这个应该将鼠标光标移动到我/你的屏幕上的1000x1000位置（即距我屏幕的绝对0x0坐标1000px ...并且应该总是在同一位置）。 ......它不...它取决于按钮的位置。为什么？

造成这种情况的原因是什么？
...这曾经在旧笔记本电脑上工作。即windows 10,1 intel显卡，1 nvidia显卡，1920x1080显示器。
我目前在3840x2160分辨率上使用Windows 10,2 SLI显卡调整比例因子似乎没有做任何事情。
... i我还使用jdk8。
使用-Dsun.java2d.dpiaware = true或-Dsun.java2d.dpiaware = false vm选项似乎没有做任何事情。
[edit] ...对于问题重复问题......这不是重复的问题。该问题的解决方案毫无用处。
这不起作用！
for（int count = 0;（MouseInfo.getPointerInfo（）。getLocation（）。getX（）！= x ||
MouseInfo.getPointerInfo（）。getLocation（）。getY （）！= y）&&
count< 100; count ++）{
new Robot（）。mouseMove（x，y）;
}
次优，可怜不好解决方案......但工作 ......我在这个问题上浪费了太多时间而不是我应该拥有的。

理论上可以获得相同的结果通过使用awt.Robot实例逐个像素地移动...这似乎工作得更好。
是啊...我确实尝试计算相对目标指针目标的位置基于鼠标光标的当前位置和所有内容...但它仍然基于模糊地难以获取有关DPI缩放和任何无意义的MS决定在WPI和GDI输入事件中实现的信息处理例程。
...直接将其移动到0x0然后1000x1000使得它导致由（2000x1400）定义的光标位置...没有时间也没有耐心去弄明白。 ......解决方案有效。故事结束。
public class MoveCursor extends Application {

@Override
public void start(Stage stage) throws Exception {
Button b = new Button("X");
b.setOnAction((event) -> {
try {
new Robot().mouseMove(1000, 1000);

this should move the mouse cursor over to position 1000x1000 on my/your screen (i.e. 1000px away from the absolute 0x0 coordinate of my screen... and should wind up always in the same position). ... it doesn't... it depends on where the button is. why?
what's causing this?
... this used to work on an old laptop. i.e. windows 10, 1 intel graphics card, 1 nvidia graphics card, 1920x1080 display.
I'm currently using Windows 10, 2 graphics cards in SLI on a 3840x2160 resolution scaled at 175%.
adjusting the scaling factor doesn't seem to do anything.
... i'm also using jdk8.
using the -Dsun.java2d.dpiaware=true or -Dsun.java2d.dpiaware=false vm options doesn't seem to do anything.
[edit] ... for quesiton duplicate issue... it's not a duplicate of that. the fix in that question is useless.
THIS DOES NOT WORK!
for(int count = 0;(MouseInfo.getPointerInfo().getLocation().getX() != x ||
MouseInfo.getPointerInfo().getLocation().getY() != y) &&
count < 100; count++) {
new Robot().mouseMove(x, y);
}
Sub-optimal, pathetically bad solution... but it WORKS... and i've wasted far too much time on this issue than i should have.

Theoretially one could achieve the same results by using an awt.Robot instance to move something pixel by pixel... this seems to work better.
yeah... and i did try to calculate the relative target position of the pointer destination based on the current position of the mouse cursor and everything... but it's still based on obscurely difficult to acquire information about whether or not DPI scaling and whatever nonsense MS has decided to implement in the WPI and GDI input event processing routines.
... moving it directly to 0x0 then 1000x1000 makes it result in a cursor position defined by (2000x1400) ... don't have the time nor the patience to figure it out. ... solution works. end of story.
