Cursor to mouse position

I am wondering if there is a function or way that allows one to record the position of your mouse on the graph. Currently I'm trying to reposition the X and Y cursors to where I double click on the graph. I know how to set the position of the cursors using SetPostion(). The problem I'm encountering is that I can record the position mouse using OnMouseUp() but the coordinates do not relate to the scale of my graph. Does anyone have any suggestions for me? Thanks.

R0B3RT,
You didn't say what programming language you were using in your program, so I can't provide a specific example of doing this. But if you are using the CWGraph ActiveX Control, you can use KB 11H7EH1J: Using the ComponentWorks Graph Cursor Events. If you are using one of the .NET controls, let me know which language you are programming in, and I'll be able to help more.

With Standard Labview 6.1, is there a way to set (x,y) cursor-mouse position?

I am working on a project in standard Labview 6.1 that receives images from a webcam. This image array will then be analyzed to determine the position of a black dot on a white background. This dot will then correspond to an (x,y) coordinate point. We will then feed these coordinates into a program that will set the cursor mouse position to this point. However, we are uncertain on how to interface Labview with the computer mouse controls and are in need of assistance.

If you are simply wanting to set the coordinates of an existing cursor on a LabVIEW graph, then you can do that using Property Nodes. I have attached an example of this which you could take a look at.

Moving xy graph cursor with mouse and programmably controlling snap to point

Hi,
I have run into a bit of a problem. I am trying to create a program which allows a user to select a location on an XY graph by simply clicking in the vacinity of the plot. Most of it is working, however I find that I can't programmably control the snap to point function reliably.
I hope this is a clear outline of the problem:
- The cursor starts in a Free state, so that when the
user clicks in the plot area, I can set the cursor
position to the nearest point by setting the
CursorPosition using the graph's property node.
- Maybe the user didn't like the chosen location and
wants to drag the cursor over a bit. Ok, user drags
the cursor to a new position.
- Now th
e cursor position is probably not exactly on
the plot trace. If, at this point, I set the cursor
to Snap To Point, the cursor does not snap to the
nearest point on the graph (relative to its current
position), but instead to the last place a _mouse_
action placed it.
- Immediately after the new location has been set,
the cursor state has to be reset to free in case I
need to programmably move the cursor again (I
can't seem to programmably control the mouse in
any state but Free)
How do I go about getting the cursor to snap to the closest point at it's new location? I'm at a loss.
Any insight you might have would be greatly appreciated.
Thanks much!
Tere

So what is the question about... I have to use XY graph in my program. It is used in Loop while cycle. It shows the statistic of a variable. I am using cursors in this graph to check the actual value of a variable in different period of time. But there are 7 variables and it is extremely hard for user to check each value independently. So I tried to make them moving on the X axis (TIME) together using the property node (cursors reading the position (only X axis, Y axis status lock to plot) of the major cursor and follow it... Everything looks great? But it did not work when I am trying to move the major cursor manually on graph... It works only when I am using the cursor movement buttons... But they work very slowly when there is a lot of data in graph.
I want to find out is it possible to make seven coursers mouthing together By the X axe and be Locked each at its plot by Y axe manually (Using mouse moving on a graph). Is it possible? If it is than how to do it?

Control position vs mouse position

I want to create a tooltiptext for example. I have the mouse postion, the buttonposition and the window-position. So if I'm moving the mouse-cursor over the button, a light needs to go on. To find the position of the button in function of the X-axis is no problem, but from the top I can't find. My conclusion --> The "top button position" is not right.

You didn't include handy\mouse.vi, so we can't see how you're reading the mouse position. Functions that read the mouse position often report it relative to the current window. You then need to add the window position to it.
FYI: Tooltips are included in LabView 6.x. Instead of just being able to set the description of a control, on the same screen you can set the tooltip text. Just one minor reason of many reasons to upgrade.

Robot class and obtaining mouse position

The Robot class has the mouseMove(int x, int y) method which allows you to position the mouse at the given x-y coordinates. I am trying to move the mouse using relative coordinates, i.e. move 200 pixels left, as opposed to moving to 400,800. Is there a way to obtain my cursor's current position? I've looked at the MouseEvent class, and I'm not very sure that would work, as it requires input from the mouse in order to trigger.

