I present to your attention an alternative version of the window dividers CtrlSplitter. The Static element is used as a splitter separator, and the functioning of the separators is fully implemented in their window procedure. Example.au3 CtrlSplitNotify.au3 CtrlSplit.au3 ApiDPI.au3

Thanks for your help. I got it. because i download the file "node-autoit-opencv-com-2.8.0.zip" i think it is sample and all of files. So i can not found it.

Hello. I was trying your penultimate script above and could improve it a bit (no more Adib but $HDN_ENDTRACK changed to $HDN_ITEMCHANGED, added _GUICtrlHeader_Destroy) etc... The problem with a separate header control is that you'll have to add plenty of code in your script to get (nearly) the same results as a native Listview control (which takes care of its native header items), this means sorting listview columns by clicking their headers, changing header items order by dragging a header item at the left or right of another, double-clicking a header separator etc...) For example, in my script below, please notice what will happen when you enlarge a header item : an horizontal scrollbar will appear in the listview. Now when you scroll horizontally, the headers items won't align the listview columns, so you'll have to take care of this part too etc... Of course all these points could be fixed with additional code, it's up to you to decide if you're ready to add all this code to avoid flicker. #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <GuiListView.au3> ; DPI DllCall("User32.dll", "bool", "SetProcessDpiAwarenessContext" , "HWND", "DPI_AWARENESS_CONTEXT" -2) Opt("MustDeclareVars", 1) ;0=no, 1=require pre-declaration Global $g_hGUI, $g_hChild Global $g_hHeader, $g_idListview Example() Func Example() $g_hGUI = GUICreate("Example", 400, 400, -1, -1, $WS_OVERLAPPEDWINDOW, $WS_EX_COMPOSITED) GUISetBkColor(0x202020) GUISetState(@SW_SHOW, $g_hGUI) $g_hChild = GUICreate("ChildWindow", 320, 320, 40, 40, $WS_CHILD, -1, $g_hGUI) GUISetBkColor(0x606060) $g_hHeader = _GUICtrlHeader_Create($g_hChild) _GUICtrlHeader_AddItem($g_hHeader, "Column1", 100) _GUICtrlHeader_AddItem($g_hHeader, "Column2", 100) _GUICtrlHeader_AddItem($g_hHeader, "Column3", 100) $g_idListview = GUICtrlCreateListView("col1|col2|col3 ", 0, 24, 320, 295, BitOR($GUI_SS_DEFAULT_LISTVIEW, $LVS_NOCOLUMNHEADER), BitOR($LVS_EX_DOUBLEBUFFER, $LVS_EX_FULLROWSELECT)) For $i = 1 To 30 GUICtrlCreateListViewItem("item" & $i & "|item" & $i & "|item" & $i, $g_idListview) Next ; resize listview columns to match header widths _resizeLVCols() GUISetState(@SW_SHOW, $g_hChild) ; get rid of dotted rectangle on listview, when an item got the focus GUICtrlSendMsg($g_idListview, $WM_CHANGEUISTATE, 65537, 0) GUIRegisterMsg($WM_NOTIFY, WM_NOTIFY) While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop EndSwitch WEnd _GUICtrlHeader_Destroy($g_hHeader) ; added GUIDelete($g_hChild) GUIDelete($g_hGUI) EndFunc ;==>Example Func _resizeLVCols() For $i = 0 To _GUICtrlHeader_GetItemCount($g_hHeader) - 1 _GUICtrlListView_SetColumnWidth($g_idListview, $i, _GUICtrlHeader_GetItemWidth($g_hHeader, $i)) Next EndFunc ;==>_resizeLVCols Func WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam) #forceref $hWnd, $iMsg, $wParam Local $tNMHDR = DllStructCreate($tagNMHDR, $lParam) Local $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) Local $iCode = DllStructGetData($tNMHDR, "Code") Switch $hWndFrom Case $g_hHeader Switch $iCode Case $HDN_ITEMCHANGED, $HDN_ITEMCHANGEDW _resizeLVCols() EndSwitch EndSwitch Return $GUI_RUNDEFMSG EndFunc ;==>WM_NOTIFY
