insert item in ListView at specific position...

[Luigi]

How insert an item between ids 275 And 300?

For example, I need insert id 280.

280 is more of 275, your position is after 275 (position 1) or

275 is less of 300, your position is before 300 (position 2).

How insert correctly a new ID between a number sequence?

How do get a correct position ti insert a new id?

or the best way is insert a new ID anywhere, and sort the list by ID?

sort a small list is very fast, but my list contains more 8k itens... is very low...

#include <GUIConstantsEx.au3>

#include <GuiListView.au3>

Local $hListView

GUICreate('ListView', 400, 300)

$hListView = GUICtrlCreateListView("", 2, 2, 394, 268)

GUISetState()

_GUICtrlListView_AddColumn($hListView, 'id', 100)

_GUICtrlListView_AddItem($hListView, 200); position 0

_GUICtrlListView_AddItem($hListView, 275); position 1

_GUICtrlListView_AddItem($hListView, 300); position 2

Do

Until GUIGetMsg() = $GUI_EVENT_CLOSE

GUIDelete()

Looks like you need _GUICtrlListView_InsertItem()

detefon,

Just sort the ListView after inserting the items:

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>

Local $hListView, $fSort = False

GUICreate('ListView', 400, 300)
$hListView = GUICtrlCreateListView("", 2, 2, 394, 268)
GUISetState()

_GUICtrlListView_AddColumn($hListView, 'id', 100)

GUICtrlCreateListViewItem(200, $hListView)
GUICtrlCreateListViewItem(300, $hListView)
GUICtrlCreateListViewItem(275, $hListView)

_GUICtrlListView_SimpleSort ($hListView, $fSort, 0)

Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

I changed the item insertion code to the native function - it is usually better to keep the ListView creation and item insertion code matched (either both native or both UDF).

hi Melba23, thank you for your reply! 8)

I thinking about sort the list view, and work very well with small list, but my list have more 8k lines.

I try use a simple sort before, but something in wrong.

I will try your code... maybe work now.

detefon,

A ListView with more than 8k lines is, to put it mildly, just ridiculous. Do do you really expect people to scroll through that many items? Can you not break it up into smaller chunks and use a 2-step process?

Edit: Even better - get the items into an array, sort them and then reload.

Edit 2: I see BrewManNH had the same thought.

I've had listviews with over 4K items in it, displaying music files in a media player. Sorting a large listview in AutoIt is going to take a long time.

I've learned to use an array of the items and just sort the array and rebuild the LV with the sorted array, orders of magnitude faster that way.

Another way to fast sort a listview is to use SQLite and a temporary memory database to store the data, and an array when you retrieve it.

detefon,

You already said that (but thanks for saying it again).

But what about the "array" sorting method both BrewManNH and I suggested? I think it is a better solution.

Melba, I have some problems with android keyboard and very slow internet conection, sorry by double posts, its my mistake.

BrewManNH, I will folow your advice and Melba too, and split this list view. 8k lines is funny.
