Listview Disable Column Headers + Mouse cursor

Recommended Posts

Terenz

Hi all. From this script of Melba:

http://www.autoitscript.com/wiki/Snippets_(_GUI_)#Disable_Specific_Column_Headers

You can disable specific column header. There is only a little problem, the mouse cursor is always changing

I think there is a EVENT when the mouse is over a column or when you try to change the column width with the mouse but i dont' have found it

Thanks for the help

Terenz,

I found that method of disabling single headers in another language and converted it to AutoIt code. I seem to remember that in the original article it was mentioned that there was no simple way to prevent the change to the mouse cursor and that it would involve all sorts of complicated stuff without giving any details of what exactly was required. That was why I did not do it myself. Good luck in your search! :D

I have found a possible solution ( in C++ )

http://www.mikaellinusson.com/tech/2013/09/04/how-to-disable-resizing-in-a-listview-win32-c/

I have try but probably i'm missing something, don't know c++

P.S. I have just noticed you miss to "catch" the double click on the header for automatic resizing, also if is disable it moves :D

#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiListView.au3>
#include <HeaderConstants.au3>

; The 0-based column to be disabled
Global $iFix_Col, $hHeader

_Main()

Func _Main()
    Local Const $hGUI = GUICreate("ListView Fix Column Width", 400, 300)

    Local Const $hListView = GUICtrlCreateListView("Column 0|Column 1|Column 2|Column 3", 2, 2, 394, 268)
    $hHeader = _GUICtrlHeader_Create($hGUI)
    GUISetState(@SW_SHOWNORMAL)

    ; Prevent resizing of column 1
    $iFix_Col = 1

    GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY")

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

Func _WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)
    #forceref $hWnd, $iMsg, $wParam
    ; Get details of message
    Local Const $tNMHEADER = DllStructCreate($tagNMHEADER, $lParam)
    Local $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    Local $hWndFrom = DllStructGetData($tNMHDR, "hWndFrom")
    Local Const $iCode = DllStructGetData($tNMHEADER, "Code")
    Switch $hWndFrom
        Case $hHeader
            Switch $iCode
                Case $WM_SETCURSOR
                    Return True
            EndSwitch
    EndSwitch
    Switch $iCode
        Case $HDN_BEGINTRACKW
            ; Now get column being resized
            Local $iCol = DllStructGetData($tNMHEADER, "Item")
            If $iCol = $iFix_Col Then
                ; Prevent resizing
                Return True
            Else
                ; Allow resizing
                Return False
            EndIf
    EndSwitch
EndFunc   ;==>_WM_NOTIFY

Terenz ,

Good find. :thumbsup:

That does not look too difficult to implement - it is a simple subclassing of the ListView header. I will take a look later today and see what I can come up with - but perhaps you can try yourself and see if you can beat me to a solution. ;)

Thanks. Sure i'm trying right now, the main goal is to make everething in the same WM_NOTIFY without register another message, if is possible

Terenz,

It is a bit more complicated than that. :D

I have got the ListView header subclassed and prevented the cursor from changing, but the GUI then becomes unresponsive: :(

#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiListView.au3>
#include <HeaderConstants.au3>
#include <WinAPI.au3>

; The 0-based column to be disabled
Global $iFix_Col
Global $hOld_WndProc
; Get new WndProc hamdle and pointer
Global $hNew_WndProc = DllCallbackRegister("_New_LVHdr_Proc", "lresult", "hwnd;uint;wparam;lparam")
Global $pNew_WndProc = DllCallbackGetPtr($hNew_WndProc)
; To save old WndProc handle
Global $hOld_WndProc

_Main()

Func _Main()
    Local Const $hGUI = GUICreate("ListView Fix Column Width", 400, 300)
    
    Local Const $cListView = GUICtrlCreateListView("Column 0|Column 1|Column 2|Column 3", 10, 10, 380, 220)
    GUICtrlCreateListViewItem("0|1|2|3", $cListView)

    Global $hLVHdr = _GUICtrlListView_GetHeader($cListView)
    
