I want to edit a listview item

Martino · October 24, 2017

I have some problems with listview items.

in short
i create a Gui and a Listview
When i doubleclick an item i want to open an edit box where i can enter a new value.
When i click ok the gui is recreated.

But there seems to be a problem with the recreation of the gui and the Func WM_NOTIFY

Here below just a piece of my code but at this time i don't do anything with the newly entered project code.
But the list should be visible and when you double click it, the edit box should become visible and after that the gui should become visible again and you should be able again to double click an item so the editbox pops up again.
But it goes wrong the second time.

Anyone an idea?

Martino,

Welcome to the AutoIt forums.

My GUIListViewEx UDF (look in my sig for the link) does this for you - and quite a bit more!

Martino · October 24, 2017

I saw your UDF before and tried it already but i had the same result.
I try to use this one again and paste my code here.

Melba23 · October 24, 2017

Martino,

Works fine for me:

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

#include "GUIListViewEx.au3"

Global $test = "test"

CreateGui()

Func CreateGui()

GUICreate("Test Gui", 1000, 600)

Global $idListview = GUICtrlCreateListView("#  | COL 1  | COL 2 | COL 3  ", 10, 10, 800, 450) ;,$LVS_SORTDESCENDING)

_GUICtrlListView_SetColumnWidth($idListview, 2, 250)

For $n = 1 To   5
  GUICtrlCreateListViewItem($n & "|" & $n & "|" & $test & "|" & $n + 2, $idListview)
Next

Sorry Melba23, but i can't use it. It's too much info for me at once. I believe your file has very much possibilities but at this time so much info is confusing me.
Maybe you can help me step by step.

First step. I have already the Listview and i populate the list with

For $n = 1 To   5
  GUICtrlCreateListViewItem($n & "|" & $n & "|" & $test & "|" & $n + 2, $idListview)
Next

In my big program i have 3 separate arrays with the vallues, so then it's

For $n = 1 To   5
  GUICtrlCreateListViewItem($n & "|" & $First_array[$n] & "|" & $Second_Array[$n] & "|" & $Third_Array[$n], $idListview)
Next

Is this ok or do i first need to store all the information in some kind of 2D-array and then populate the listview with the elements of the 2D-array?

Martino · October 24, 2017

Melba23,

While i was writing my reply you posted the working code.

In the mean time i tested your code and it seems to work.

I'll try it in my big pprogram.

Thank you already for your verry quick response.

I'll inform you later

Martino · October 24, 2017

Yes, Thank you Melba,

list is editable.
Now i need to do some surgery in my program to continue.

kylomas · October 24, 2017

Martino,

F.Y.I. after looking at your code...

Please note, do NOT call a blocking function (InputBox and MsgBox) from within a registered function or a function called by a registered function. Also, you are trying to delete and recreate your gui from a function that will return to a registered function. That may also cause problems.

Martino · October 24, 2017

I'll keep your info in mind. Thanks.
i think i know what you mean.

Now i'm strugling with Melba's _GUIListViewEx_ReturnArray to retrieve the items from the listview back to my arrays.
Or is there a more simple solution to do this?

I now can edit the listview items but when i push a button the items in the list should be checked for format etc. and after that my idea is to display a message if all items are correct and activate another button to export all the list items.

Melba23 · October 24, 2017

Martino,

What do you find difficult about retrieving the array using the _ReturnArray function? You just call the function using the handle/ControlID of the ListView.

As to checking the content for format etc, you can do this 2 ways: check after each individual edit action as the _EventMonitor function returns an array of the changed elements; or read the content into an array as above and check each element at that time. Let me know which of the two you prefer and I will amend my example above to show how it can be done.

M23

Martino · October 25, 2017

I'm sorry Melba,

but it's probably because i don't have much experience with autoit. It's only my second project.
I'm interested in your first option with the _EventMonitor function.

For your other question.
I was not yet successfulyl on retrieving the data from the listview to an array.
Mostly because i don't understand your result. It's working in my program but i don't know why. So first i'm going to read and explore your GUIListViewEx.au3

Concrete i don't understand

$aLV_Content = _GUIListViewEx_ReadToArray($idListview)
$iLV_Index = _GUIListViewEx_Init($idListview, $aLV_Content)
_GUIListViewEx_SetEditStatus($iLV_Index, "2") ; Make the "test" column editable
_GUIListViewEx_MsgRegister()

I'm going to exlore this first. But any help is welcome of course.

