clear listview columns and rows

[EscapeTheFate]

Okay so basically I need something that will clear the listview and I don't even know where to start.

expandcollapse popup

$ColdMagic = GUICtrlCreateCombo("", 20, 30, 255, 25, $CBS_DROPDOWNLIST)
GUICtrlSetData(-1, "Cold|Fire");, IniRead($path, "gui_elements", "stat", "0"))
GUICtrlSetFont(-1, 8, 800, 0, "MS Sans Serif")
guictrlsetonevent($coldmagic,"function1")
$listview = GUICtrlCreateListView ("Item Name      |Class|Price|Rqd Stats",10,60,305,300)
func function1()
    If GUICtrlRead($coldmagic) = "Cold" Then

Clearlistview() <<<< how would I do that

$ColdItem1=GUICtrlCreateListViewItem("Snowflake|1|12",$listview)
$ColdItem2=GUICtrlCreateListViewItem("Icecube|2|58",$listview)
$ColdItem3=GUICtrlCreateListViewItem("Snowball|3|180",$listview)
$ColdItem4=GUICtrlCreateListViewItem("Iceball|4|439",$listview)
$ColdItem5=GUICtrlCreateListViewItem("Vague Frost|5|908",$listview)

I found GUICtrlDelete but that only deletes 1 at a time, and only deletes the specified variable.. is there a way to use it to empty the view list?

I strongly suggest for you to get and use Autoit Beta for Listview commands, there are manu such as these

_GUICtrlListView_DeleteAllItems, _GUICtrlListView_DeleteItemsSelected

etc, etc

Okay I keep getting an error I tried running the example for _GUICtrlListView_DeleteAllItems and I got an error

"Use GUICtrlDelete to delete items, Or if items were created with UDF functions MAKE sure to pass in handle to control NOT the controlid"

[Valuater]

This is from Beta help 3.2.9.14

... and it works great

expandcollapse popup

#include <GuiConstantsEx.au3>
#include <GuiListView.au3>

Opt('MustDeclareVars', 1)

$Debug_LV = False ; Check ClassName being passed to ListView functions, set to True and use a handle to another control to see it work

Example_Internal()
Example_External()

Func Example_Internal()
    Local $hListView
    
    GUICreate("(Internal) ListView Delete All Items", 400, 300)

    $hListView = GUICtrlCreateListView("col1|col2|col3", 2, 2, 394, 268)
    GUICtrlCreateListViewItem("line1|data1|more1", $hListView)
    GUICtrlCreateListViewItem("line2|data2|more2", $hListView)
    GUICtrlCreateListViewItem("line3|data3|more3", $hListView)
    GUICtrlCreateListViewItem("line4|data4|more4", $hListView)
    GUICtrlCreateListViewItem("line5|data5|more5", $hListView)
    GUISetState()
    
    MsgBox(4160, "Information", "Delete All Items")
    _GUICtrlListView_DeleteAllItems($hListView)
    
    ; Loop until user exits
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
    GUIDelete()
EndFunc   ;==>Example_Internal

Func Example_External()
    Local $GUI, $hListView, $aItems[10][3]
    
    $GUI = GUICreate("(External) ListView Delete All Items", 400, 300)

    $hListView = _GUICtrlListView_Create ($GUI, "col1|col2|col3", 2, 2, 394, 268)
    GUISetState()

    ; 3 column load
    For $iI = 0 To UBound($aItems) - 1
        $aItems[$iI][0] = "Item " & $iI
        $aItems[$iI][1] = "Item " & $iI & "-1"
        $aItems[$iI][2] = "Item " & $iI & "-2"
    Next

    _GUICtrlListView_AddArray ($hListView, $aItems)
    
    MsgBox(4160, "Information", "Delete All Items")
    _GUICtrlListView_DeleteAllItems($hListView)
    
    ; Loop until user exits
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
    GUIDelete()
EndFunc   ;==>Example_External

The UDF delete functions have been changed, and will stay that way.

If you create the items using the built-in create you need to use the the GuiCtrlDelete, otherwise use the UDF functions to create the items and then you can use the UDF delete functions.
