCursorMouseMove and add an event handler for PlotAreaMouseMove called OnPlotAreaMouseMove. Click OK.
    Go to the header file for your dialog class and add this to the bottom of the class declaration:
    private:
    bool m_cursorChanged;
    HCURSOR m_defaultCursor;
    HCURSOR m_crossCursor;
    Go to the source file for your dialog class and add this to the end of the
    OnInitDialog method:
    m_graph.TrackMode = CNiGraph::TrackAllEvents;
    m_graph.Cursors.Add();
    m_cursorChanged = false;
    m_defaultCursor = ::LoadCursor(NULL, IDC_ARROW);
    m_crossCursor = ::LoadCursor(NULL, IDC_CROSS);
    Add this to your CursorMouseMove event hander:
    if (!m_cursorChanged)
    :etCursor(m_crossCursor);
    m_cursorChanged = false;
    Add this to your PlotAreaMouseMove event handler:
    if (m_cursorChanged)
    :etCursor(m_defaultCursor);
    m_cursorChanged = true;
    Run the application. You should see that the mouse cursor changes to a cross when you mouse over the cursor.
    Hope this helps.

  • [Solved] Change mouse cursor in Awesome.

    I can't change the mouse cursor in Awesome. I added "Xcursor.theme: aero-drop" in my .Xdefaults and "xrdb ~/.Xdefaults" in .xinitrc, but the cursor is still the default black one. I searched everywhere and I couldn't find how to change it. Can you give me a hand? Thanks.

    It looks like the package in aur is messed up, It isn't extracting the themes and these are dead links to the tar.gz's.
    navi>> sudo pacman -Ql xcursor-aero <<~
    xcursor-aero /usr/
    xcursor-aero /usr/share/
    xcursor-aero /usr/share/icons/
    xcursor-aero /usr/share/icons/aero-drop.tar.gz
    xcursor-aero /usr/share/icons/aero-extra-large-drop.tar.gz
    xcursor-aero /usr/share/icons/aero-extra-large.tar.gz
    xcursor-aero /usr/share/icons/aero-large-drop.tar.gz
    xcursor-aero /usr/share/icons/aero-large.tar.gz
    xcursor-aero /usr/share/icons/aero.tar.gz
    you could manually extract the aero-drop.tar.gz into your ~/.icons folder and it should work.

  • IDCS5 Win - changing mouse cursor

    At times I have code that processes a lot of data in ways that are not amenable to progress bars (for example, saving a single, large file to disk).  During those times I would like to change the cursor from its standard arrow to another standard such as an hourglass.  I see lots of general documentation on changing cursors that are specially made, but nothing that describes the process for changing from one standard cursor shape to another.  Nor is there any sample code/snippets that demonstrate the procedure, as far as I could find.  Does anyone have a suggestion where to look or what boss to use to change a mouse cursor from one icon to another?
    TIA!
    John

    I took a quick look at the header file and it all seems waay too simple.  Are you sure you're talking InDesign here? (grin).
    Thanks Dirk.  This is what I was looking for.

  • Change Mouse Cursor Inside JTextPane

    Hello Everyone,
    I am trying to change the mouse cursor of a specific text of a JTextPane to:
    setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));This specific text is a hyperlink which its color is blue and it is underlined, so I want to have the mouse cursor changed to make clearer that you can click on it.
    I thought about trying to track the mouse position inside the JTextPane until it reachs the text position but I am not aware of any class that provides this feature. Does anyone know or have another ideia?
    Any help is appreciated,
    Thanks in advance

    This specific text is a hyperlink which its color is blue and it is underlined, so I want to have the mouse cursor changed to make clearer that you can click on it.That's the default behavior (in the default Metal LaF, at least) when you setEditable(false). And IMO it doesn't make much sense to change the cursor or allow hyperlink navigation when the text pane is editable.

  • Showing a "Please wait..." window / Changing mouse cursor to hourglass

    Can one of the following be done using javascript:
    1) Show a "Please wait" window (when using synchronous SOAP requests) with the ability to "hide" it
    2) Change the mouse cursor to hourglass
    I went over the JS API and found nothing, any ideas?

    Was the PDF opened within a web browser and was the PDF on a web server?

  • Mouse cursor size does not accurately reflect brush size

    Mouse cursor does not reflect brush size in Photoshop CS5 on an iMac 10.5 OS. If I try to draw two parallel lines with the edges touching by aligning the edge of the cursor circle, there is a gap between the lines, no matter how hard I set the brush.
    I am using a Wacom Intuous 4 mouse, but the problem persists with the standard mouse after I remove the Wacom driver, so the Wacom people say this is a photoshop problem.
    Cursor size is larger than the effect size whether I am using the paint brush, history brush, clone or healing brush.

    Bingo!
    The Mac OS setting seems to have been the culprit
    Thanks

  • Change mouse cursor appearence in script

    Is it possible to change the appearance of the mouse cursor in a script?
    A couple of the scripts I've created takes a little time to execute, so I'd like to change the cursor to the hourglass while waiting for the script to finish (and then change it back to normal at the end of the script).
    Are the other ways of letting the user know that a little patience is required?

    Hi Salte,
    The following commands show a progress display in the status bar:
    Call AutoLoopInit()
    Call Pause(10) 'Replace this line by your time-consuming task
    Call LoopDeInit()
    Call Pause(5) 'Just to see what happens when the script stops
    In the user dialog boxes you could use the method BeginWaitCursor to display the mouse cursor as an hourglass.
    Hope this helps,
    Ralf

  • Change mouse cursor to pointer

    Hello!
    I have an Image control that I use to perform an action on
    click.
    How can I make the mouse cursor change to pointer on
    mouseOver and back to default on mouseOut, please?
    Thank you!

    Assuming you're talking about the hand-pointer cursor, you
    need to set three properties (useHandCursor, mouseChildren and
    buttonMode), as the attached example shows.
    If you want to use a cursor besides the default pointer,
    hand-pointer or busy cursor, then you need to dig further into
    using the CursorManager. It's a little bit of extra work but it's
    not too bad;
    null
    see
    the LiveDocs entry on setting and removing cursors
    Hope that answers your question.