I like the response times in this forum.

Martino · October 25, 2017

OK. i spent a little bit more time on reading the comments in Melba's GUIListViewEx.au3 and i must say it's very complete.

So i understand it more now.

$aLV_Content = _GUIListViewEx_ReadToArray($idListview)

Line above creates an array from the listview with the name $idListview.
What i did not knew was the kind of array. But it seems to me that it's a 2D array

so $aLV_Content[2][0] gives me the first element of the third line of the Listview. The third line because ListView data starts in [0] element of array (default).

$iLV_Index = _GUIListViewEx_Init($idListview, $aLV_Content)

The line above is just to enable the UDF functions for the ListView

_GUIListViewEx_SetEditStatus($iLV_Index, "2") ; Make the "test" column editable

Line above is obvious to make the third column editable

_GUIListViewEx_MsgRegister

And the line above is to register the Windows messages.

So now my listView is editable and i know that my data is in a 2D array so i can continue my work.

Thanks again Melba23.

Martino · October 25, 2017

And with

Local $ArraywithEdits = _GUIListViewEx_EventMonitor()

you can retrieve the edit items. It's also a 2D array

$ArraywithEdits[0][0] is displaying the number of edits (Always 1 in my case

$ArraywithEdits[1][0] is displaying the edited item linenumber where result 0 is the first line

$ArraywithEdits[1][1] is displaying the edited item column number where result 0 is the first column

$ArraywithEdits[1][2] is displaying the old value

$ArraywithEdits[1][3] is displaying the newly stored value

Great job Melba

Martino · November 7, 2017

I still have two questions.

- Now i can edit a listitem. But when i click a list item and when i click once more somewhere outside the edit box, My GUI is closing.

Some little more info. In my code i have

Do

      If @extended = 1 Then 
      ***some more code ****
      EndIf

Until GUIGetMsg() = $GUI_EVENT_CLOSE

- Secondly, in my first column there are the names of files (pdf). I would like to open them when i double click on them.

Anyone any starting help for one of these?

Melba23 · November 7, 2017

Martino,

You need to do some errorchecking of the return from _GUIListViewEx_EventMonitor as shown in the various examples that I add to the UDF download. By clicking outside the edit control you are aborting the edit process and so do not get an array returned - this you get a fatal error when you try to access it, as is shown n the SciTE console.

Add some error-checking and it all works:

#include <GUIConstantsEx.au3>

#include <GUIListViewEx.au3>

Global $GuiSamenvatting = GUICreate("Gui", 1500, 600)

Global $btn_Verplaats = GUICtrlCreateButton(" save", 1250, 10, 150)
GUICtrlSetState($btn_Verplaats, $GUI_ENABLE)

$idListview = GUICtrlCreateListView("#  | FILES  | PROJECTCODE | DOCNR | DOCCODE | DOCSOORT | DOELLOCATIE  ", 10, 10, 1200, 450) ;,$LVS_SORTDESCENDING)
For $n = 1 To 10 ;  $aantgevondenpdfen
    GUICtrlCreateListViewItem($n & "|" & $n & "|" & $n & "|" & $n & "|" & $n & "|" & $n & "|" & $n, $idListview)
Next
_GUICtrlListView_SetColumnWidth($idListview, 1, 250)
_GUICtrlListView_SetColumnWidth($idListview, 2, 100)
_GUICtrlListView_SetColumnWidth($idListview, 3, 70)
_GUICtrlListView_SetColumnWidth($idListview, 4, 100)

All clear now?

Martino · November 7, 2017

Thank you Melba.

Code below has done it.

If $ArrayMetItemsListView <> "" Then ; If edit not aborted

Maybe you can also help me on my second question.
How can i retrieve a double click on the first column and open a pdf ?

Martino · November 7, 2017

So if

;$ArraywithEdits[1][1] = 1

i i would like to open the pdf and not to show the editbox in the listviiew

Melba23 · November 7, 2017

Martino,

Use _GUIListViewEx_SetEditStatus with $iMode = 9 and then you can run a user-defined function when the item is double-clicked. Your function should ShellExecute the pdf file selected - you need the function to accept 4 parameters which will allow you to determine which file to open; these parameters are defined in the _GUIListViewEx_SetEditStatus function header.

Give it a try and come back if you have problems.