TryPointerInfo pointerInfo = MouseInfo.getPointerInfo();
Point p = pointerInfo.getLocation();

Rotate matrix by mouse position.

Hey guys I have been banging my head against this problem for the past few hours. I have a rectangle object created, I want the rectangle's rotation to follow my mouse cursor. ( I am easily able to do this). Where things get hard is that I want the rectangle to rotate around it's bottom right corner, to do this I've found that I need to use a matrix transformation. At this point I am able to have my rectangle rotate around the bottom right point, but I cannot figure out how to have it follow my mouse cursor as well while rotating. The reason being that with a matrix you can only tell it a amount of radians to rotate (matrix.rotate) rather than just being able to set its current rotation.... Here is my code
var point:Point=new Point(myRectangle.x+myRectangle.width/2, myRectangle.y+myRectangle.height/2);
function rotateObject( event:Event ):void
          var m:Matrix=myRectangle.transform.matrix;
                              m.tx -= point.x;
                              m.ty -= point.y;
                              m.rotate (45*(Math.PI/180));
                              m.tx += point.x;
                              m.ty += point.y;
                              myRectangle.transform.matrix=m;
addEventListener( Event.ENTER_FRAME, rotateObject);
So with the current code it is constantly rotating around the bottom right corner, I have tried changing the "45" to "Math.atan(mouseX/mouseY), but again it seems that would only work if i could set the rotation of the matrix to that rather than telling it how much to rotate by....
Any thoughts or ideas would be much appreciated, thanks!

can you not calculate the new rotation based on the mouse position and the rotate by the difference with the current rotation on your rectangle?
function rotateObject( event:Event ):void
          var newRot:Number = Math.atan(mouseX/mouseY);
          var rotationDelta:Number = myRectangle.rotation - newRotation
          var m:Matrix=myRectangle.transform.matrix;
                              m.tx -= point.x;
                              m.ty -= point.y;
                              m.rotate (rotationDelta*(Math.PI/180));
                              m.tx += point.x;
                              m.ty += point.y;
                              myRectangle.transform.matrix=m;

How to Place the Cursor at Specific Position with-in a Char Field ?

Forms 4.5 ver.
Sun Solaris / Citrix env.
Char Field - Length 65434
How Can I Place the Cursor at "Specific Location"
with in a Field ?
with GO_ITEM('field Name') I can place the Cursor at Specific Field.
But, How Can I achieve to Place the Cursor at Specific
Position within that Field ?
I know, the starting position, length of string I want to hightlight with the Cursor.
tried using :
go_item('substr(field_name,position,length)') ;
but didn't work !
Is it possible ?
Thanks, Peri

The only cursor postion behavior that can be controled is the item property "Keep Position".
The following is the text from the on-line help for item property "Keep Position"
KEEP_POSITION Specifies whether the Keep Position property should be True or False. When Keep Position is True, the cursor returns to the same position it was in when it left the text item. When Keep Position is False, the cursor returns to the default position in the text item. Valid values are PROPERTY_TRUE and PROPERTY_FALSE.

Zooming image from mouse position(like in windows vista photo gallery)

hello all;
here's my situation, hope someone can help..
i wanna Zoom an image, which zoom from my mouse position
like in windows photo gallery in windows vista
so i do this..
g2.translate(iMoux,iMouy);
        g2.scale(zoom, zoom);
        g2.translate(-iMoux,-iMouy);
        g.drawImage(icon.getImage(), iSposx, iSposx, d.width/2-iValue, d.height-iBawah, null);
        g.drawImage(icon2.getImage(), d.width/2, iSposy, d.width/2-iValue, d.height-iBawah, null);the problem come when i move my mouse to the different location (like from top right to bottom left)
the zoom image displayed in the screen like jump from latest location to new location
anybody can help me...a clue how to do that?
thx appreciate your help guys

