[已解决]使用_AddArray 做成的 ListView 如何用 _SortItems来排序??

本帖最后由 kk_lee69 于 2012-8-24 21:37 编辑

使用_GUICtrlListView_AddArray 做成的 ListView 如何用 _GUICtrlListView_SortItems來排序??

如下例子....

已經研究出來.....感謝 athland5013 兄大力的幫忙.....

結論是系統原生自帶的 _GUICtrlListView_AddArray在加入 LISTVIEW 的過程中....沒有加入 Param
而 GUICtrlListView_Sort是排序的主体,再看看他工作原理,是要 DllStructSetData($tInfo, "Param", $nItem1)
所以 LISTVIEW沒有 Param就無法排序.....所以在 athland5013 兄的幫忙下改了原本的 _GUICtrlListView_AddArray

換個名子.....當然要用的時候可以直接加在主程式裡面不過不要忘記 #include <GuiListView.au3>

代碼如下:....

Func _ListViewAddArray($hWnd, ByRef $aItems)
If $Debug_LV Then __UDF_ValidateClassName($hWnd, $__LISTVIEWCONSTANT_ClassName)

Local $fUnicode = _GUICtrlListView_GetUnicodeFormat($hWnd)

Local $tItem = DllStructCreate($tagLVITEM)
Local $pItem = DllStructGetPtr($tItem)
Local $tBuffer
If $fUnicode Then
$tBuffer = DllStructCreate("wchar Text")
Else
$tBuffer = DllStructCreate("char Text")
EndIf
Local $pBuffer = DllStructGetPtr($tBuffer)

DllStructSetData($tItem, "Text", $pBuffer)
DllStructSetData($tItem, "TextMax", 4096)
Local $iLastItem = _GUICtrlListView_GetItemCount($hWnd)
_GUICtrlListView_BeginUpdate($hWnd)
If IsHWnd($hWnd) Then
If _WinAPI_InProcess($hWnd, $_lv_ghLastWnd) Then
For $iI = 0 To UBound($aItems) - 1
DllStructSetData($tItem, "Mask", BitOR($LVIF_TEXT, $LVIF_PARAM))
DllStructSetData($tItem, "Param",$iLastItem + $iI)

DllStructSetData($tItem, "Item", $iI)
DllStructSetData($tItem, "SubItem", 0)
DllStructSetData($tBuffer, "Text", $aItems[$iI])
GUICtrlSendMsg($hWnd, $LVM_INSERTITEMW, 0, $pItem)

DllStructSetData($tItem, "Mask", $LVIF_TEXT)
For $iJ = 1 To UBound($aItems, 2) - 1
DllStructSetData($tItem, "Mask", BitOR($LVIF_TEXT))
DllStructSetData($tItem, "SubItem", $iJ)
DllStructSetData($tBuffer, "Text", $aItems[$iI][$iJ])
GUICtrlSendMsg($hWnd, $LVM_SETITEMW, 0, $pItem)
Next
Next

DllStructSetData($tItem, "Item", $iI + $iLastItem)
DllStructSetData($tItem, "SubItem", 0)

EndIf
For $iJ = 1 To UBound($aItems, 2) - 1
DllStructSetData($tItem, "SubItem", $iJ)
DllStructSetData($tBuffer, "Text", $aItems[$iI][$iJ])
_MemWrite($tMemMap, $pItem, $pMemory, $iItem)
_MemWrite($tMemMap, $pBuffer, $pText, $iBuffer)
If $fUnicode Then
GUICtrlSendMsg($hWnd, $LVM_SETITEMW, 0, $pMemory)
Else
GUICtrlSendMsg($hWnd, $LVM_SETITEMA, 0, $pMemory)
EndIf
Next
Next
_MemFree($tMemMap)
EndIf
Else
For $iI = 0 To UBound($aItems) - 1
DllStructSetData($tItem, "Mask", BitOR($LVIF_TEXT, $LVIF_PARAM))
DllStructSetData($tItem, "Param",$iLastItem + $iI)
DllStructSetData($tItem, "Item", $iI + $iLastItem)

兄弟,都说了原版自带的<GuiListView.au3>里面 AddArray不能用SortItems排序的,需要修改一下的

你试试用AddItem,AddsubItem函数就可以排序,~~~~~~~~~~原因是:

你打开<GuiListView.au3>仔细看一下AddItem,AddsubItem,AddArray,SortItems,_RegisterSortCallBack,__GUICtrlListView_Sort里面的工作原理,你了解了就会明白 AddArray添加的item为什么在SortItems时不工作了

关键词:Param

另外在ListView排序是很慢的,如果上千上万条你会砸机的,还不如在sql里面干脆~~~~

我知道你回過我

但_GUICtrlListView_AddArray不能用_GUICtrlListView_SortItems排序
要排序需要
修改 DllStructSetData($tItem, "Mask", BitOR($LVIF_TEXT, $LVIF_PARAM))
添加 DllStructSetData($tItem, "Param", _SendMessage($hWnd, $LVM_GETITEMCOUNT) + 11111111)

但是這段話我琢磨了好久....也改了很多地方....就沒成功的....

老實說我的功力不夠我看了他們的工作原理但是對於DllStructSetData 這樣的東西老實說看不懂.....P.S 本身不是寫程式出身的

所以只能用錯誤嘗試法....將您的提示改在我認為的地方....但是老是不行.....所以又上來提問的 .....感謝回覆

在LISTVIEW 排序在某些情況下還是會用到所以想研究出來看看如何改的

把你修改的_GUICtrlListView_AddArray贴来看看,我跟你再探讨一下,授鱼不如授渔嘛

还有论坛某位大师说过,了解UDF的工作原理对你的提高有莫大的帮助

感謝 !!

