Not sure why this ListView_GetItemText not working..

[Damein]

Alright, so I have this as an example:

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

Opt("GUIOnEventMode", 1)

$Gui = GuiCreate("Test", 400,500)
GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")
$TreeView = GUICtrlCreateTreeView(10, 10, 100, 300)
$TreeViewItem = GUICtrlCreateTreeViewItem("Test", $TreeView)
$TreeViewItemSub = GUICtrlCreateTreeViewItem("Sub Test", $TreeViewItem)
$ListView = GUICtrlCreateListView("List", 160, 10, 200, 200)
_GUICtrlListView_AddItem($ListView, "TestItem")
_GUICtrlListView_AddItem($ListView, "TestItem2")
_GUICtrlListView_AddItem($ListView, "TestItem3")
GuiCtrlCreateButton("Read", 20, 400)
GUICtrlSetOnEvent(-1, "_Read")
GuiSetState()

Func _Read()
    $Index = ControlListView($Gui, "Test", $ListView,"GetSelected")
    $txt = _GUICtrlListView_GetItemText($ListView, $Index)
    MsgBox(0, "Test", "Index: " & $Index & @CRLF & "Data: " & $txt)
EndFunc

Func _Exit()
    Exit
EndFunc

While 1
    Sleep(10)
WEnd 

Now the MsgBox for $index shows the correct number but the MsgBox for $txt is blank. But if I manually set $Index = 1 the MsgBox for $txt show's the data for that item...

Can the GetItemText not use a variable for it's count or am I doing something wrong here?

Thanks!

Damein,

You are creating the ListView using the native function and adding the items using the UDF function - a sure recipe for tears. As a result, you are not getting the correct value for ControlId/handle to use with _GUICtrlListView_GetItemText. Best to stick with the native functions like this:

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

Opt("GUIOnEventMode", 1)

$Gui = GUICreate("Test", 400, 500)
GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")
$TreeView = GUICtrlCreateTreeView(10, 10, 100, 300)
$TreeViewItem = GUICtrlCreateTreeViewItem("Test", $TreeView)
$TreeViewItemSub = GUICtrlCreateTreeViewItem("Sub Test", $TreeViewItem)
$ListView = GUICtrlCreateListView("List           ", 160, 10, 200, 200)
GUICtrlCreateListViewItem("TestItem1", $ListView)
GUICtrlCreateListViewItem("TestItem2", $ListView)
GUICtrlCreateListViewItem("TestItem3", $ListView)
GUICtrlCreateButton("Read", 20, 400)
GUICtrlSetOnEvent(-1, "_Read")
GUISetState()

Func _Read()
    $txt = StringTrimRight(GUICtrlRead(GUICtrlRead($ListView)), 1)
    MsgBox(0, "Test", "Data: " & $txt)
EndFunc   ;==>_Read

Func _Exit()
    Exit
EndFunc   ;==>_Exit

While 1
    Sleep(10)
WEnd

All clear?

Dunno, doesn't work here either, but when i change

$Index = ControlListView($Gui, "Test", $ListView,"GetSelected")

For

$Index = _GUICtrlListView_GetNextItem($ListView, -1, 0, 8)

It works, so there must be a problem with

$Index = ControlListView($Gui, "Test", $ListView,"GetSelected"), parameters seem correct..

EDIT: arrived too late

I'll look over your stuff Melba but I thought I'd post what I tried randomly and got to work.. which I don't think should of worked! Lol!

Seem's to be a weird bug, obviously it has problems with a variable being used if no number is presented so I tried this and viola it works perfectly.

$Text = _GUICtrlListView_GetItemText($ListView, 0+$Index)

So in full:

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

Opt("GUIOnEventMode", 1)

$Gui = GuiCreate("Test", 400,500)
GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")
$TreeView = GUICtrlCreateTreeView(10, 10, 100, 300)
$TreeViewItem = GUICtrlCreateTreeViewItem("Test", $TreeView)
$TreeViewItemSub = GUICtrlCreateTreeViewItem("Sub Test", $TreeViewItem)
$ListView = GUICtrlCreateListView("List", 160, 10, 200, 200)
_GUICtrlListView_AddItem($ListView, "TestItem")
_GUICtrlListView_AddItem($ListView, "TestItem2")
_GUICtrlListView_AddItem($ListView, "TestItem3")
GuiCtrlCreateButton("Read", 20, 400)
GUICtrlSetOnEvent(-1, "_Read")
GuiSetState()

Func _Read()
    $Index = ControlListView($Gui, "Test", $ListView,"GetSelected")
    $Text = _GUICtrlListView_GetItemText($ListView, 0+$Index)
    MsgBox(0, "Test", "Index: " & $Index & @CRLF & "Data: " & $Text)
EndFunc

Func _Exit()
    Exit
EndFunc

While 1
    Sleep(10)
WEnd

Beginning with ControlListview why didn't you continue ?

$txt = ControlListView($Gui, "Test", $ListView,"GetText", $Index)

Edit

BTW the helpfile is clear about ControlListview(.... , "GetSelected") :

"Returns a string containing the item index of selected items"

so this works

$txt = _GUICtrlListView_GetItemText($ListView, Number($Index))
