找不到Java JNA sendMessage()

Question

我正在尝试使用JNA (概述)在最小化时将消息发送到应用程序或不在顶部(例如鼠标单击),并且我发现人们正在使用com.sun.jna.platform.win32.User32.SendMessage A(hW,0x0201,0,0);

但我在这堂课中找不到这个功能.

如果我做错了,有人可以给我一个如何实现它的例子吗？

码:

User32 user32;
Pointer hW = user32.GetForegroundWindow().getPointer();
user32.SendMessageA( hW, 0x0201, 0, 0 );

Answer 1

public interface User32Ext extends User32 {
User32Ext USER32EXT = (User32Ext) Native.loadLibrary("user32",

        User32Ext.class, W32APIOptions.DEFAULT_OPTIONS);

HWND FindWindowEx(HWND lpParent, HWND lpChild, String lpClassName,
        String lpWindowName);

HWND GetTopWindow(HWND hwnd);

HWND GetParent(HWND hwnd);

HWND GetDesktopWindow();

int SendMessage(HWND hWnd, int dwFlags, byte bVk, int dwExtraInfo);

int SendMessage(HWND hWnd, int Msg, int wParam, String lParam);

void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

void SwitchToThisWindow(HWND hWnd, boolean fAltTab);

}
