Guictrltreeview help

[AppTux]

I'm making a program for reading all the drives etc. I made a treeview with the fixed drives and the removable drives.

Now, I want to make it that if you click by example the C: drive in the treeview, you see a different content instead of before you clicked it.

But because every pc has another count of drives, I made a array with max 7 fixed disks.

With the functions I used, the GUIGetMsg() won't work on the items in the treeview.

What should be used to check if the item is clicked.

How can I make a loop or whatever to make it possible to check only for the used items? Otherwise you get always a msg.

My code so far:

expandcollapse popup

$TRVI = GUICtrlCreateTreeView(7, 95, 150, 375)
$TRVIMG = _GUIImageList_Create(16, 16, 5, 3)
_GUIImageList_AddIcon($TRVIMG, "Data\wdrive-drive-icon.ico", 0)
_GUIImageList_AddIcon($TRVIMG, "Data\wdrive-removable-icon.ico", 0)
_GUIImageList_AddIcon($TRVIMG, "Data\wdrive-wait-icon.ico", 0)
_GUICtrlTreeView_SetNormalImageList($TRVI, $TRVIMG)
$PLWA = _GUICtrlTreeView_Add($TRVI, 0, "Please wait...",2,2)
_GUICtrlTreeView_BeginUpdate($TRVI)
$TVD = _GUICtrlTreeView_Add($TRVI, 0, "Hard disks", 0, 0)
$TVR = _GUICtrlTreeView_Add($TRVI, 0, "Removable hardware", 1, 1)
$DRIVE = DriveGetDrive("FIXED")
$DREM = DriveGetDrive("REMOVABLE")
For $X = 1 To $DRIVE[0]
    If $X > 7 Then ExitLoop
    $DLETTER = _StringProper($DRIVE[$X])
    $LABEL = DriveGetLabel($DRIVE[$X])
    If $LABEL = "" Then
        $TXT = $DLETTER
    Else
        $TXT = $DLETTER & " " & $LABEL
    EndIf
    $FIXED[$X] = _GUICtrlTreeView_AddChild($TRVI, $TVD, $TXT, 0, 0)
Next
For $X = 1 To $DREM[0]
    If $X > 10 Then ExitLoop
    $DLETTER = _StringProper($DREM[$X])
    $LABEL = DriveGetLabel($DREM[$X])
    If $LABEL = "" Then
        $TXT = $DLETTER
    Else
        $TXT = $DLETTER & " " & $LABEL
    EndIf
    $REMOVABLE[$X] = _GUICtrlTreeView_AddChild($TRVI, $TVR, $TXT, 1, 1)
Next
_GUICtrlTreeView_Delete($TRVI,$PLWA)
_GUICtrlTreeView_EndUpdate($TRVI)
_GUICtrlTreeView_Expand($TRVI, 0, True)
_GUICtrlTreeView_SelectItem($TRVI, $TVD)
;---==>End of Treeview---;

I still have no code for getting message from the items.

I really hope you understand what I mean.

Thanks in advance, Apptux

AppTux,

Just posting an orphan snippet like that is not the way to get help quickly.

No-one is going to waste their time adding all the missing code to get an idea of what you are trying to do. I would be happy to look at your problem if you post a script which at least runs without errors - i.e. has a GUI, all the required include files and declared arrays.

To give you a good start, this is how you can get the selected treeview item by double-clicking or by using a button:

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiTreeView.au3>
#include <Array.au3>

Global $aData[5] = [4, "Item 1", "Item 2", "Item 3", "Item 4"]
Global $aItem_Handles[UBound($aData)]

Global $hMain_GUI = GUICreate("TreeView Demo", 500, 500)

$hTree = GUICtrlCreateTreeView(10, 10, 280, 280)
$hRoot = GUICtrlCreateTreeViewItem("Root", $hTree)
For $i = 1 To $aData[0]
    $aItem_Handles[$i] = GUICtrlGetHandle(GUICtrlCreateTreeViewItem($aData[$i], $hRoot))
Next

$hButton = GUICtrlCreateButton("Check", 10, 400, 80, 30)

GUISetState()

; Initialise "DoubleClick on TreeView function"
GUIRegisterMsg($WM_NOTIFY, "MY_WM_NOTIFY")

Global $fDblClk = False

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $hButton
            MsgBox(0, "Read", "The currently selected item is " & GUICtrlRead($hTree, 1))
    EndSwitch

    ; Check if tree view double clicked
    If $fDblClk = True Then
        $sText = _GUICtrlTreeView_GetText($hTree, _GUICtrlTreeView_GetSelection($hTree))
        MsgBox(0, "Hit", "You double clicked on " & $sText )
        $fDblClk = False
    EndIf
WEnd

Func MY_WM_NOTIFY($hWnd, $Msg, $wParam, $lParam)

    Switch $wParam
        Case $hTree
            Local $tagNMHDR = DllStructCreate("int;int;int", $lParam)
            If @error Then Return
            If DllStructGetData($tagNMHDR, 3) = $NM_DBLCLK Then $fDblClk = True
    EndSwitch

EndFunc  ;==>MY_WM_NOTIFY

See you soon!

Sorry for that, I'm not often on this forum, so I don't think about that things... I'm sorry.

I'll try to make a working script including the 'missing' code

Thanks!!!

This works perfect for me.

Now I get the name of the selected treeviewitem, now can I make a function what's reading the name of the item, and put the right content on the right place. I'll modify my script so you can understand what I wanted.

I'll post soon!
