ListBox Delete Selections - Is ListBox What I should Use?

5 posts in this topic

Hi,

What I want is an uneditable "box" that shows records (rows of text). Through Autoit magic the user adds row(s) and hopefully can delete row(s), but the content of the rows are not editable.

I'd like to have mouse right click copy and delete (but not paste). ..But the listbox seems OK, Through buttons a user can add and delete. And row text can't be edited (at least by default) so it's cool.

But I can't get deletion working right. I want single row and multiple row deletion ( the user is able to select multiple rows) via  *one* " delete" button on the GUI. The code works weirdly for multiple deletes, after a multiple delete is made then a line gets selected for no apparent reason and futher delete attempts give unexpected results. (It's not apparent and unexpected to me only because I don't get what the problem is). Thanks, help appreciated.

#include <GUIConstantsEx.au3>
#include <FF.au3>
#include <Array.au3>
#include <GuiListBox.au3>
#include <StaticConstants.au3>
#include <DateTimeConstants.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <Date.au3>

snip....

$mylist = GUICtrlCreateList("", 200, 32, 320, 260, $LBS_EXTENDEDSEL)

snip...

        Case $msg = $delrowurl ; one delete button for single and multiple selections
            $sItems = _GUICtrlListBox_GetSelItems($mylist)
            ConsoleWrite('  ' & $sItems[0] & @LF)
            If $sItems[0] = 1 Then
                _GUICtrlListBox_DeleteString($mylist, _GUICtrlListBox_GetCurSel($mylist))
            ElseIf $sItems[0] > 1 Then
                For $sli = 1 To UBound($sItems) - 1
                    ConsoleWrite(' ' & $sli & ' ')
                    _GUICtrlListBox_DeleteString($mylist, $sli)
                Next
            EndIf
....

Try it this way.

For $sli = $sItems[0] To 1 Step -1

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

leegold,

BrewNamNH's suggestion is exactly what you need - as this example shows: :)

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiListBox.au3>

$hGUI = GUICreate("Test", 500, 500)

$cList = GUICtrlCreateList("", 10, 10, 480, 300, BitOr($LBS_EXTENDEDSEL, $WS_BORDER, $WS_VSCROLL))
For $i = 0 To 39
    _GUICtrlListBox_AddString($cList, "Line " & $i)
Next
$cDel_Button = GUICtrlCreateButton("Delete", 10, 350, 80, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cDel_Button
            $aSel_Rows = _GUICtrlListBox_GetSelItems($cList)
            For $i = $aSel_Rows[0] To 1 Step -1
                _GUICtrlListBox_DeleteString($cList, $aSel_Rows[$i])
            Next
    EndSwitch

WEnd
You need to delete the items in reverse order or the count become inaccurate for the later items. The same is true when deleting items from an array. ;)

All clear now? :huh:

Yes, I tried it again and followed the suggestion correctly this time.

It's too late at night and I goofed when I tried it the first time...

I'm sorry BrewManNH you are 100% correct. It worked perfectly :)

All clear indeed.