Hi Frank.
Thanks for the response.
Agreed, the pertinent question is why can't my colleague edit the JPG exported by Aperture. It's probably also worth pointing out, the same problem occurs with JPGs exported from iPhoto.
The Windows software usually plays nicely with JPGs by all acounts, just not the ones I send - which I do via eMail or my public space on Mobile Me incidently.
So, another key question is: all settings being equal (color profile, quality, etc.) are the JPGs as produced by iPhoto and Aperture indistinguishable from those produced by other apps on other platforms - i.e. does the use of JPG enforce a common standard?
If that is the case, I suspect ours might be a permissions issue.
According to the Microsoft support page on editing in Windows Live Photo Gallery, the inability to edit a picture is commonly caused by unsupported file type, or read-only attribute set on the file.
Unfortunately, he and I are not in the same place, and he's not particularly au-fait with this type of problem solving. Hence, before involving him, I'd like to know:
1. it's possible (i.e. someone else does it), and,
2. what's involved (at my end and/or his).
Thanks again,
PB

System not sensing mouse position

Starting today, my computer (iMac G5 PPC) no longer senses the position of my mouse pointer. For instance:
- The dock doesn't magnify when the mouse is in it
- None of the corners activate things like screensaver, expose, desktop
- When I select a menu in the menu bar, moving the mouse over another menu item doesn't open that menu.
In other words, OSX simply has no clue where my mouse pointer is located as I move it for all those neat automatic things. Yet, I can still use the mouse to click on items to make them work, then OSX knows where the mouse is.
I've rebooted several times to no effect, but did notice something. As apps start up, the instant a window opens, OSX will sense the mouse position for that brief moment. For example, putting the mouse over the dock doesn't magnify, but when an app window appears, the dock will magnify that very instance. Moving the mouse out of the dock area doesn't unmagnify the dock, it's stuck in that state until either another window opens, causing OSX to sense the new position, or I click any mouse button which all gets OSX's attention and senses the mouse position.
The pointer never changes when I'm over things like Links.
Strange stuff. The mouse moves fine, it's just not being detected as it moves.
Now, yesterday I installed a new ScanSnap scanner with the ScanSnap Manager software and Acrobat Standard ver. 7. But the mouse didn't have this behavior yesterday, or even this morning. This strange problem just appeared out of the blue mid-day today.
I've since used Disk Utility and Onyx, and re-installed the 10.4.9 update. I switched to another user account, no difference, so it's definitely system wide.
This doesn't stop me from using my iMac, but I just don't know how to fix this mouse issue besides a OSX re-install.

Ok everybody, I finally got proper behavior, it's just too bad I'm not sure of the procedure.
When I go to bed I usually run the mouse pointer to the upper left corner to activate the screensaver. Of course it didn't work. But I also knew that clicking a button causes the mouse to be sensed, so I was pushing some of the buttons while in the corner to see if I could get the screensaver going.
Well, after doing this, everything is back to normal operation again. So, I fixed it totally by accident. Makes me wonder if there's some features that are turned on and off somehow by doing whatever it was I did up in that corner.
Just so you know, I use a Logitech Cordless Optical Trackman. I swapped to the original Apple corded mouse but that made no difference.
I never had a chance to try the suggestions since I just read them before posting this.
Anyway, I hope I don't do again whatever it was that caused the behavior, but I am going to store this info in DEVONthink just in case something like this happens again.
Anyway, it would still be interesting if someone could shed some light on this fix I accidently found. Perhaps some hidden capabilities/features? Or just dumb luck?

MAC OS X + stage.fullScreenSourceRect + renderMode set to GPU = problem with mouse position

When setting stage.fullScreenSourceRect, stage.displayState to StageDisplayState.FULL_SCREEN_INTERACTIVE; and renderMode to GPU, mouse position is read incorrectly. This is not only for mouseX and mouseY position, but also all the mouse interactions with Sprites, Buttons etc are not working correctly.
Anybody know a solution for this issue?

