WM_COMMAND and ListView/TreeView Items

Recommended Posts

Trying to use WM_COMMAND and WM_CONTEXTMENU in my GUI, and I'm having issue with the fact that WM_COMMAND doesn't fire when the mouse is over a listview or treeview.

You can try to simulate my issue with the example code below. The WM_COMMAND will fire whenever the menu is created over the GUI background, but not when the menu is over the listview.

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

Global Enum $idOpen = 1000, $idSave, $idInfo

_Main()

Func _Main()
    ; Create GUI
    GUICreate("Menu", 400, 300)
    $hlistview = GUICtrlCreateListView("", 10, 10, 150, 280)
    GUISetState()

    ; Register message handlers
    GUIRegisterMsg($WM_COMMAND, "WM_COMMAND")
    GUIRegisterMsg($WM_CONTEXTMENU, "WM_CONTEXTMENU")

    ; Loop until user exits
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
EndFunc   ;==>_Main

; Handle WM_COMMAND messages
Func WM_COMMAND($hWnd, $iMsg, $iwParam, $ilParam)
    #forceref $hWnd, $iMsg, $ilParam
    Switch $iwParam
        Case $idOpen
            _WinAPI_ShowMsg("Open")
        Case $idSave
            _WinAPI_ShowMsg("Save")
        Case $idInfo
            _WinAPI_ShowMsg("Info")
    EndSwitch
EndFunc   ;==>WM_COMMAND

; Handle WM_CONTEXTMENU messages
Func WM_CONTEXTMENU($hWnd, $iMsg, $iwParam, $ilParam)
    #forceref $hWnd, $iMsg, $ilParam
    Local $hMenu

    $hMenu = _GUICtrlMenu_CreatePopup()
    _GUICtrlMenu_InsertMenuItem($hMenu, 0, "Open", $idOpen)
    _GUICtrlMenu_InsertMenuItem($hMenu, 1, "Save", $idSave)
    _GUICtrlMenu_InsertMenuItem($hMenu, 3, "", 0)
    _GUICtrlMenu_InsertMenuItem($hMenu, 3, "Info", $idInfo)
    _GUICtrlMenu_TrackPopupMenu($hMenu, $iwParam)
    _GUICtrlMenu_DestroyMenu($hMenu)
    Return True
EndFunc   ;==>WM_CONTEXTMENU

Can anyone help me out with this?

Thanks!

Try it using WM_NOTIFY for the listview.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I currently use WM_NOTIFY to set global elements to tell the WM_CONTEXTMENU which menu to build.

I wish I could attach my actual code, but it contains elements that are security sensitive (login information) and simply eliminating that information will yield a brick of code.

Here is my WM_NOTIFY (global variables set are $menu, $menuitem, and $menuitem_key):

Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)
    #forceref $hWnd, $iMsg, $iwParam
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndTreeview, $hWndListView
    $hWndTreeview = $hTreeView
    If Not IsHWnd($hTreeView) Then $hWndTreeview = GUICtrlGetHandle($hTreeView)
    $hWndListView = $hListView
    If Not IsHWnd($hListView) Then $hWndListView = GUICtrlGetHandle($hListView)

    $tNMHDR = DllStructCreate($tagNMHDR, $ilParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")
    Switch $hWndFrom
        Case $hWndListView
            $menu = "listview"
            Switch $iCode
                Case $LVN_COLUMNCLICK
                    Local $tInfo = DllStructCreate($tagNMLISTVIEW, $ilParam)
                    Local $ColumnIndex = DllStructGetData($tInfo, "SubItem")
                    _ListView_Sort($ColumnIndex)
                    Return 0
                Case $NM_CLICK ; The user has clicked the right mouse button within the control
                    Local $tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam)
                    Local $text = _GUICtrlListView_GetItemText($hWndListView, DllStructGetData($tInfo, "Index"))
                    Local $hItem = _GUICtrlListView_GetItem($hWndListView, DllStructGetData($tInfo, "Index"))
                    $menu = "file"
                    $menuitem = $text
                    $menuitem_key = $_MF_File_Tree[_GUICtrlListView_GetItemParam($hWndListView, DllStructGetData($tInfo, "Index"))][0]
                    Return 0
                Case $NM_RCLICK ; The user has clicked the right mouse button within the control
                    Local $tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam)
                    Local $text = _GUICtrlListView_GetItemText($hWndListView, DllStructGetData($tInfo, "Index"))
                    Local $hItem = _GUICtrlListView_GetItem($hWndListView, DllStructGetData($tInfo, "Index"))
                    $menu = "file"
                    $menuitem = $text
                    $menuitem_key = $_MF_File_Tree[_GUICtrlListView_GetItemParam($hWndListView, DllStructGetData($tInfo, "Index"))][0]
                    Return 0
                EndSwitch

