hi,

with the code below you can change the color of the selected item in a listview.

In the example below in red.

Is the same possible with a treeview?

 

 

#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <File.au3>
#include <String.au3>
#include <Array.au3>
#include <GuiListView.au3>

Global $iCurentSelectet = 0, $iCurentSelectetPrev = 0

$hGui = GUICreate("1", 370, 464)

Global $h_ListView = GUICtrlCreateListView("", 4, 32, 362, 414)

_GUICtrlListView_AddColumn($h_ListView, "Items", 362)

GUICtrlCreateListViewItem("TEST", $h_ListView)
GUICtrlCreateListViewItem("TEST2", $h_ListView)


GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY")
GUISetState(@SW_SHOW, $hGui)

While 1
    Sleep(10)
    $msg = GUIGetMsg()
    If $msg = $GUI_EVENT_CLOSE Then Exit
WEnd

Func _WM_NOTIFY($hwnd, $iMsg, $iwParam, $ilParam)

    Local Static $iHot = -1, $iHotPrev = -1
    Local $hWndFrom, $iCode, $tNMHDR, $tInfo

    $hWndListView = $h_ListView
    If Not IsHWnd($hWndListView) Then $hWndListView = GUICtrlGetHandle($h_ListView)

    $tNMHDR = DllStructCreate($tagNMHDR, $ilParam)
