Java 修改从Desktop.Browser打开的窗口的位置和位置

如何编辑此处打开的窗口的位置和大小？需要能够跨平台进行。如果没有跨平台的解决方案，桌面上使用的解决方案是什么

（这是一个离题的问题，但我可以放大网页的一部分吗？）

---

（这也是一个问题，但如果有其他方法打开窗口，包括把手，怎么做？

这就是我在Windows平台设置中移动和重新调整窗口大小的方法。这只是我的User32 JNA Windows库代码的一小部分：

    if (Desktop.isDesktopSupported()) 
    {
        Desktop.getDesktop().browse(URI.create(URL));
    }

导入java.awt.GridLayout；
导入java.awt.event.ActionEvent；
导入javax.swing.*；
导入com.sun.jna.Native；
导入com.sun.jna.Pointer；
导入com.sun.jna.win32.StdCallLibrary；
@抑制警告（“串行”）
公共类TestMoveWindow扩展了JPanel{
公共静态最终字符串[]边界_名称={“x”、“y”、“w”、“h”}；
私有JTextField windowNameField=新JTextField（15）；
私有JTextField[]boundsFields=新JTextField[BOUNDS_NAMES.length]；
公共TestMoveWindow（）{
JPanel winNamePanel=新的JPanel（）；
添加（新的JLabel（“窗口名：”）；
添加（windowNameField）；
JPanel boundsPanel=新的JPanel（新的网格布局（1,0,5,0））；
对于（int i=0；i

这需要在类路径上有jna库中的jna.jar和platform.jar。同样，这仅适用于Windows平台。代码的第一部分，TestMoveWindow只是一个测试GUI，用于演示程序如何工作，它实际上只不过是调用

JnaUtil.moveWindow（hWnd，x，y，w，h），但代码的“核心”是

import java.awt.event.ActionEvent;

import javax.swing.*;
