學Python沒多久第一次用ctypes 結果弄了好幾天還是沒辦法要怎麼抓像vista下的檔案總管裡面的圖示資訊呢我可以確定的是我有找到windows的handle和他下面的listview的handle (他的classname是SysListView32) 一些不需要傳struct的好像都是ok的 n_item = SendMessage(hList, LVM_GETITEMCOUNT, 0, 0) 和 SendMessage(hList, LVM_SETHOTITEM, 3, 0) 都是ok的然後我想使用的是LVM_FINDITEM和LVM_GETITEM 不過可能是我struct的地方寫爛掉了常常回傳的值都不一樣多試次幾還會當掉 (Windows檔案總管已經停止運作) 下面是我寫的code 不知道哪邊有問題呢網路上找不太到用python要抓listview資訊的code class POINT(ctypes.Structure): _fields_ = [ ("x", ctypes.c_int), ("y", ctypes.c_int)] class LVFINDINFO(ctypes.Structure): _fields_ = [ ("flags", ctypes.c_uint), ("psz", ctypes.c_char_p), ("lParam", ctypes.c_int), ("pt", POINT), ("vkDirection", ctypes.c_uint)] class _LVITEM(ctypes.Structure): _fields_ = [ ("mask", ctypes.c_uint), ("iItem", ctypes.c_int), ("iSubItem", ctypes.c_int), ("state", ctypes.c_uint), ("stateMask", ctypes.c_uint), ("pszText", ctypes.c_char_p), ("cchTextmax", ctypes.c_int), ("iImage", ctypes.c_int), ("lParam", ctypes.c_int), ("iIndent", ctypes.c_int), ("iGroupId", ctypes.c_int), ("cColumns", ctypes.c_uint), ("puColumns", ctypes.POINTER(ctypes.c_uint)), ("piColFmt", ctypes.POINTER(ctypes.c_int)), ("iGroup", ctypes.c_int)] def getItem(hList, n): s_item = _LVITEM() s_item.mask = LVIF_TEXT s_item.pszText = ctypes.c_char_p('A' * 1024) s_item.iItem = n s_item.cchTextmax = 1024 tmp1 = ctypes.c_uint(0) tmp2 = ctypes.c_int(0) s_item.puColumns = ctypes.pointer(tmp1) s_item.piColFmt = ctypes.pointer(tmp2) print 'SendMessage = %d' % SendMessage(hList, LVM_GETITEMA, 0, ctypes.byref(s_item)) return s_item def findItem(hList, string): s_info = LVFINDINFO() s_info.flags = LVFI_NEARESTXY s_info.vkDirection = VK_HOME s_info.psz = ctypes.c_char_p(string) #s_info.lParam = 0 s_info.pt.x = 1291 s_info.pt.y = 297 print s_info print s_info.flags print s_info.psz print s_info.lParam print s_info.pt.x, s_info.pt.y print s_info.vkDirection print n_find = SendMessage(hList, LVM_FINDITEMA, -1, ctypes.byref(s_info)) return n_find 學Python沒多久上面也是自己寫的如果有些用法或觀念不正確也請多指正謝謝還有用win32api的話會比較方便嗎因為它好像也沒有listview的相關函式 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.30.36
