GUIListViewEx - New Version 11Dec 24

Melba23 · December 11, 2016

robertocm,

I can reproduce the problem - looking into it.

M23

Edit: Found it and fixed it - closing ALL ListViews destroyed all the basic preset data along with the activated ListViews. The next release will work properly - my thanks for finding and reporting the problem.

if you want an immediate fix then replace this function:

Func _GUIListViewEx_Close($iLV_Index = 0)

    ; Check valid index
    If $iLV_Index < 0 Or $iLV_Index > $aGLVEx_Data[0][0] Then Return SetError(1, 0, 0)

    If $iLV_Index = 0 Then
        ; Remove all ListView data and reset count
        ReDim $aGLVEx_Data[1][UBound($aGLVEx_Data, 2)]
        $aGLVEx_Data[0][0] = 0
    Else
        ; Reset all data for ListView
        For $i = 1 To UBound($aGLVEx_Data, 2) - 1
            $aGLVEx_Data[$iLV_Index][$i] = 0
        Next

        ; Cancel active index if set to this ListView
        If $aGLVEx_Data[0][1] = $iLV_Index Then
            $aGLVEx_Data[0][1] = 0
        EndIf

    EndIf

    Return 1

EndFunc   ;==>_GUIListViewEx_Close

Dear Melba23,

In the test below i'm trying to load the data without a button: just typing any letter in the input box and press enter key. (this simulates a text to find in a field database)

Then I click one of the items, and press Backspace hotkey for editing.

But instead of editing, the focus seems to jump back to the input box.

ListView seems to lose the focus when pressing the hotkey first time after loading data in this way.

Many Thanks!

EDITED: amended following Accept Enter Key on input box , but same issue

Hi Melba,

I think a new issue.
In one of my apps, I populate the ListView from a ARRAY.

That worked fine. But as the array growth it does not look that nice. So I added _GUIListViewEx_BlockReDraw before the populate and set it to False after it.

But suddenly without further change the array got added in reverse order. I add the items with
_GUIListViewEx_Insert($aRetArray[$i])

_GUIListViewEx_SetActive($lvLV1_ExInit)
    Local $aRetArray
    _FileReadToArray($FileImport, $aRetArray)
;~  _GUIListViewEx_BlockReDraw($lvLV1_ExInit,True)
    If IsArray($aRetArray) Then
        For $i = 1 To $aRetArray[0]
            If $aRetArray[$i] <> "" Then _GUIListViewEx_Insert($aRetArray[$i])
        Next
    EndIf
;~  _GUIListViewEx_BlockReDraw($lvLV1_ExInit,False)

This gives me a LV like this:

01
02
03

In case I enable the BlockRedraw the Lv looks like this

03
02
01

Is it maybe that the _GUIListViewEx_Insert needs the redraw to select the new entry?

Could you confirm this behave? Of course I could reverse add the array, but I think that is not the target :-)

Melba23 · December 16, 2016

Sorry about the delay in replying - I am overseas dealing with the legal, financial and personal consequences of a family bereavement and my own impending move.

robertocm,

Found the problem - will be fixed in next release. Again my thanks for finding the bug.

Tankbuster,

Just use _GUIListViewEx_InsertSpec and force the insert to the final line - this works fine for me:

_GUIListViewEx_BlockReDraw($iLV,True)
For $i = 0 To UBound($aLV) - 1
    $sData = $aLV[$i][0]
    For $j = 1 To 3
        $sData &= "|SubItem " & $i & "-" & $j
    Next
    _GUIListViewEx_InsertSpec($iLV, -1, $sData)
Next
_GUIListViewEx_BlockReDraw($iLV,False)

Let me know of any more little problems you find - I will try and release a new version once I get home next week.

