Auto scroll to last item in Listview

[lyledg]

Hey guys

I have been searching, but not sure how to do the following:

I know about this from the helpfile, but it does not seem to work for me

#Include <GuiListView.au3>
_GUICtrlListView_Scroll($hWnd, $iDX, $iDY)

I need the last item in the Listview selected

Any ideas?

Cheers

Hi,

#include <GuiConstants.au3>
#include <GuiListView.au3>

Opt ('MustDeclareVars', 1)
Dim $listview, $Btn, $msg, $Status
GUICreate("ListView Get Item Count", 392, 322)

$listview = GUICtrlCreateListView("col1|col2|col3", 40, 30, 310, 149, BitOR($LVS_SINGLESEL, $LVS_SHOWSELALWAYS, $LVS_NOSORTHEADER))
_GUICtrlListViewSetColumnWidth($listview, 0, 80) 
For $i = 1 To 1000
    GUICtrlCreateListViewItem("Line " & $i & "|Data " & $i & "|More " & $i, $listview)
Next    
$Btn = GUICtrlCreateButton("Scroll to last line", 126, 260, 140, 30)
$Status = GUICtrlCreateLabel("Item Count: " & _GUICtrlListViewGetItemCount ($listview), 0, 302, 392, 20, BitOR($SS_SUNKEN, $SS_CENTER))
GUISetState()

While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            Exit
        Case $msg = $Btn
            _GUICtrlListViewSetItemSelState($listview, _GUICtrlListViewGetItemCount ($listview) -1, 1, 1)
            _GUICtrlListViewScroll($listview, 0, (_GUICtrlListViewGetItemCount ($listview) -1) * 14)
            GUICtrlSetState($listview, $GUI_FOCUS)
    EndSelect
WEnd

Cheers

Hey guys

Just one more question on this example, how would I be able to scroll up a line at a time and still keep the focus of the line selected?

That's great mate , yes thanks, but one thing that I am still not able to work out is once the highlighted text moves out of the Listview border, how to autoscroll the listview to still see the highlighted text

Hopefully the attached images will help the explanation

Just before scrolling remember selected item and restore selection after scrolling.

_GUICtrlListView_EnsureVisible

[lyledg]

Thanks for the idea Gary, but I am still unable to get this working...

The selected item does not stay visible once the scroll function has moved it outside the border of the Listview

Any ideas or an example what would work, please mate?

If I'm understanding this correctly you want it to auto scroll but keep the one highlight item in view, not possible unless you keep moving the item to the end, for example, get the data, delete the record and add to the end of the listview and select it again.

Yep, Gary you've hit the nail on the head..

I will give it a try..
