GUIListViewEx - BugFix Version 6 Apr 24

[jazzyjeff]

Wow, thanks Melba for your diligent work on this. It's much appreciated!

[Melba23]

jazzyjeff,

I think I have it sorted - this beta version works with the code you posted:

Can you please check it out and confirm that it works for you too.

It works great! Thanks very much. I have the array display and I am then able to edit the cells, where as before I had to have the _arraydisplay line commented out.

[Melba23]

jazzyjeff,

Great - I will release a new version soon. Thanks for finding that obscure bug in the UDF - not some thing I had ever thought of testing!

[NEW VERSION] - 20 Sep 17

Changed:

• An obscure AutoIt "feature" that I discovered some years ago meant that if you had deleted a GUI created by your script and had 2 or more GUIs still present AutoIt would reset the "current" GUI for control creation to a null handle, because it cannot know which GUI the user wishes to use. This meant that when this UDF tried to create the temporary controls used for editing AutoIt no longer knew in which GUI to do so and so nothing happened. The UDF now forces the GUI holding the active ListView to be the "current" GUI for control creation. Thanks to jazzyjeff for reporting the problem.
• A couple of minor changes to prevent edge case failures.

New zip containing UDF, examples and guide in the first post.

HurleyShanabarger,

You need to set the ListView to use user header colours (add 16 to $iAdded when initialising) and set the required combo data in the $aHdrData array. Open example 6 and make the following changes:

Line #49

$iLVIndex_1 = _GUIListViewEx_Init($cLV_1, $aLVArray_1, 0, 0, True, 1 + 8 + 32 + 16) ; 16 added

Lines #63-73

; Set header data
Global $aHdrData[][] = [["Tom",               "Dick",              "Harry",           "Fred"], _                ; As colour is enabled, these will replace original titles
                         ["0xFF8080;0x8888FF", "0xFEFEFE;0x000000", "",                "0xFFFF00;0x00FF80"], _  ; Col 2 will use default colours
                         ["",                  "",                  @TAB & "H1|H2|H3", ""], _                   ; Col 2 readonly combo; Col 1 & 3 text
                         [0,                   0,                   100,               0]]                      ; Col 2 not resizeable - fixed 100 pixel width

;Global $aHdrData[][] = [[Default, "", "",  ""], _
;                       ["", Default, "",  ""], _
;                       ["", "", "",  Default], _
;                       [0,  0,  Default, 0]]
_GUIListViewEx_LoadHdrData($iLVIndex_1, $aHdrData)

; basically replacing the simple header with something a little more complex

Let me know if you still have problems.

M23

Hi Melba,

the "combo in a header" function you mentioned let me to think that there whould be actually a combobox in the header with a dropdown option, but I guess that is not what you meant, right?

 

/Edit: have you come across a way to always show a vertical/horizontal scrollbar in a listview, even though there is nothing to scroll?

That is exactly what I meant - you get a dropdown combo in the header. Run this and Ctrl-Click on "Harry":

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

#include "GUIListViewEx.au3"

Global  $iYellow = "0xFFFF00", _
        $iLtBlue = "0xCCCCFF", _
        $iGreen = "0x00FF00", _
        $iBlack = "0x000000", _
        $iRed = "0xFF0000", _
        $iBlue = "0x0000FF", _
        $iWhite = "0xFFFFFF"

Global $sRet

$hGUI = GUICreate("Combo Header ListView Example", 1000, 510)

; Create ListView
$cLV_1 = GUICtrlCreateListView("Zero Column|One Column|Two Column|Three Column", 10, 30, 480, 260, BitOR($LVS_SINGLESEL, $LVS_SHOWSELALWAYS))

_GUICtrlListView_SetExtendedListViewStyle($cLV_1, BitOR($LVS_EX_FULLROWSELECT, $LVS_EX_HEADERDRAGDROP))
For $i = 0 To 3
    _GUICtrlListView_SetColumnWidth($cLV_1, $i, 100)
Next

; Create array and fill listview
Global $aLVArray_1[6][4]
For $i = 0 To 5
    $sData = "Item " & $i & "-0"
    $aLVArray_1[$i][0] = $sData
    For $j = 1 To 3
        $sData &= "|SubItem " & $i & "-" & $j
        $aLVArray_1[$i][$j] = "SubItem " & $i & "-" & $j
    Next
    GUICtrlCreateListViewItem($sData, $cLV_1)
Next

; Initiate ListView = sort on column click - editable headers - header colours - user colours
$iLVIndex_1 = _GUIListViewEx_Init($cLV_1, $aLVArray_1, 0, 0, True, 1 + 8 + 16 + 32)

; Set column edit status
_GUIListViewEx_SetEditStatus($iLVIndex_1, "*")                   ; Default = standard text edit


; Set header data
Global $aHdrData[][] = [["Tom", "Dick", "Harry",           "Fred"], _   ; As colour is enabled, these will replace original titles
                         ["",   "",     "",                ""], _       ; Default colours
                         ["",   "",     @TAB & "H1|H2|H3", ""], _       ; Col 2 readonly combo; Col 0, 1 & 3 text
                         [0,    0,      0,                 0]]          ; All cols resizeable

_GUIListViewEx_LoadHdrData($iLVIndex_1, $aHdrData)

$cExit = GUICtrlCreateButton("Exit", 880, 470, 110, 30)

; If colours used then this function must be run BEFORE GUISetState
_GUIListViewEx_MsgRegister()

GUISetState()

While 1

    $iMsg = GUIGetMsg()
    Switch $iMsg
        Case $GUI_EVENT_CLOSE, $cExit
            Exit

    EndSwitch

    _GUIListViewEx_EventMonitor()

WEnd

You should see a read-only combo appear with the 3 options which can be selected and then appear as the new header title.