        Case $hWndTreeview
            $menu = "folder"
            Switch $iCode
                Case $NM_CLICK ; The user has clicked the left mouse button within the control
                    _DebugPrint("$NM_CLICK" & @LF & "--> hWndFrom:" & @TAB & $hWndFrom & @LF & _
                            "-->IDFrom:" & @TAB & $iIDFrom & @LF & _
                            "-->Code:" & @TAB & $iCode)
;~                Return 1 ; nonzero to not allow the default processing
                    Return 0 ; zero to allow the default processing
                Case $NM_DBLCLK ; The user has double-clicked the left mouse button within the control
                    _DebugPrint("$NM_DBLCLK" & @LF & "--> hWndFrom:" & @TAB & $hWndFrom & @LF & _
                            "-->IDFrom:" & @TAB & $iIDFrom & @LF & _
                            "-->Code:" & @TAB & $iCode)
;~                Return 1 ; nonzero to not allow the default processing
                    Return 0 ; zero to allow the default processing
                Case $NM_RCLICK ; The user has clicked the right mouse button within the control
                    _DebugPrint("$NM_RCLICK" & @LF & "--> hWndFrom:" & @TAB & $hWndFrom & @LF & _
                            "-->IDFrom:" & @TAB & $iIDFrom & @LF & _
                            "-->Code:" & @TAB & $iCode)
                    Local $tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam)

;~                Return 1 ; nonzero to not allow the default processing
                    Return 0 ; zero to allow the default processing
                Case $NM_RDBLCLK ; The user has clicked the right mouse button within the control
                    _DebugPrint("$NM_RDBLCLK" & @LF & "--> hWndFrom:" & @TAB & $hWndFrom & @LF & _
                            "-->IDFrom:" & @TAB & $iIDFrom & @LF & _
                            "-->Code:" & @TAB & $iCode)
;~                Return 1 ; nonzero to not allow the default processing
                    Return 0 ; zero to allow the default processing
                Case $TVN_SELCHANGEDW
;~                     Local $tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam)
                    $treeview_change = True
                    Return 0
            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_NOTIFY

So I suppose my question then is, how do I get WM_NOTIFY to realize that I clicked on the corresponding menu item?

Here is my WM_CONTEXTMENU in case it is needed for reference:

Func WM_CONTEXTMENU($hWnd, $iMsg, $iwParam, $ilParam)
    #forceref $hWnd, $iMsg, $ilParam
    Local $hMenu

    If $menu == "" or $menu == "none" Then Return True

    $hMenu = _GUICtrlMenu_CreatePopup(32)
    If $hMenu = 0 Then MsgBox(0, "Menu", "Error")

    Select
        Case $menu == "file"
            If $menuitem == "" Then
                _GUICtrlMenu_DestroyMenu($hMenu)
                Return True
            EndIf
            _GUICtrlMenu_InsertMenuItem($hMenu, 0, 'Preview "' & $menuitem & '"', $idPreview)
            _GUICtrlMenu_InsertMenuItem($hMenu, 1, 'Download "' & $menuitem & '"', $idDownload)
            _GUICtrlMenu_InsertMenuItem($hMenu, 2, "Edit Description", $idEditDescription)
            _GUICtrlMenu_InsertMenuItem($hMenu, 3, "Edit Tags", $idEditTags)
            _GUICtrlMenu_InsertMenuItem($hMenu, 4, "", 0)
            _GUICtrlMenu_InsertMenuItem($hMenu, 5, "Rename", $idRename)
            _GUICtrlMenu_InsertMenuItem($hMenu, 6, "Delete key " & $menuitem_key, $idDelete)
        Case $menu == "folder"
            _GUICtrlMenu_InsertMenuItem($hMenu, 0, "Rename", $idRename)
            _GUICtrlMenu_InsertMenuItem($hMenu, 1, "Delete", $idDelete)
            _GUICtrlMenu_InsertMenuItem($hMenu, 3, "", 0)
            _GUICtrlMenu_InsertMenuItem($hMenu, 3, "Info", $idInfo)
        Case $menu == "listview"
            _GUICtrlMenu_InsertMenuItem($hMenu, 0, "Details", $idViewDetails)
            _GUICtrlMenu_InsertMenuItem($hMenu, 1, "Large Icon", $idViewLgIcon)
            _GUICtrlMenu_InsertMenuItem($hMenu, 2, "List", $idViewList)
            _GUICtrlMenu_InsertMenuItem($hMenu, 3, "Small Icon", $idViewSmIcon)
            _GUICtrlMenu_InsertMenuItem($hMenu, 4, "Tile", $idViewTile)
        Case Else

    EndSelect
    _GUICtrlMenu_TrackPopupMenu($hMenu, $iwParam)
    _GUICtrlMenu_DestroyMenu($hMenu)
    Return True
EndFunc   ;==>WM_CONTEXTMENU

      This project has been discontinued!
       
      Here a small tool I wrote to update my Sysinternal tools collection without the need to download always the whole package or visiting the site to check for updates. I know that there are several tools available (also some tools written in AutoIt) but here another one for the collection. It was good exercise for me to code it.
       
       
        
       
       
      Some files from the live web site cannot be downloaded although they are visible!
       
      Here the download link of the source code only: AutoIt Sysinternal Tools Synchronizer v0.99.6 build 2020-09-23 beta.7z  (1557 downloads previously)
      -=> Requires AutoIt version 3.3.13.20 or higher / tested on Win8.1 real machine and some VMs: Win7 / Vista / Win10
       
      Compiled exe only: @MediaFire
       
      Just select the Sysinternal Tools folder or create one and press the synchronize button to download the selected items. Click on AutoIt label (near to left upper corner) to open menu.
       
      Special thanks to LarsJ, Melba23 and mesale0077 for their help. 
       
      I've still some ideas to implement which are more gimmick related, so it is not finished yet...
      If you want to add your language please check out #Region Language. Thanks. 
       
      Please report any bug or if you have any suggestions.
       
      The language of the tool tip from each of the executable in the left list view were automatically created using Google translator and weren't checked for correctness.

      Hi everyone,
      I have created a ListView that is in a tab, and I want to display an image in that tab, with the ListView on top.
      However, the image still appears on top of my ListView.
      If I remove the tabs everything works. 
      I looked at the autoit documentation and the <GuiListView.au3> documentation , I can't figure out how to display a background image, and put on top a ListView, inside a tab. 😥
      Here is the code:
      Opt("GUIOnEventMode", 1) $Form1 = GUICreate($Titre, 700, 627, $Form1Width, $Form1Height); main window $tabulation = GUICtrlCreateTab(148,0,700,580); creating tabs $tab1=GUICtrlCreateTabItem("Tab 1"); first tab GUICtrlSetState(-1, $GUI_SHOW); this tab is selected by default $Pic1 = GUICtrlCreatePic("image.jpg", 0, 30, 700, 627) GUICtrlSetState(-1, $GUI_DISABLE). $idListview = GUICtrlCreateListView("list 1|list 2|list 3", 200, 50, 390, 200) GUISetState(@SW_SHOW) While 1     Sleep(100) WEnd Thank you in advance.

      Hello all.  It's me again.
      I've got a ListView with an associated ImageList to display icons.  What I seem to be hung up on is how to keep the ImageList updated to match the ListView as the latter changes.  I thought it was the case that the indices of the items in the ListView and those in the ImageList just needed to match.  So, for example, if I:
      Delete an item from the ListView [_GUICtrlListView_DeleteItem()], and also delete the image at the matching index in the ImageList [_GUIImageList_Remove()]. Then add a new item to the end of the ListView [_GUICtrlListView_AddItem()], and correspondingly add an image at the end of the ImageList [_GUIImageList_AddIcon()] Shouldn't everything stay in sync?
      Here's the code I thought would work:
      #include <GUIConstantsEx.au3> #include <GuiListView.au3> #include <FontConstants.au3> #include <WindowsConstants.au3> #include <GuiImageList.au3> Test() func Test() $gui = GUICreate("Test", 400, 300) ; Create ListView $lv = _GUICtrlListView_Create($gui, "", 10, 10, 380, 240, $LVS_DEFAULT) _GUICtrlListView_AddColumn($lv, "Col1", 50) _GUICtrlListView_AddColumn($lv, "Col2", 50) for $i = 0 to 2 $s = StringFormat("%d,1", $i+1) _GUICtrlListView_AddItem($lv, $s, $i) $s = StringFormat("%d,2", $i+1) _GUICtrlListView_AddSubItem($lv, $i, $s, 1) next ; Add ImageList $img_list = _GUIImageList_Create(16, 16, 5, 3) for $i = 0 to 2 $ico = StringFormat("%d.ico", $i+1) _GUIImageList_AddIcon($img_list, $ico) next _GUICtrlListView_SetImageList($lv, $img_list, 1) ; $btn = GUICtrlCreateButton("Test", 10, 260, 60, 30) GUISetState(@SW_SHOW) HotKeySet("^q", Quit) ; Loop until the user exits. while True switch GUIGetMsg() case $GUI_EVENT_CLOSE Exit case $btn ; Remove 2nd list item and image _GUICtrlListView_DeleteItem($lv, 1) _GUIImageList_Remove($img_list, 1) ; Add new item to end of ListView $idx = _GUICtrlListView_AddItem($lv, "foo") _GUICtrlListView_AddSubItem($lv, $idx, "bar", 1) ; Add new image to end of ImageList _GUIImageList_AddIcon($img_list, "5.ico") endswitch wend GUIDelete() endfunc func Quit() Exit endfunc What seems to happen is that when the new item is added to the ListView, its icon is 1.ico (the first item in the ImageList), rather than 5.ico (the newly added item that should be at the end of the ImageList).
      Or do I need to re-create the whole ImageList any time the ListView changes?
      A zip file is attached that contains the script and also the .ico files, for easier testing.
      Thanks!