因為您提到了修改所以我找到了 DllStructSetData($tItem, "Mask", $LVIF_TEXT) 改成了
DllStructSetData($tItem, "Mask", BitOR($LVIF_TEXT, $LVIF_PARAM)) 再加上一行
DllStructSetData($tItem, "Param", _SendMessage($hWnd, $LVM_GETITEMCOUNT) + 11111111)
但是畫面就會只剩下第一行然後其他的都不見了....

中午码了几百字, 提交时论坛居然宕机了, 气死~~~~~~~~

;
For $iI = 0 To UBound($aItems) - 1

;DllStructSetData($tItem, "Param", _SendMessage($hWnd, $LVM_GETITEMCOUNT) + 11111111)
;应该加在这里24-28行之间,放在你那位置Param值是相同的,所以只有一行,因为Param要求是唯一的
;然而上面有一句 $iLastItem = _GUICtrlListView_GetItemCount($hWnd) 等同于 _SendMessage($hWnd, $LVM_GETITEMCOUNT)
;所以写成以下就可以了
DllStructSetData($tItem, "Param", $iLastItem + $iI);你可以在 $iI后面再加大数值,效果一样,反正每个item的Param都不同就是了

DllStructSetData($tItem, "Item", $iI)
DllStructSetData($tItem, "SubItem", 0)
DllStructSetData($tBuffer, "Text", $aItems[$iI])
_SendMessage($hWnd, $LVM_INSERTITEMW, 0, $pItem, 0, "wparam", "ptr")
Next
;

;
;然后你会遇到另一个问题,subitem不出来了,仔细看一下AddItem,AddsubItem的工作原理,
;AddsubItem时Mask成员只有$LVIF_TEXT,不需要$LVIF_PARAM,而AddItem是需要的

_SendMessage($hWnd, $LVM_INSERTITEMW, 0, $pItem, 0, "wparam", "ptr")
;所以在28-29行之间加一句,把Mask修改为只有$LVIF_TEXT成员
DllStructSetData($tItem, "Mask", $LVIF_TEXT)

For $iJ = 1 To UBound($aItems, 2) - 1
Next
;

;
;因为上面的修改导致Mask成员改变,所以需要把你的第16行
;DllStructSetData($tItem, "Mask", BitOR($LVIF_TEXT, $LVIF_PARAM))
;移动到24-28行之间
;即
For $iI = 0 To UBound($aItems) - 1
DllStructSetData($tItem, "Mask", BitOR($LVIF_TEXT, $LVIF_PARAM))
DllStructSetData($tItem, "Param", $iLastItem + $iI)
DllStructSetData($tItem, "Item", $iI)
DllStructSetData($tItem, "SubItem", 0)
DllStructSetData($tBuffer, "Text", $aItems[$iI])
_SendMessage($hWnd, $LVM_INSERTITEMW, 0, $pItem, 0, "wparam", "ptr")

DllStructSetData($tItem, "Mask", $LVIF_TEXT)
For $iJ = 1 To UBound($aItems, 2) - 1
DllStructSetData($tItem, "SubItem", $iJ)
DllStructSetData($tBuffer, "Text", $aItems[$iI][$iJ])
_SendMessage($hWnd, $LVM_SETITEMW, 0, $pItem, 0, "wparam", "ptr")
Next
Next

;

;由于用于大量数据,
;For $iJ = 1 To UBound($aItems, 2) - 1
;这一行建议在AddArray开始时就定义为变量,假如10w条就要UBound()10w次,99999次是无用功啊
;在大量数据时_SendMessage要比GUICtrlSendMsg执行效率差,差很多很多~~~~

athland5013 发表于 2012-8-24 19:11:44

原理是RegisterSortCallBack函数注册了

DllCallbackRegister("__GUICtrlListView_Sort", "int", "int;int;hwnd") ; Handle of callback

GUICtrlListView_Sort是排序的主体,再看看他工作原理,是要

DllStructSetData($tInfo, "Param", $nItem1)

当你添加的item Mask成员没有Param,排序就不成功了

用AddItem,AddsubItem添加的item排序成功就是因为这个Param

详细查看一下$tagLVITEM数据结构,帮助里有

感謝您熱心的解說....這樣我就更多點了解它的運作原理..... 可是我剛剛測試了一下.....

從觀念上說你說的很仔細我也看懂了...但是實際上我改成您的方式的話一樣是無法使用 _SortItems 來排序...

而且照您所說的改成...

If IsHWnd($hWnd) Then
If _WinAPI_InProcess($hWnd, $_lv_ghLastWnd) Then
For $iI = 0 To UBound($aItems) - 1
DllStructSetData($tItem, "Mask", BitOR($LVIF_TEXT, $LVIF_PARAM))
DllStructSetData($tItem, "Param",$iLastItem + $iI)

DllStructSetData($tItem, "Item", $iI)
DllStructSetData($tItem, "SubItem", 0)
DllStructSetData($tBuffer, "Text", $aItems[$iI])
_SendMessage($hWnd, $LVM_INSERTITEMW, 0, $pItem, 0, "wparam", "ptr")

DllStructSetData($tItem, "Mask", $LVIF_TEXT)
For $iJ = 1 To UBound($aItems, 2) - 1
DllStructSetData($tItem, "SubItem", $iJ)
DllStructSetData($tBuffer, "Text", $aItems[$iI][$iJ])
_SendMessage($hWnd, $LVM_SETITEMW, 0, $pItem, 0, "wparam", "ptr")
Next
Next

後反而所有的陣列內容都無法出現全部出現空白.......不知道哪裡出了問題
