_WinAPI_GetDlgCtrlID($hWnd) not work on TreeViewItem

3 posts in this topic

I can get the CtrlID of treeview correctly, but for the treeviewitem it always return 0.

so it's not supported for treeview item?

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#Include <GuiTreeView.au3>
#include <WinAPI.au3>
Opt("GUIOnEventMode", 1)

$gui = GUICreate("", 220, 220)
GUISetOnEvent($GUI_EVENT_CLOSE, "Close")

$tv = GUICtrlCreateTreeView(10, 10, 200, 200)
$root = GUICtrlCreateTreeViewItem("root", $tv)
For $i = 0 To 3
    GUICtrlCreateTreeViewItem("Item" & $i, $root)
Next
GUICtrlSetState($root, $GUI_EXPAND)
GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")
GUISetState()

While 1
    Sleep(1000)
WEnd

Func Close()
    GUIDelete($gui)
    Exit
EndFunc

Func TreeView_ItemChanged($iCtrlID)
    Local $iTree = $tv
    Local $hTree = GUICtrlGetHandle($tv)
    Local $iTree_= _WinAPI_GetDlgCtrlID($hTree)

    Local $iItem = GUICtrlRead($tv)
    Local $hItem = GUICtrlGetHandle($iItem)
    Local $iItem_= _WinAPI_GetDlgCtrlID($hItem)

    ToolTip( _
    "$iTree : "&$iTree &@LF& _
    "$hTree : "&$hTree &@LF& _
    "$iTree_: "&$iTree_&@LF& _
    "$iItem : "&$iItem &@LF& _
    "$hItem : "&$hItem &@LF& _
    "$iItem_: "&$iItem_)
EndFunc

Func WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)
    Local $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    Local $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    Local $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    Local $iCode = DllStructGetData($tNMHDR, "Code")
    Switch $wParam
        Case $tv
            Switch $iCode
                Case $TVN_SELCHANGED, $TVN_SELCHANGEDW
                    TreeView_ItemChanged($wParam)
            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc
