Zoom an Image whereever the mouse cursor is placed

Hi,
I have to zoom the image where ever the mouse cursor moves.
If i am moving the mouse at the position (x,y) then that part of the image has to be zoomed,
so that the image pixels will be visible properly to the user.
The image is set to label.
I know that the code has to be written in MouseMotionListener.
I will get the position of (x,y) when the mouse is moved on the image.
But how to ZoomIn the image where ever the mouse cursor is?
Can any one suggest me what i have to do exactly.
Thanks & Regards

Hi,
I saw that code some time before.
The code is using java5, but i am using java 1.4

How to extract the mouse cursor image without using JNI

I want to get the image of the mouse cursor of the system using java. The Robot class captures the screen only, but the mouse icon image is not the part of the screen, so it is not easily detected. But we can get the mouse cursor position using API, but how to get the exact image icon, without using JNI. I don't want to generate my own cursor at that position.

I am building a Remote Desktop kinda app using java..... I want the screen of the remote comp to be viewed on my screen and generate events from my machine to the remote machine. So, I am capturing the screen images of the remote machine. But the cursor is not part of the screen object. i want to extract the cursor image icon from the remote machine to my machine and render the image.

Making the mouse cursor invisible.

I am currently in the deployment phase of software made for two touchscreen kiosks.
When moving the applications over to these kiosks I realized that we needed to make the mouse cursor invisible.
I have tried the
Cursor cursor = new Cursor();// ALthough i was unable to find a cursor constant that gave me an invisible pointer.
testFrame.setCursor(cursor);
Any ideas how I could remove the pointer from view alltogether?

Toolkit tk = Toolkit.getDefaultToolkit();
Image image = tk.getImage("yourPicture.gif");
Cursor invisibleCursor = tk.createCustomCursor(image, new Point(0,0), "invisible cursor");I usually use a 1 x 1 transparent gif.

[SOLVED] How do I autohide the mouse cursor in xorg?

My Google Fu isn't working for me today. I've found references to autohiding the mouse cursor in xorg, but no examples. Anyone know the right incantation for xorg.conf?

From the man page:
unclutter removes the cursor image from the screen so that it does not obstruct the area you are looking at
That's my reason, anyway.
I mostly use the keyboard, so often the mouse cursor is just an eyesore. I can move it out of the way, but why not hide it altogether?

Remove the mouse cursor

Hi to all,
I have to make a brief presentation of the show with a medley of the songs.
Since it is not possible the coexistence of a number of slides with a single song and other slides with other songs I had to create two projects, the first with credits and in the last slide a giant rectangle with the hyperlink for the second with the medley.
It all works fine (just remember to load the second project in Keynote before to click the hyperlink ), and in my old MB works very fast, but when I click on the rectangle it appears the mouse cursor and it is not very professional.
Is there a way to remove the display of the cursor? I can accept also a tiny dot or similar, the main thing is that at the moment of blank the audience don't see this "thing" shaped like a small hand moving in the background scene searching for the "nothing" to click.
The config is: Macbook mid/late 2009, 13", 4 Gb RAM, Mountain Lion 1.8.2 / Keynote 5.2.
Thanks and sorry for my bad english.

you must not create a small button, you need a large button, no need to move the mouse at all as the button is always in the same place.
As I wrote: I'll have to try this when I'll have a projector (or an external monitor), at this time with the computer screen set to 1920x1200 while the project is 800x600 (as most 4:3 projectors) I can't click perfectly into the corner, there's too much scope.
buy a two button remote, same price as a cheap mouse
Wow! € 32.00! I know mouses that cost even € 9.00 (for example the Logitech that I use
with the MacBook) and when I'm on stage I prefer to use less laser / wi-fi / bluetooth possible. No, I have to put the money aside and buy a trackball, as I have written before is also useful for other applications.
which ever show pointer preference you select the cursor is going to be visable because you are using hyperlinks. However, if you use the static cursor position extreme bottom right, the cursor wont be seen as it is so small and partially of screen - also use command c to hide it.
I'm definitely getting older (will be 48 in April... poor me!), but I can't understand: if the projects are 99% composed of slides with images, audio, transitions, etc.. and only the last slide has an hyperlink that is used to connect the following, why should I risk to let see the mouse cursor at the slightest movement, error, earthquake ... and everything that could happen in a location of a theater director?
The "C" key is used to display / remove the cursor, but only if the mouse is completely still, while the other setting (the one I use) the mouse is never! I could get close to the lower right to the end of the project and then click the hyperlink ... or not?

On startup Mac Pro I get a blue screen and a cursor on the upper left. The mouse cursor shows up independently. Is it likely a video card failure?

On startup Mac Pro I get a blue screen and a cursor on the upper left. The mouse cursor shows up independently. Is it likely a video card failure?

I managed to boot the computer and get the desktop to show. I now have a "repaired" computer. There are several problems that have cropped up. One is that I can only start up now in Safe Boot mode. Is there a way to turn it off? Also, I do not have a sound list, so I can't access anything requiring audio. Google Chrome only shows up as a white screen. Pictures that loaded before don't load in browsers, etc. Any suggestions? I figure I should reinstall Mac OS Lion for starts, maybe even do a mirror backup and reformat the drive. I think this drive has turned into scrambled eggs...what a headache!

How to change the mouse cursor icon type when mouse moves out of client area ( propertysheet) WTL?

I got stuck with an issue in property sheet .I want to load different cursor when the mouse position is within the client area and load another when moves out of the client area.
In the porpetysheet I added four page. In the first page when I click next I am loading cursor of IDC_WAIT type and loading IDC_ARROW when the mouse moves out of the client area.
In the page class I triggered the event for WM_MOUSEMOVE as follow:
MESSAGE_HANDLER(WM_MOUSEMOVE, OnMouseMove)
LRESULT OnMouseMove(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/)
if(TRUE == m_bIsNextBtnClicked)
::SetCursor(LoadCursor(NULL, IDC_WAIT));
else
::SetCursor(LoadCursor(NULL, IDC_ARROW));
return TRUE;
This event is getting triggered and absolutely had no issue with this. Similarly I tried adding `MESSAGE_HANDLER(WM_MOUSELEAVE, OnMouseLeave)` this event making an assumption that this will get triggered if the mouse moves out of the client area, but
this event did not get triggered at all.If this is not the mouse event to be triggered for mouseleave which event should I trigger?
LRESULT OnMouseLeave(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/)
::SetCursor(LoadCursor(NULL, IDC_ARROW));
return TRUE;
Now when I click Next button , **I was actually calling a function which is taking sometime to return** . Before to this function I am loading IDC_WAIT cursor i.e.,
`::SetCursor(LoadCursor(NULL, IDC_WAIT));` .
Now when move the mouse cursor on to the non-client area I want to load IDC_ARROW cursor i.e.,
::SetCursor(LoadCursor(NULL, IDC_ARROW));
When the moves on to the non-client area I am handling the mouse event in sheet derived class as follows,
MESSAGE_HANDLER(WM_NCMOUSEMOVE, OnNCMouseMove)
LRESULT OnNCMouseMove(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/)
::SetCursor(LoadCursor(NULL, IDC_ARROW));
return 0;
This event is not getting triggered until unless the function in the Next button event is executed.
I want both of them to be done in parallel i.e, click Next button now hover mouse on the client area, Busy icon should come and when mouse moves out of the client area then IDC_ARROW icon should come.
LRESULT OnWizardNext()
::SetCursor(LoadCursor(NULL, IDC_WAIT));
m_bIsNextBtnIsClicked = TRUE;
BOOL bRet = MyFun();
m_bIsNextBtnIsClicked = FALSE;
//Until this function(MyFun()) is executed **WM_NCMOUSEMOVE**
//event is not getting triggered.But this event should get triggered and I
//should be able to see the change of cursor within and out of client area.
Can anyone kindly help me to solve this issue.

Get rid of the mouse cursor when on desktop touch devices

Hi there,
I'm using sap.ui.commons controls to build my application. However, this application will sometimes be used on touch devices like large touch screen HDTV connected to a desktop Windows PC.
When clicking on a button, the button gets focussed. However, as clicking on a control moves the mouse cursor, too, the button gets a mouse over look and feel and the focus style applied.
Is there a way to disable the mouse over events and style sheets for desktop controls in an easy way? I want to get a similar behaviour like using an application on a device without a pointer (like a tablet or smartphone). No mouse over, no focus.
Regards
Tobias

Hey Tobias,
have a look at this Thread: javascript - Disable hover effects on mobile browsers - Stack Overflow
It helped me and might contain a solution to your problem as well!

Getting the name of the window under the mouse cursor

Hello All
Is there a way to receive a window name of the window under the mouse cursor? All windows in interest are LV windows, and all of them works separatelly. After the mouse click I would like to get the window name.
The reaso nfor asking is that I have a sequence of setting of different windows. I need to create a doccumentation and I need all windows front panels send to MS Word.
I thought that my application can read the window names and by using the LVwutil32 get the front pannels of the windows and send them to MS Word.
Problem is that in the library I do not have a function like "Window on Top.vi" or something like that.
Anyways, the problem for me now is how to get an active (most top) window
name?
thanks
Pawel

Hi Pawel,
I found the following VI in my "trunk" that I made a while ago (written in LV6.0.2). It returns the active VI (and thereby) the Window name. Mayby you have some use of it, but I believe this is what you want. Only works for Windows though.

Why does the mouse cursor move to away from the currrent application without the mouse being moved

the mouse cursor moves away from the current application without the mouse having been moved - this started with the new version - re-installing Firefox makes the problem go away for a short period - re-installing is not a solution
== This happened ==
Every time Firefox opened
== a few days after installing 3.6.3

Hello Jim.
It's probably one of three things:
#your mouse is getting old (this behavior is common in old optical mouses);
#you have software that is making your mouse cursor behave unexpectedly (I know of an option in Windows that will automatically move your mouse to windows buttons...);
#or you may be having a problem with some extension or plugin that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Bookmark shortcut is not working if the mouse cursor is focussed in flash plugin.

I was trying to open bookmark panel using shortcut keys [ctrl+shift+B] when the mouse cursor is focused with flash plugin. But it fails to open. But i clicked the page and tries it again it opens the bookmark panel.
Try with the following link
[Eg: https://learnable.com/courses/a-crash-course-in-mobile-web-design-195]
This may or may not be a issue.
Its just a suggestion..

You're welcome

I want to turn my macbook air off. the shut down button already appeared but the mouse/cursor just hang and won't work. even after pressing the enter button to shut my mac off won't work. what will i do?

i want to turn my macbook air off. the shut down button already appeared but the mouse/cursor just hang and won't work. even after pressing the enter button to shut my mac off won't work. what will i do?

This is not a reply. I just want to elaborate on this problem.
My computer freezes occasionally when it is used after being sleep for a while. The spinning ball appears and everything is totally disabled. Nothing on the keyboard works.
The mouse moves, but does not work.
The only solution is to turn the power off and on (losing all data in open applications.)
I kept the System monitor running on the side to find out which program was running when the computer froze. The Monitor as well as all other applications froze, but the data showed:
Firefox 18.4%
Activity Monitor 0.9%
Firefox Plugin 0.2%
This is all the information I have. By the way, I am using iMac with OS 10.6.
