Windows下获取窗口列表，会过滤一些无效窗口

一、Windows下获取到当前所有窗口的列表 1、获取桌面窗口，因为Windows上所有的窗口都是在桌面上面的，所有其他的窗口都是桌面窗口的子窗口 HWND desktop_window = GetDesktopWindow(); 2、获取子窗口 HWND window = GetWindow(desktop_window, GW_CHILD); 3、获取同级下一个窗口，因为所有的窗口都是桌面窗口的子窗口，所有接下来一直获取下一个窗口，一直到获取的窗口为NULL结束 window = GetNextWindow(window, GW_HWNDNEXT);  4、获取窗口的进程id DWORD process_id; GetWindowThreadProcessId(window, &process_id); 5、获取窗口大小 RECT rect; GetWindowRect(hwnd, &rect); 6、获取窗口的标题title char windowTitle[128] = ""; GetWindowTextA(window, windowTitle, 128);  7、获取窗口所对应的进程名 char name[128] = ""; HANDLE hProc = OpenProcess(PROCESS_QUERY_LIMITED_INFORMATION, false, process_id); GetProcessImageFileNameA(hProc, name, 128); CloseHandle(hProc); // 这里获取到的exe name会有路径信息，接下来我们把路径截掉 std::string exename = name; auto pos = exename.rfind("/"); if (pos == std::string::npos) { pos = exename.rfind("\"); } if (pos == std::string::npos) { return ""; } exename = exename.substr(pos + 1, window_name.length() - pos); 上面的代码已经完成了一个基本的窗口获取，打印输出一下，发现获取到的窗口非常的多，很多窗口都是我们不需要的，接下来对窗口做一些过滤  1、首先把exename为空的过滤掉 if(exename.empty()){ continue; } 2、过滤掉最小化的窗口，这个时候会过滤掉大部分的窗口，当然也可以不使用这个条件 if(!IsWindowVisible(window)) { continue; }  3、过滤掉window title为空的窗口，也可以根据窗口标题过滤掉一些特殊的窗口，比如：Microsoft Store和Microsoft Edge if(strlen(windowTitle) == 0) { continue; } 4、 过滤掉窗口大小为0的窗口 RECT rect; GetClientRect(window, &rect); if ((rect.bottom == 0 || rect.right == 0)) { continue; } 5、 过滤掉工具窗口，工具窗口不出现在任务条或用户按下ALT+TAB时出现的窗口中 DWORD ex_styles = (DWORD)GetWindowLongPtr(window, GWL_EXSTYLE); if (ex_styles & WS_EX_TOOLWINDOW) { continue; } 6、过滤掉一些不能应用于弹出式窗口风格，也就是带有WS_CHILD属性的窗口 DWORD styles = (DWORD)GetWindowLongPtr(window, GWL_STYLE); if (styles & WS_CHILD) { continue; }  三、全部代码 #include #include #include #include #include #include #include #include const uint32_t kBufferSize = 128; struct WindowInfo { HWND windowHwnd; std::string windowName; std::string windowTitle; uint32_t windowWidth; uint32_t windowHeight; }; bool CheckWindowValid(HWND window) { RECT rect; GetClientRect(window, &rect); if ((rect.bottom == 0 || rect.right == 0)) { return false; } DWORD ex_styles = (DWORD)GetWindowLongPtr(window, GWL_EXSTYLE); if (ex_styles & WS_EX_TOOLWINDOW) { return false; } DWORD styles = (DWORD)GetWindowLongPtr(window, GWL_STYLE); if (styles & WS_CHILD) { return false; } if (!IsWindowVisible(window)) { return false; } return true; } bool CheckWindowTitleValid(char* windowName) { char storeName[] = "Microsoft Store"; if (strcmp(windowName, storeName) == 0) { return false; } char edgeName[] = "Microsoft Edge"; if (strcmp(windowName, edgeName) == 0) { return false; } if (strlen(windowName) == 0) { return false; } return true; } std::string GetWindowName(HWND window, DWORD process_id) { char exename[kBufferSize] = ""; HANDLE hProc = OpenProcess(PROCESS_QUERY_LIMITED_INFORMATION, false, process_id); GetProcessImageFileNameA(hProc, exename, 128); CloseHandle(hProc); std::string window_name = exename; auto pos = window_name.rfind("/"); if (pos == std::string::npos) { pos = window_name.rfind("\"); } if (pos == std::string::npos) { return ""; } return window_name.substr(pos + 1, window_name.length() - pos); } void GetWindowList() { HWND default_window = GetDesktopWindow(); char windowTitle[kBufferSize] = ""; std::string exename = ""; HWND window = GetWindow(default_window, GW_CHILD); while (window) { DWORD process_id; GetWindowThreadProcessId(window, &process_id); RECT rect; GetWindowRect(window, &rect); GetWindowTextA(window, windowTitle, 128); exename = GetWindowName(window, process_id); if (exename.empty() || !CheckWindowValid(window)) { break; } break; } while (window != NULL) { window = GetNextWindow(window, GW_HWNDNEXT); DWORD process_id; GetWindowThreadProcessId(window, &process_id); RECT rect; GetWindowRect(window, &rect); GetWindowTextA(window, windowTitle, 128); exename = GetWindowName(window, process_id); if (exename.empty() || !CheckWindowValid(window) || !CheckWindowTitleValid(windowTitle)) { continue; } std::cout << "windowTitle:" << windowTitle << std::endl; std::cout << "exename:" << exename << std::endl; } } int main(void) { GetWindowList(); getchar(); return 0; }
