Determining Mouse Position

I'm trying to determine the position of the mouse cursor relative to my content pane, while over an added component. I'd rather not do any calculating, since MouseEvent.getPoint() returns the point within the component the mouse is overbut will if no other alternatives come about.
Any suggestions would be appreciated.

use SwingUtilities.convertMouseEvent or which ever convert() method you like.

How can I determine mouse position within a 2D picture control

I have an application where I'd like the user to be able to interact with objects drawn in a 2D picture control using the mouse. In order to do this, I need to translate between screen coordinates, which are passed with the mouse events, and coordinates in the 2D picture control.
The problem I'm running into is that I can't find a way to determine the screen coordinate of the upper left hand corner of the 2D picture control's drawing/client area. I tried using the picture control's "Position" property, but this results in an offset due to the difference between the upper left hand corner of the picture control (including the label, etc.) and the upper-left hand corner of the drawing area. See attached VI.
Does anybody know how to get the screen coordinate of the corner of the picture control's drawing area?

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 :)

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.

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?
Here is the bug reported, but there is no response yet.
https://bugbase.adobe.com/index.cfm?event=bug&id=3486120
Greg.

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
thanks

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.*;
import java.awt.event.*;
public class mouseWin {
public static void main(String[] args)
          protected int last_x=0, last_y=0;
          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)?

Component c = (Component)e.getSource();
Point p = e.getPoint();

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);

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.

Get mouse position during Custom UI Draw event?

I am building a Custom UI for one of my plugin effect.
I want to get the mouse position during the Custom UI Draw event (PF_Event_DRAW), but cannot manage to get it.
From what I understand, it seems we can only get the mouse position during the events PF_Event_DRAG, PF_Event_DO_CLICK, and PF_Event_ADJUST_CURSOR.
I tried to use PFAppSuite4::PF_GetMouse() too, but this resulted in the error message "After Effects error: internal verification failure, sorry! {PF_GetMouse can only be called during valid events.}".
Therefore I want to store the mouse position during PF_Event_ADJUST_CURSOR, and use it later during PF_Event_DRAW.
Where can I store those values in a "clean" way (ensuring there will not be conflicts if two instances of the same effect are running, etc)?
Or is there an easier method to get the mouse position during a Custom UI Draw event?

//SequenceDataVars is the name of your data structure
//this is how you create the sequence data
out_data->sequence_data = PF_NEW_HANDLE(sizeof(SequenceDataVars));
SequenceDataVars *seqData =
(SequenceDataVars*)PF_LOCK_HANDLE(out_data->sequence_data);
//and now you can store stuff in it.
seqData->var1 = 7;
//after it's created, on other calls, you just do a simple cast
SequenceDataVars *seqData = *(SequenceDataVars **)out_data->sequence_data;
seqData->var1 = 100;
//this is how you delete it. (if you don't delete it, it will be saved with
the project, and loaded on the next session. (if you want)
PF_DISPOSE_HANDLE(out_data->sequence_data);
there's more to know, so look up SequenceSetup, SequenceSetdown, ect in the
sample project.

Checking Mouse position every second?

Hello,
I have a program that needs to check the mouse position on the program's window every loop, but if I use MouseMotionListener's mouseMoved(), it is not what I want because it checks ONLY when I move my mouse, it doesn't check if I don't move my mouse. For example, I have a while loop will check if the mouse pointer now in the area of (25, 50), the program will do something. Thus what should I use? I tried moveEntered(), it doesn't work as well any hints?
Andy

okay, for example, like Warcraft 3, starcraft type RTS game, when you move your mouse pointer to the edge of the screen, the screen will scroll over the map. But remember when you move to the edge of the screen, it will move automatically so you don't need to move your mouse until you want to stop moving the screen, you move away your pointer from the edge right? With mouseMoved(), it doesn't work that way cuz whenever it checks mouseMovement only, if there is no mouse movement, it doesn't know whether if the pointer is on the edge or not. How do I check that, since I don't wanna use a Runnable class to do that, I rather use a loop to check it. Which method that I can get the mouse pointer position by not implementing MouseListener.

DnD - Get Drop Mouse Position

I want to Drag some image file from a JList, and then drop it on a JPanel. The dropping on the panel functions. The problem is, i would like to get the position of the mouse, when the item is dropped on the panel. I use the panel to visualize graphics with Graphics2D, and the image dragged from the list should then be displayed at the position on the panel, where it is dropped. So how could i get this position? I have added a MouseListener to the panel, but it does not react on the mouse events which are caused by the DnD action.

I am really helpless... Is this a stupid question or does nobody know the answer?
I just want to get the mouse position of the drop, after a drag and drop.
I found a MouseDragGestureRecognizer Class, but i am not able to implement. Actually i have just a JList, from which Strings are dragged, and a JPanel, on which the Strings are dropped.
The drag and dropping functions, but i need the mouse position on the JPanel, when the String is dropped.

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.
