窗口层次结构
EnumWindows: 枚举系统中的所有顶层窗口,并将句柄传递给回调函数。
EnumWindows(EnumWindowsProc, 0); BOOL CALLBACK EnumWindowsProc(HWND hwnd, LPARAM lparam) { TCHAR szTitleName[0xFF] = { 0 }; TCHAR szClassName[0xFF] = { 0 }; GetWindowText(hwnd, szTitleName, 0xFF); GetClassName(hwnd, szClassName, 0xFF); printf("顶层窗口句柄 -> %p 标题 -> %ws 类名 -> %ws \r\n", hwnd, szTitleName, szClassName); return TRUE; }
EnumChildWindows: 枚举指定父窗口的所有子窗口,并将句柄传递给回调函数。
EnumChildWindows(hwndMain, EnumChildWindowsProc, 0); BOOL CALLBACK EnumChildWindowsProc(HWND hwnd, LPARAM lparam) { TCHAR szTitleName[0xFF] = { 0 }; TCHAR szClassName[0xFF] = { 0 }; GetWindowText(hwnd, szTitleName, 0xFF); GetClassName(hwnd, szClassName, 0xFF); printf("子窗口句柄 -> %p 标题 -> %ws 类名 -> %ws \r\n", hwnd, szTitleName, szClassName); return TRUE; }
窗口状态和属性
- 有效性检查 (
IsWindow
):任何操作之前,必须首先确定窗口句柄是否有效。 - 可见性检查 (
IsWindowVisible
):决定窗口是否显示在屏幕上。 - 启用/禁用窗口 (
EnableWindow
):控制用户对窗口的交互能力。 - 状态检查 (
IsIconic
/IsZoomed
):确定窗口当前是否处于最小化或最大化状态。 -
