I'm not sure what you're asking? Do you want to change the color of the currently highlighted item when you click it? Or do you want it to change when you press the button?

When I click an item in your code it changes the background color of that item, so aren't you already doing what you need?

[Melba23]

rrotx,

Take a look at my GUIListViewEx UDF (the link is in my sig) as that allows you to colour all the ListView items if required. Run Example 6: Use the "Save" and "Load" buttons to populate the RH ListView and then you can change the background colour of the selected item between blue and orange (obviously you could choose other colours if required).

rootx,

If you cannot be bothered to read about the UDF and correctly integrate it into your script, then it is hardly surprising that it does not work. I will see what I can do this evening.

Try this:

Melba, I read the word file, and the script 6, I have extracted the function I was thinking of using in my purpose, I have not much experience with listview mea culpa. Thx

[Melba23]

rootx,

No problem, it is a complex UDF to understand - it took even me a couple of goes to get it working!

For anyone wondering about the enigmatic code posted above, I received a PM stating:

Quote

when I try to use the keyboard .. UP DOWN arrow does not work, the images do not change anymore, it only works the click event

Now the code is in open forum I am looking at it.

A timely reminder that the Forum rules are quite clear about asking for help via PM - DO NOT DO IT!

rootx,

Looking at the code I see that you are using images within the ListView. My UDF does not cater for this and so there is no way it can be integrated into your script.

This is yet another example of a thread where the original question does not explain the full extent of the requirement, leading to a lot of wasted time as possible solutions are proposed which subsequently turn out to be far from what is actually  required. It is always a good idea to explain what is needed in as much detail as possible when starting a thread - then those who offer help can at least be sure that they are not wasting their time.

THX M23, your UDF works fine with the click event, and change the picture and color of the selected text line. My specific problem is when I use the keybinding $LVN_KEYDOWN.

So, I hope someone have one idea to solve or to show me where I must look in the Autoit Helpline Functions.

Thx you all

rootx,

I am really surprised to hear that you get the UDF to work with that ListView. I have looked a the code and I cannot see a problem - I will look again this afternoon after my Spanish lesson.

THX, I found this 4now https://msdn.microsoft.com/en-us/library/bb775483(v=vs.85).aspx

rootx,

That is what the UDF uses to do the colouring.

Hi guys I tried with the udf melba and even without it I can only using the click event, someone could explain to me why when I use $ LVN_KEYDOWN the image is not updated? Thank you.

Hello.... Is there someone who would have patience to help me,I tried with the udf melba and even without it I can only using the click event, someone could explain to me why when I use $ LVN_KEYDOWN the image is not updated?

THX.

[Melba23]

rootx,

Does no-one ever do any debugging of their own scripts nowadays? A few simple ConsoleWrites give the answer:

The reason the keys do not work is that the $itemc = _GUICtrlListView_GetSelectedIndices($hListView, False) line is returning nothing. As a result, the $iItemTextd = _GUICtrlListView_GetItemText($hListView, $itemc, 1) line always returns the same image path.

You will have to add some code to track which item is being selected by the keys rather than relying on the  _GUICtrlListView_GetSelectedIndices command. This is perhaps because my UDF is dealing with the colouring rather then leaving it to Windows - but do not hold your breath for me to amend it so that the command does return the correct value.

M23

Edit: You are in luck - the UDF should be able to do what you want and a new function is being prepared.

rootx,

This is working for me. Add this function to the end of your script:

; #FUNCTION# =========================================================================================================
; Name...........: _GUIListViewEx_GetLastSelectedItem
; Description ...: Get last selected item in active or specified ListView
; Syntax.........: _GUIListViewEx_GetLastSelectedItem($iLV_Index = 0)
; Parameters ....: $iLV_Index - Index of ListView as returned by _GUIListViewEx_Init
; Requirement(s).: v3.3.10 +
; Return values .: Success: Delimited string ListViewIndex|Row|Col
;                  Failure: Returns "" and sets @error as follows:
;                      1 = No ListView yet active or invalid index passed
;                      2 = No item selected in
; Author ........: Melba23
; Modified ......:
; Remarks .......: If multiple items are selected, only the last selected is returned
; Example........: Yes
;=====================================================================================================================
Func _GUIListViewEx_GetLastSelectedItem($iLV_Index = 0)

    ; Check valid index
    Switch $iLV_Index
        Case 1 To $aGLVEx_Data[0][0]
            ; Valid index
        Case Else
            ; Get active ListView
            $iLV_Index = _GUIListViewEx_GetActive()
            ; If no ListView active
            If $iLV_Index = 0 Then Return SetError(1, 0, "")
    EndSwitch

    ; Read last selected item
    Local $iRow = $aGLVEx_Data[$iLV_Index][20]
    Local $iCol = $aGLVEx_Data[$iLV_Index][21]
    ; Check selection has been made
    If $iRow = -1 Or $iCol = -1 Then Return SetError(2, 0, "")
    ; Return selection details
    Return $iLV_Index & "|" & $iRow & "|" & $iCol

EndFunc

Now amend the $LVN_KEYDOWN handler like this:

Case $LVN_KEYDOWN
                    $tInfo = DllStructCreate($tagNMLVKEYDOWN, $ilParam)
                    $iKey = DllStructGetData($tInfo, "VKey")
                    ; Get current selection
                    $aLastSel = StringSplit(_GUIListViewEx_GetLastSelectedItem(), "|")
                    Switch $iKey
                        Case 38
                            ; Move up unless at top
                            $iCurrItem = $aLastSel[2] - 1
                            If $iCurrItem < 0 Then
                                $iCurrItem = 0
                            EndIf
                            _GUICtrlListView_ClickItem($hWndFrom, $iCurrItem)
                        Case 40
                            ; Move down unless at bottom
                            $iCurrItem = $aLastSel[2] + 1
                            If $iCurrItem >= _GUICtrlListView_GetItemCount($hWndFrom) Then
                                $iCurrItem = _GUICtrlListView_GetItemCount($hWndFrom) - 1
                            EndIf
                            _GUICtrlListView_ClickItem($hWndFrom, $iCurrItem)
                    EndSwitch

And you can remove all the If $bChanged section from your idle loop as the handler clicking on the item sets of another pass through the handler as if you had used the mouse.

As I said, it works for me - does it for you?
