GuilistviewEx Detect selected item in list view

[bourny]

Hi,

 

I am using Melba23`s UDF for my list view controls.  I am having difficulty trying to work out how to detect the item on the list view under the selection.  So far I can edit the UDF itself to give me an output of the array if I left or right click but I cannot isolate the item that is actually selected.

Here is what I have edited in the UDF however I do not want to edit the udf itself as this is unwise and I would rather call Melba23`s functions to return the information I need.

 

Here is the UDF code I have been playing with but again this this not what I want to do editing the UDF.

    #forceref $hWnd, $iMsg, $wParam

    ; Struct = $tagNMHDR and "int Item;int SubItem" from $tagNMLISTVIEW
    Local $tStruct = DllStructCreate("hwnd;uint_ptr;int_ptr;int;int", $lParam)
    If @error Then Return

    ; Check if enabled ListView or header
    For $iLV_Index = 1 To $aGLVEx_Data[0][0]
        If $aGLVEx_Data[$iLV_Index][0] = DllStructGetData($tStruct, 1) Then
            ExitLoop
        EndIf
    Next
    If $iLV_Index > $aGLVEx_Data[0][0] Then Return ; Not enabled

    Local $iCode = BitAND(DllStructGetData($tStruct, 3), 0xFFFFFFFF)
    Switch $iCode


       Case $NM_RCLICK



         ; Set values for active ListView
            $aGLVEx_Data[0][1] = $iLV_Index

            ; Get and store item index
            $aGLVEx_Data[0][4] = DllStructGetData($tStruct, 4)

            If IsArray($aGLVEx_Data[$iLV_Index][4]) Then
               ; Load array
               $aGLVEx_SrcArray = $aGLVEx_Data[$iLV_Index][2]
               ; Load current ListView sort state array
              ; Local $aLVSortState = $aGLVEx_Data[$iLV_Index][4]

              ; $aGLVEx_Data[$iLV_Index][4] = $aLVSortState
               ; Reread listview items into array
               Local $iDim2 = UBound($aGLVEx_SrcArray, 2) - 1
               For $j = 1 To $aGLVEx_SrcArray[0][0]
                   For $k = 0 To $iDim2

                      $H = _GUICtrlListView_GetItemText($hGLVEx_SrcHandle, $j - 1, $k)
                       $aGLVEx_SrcArray[$j][$k] = $H
                      msgbox(0, "", $H)
                   Next


               Next

               ;_ArrayDisplay($aGLVEx_SrcArray)

               ; Store amended array
               $aGLVEx_Data[$iLV_Index][2] = $aGLVEx_SrcArray
               ; Delete array
               $aGLVEx_SrcArray = 0
           EndIf

         ; Create Local array for checkboxes (if no checkboxes makes no difference)
         ; Create Local array for checkboxes (if no checkboxes makes no difference)
         ConsoleWrite("An Item Was clicked with the left mouse button" & @crlf)



       Case $NM_CLICK
            ConsoleWrite("An Item Was clicked with the left mouse button" & @crlf)

Have a look at

_GUICtrlListView_GetSelectedIndices

[bourny]

Thanks .... 

 

I found it also and managed to embed a function into Melba23`s UDP to pass through the indices to allow me to simply loop through the list view with a counter that displays the item once the counter matches the indices.

 

 

Func _GUIListViewEx_WM_NOTIFY_Handler($hWnd, $iMsg, $wParam, $lParam)

    #forceref $hWnd, $iMsg, $wParam

    ; Struct = $tagNMHDR and "int Item;int SubItem" from $tagNMLISTVIEW
    Local $tStruct = DllStructCreate("hwnd;uint_ptr;int_ptr;int;int", $lParam)
    If @error Then Return

    ; Check if enabled ListView or header
    For $iLV_Index = 1 To $aGLVEx_Data[0][0]
        If $aGLVEx_Data[$iLV_Index][0] = DllStructGetData($tStruct, 1) Then
            ExitLoop
        EndIf
    Next
    If $iLV_Index > $aGLVEx_Data[0][0] Then Return ; Not enabled

    Local $iCode = BitAND(DllStructGetData($tStruct, 3), 0xFFFFFFFF)
    Switch $iCode


       Case $NM_RCLICK

         $iIndex = _GUICtrlListView_GetSelectedIndices($hListView_Right)
         ShowRightClickedItem($iIndex)

         ConsoleWrite("An Item Was clicked with the left mouse button" & @crlf)



       Case $NM_CLICK
            ConsoleWrite("An Item Was clicked with the left mouse button" & @crlf)

From reading 'A Beginner’s Guide To Melba23’s GUIListViewEx UDF'

it seems not neccesary to edit the UDF

Here i'm trying an example:
