List view item selection event handling

2 posts in this topic

Hi,

I am creating a UI in which I have to populate different data in few comboboxes depending on the item selected in ListView. Basically I want event handling when any of the item is selected.

Can anyone help me in doing this? a sample script would be of great help.

The events are not getting called in OnEvent Mode instead handled in continuous while () loop. 

Thanks in advance

nbaser,

Her you go:

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

$Gui = GUICreate("Test", 400, 250)

$hListView = GUICtrlCreateListView("Col 0    |Col 1    ", 2, 2, 220, 196)
GUICtrlCreateListViewItem("Item 00|Item 01", $hListView)
GUICtrlCreateListViewItem("Item 10|Item 11", $hListView)
GUICtrlCreateListViewItem("Item 20|Item 21", $hListView)
GUICtrlCreateListViewItem("Item 30|Item 31", $hListView)

GUISetState()

GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            ExitLoop
    EndSwitch

WEnd

; This works with either type of ListView
Func WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)

    #forceref $hWnd, $iMsg, $wParam

    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR

    $tNMHDR = DllStructCreate("hwnd;uint_ptr;int_ptr;int;int", $lParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, 1))
    $iCode = DllStructGetData($tNMHDR, 3)

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

    Switch $hWndFrom
        Case $hWndListView
            Switch $iCode
                Case $NM_DBLCLK
                    ConsoleWrite("Row: " & DllStructGetData($tNMHDR, 4) & " - Col: " & DllStructGetData($tNMHDR, 5) & @CRLF)
            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc
All clear? :)