Dear Melba23,

In below test i'm trying to detect the index of highlighted item in the ListView following the steps from A Beginner’s Guide To Melba23’s GUIListViewEx UDF, namely:

set the relevant parameter of _GUIListViewEx_MsgRegister to False
call the relevant UDF handler function (_GUIListViewEx_WM_NOTIFY_Handler) from within your existing handler

All seems to work except for changing items: i can access to the edit mode, but seems not able to change the value when pressing enter key after editing some text.

Many Thanks,

robertocm,

You are trapping the {ENTER} key with the GUISetAccelerator call - so the UDF never sees it. I am not at all sure why you feel the need to use an Accelerator key here - why not just look for an event in the input like this?

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

Then you do not need the Accelerator key and {ENTER} works fine for editing:

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

#include "GUIListViewEx.au3"

$hGui = GUICreate("", 600, 350)

Global $aLV[6][4]
For $i = 0 To 5
    $sData = "Item " & $i & "-0"
    $aLV[$i][0] = $sData
    For $j = 1 To 3
        $sData &= "|SubItem " & $i & "-" & $j
        $aLV[$i][$j] = "SubItem " & $i & "-" & $j
    Next
Next

;Create ListView
$cLV = GUICtrlCreateListView("Zero Column|One Column|Two Column|Three Column", 2, 33, 580, 260, BitOR($LVS_SINGLESEL, $LVS_SHOWSELALWAYS))

Dear Melba23,

Using the Accelerator key was just based on a trial and error approach and also the result of copy-paste after reading a similar question in the forum, but without a clear understanding ...

Many Thanks! for your simple and perfect working solution.

p.s. Updated the example Phone Book at #138, page 7

Sturmi · January 27, 2017

HI @Melba23,

Any Idea how to get the Images from Listview back after a drag and drop event ? sadly getting removed after drag.

Melba23 · January 28, 2017

Sturmi,

I am afraid there is no support for images within the UDF, so I cannot offer any hints.

Melba23 · February 16, 2017

[NEW VERSION] - 16 Feb 17

Added:

Ability to use a user-defined sort function in place of the standard _ArraySort when sorting columns - see _GUIListViewEx_UserSort.

Changed:

More edit modes possible - now can have standard text, numeric values with an UpDown control, a combo (either editable or read-only), a date picker, or if all these are not enough a user-defined function. See the _SetEditStatus function header to see how these are set.
More options added to the _LoadHdrData function - but the size of the default array the function expects has increased as explained in the function header.
Detecting the various events within the ListView has become easier with the introduction of the _EventMonitor function. This is placed in the idle loop and allows the user to detect edit, drag/drop and sort events which may need action. Additionally the function checks for redrawing events (very important if the ListViews are coloured) and shows any tooltips initiated by the UDF. Check out the examples to see how you need to structure the function and interpret its returns.

The Guide file has been rewritten to explain all the new and amended functionalities - please take a moment to read through it as amending old scripts is not difficult but does require an understanding of what to change and how to change it.

New UDF, examples and Guide file in the zip in the first post.

Hi Melba,

how do I allow multi select on a multi columns listview. At least I found nothing in the rtf.

Eg. like in the example 6 the left one.

I would like to allow multi line select (with STRG key).

Is it possible or not with the UDF? (on single col LV it works...)

Tank

Melba23 · March 6, 2017

Tankbuster,

If you use the UDF to add colours within the ListView it is forced to single selection. So if you want multiple selections, you will have to remove all colour attributes.

M23

Tankbuster · March 7, 2017

Hi Melba,

thank you for the answer. Of course I will need both , colour and multi selection.... mmmh I need to think of eg separate listview next to the first one for the colorized output.
so it looks like one (and eg. hook the scroll to scroll both up and down)

Anyway, I appreciate what you did with the UDF so far.

Tank

powerofos · March 11, 2017

Hi Melba23,

listview with _GUIImageList_Create, i mean every rows with a define image, drag and drop function can use?

attach file for detail, thank you very much!

Best regards

powerofos,

As I explained only a few posts above, there is no support for images in the UDF - and I am afraid I have no intention of adding that functionality. Sorry.
