自动化RPA开发 --获取所有窗口信息和进程信息

场景

准备做一个RPA工具，可以从桌面和浏览器选择元素，获取窗口信息和进程信息是必要的，因为获取了窗口信息和进程，可用对程序做一些想要的操作。

coding

工具类

/*** Windows系统工具类*/
public class WinOsUtils {static final User32 user32 = User32.INSTANCE;/*** 获取当前系统下所有的Windows窗口信息* @return*/public static List<WindowInfo> allWindows() {final List<WindowInfo> windows = new ArrayList<>();boolean result = user32.EnumWindows(new WinUser.WNDENUMPROC() {public boolean callback(final WinDef.HWND hwnd, final Pointer data) {if (user32.IsWindowVisible(hwnd)) {IntByReference windowPid = new IntByReference();user32.GetWindowThreadProcessId(hwnd, windowPid);String windowTitle = getWindowTitle(hwnd);windows.add(new WindowInfo(hwnd, windowPid.getValue(), windowTitle));}return true;}},null);/* Handle errors. */if (!result && Kernel32.INSTANCE.GetLastError() != 0) {throw new RuntimeException("Couldn't enumerate windows.");}/* Return the window list. */return windows;}/*** 过窗口句柄来获取指定窗口的标题文本，通常用于窗口管理、自动化测试、或需要识别和操作特定窗口的应用程序中。* @param hWnd 句柄* @return 窗口标题*/public static String getWindowTitle(WinDef.HWND hWnd) {char[] text = new char[1024];int length = user32.GetWindowText(hWnd, text, 1024);return length > 0 ? new String(text, 0, length) : null;}
}

窗口信息

/*** 窗口信息*/
public class WindowInfo {/*** 句柄 唯一定义APP的因素*/public WinDef.HWND hwnd;/*** 进程id*/public int pid;/*** 标题*/public String title;public WindowInfo(WinDef.HWND hwnd, int pid, String title) {super();this.hwnd = hwnd;this.pid = pid;this.title = title;}public WinDef.HWND getHwnd() {return hwnd;}public int getPid() {return pid;}public String getTitle() {return title;}
}

进程信息

/*** 系统进程信息* @Author: Herche Jane* @Date: 2023/10/16*/
public class ProcessInfo {/*** 进程名称*/private String name;/*** pid*/private Integer pid;public ProcessInfo(String name,Integer pid){this.name = name;this.pid = pid;}public String getName() {return name;}public Integer getPid() {return pid;}}

结束

这样我们获取了所有的窗口信息和进程信息了，后面有利于我们RPA软件的开发。
