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.

Get Current Mouse Position

Is there a way to get the current mouse position on the screen? Unfortunately, I cannot use a listener to provide the mouse position, because I don't know what components (if any) that the mouse is over. I am trying to draw in the glass pane during a drag and drop. During a drag and drop, the glass pane does not get mouseEntered or mouseMoved events (which I would have used to get the ouse position if I could). So I was hoping for a static method that I could use within the glass pane's paint method to give me the current absolute position of the mouse.

a time ago i used the glasspane and the mousemotionlistener works perfect. you only should be sure to show ( setVisible(true) ) your glasspane. the best way is to look onto the java tutorial how they did it.

Get the mouse position

If I have a frame and some panels on the frame, it seems I should not add the mouselisteners to the frame, but the panels. Now I can receive the mouse events. But when I try to get the mouse's position, they are the position's related to each panel. How can I get the positions associated with the frame?
Thanks!

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.

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.

Mouse position always zero

Hello!
I am developing a rather big application in Labview ver 8.2.
I have a problem with getting the mouse position inside a picture.
The property node mouse->mouse position always returns (-1, -1) or (0, 0). The (-1, -1) returns if the mouse is positioned over a scrollbar.
My problem is that the (0, 0) is returned for every position inside the picture.
Now i wonder if anybody has any suggestions how to get the mouse position to be returned correctly.
Best regards
Erik Johansson

Are you saying that you cannot reproduce the problem if you reduce it to a very small program (e.g. a loop containing only an image, appropriate property node with indicator and a small wait statement)?
Where did your code come from? Was it converted from an earlier version or coded from scratch in 8.20? Have you tried deleting the current image indicator and creating a new one?

I have a software demo that I'm working on (Captivate 5). From slide to slide, usually Captivate uses the start position of the mouse based on the end position of the mouse on the previous slide. But sometimes it seems to lose that position, and starts the mouse at the top left of the screen. Is there any way to change that starting position, or fix this little bug?
Thanks,
Joel

I'm having a similar problem. I've found that my mouse position changes to top left on all slides immediately following a FMR slide. I've tried to manually reposition the mouse origin by drag-and-drop and right-click/align to..., but neither work.
I've installed the 12/10 patch.
Any suggestions?
Thanks.

Getting mouse position without a listener

Hi all,
I'm trying to achieve the equivalent of Component.getMousePosition() that Sun
so kindly put into 1.5, without forcing all my users to immediately upgrade to 1.5.
Any ideas? Just the normal relative-to-component mouse position is all I need, but I have to get it even if the mouse hasn't moved, so there are no events.
Thanks a lot

I guess the easiest way is still to use a MouseMotionListener that you could add to your top level container. You could then store the value of the last position and still be able to access it even if the mouse hasn't moved.
You might also want to use the following method : SwingUtilities.convertPointFromScreen(Point p, Component c);

Mouse Position at dragDrop event

I'm dragging and dropping items between canvas containers. When I drop an item, the dragDrop event fires. However, I can't seem to find the mouseX and mouseY values of the drop target container, at the point when the item is dropped. Once the mouseDown event fires to start the drag, it seems as though Flex stops capturing the mouseX and mouseY values.
I put a mouseMove event listener on the container where I'm dropping, and as soon as the mouseDown event starts, the mouseMove event stops.
I looked at mouseUp, and while that gives me the correct current mouse position, it is triggered after the dragDrop event, making it too late to use the x and y position of the item I dropped.
How do I find where the point where I dropped the item?

As soon as the mouseDown event is triggered, the mouseMove event no longer triggers. Thank you for the link. I've read that many times while working on this. What it doesn't address is the position of the item dropped. The only way I can think of to get around this is to listen for the mouseUp instead of the drapDrog event, but that should not be necessary. Use the code below, as an example. No matter where you drop the panel in the second canvas, it puts it at the y value of the mouse at the moment the doDrag (or mouseDown) event triggered.

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?

How can I get a cursor position?

Hi Everyone!
In my TextArea, there is a blinking cursor.
How can I get the cursor position not the mouse position.
Thanks,

Thanks JefferyGong!
That is selection index number, not the coordinate point.
I want to know point position.
Gyi

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
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.EventListener;
public class mouseWin implements MouseMotionListener
public static void main(String[] args)
               int last_x;
               int last_y;
               last_x = 0;
               last_y = 0;
               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 void mouseMoved(MouseEvent e)

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 :)
