Change icon of checked/unchecked checkbox, and sort them correctly.

3 posts in this topic

Hi all,

In next example, i had to use some code that i has found somewhere here on the forum (please except my apologies the author of this script, i really can not find it).

This example is show how you can change the icons during the checking certain checkbox. I mean, if you check one checkbox, and even if you not select the item itself, the icon of that item is changed, if you uncheck it, then the icon is changing back...

So my problem is, when i starting to sort the items (if some of them have different icons and check states), then i see one big confusion of the items, and they icons when i trying to check/uncheck them again.

If someone could tell me, how to fix this problem, or even it's be better, if there is a way to get the text of the checked/uncheck item (and even if this item is not selected), it will be great - i am will be very grateful.

Here the example:

#include <GUIConstants.au3>
#include <GUIListView.au3>
Opt("GuiOnEventMode", 1)
Global Const $LVM_GETITEM = $LVM_FIRST + 5

Dim $nCurCol = -1
Dim $nSortDir = 1
Dim $bSet = 0
Dim $nCol = -1

$gui = GUICreate("TEST APP!")
$listview = GUICtrlCreateListView("Column 1", 0, 50, 500, 400, $WS_VSCROLL, $LVS_EX_CHECKBOXES + $LVS_EX_GRIDLINES)
GUICtrlRegisterListViewSort(-1, "LVSort") ; Register the function "SortLV" for the sorting callback
GUICtrlSetOnEvent(-1, "Sort")

GUISetOnEvent($GUI_EVENT_PRIMARYDOWN, "CheckBoxesEvent")
GUISetOnEvent($GUI_EVENT_CLOSE, "Quit")

Dim $Item[11]
For $i = 1 To 10
    $Item[$i] = GUICtrlCreateListViewItem($i, $listview)
    GUICtrlSetImage(-1, "shell32.dll", 10)
Next

GUISetState(@SW_SHOW, $gui)

While 1
    Sleep(100)
WEnd

Func Sort()
    $bSet = 0
    $nCurCol = $nCol
    GUICtrlSendMsg($listview, $LVM_SETSELECTEDCOLUMN, GUICtrlGetState($listview), 0)
    DllCall("user32.dll", "int", "InvalidateRect", "hwnd", GUICtrlGetHandle($listview), "int", 0, "int", 1)
EndFunc

Func CheckBoxesEvent()
    $ItemsCount = _GUICtrlListViewGetItemCount($listview)
    For $i = 1 To $ItemsCount
        If _GUICtrlListViewGetCheckedState($listview, $i-1) = 1 Then
            GUICtrlSetImage($Item[$i], "shell32.dll", 8)
        Else
            GUICtrlSetImage($Item[$i], "shell32.dll", 10)
        EndIf
    Next
EndFunc

Func Quit()
    Exit
EndFunc

; Our sorting callback funtion
Func LVSort($hWnd, $nItem1, $nItem2, $nColumn)
    Local $nSort
   
    ; Switch the sorting direction
    If $nColumn = $nCurCol Then
        If Not $bSet Then
            $nSortDir = $nSortDir * - 1
            $bSet = 1
        EndIf
    Else
        $nSortDir = 1
    EndIf
    $nCol = $nColumn
    $val1 = GetSubItemText($listview, $nItem1, $nColumn)
    $val2 = GetSubItemText($listview, $nItem2, $nColumn)
   
    $nResult = 0        ; No change of item1 and item2 positions
   
    If $val1 < $val2 Then
        $nResult = -1   ; Put item2 before item1
    ElseIf $val1 > $val2 Then
        $nResult = 1    ; Put item2 behind item1
    EndIf
   
    $nResult = $nResult * $nSortDir
   
    Return $nResult
EndFunc   ;==>LVSort

; Retrieve the text of a listview item in a specified column
Func GetSubItemText($nCtrlID, $nItemID, $nColumn)
    Local $stLvfi = DllStructCreate("uint;ptr;int;int[2];int")
    DllStructSetData($stLvfi, 1, $LVFI_PARAM)
    DllStructSetData($stLvfi, 3, $nItemID)
   
    Local $stBuffer = DllStructCreate("char[260]")
   
    $nIndex = GUICtrlSendMsg($nCtrlID, $LVM_FINDITEM, -1, DllStructGetPtr($stLvfi));
   
    Local $stLvi = DllStructCreate("uint;int;int;uint;uint;ptr;int;int;int;int")
   
    DllStructSetData($stLvi, 1, $LVIF_TEXT)
    DllStructSetData($stLvi, 2, $nIndex)
    DllStructSetData($stLvi, 3, $nColumn)
    DllStructSetData($stLvi, 6, DllStructGetPtr($stBuffer))
    DllStructSetData($stLvi, 7, 260)
   
    GUICtrlSendMsg($nCtrlID, $LVM_GETITEM, 0, DllStructGetPtr($stLvi));
   
    $sItemText = DllStructGetData($stBuffer, 1)
   
    $stLvi = 0
    $stLvfi = 0

hi,

Here's a nearly working workaround (* needs many of the files in mu GUIListView zip from signature to work)

At present, click on column 1st time only 3 times! oh well, gives the idea;

$searchdir = "c:\"
$gui = GUICreate("TEST APP!")
;===================================================================

$listview = _GUICtrlCreateListViewIndexed ("Column 1", 0, 50, 500, 400, $WS_VSCROLL, $LVS_EX_CHECKBOXES + $LVS_EX_GRIDLINES)

If $i_GUISetCheckBoxes=2 Then   _GUICtrlListViewSetCheckState($listview, -1, 1)

Wow! thanks, it works.

Maybe you also know, how to get "check state" event? i mean, if i check/uncheck the checkbox of listvivew item, and the item is not selected, then i would like to see a MsgBox with a text of that item... but without actualy over the all items to see if they checked or not (as i did in my example), just for one item. It is possible?
