qt程序嵌入桌面（有鼠标事件）

 

//加头文件
#include <windows.h>
//函数声明：私有的
private:
static bool enumUserWindowsCB(HWND hwnd,LPARAM lParam); //静态全局函数
    HWND findDesktopIconWnd();
//函数实现
bool MainWindow::enumUserWindowsCB(HWND hwnd,LPARAM lParam)
{
    long wflags = GetWindowLong(hwnd, GWL_STYLE);
    if(!(wflags & WS_VISIBLE)) return TRUE;

    HWND sndWnd;
    if( !(sndWnd=FindWindowEx(hwnd, NULL, L"SHELLDLL_DefView", NULL)) ) return TRUE;
    HWND targetWnd;
    if( !(targetWnd=FindWindowEx(sndWnd, NULL, L"SysListView32", L"FolderView")) ) return TRUE;

    HWND* resultHwnd = (HWND*)lParam;
    *resultHwnd = targetWnd;
    return FALSE;
}


HWND MainWindow::findDesktopIconWnd()
{
    HWND resultHwnd = NULL;
    EnumWindows((WNDENUMPROC)enumUserWindowsCB, (LPARAM)&resultHwnd);
    return resultHwnd;
}
//函数调用
HWND desktopHwnd = findDesktopIconWnd();
    if(desktopHwnd)
        SetParent(this->winId(), desktopHwnd);
