Listview Select Item Trouble (making A Browser)

3 posts in this topic

Hi all,

I am having trouble with a browserish app I am creating.

Basically, it is a list of dirs/files. When I enter a directory and go back up, I want that directory selected.

I managed to do that with ControlListView. My problem is that when I press an up/down cursor, I only find that the caret was actually on the first item on the list, despite the directory being so nicely highlighted..

Please observe:

#include <GUIConstants.au3>
#include <Misc.au3>
#include <GuiListView.au3>
$dll = DllOpen("user32.dll")

GUICreate("test", 500, 500)

$listviewtest = GUICtrlCreateListView ("Bah1|Bah2|Bah3|Bah4", 10, 10,430,445, $LVS_LIST + $LVS_NOSORTHEADER + $LVS_SHOWSELALWAYS + $WS_BORDER + $WS_VSCROLL + $LBS_NOTIFY, $LVS_EX_FULLROWSELECT + $LVS_EX_HEADERDRAGDROP + $LVS_EX_GRIDLINES);+ $LVS_EX_CHECKBOXES)
_FirstLevel()

GUISetState(@SW_SHOW)

While 1
 sleep(50)

;If enter pressed..
 If _IsPressed("0D", $dll) Then
    If WinActive ( "test" ) = 1 Then
        $item = GUICtrlRead(GUICtrlRead($listviewtest))
        $item = StringSplit($item, "|", 0)
    ;detecting if selected item is a directory, file or an 'up-level-you-go-tridot-thingie'
     Select
        case $item[4] = "directory"
        $dir = _GUICtrlListViewGetCurSel($listviewtest)
        _SecondLevel()
        
        case else
         If $item[4] = "..." Then
            $item = "..."
           Else
              $item = "file"
         EndIf  
      EndSelect             
        
;now, depending on the itemtype selected, enter deeper into the dungon..
      Select
            case $item = "..."
            _FirstLevel()
            ControlListView ( "test", "", $listviewtest, "Select", $dir)
            case else
    EndSelect
    EndIf
 EndIf

    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            Exit
    EndSelect
WEnd

Func _FirstLevel()
    _GUICtrlListViewDeleteAllItems($listviewtest)
    GUICtrlCreateListViewItem ("a1|a2|a3|file", $listviewtest )
    GUICtrlCreateListViewItem ("b1|b2|b3|file", $listviewtest )
    GUICtrlCreateListViewItem ("c1|c2|c3|file", $listviewtest )
    GUICtrlCreateListViewItem ("x1|x2|x3|directory", $listviewtest )
    GUICtrlCreateListViewItem ("d1|d2|d3|file", $listviewtest )
EndFunc

Func _SecondLevel()
    _GUICtrlListViewDeleteAllItems($listviewtest)
    GUICtrlCreateListViewItem ("up|up|up|...", $listviewtest )
    GUICtrlCreateListViewItem ("A1|A2|A3|file", $listviewtest )
    GUICtrlCreateListViewItem ("B1|B2|B3|file", $listviewtest )
    GUICtrlCreateListViewItem ("C1|C2|C3|file", $listviewtest )
    GUICtrlCreateListViewItem ("D1|D2|D3|file", $listviewtest )
    GUICtrlCreateListViewItem ("E1|E2|E3|file", $listviewtest )
EndFunc

Don't argue with an idiot; people watching may not be able to tell the difference.

_GUICtrlListViewSetItemSelState ($listviewtest, $dir)
                        _GUICtrlListViewSetHotItem($listviewtest, $dir)
Thank you for the reply, I am afraid it isn't quite it, though.

After I go into the directory, and back again I have that directory nicely highlighted. The problem is, when I want to navigate further down and press DOWN, I still get 'a1|a2|a3|file' selected instead of 'd1|d2|d3|d4|file'.

Now, I am not exactly sure what this SetHotItem business is all about.. The documentation's example I run didn't change the selection of the SetHotItem'ed item either.. I could GetHotItem the index, but there was no visible change to the item itself..
