Mouse Jumping when I enter a label

问题:

A bit ago I posted a question on cursors here

and I was wondering how do I get the cursor to stop jumping so what I mean is then I enter the jlabel it shows it like normal and then after a couple of seconds it jumps to a different place now when I added the frame drag method I added this code to stop this form happening 

this.setLocation(x - xMouse, y - yMouse);

But I was wondering how would add it into this method

 Toolkit toolkit = Toolkit.getDefaultToolkit();
    Image image = toolkit.getImage("C:\\Users\\christian\\Desktop\\Files\\The Iron Door Files\\TheIronDoorDev\\New Launcher\\src\\pkgnew\\launcher\\Images\\Mouse//Drag.png");
    Cursor c = toolkit.createCustomCursor(image ,new Point(FrameDrag.getX(),FrameDrag.getY()), "Cursor");
    FrameDrag.setCursor (c);
}

to stop this from happening as it can be annoying

Edit :

So now I have this code but when I run I get this 

   int x = evt.getXOnScreen();
     int y = evt.getYOnScreen();
    Toolkit toolkit = Toolkit.getDefaultToolkit();
Image image = toolkit.getImage("C:\\Users\\christian\\Desktop\\Files\\The Iron Door Files\\TheIronDoorDev\\New Launcher\\src\\pkgnew\\launcher\\Images\\Mouse//Drag.png");
Cursor c = toolkit.createCustomCursor(image ,new Point(x - xMouse, y - yMouse), "Cursor");
FrameDrag.setCursor (c);

BUILD STOPPED (total time: 11 seconds)

Edit 2 : Fixed that issue but still having the jump

回答1:

The Point parameter to createCustomCursor is used to define the "hot spot" of the cursor

That is, it describes the point in the cursor image where a mouse event will generate it's click point

From the JavaDocs...

public Cursor createCustomCursor(Image cursor,
    Point hotSpot,
    String name)
        throws IndexOutOfBoundsException,
        HeadlessException

Creates a new custom cursor object. If the image to display is invalid, the cursor will be hidden (made completely transparent), and the hotspot will be set to (0, 0). Note that multi-frame images are invalid and may cause this method to hang.

Parameters: cursor - the image to display when the cursor is actived
hotSpot - the X and Y of the large cursor's hot spot; the hotSpot
values must be less than the Dimension returned by getBestCursorSize
name - a localized description of the cursor, for Java Accessibility use

Updated

The "hotspot" defines the location within the cursor where the "click" point will be generated. In the first cursor, it's 12x5, in the second it's 10x5.

So, the position of cursor on the screen will be relative to it's top, left corner (0x0 relative). When the user presses the mouse button, the system will add the "hotspot" offset to the current screen position and generate an appropriate mouse event.

What I suspect is happening, is when you change the cursor, the system is trying to align the mouse's hotspot with the old cursors hotspot, which is causing it to jump about.