(4021) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
$aItemData[$i] = $aGLVEx_SrcArray[$iGLVEx_DraggedIndex + 1][$i]
$aItemData[$i] = ^ ERROR

i get this error when using drag&drop in my own code. Seems to work fine in your examples tho, is it a buggy or am i missing out something? both srcArray and Draggedindex have no values in them. 

 

The only UDF-Functions i used are 

    $hLVL = _GUIListViewEx_Init($hList)
    _GUIListViewEx_SetEditStatus($hLVL, "*")

c0w,

Welcome to the AutoIt forums.

Seems to work fine in your examples

So it is likely to be your code that is causing the problem. Please post it so I can take a look - see here how to do it.

EndFunc   ;==>InitListviewEx

Hey, thanks for the ultra fast response

i wrote the function above and simply called it after gui creation.

The listbox is created by 

$List1 = GUICtrlCreateListView("X|Y|Shift|Ctrl|Right|Alt|Sleep", 238, 64, 330, 180)

And filled by this function:

Func _addCoord()
    
    $shiftState = GUICtrlRead($chkHoldShift)
    If $shiftState = 4 Then $shiftState = 0

    $CTRLState = GUICtrlRead($chkHoldCTRL)
    If $CTRLState = 4 Then $CTRLState = 0

    $RclickState = GUICtrlRead($chkRightClick)
    If $RclickState = 4 Then $RclickState = 0

    $altState = GUICtrlRead($chkHoldalt)
    If $altState = 4 Then $altState = 0

    _GUICtrlListView_AddItem($List1, MouseGetPos(0))
    _GUICtrlListView_AddSubItem($List1, _GUICtrlListView_GetItemCount($List1) - 1, MouseGetPos(1), 1)
    _GUICtrlListView_AddSubItem($List1, _GUICtrlListView_GetItemCount($List1) - 1, $shiftState, 2)
    _GUICtrlListView_AddSubItem($List1, _GUICtrlListView_GetItemCount($List1) - 1, $CTRLState, 3)
    _GUICtrlListView_AddSubItem($List1, _GUICtrlListView_GetItemCount($List1) - 1, $RclickState, 4)
    _GUICtrlListView_AddSubItem($List1, _GUICtrlListView_GetItemCount($List1) - 1, $altState, 5)
    _GUICtrlListView_AddSubItem($List1, _GUICtrlListView_GetItemCount($List1) - 1, GUICtrlRead($inp_WaitAfterClick), 6)
EndFunc   ;==>_addCoord

actually i got 3 listboxes and can be filled in different ways. but it doesnt matter, in most of my tries it crashes. But im having a hard time to read through your code to find where the parameters come from and why they would be empty

[Melba23]

c0w,

Please post some runnable code - just posting a few snippets is not going to help me much. I do not need all of the 7000+ lines you no doubt have, just enough to show the problem - which I suspect is because you have not used the _GUIListViewEx_MsgRegister function so that the UDF can do its magic. If I write my own code it will not have errors (I hope) - so you coding a basic GUI and ListView which does not drag/drop will suffice.

M23

 

[c0w]

Urgh, its hard to pick stuff out of my code to make it small but runnable tbh. i added the  _GUIListViewEx_MsgRegister () right before the guisetstate command.

am i right with adding  _GUIListViewEx_MsgRegister () and then $hLVL = _GUIListViewEx_Init($hList) should enable the drag and drop? so i can maybe debug that myself

 

thanks for the help man

[Melba23]

c0w,

It may work, it may not - unless you let me have a runnable script so that I can debug, I really cannot say.

I do notice that in the snippets you posted above you are not using the UDF functions to fill your ListView. Once you have initialised your empty ListView (which you last post suggests is what you are doing) than if you do not use the UDF functions (_GUIListViewEx_Insert or _GUIListViewEx_InsertSpec) to add items then the UDF does not recognise them - which once again could give you the problem you are seeing.

Can you see why I need some runnable code so that I can help you? This is a complex UDF and you need to use it correctly to get it all working.

M23

[c0w]

well in my tests a saw a similiar outcome, when i did not use your functions to insert on drag and drop it loaded the old functions.  ill try to rewrite my script with your funcs and see if its still not working

[c0w]

Okay i tested it and got no change in behavior at all. I changed the code, that inserts data into the listview to 

$vData = MouseGetPos(0)&"|"&MouseGetPos(1)&"|"&$shiftState&"|"&$CTRLState&"|"&$RclickState&"|"&$altState&"|"&GUICtrlRead($inp_WaitAfterClick)
_GUIListViewEx_Insert($vData)

This works just fine, but on drag and drop its still crashes. I found a new info tho, when trying to drag the first item of the list somewhere else i get 

"I:\Autoit Workdir\1337ClickzBitBucket\GuiListViewEx.au3" (5216) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
$avArray[$iIndex] = $vInsert

If you want to take a deeper look at this at could send you the file per pm, but i dont wanna post it public.

[Melba23]

c0w,

By all means PM me the script.

[BUGFIX VERSION] - 25 Sep 17

Fixed:

A small bug which only appeared if you were continually emptying a ListView with _GUICtrlListView_DeleteAllItems, which means you need to use _GUIListViewEx_Close and then _GUIListViewEx_Init to reset the UDF. The closed handle was not being deleted correctly which meant that any actions on the reinitialised ListView were likely to fail as the UDF looked at the old data. Apologies.

New UDF in the first post.

M23

[Melba23]

Hi,

A quick word about the problem with c0w's script from a few posts above. As I suspected, he was not using the UDF to add/delete/etc items to the ListViews and so the UDF became confused. The UDF is very much an "all or nothing" affair - once you start using it, you must use it for everything associated with that ListView!

However, the debugging did throw up the issue I have just fixed, so thanks to c0w for that!