Bump up.
Anybody has the same problem and have an idea how to fix it? Or please just check if you have the same problem.. I'm going to submit my game "Amelia and Terror of the Night" (successfully added to iOS store) to MAC App Store but can't do it while this problem appears.
I am disappointed nobody even verified the bugs I submitted at the bugbase.adobe.com for AIR 3.5 and 3.6

Hwo to "track the mouse position"

I m a java newbie, and need to write a small program to track the mouse position.
basically, it opens a small window, and tell you the current mouse x, y coordinate. when mouse moves, hte x, y changes...
by the way, how can i compile it to .exe file, after i finished coding.
i try this way, but so many errors.
import javax.swing.*;
import java.awt.*;

          mouseMoved(MouseEvent e);
JFrame frame = new JFrame("Mike's Mouse");
JLabel X = new JLabel("x: " + last_x + "y: " + last_y);
frame.getContentPane().add(X);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
     public mouseMoved(mouseEvent e)
          last_x = e.getx();
          last_y = e.gety();

please help.
i rewrite the code, but still cannot get it work

Mouse position on screen

is there any way to get the mouses position on the screen (not a window)?
Stephen

Component c = (Component)e.getSource();
Point p = e.getPoint();
SwingUtilities.convertPointToScreen(p, c);
System.out.println(p);

Mouse position capturing

I was wondering if there is a way to capture the mouse position w/o the use of a frame or jframe? I already know how to use the MouseListener on the JFrame/Frame, but that is no help to me since I'm not using a frame at all. Any suggestions????

What is your goal. This will work -- (the window is 1 pixel!) -- because the robot starts a "drag" and
swing has mouse capture during drag, but as soon as the use clicks, it's over...
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class X {
    public static void main(String[] args) throws AWTException {
        JWindow w = new JWindow();
        Container cp = w.getContentPane();
        cp.addMouseMotionListener(new MouseMotionListener() {
            public void mouseDragged(MouseEvent e) {
                   System.out.println(e.getPoint());
            public void mouseMoved(MouseEvent e) {
        w.setBounds(new Rectangle(0,0,1,1));
        w.setVisible(true);
        Robot rob = new Robot();
        rob.mouseMove(0,0);
        rob.mousePress(InputEvent.BUTTON1_MASK);
        rob.mouseMove(100,100);

Detect Mouse Position?

I can't (within actionscript 3) determine where the mouse is
relative to the flash player window.
I can get stage.mouseX and stage.mouseY but those coordinates
are in relation to the size of the entire ORIGINAL stage at compile
time.
I need to know where the mouse is in relation to the window
playing the swf, which is significantly smaller than the original.
That is the play screen has been resized.
If I zoom way in and scroll to the right edge of the stage
and mouseover a spot on the right edge, then trace the mouse
position (in a mouseover event proc) it shows me a number that is
the width of the ORIGINAL stage. It seems to be completely
oblivious to the play window.
Is there any way at all to determine where the mouse is
relative to the play window?
For example,
if the original stage is 1350 and the play window is 540 and
I'm zoomed WAY in and scrolled all the way to the right and
I put the mouse directly in the middle of the window,
I need something that tells me (in actionscript 3) that the
mouse's x coordinate is at 270, NOT 12XX (somewhere near the end of
the orginal size of the stage).
Is this possible in Flash C3??

Hi there!
I don´t know if it´s right but have you tried
localX
localY
from the occuring MouseEvent?
Hope that helps :)

Convert mouse position to image position

Using a zoomed IMAQ image in an image control, I want to recover the position of the mouse in the co-ords of the underlying image. LastMousePositionX (and Y) give the info I want but they are one click in the past and not the current position. Amazingly, there doesn't appear to be an equivalent CurrentMousePositionX. I can't seem to find the info I need to do the conversion manually. The mousedown event returns the current mouse position and I can get the position in the image container by subtracting off its left and top position. But to convert this to the image position I need to know both the zoom and where the images origin is relative to what is displayed. I can't seem to find that origin position in the list of property nodes. The only thing I can seem to come up with is to extract the info from teh image information string, but this seems like an incredibly poor way to extract such obvious information - espeically since the info must be calculated to put in the string anyway. Can anyone help with this?

Hi,
I am confused why you get the mouse position one click in the past because it seems to work ok for me. I've had to use four of the image properties to recreate the effect using the mousemove event, but this seems to give the same values as the Last Mouse Position property so I think it does what you want. I couldn't see an origin property so I did the conversion using the position given at the image center. I wanted to post a snippet here but I'm new to posting and couldn't seem to get it to work for the whole block diagram, so I'm using a screenshot instead. I hope this helps in some way.