    $cButton = GUICtrlCreateButton("Test", 10, 250, 80, 30)

    GUISetState()

    ; Prevent resizing of column 1
    $iFix_Col = 1

    ; Prevent drag resize
    GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY")

    ; SubClass LV Header
    $hOld_WndProc = _WinAPI_SetWindowLong($hLVHdr, $GWL_WNDPROC, $pNew_WndProc)
    ConsoleWrite("Old proc: 0x" & Hex($hOld_WndProc, 8) & @CRLF)

    ; Loop until user exits
    While 1
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE
                Exit
            Case $cButton
                ConsoleWrite("Pressed" & @CRLF)
        EndSwitch
    WEnd

    GUIDelete($hGUI)
EndFunc   ;==>_Main

Func _WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)

    ; Get details of message
    Local $tNMHEADER = DllStructCreate($tagNMHEADER, $lParam)
    ; Look for header resize code
    $iCode = DllStructGetData($tNMHEADER, "Code")
    Switch $iCode
        Case $HDN_BEGINTRACKW
            ; Now get column being resized
            Local $iCol = DllStructGetData($tNMHEADER, "Item")
            If $iCol = $iFix_Col Then
                ; Prevent resizing
                Return True
            Else
                ; Allow resizing
                Return False
            EndIf
    EndSwitch

EndFunc

Func _New_LVHdr_Proc($hWnd, $iMsg, $wParam, $lParam)

    Switch $iMsg
        Case $WM_SETCURSOR
            Return TRUE
    EndSwitch

    ; Now call previous WndProc and complete the chain
    Return _WinAPI_CallWindowProc($hOld_WndProc, $hWnd, $iMsg, $wParam, $lParam)

EndFunc   ;==>_No_LVHdr_Resize
It also blocks the cursor change for all columns. Anyone got any bright ideas? :huh:

Melba,

Do you know an autoit issue with the subclassing where the internal code seems to be stuck in an infinite loop so that you can't do anything?

I'm saying this because it's the same thing in your script.

Edit: Resize a column and you'll see what's going on.

FireFox,

No, it is a new problem to me - I can see what is happening, but I have no idea why. Whenever I have subclassed controls before it has worked without problem - see my NoFocusLines & GUIFrame UDFs for examples. So I am at a loss as to why it is happening this time. :wacko:

Have you got any issues with the quoted examples ? I can't reproduce the bug.

If you want we can talk by PM. I have this issue with a script so I dropped it...

I'm willing to open a ticket if nothing is found to prevent it.

FireFox,

I suggest opening a thread in Dev Chat to attract the attention of the cognoscenti. Post your failing example and I will add mine. Both of the UDFs I mentioned above still work so there is no obvious problem with subclassing itself in AutoIt - it must be something in these particular cases. :wacko:

Alright :)

Now back to the thread, the best corresponding code I've found is -12 for the NOTIFY message (I didn't find the constant associated with it), but the structure does not return the hovered item...

I would get the mouse position to find the column hovered and then change the cursor or not.

Br, FireFox.

I can't make so much for help you guys. This script prevent the resizing AND the double click on the column, nothing about the cursor

#include <GUIConstants.au3>
#include <WindowsConstants.au3>
#include <StructureConstants.au3>
#include <HeaderConstants.au3>

Global $iFix_Col = 1
Global Const $HDN_ITEMCHANGINGA = $HDN_FIRST - 0

$hGUI = GUICreate("Test", 420, 240)
$iListView = GUICtrlCreateListView("Column1|Column2", 20, 20, 380, 200)
GUICtrlCreateListViewItem("Item 1|SubItem 1", $iListView)
GUICtrlCreateListViewItem("Item 2|SubItem 2", $iListView)

GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY")

GUISetState(@SW_SHOW)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Func _WM_NOTIFY($hWndGUI, $MsgID, $wParam, $lParam)
    Local Const $tNMHEADER = DllStructCreate($tagNMHEADER, $lParam)
    Local Const $TagNMHDR = DllStructCreate("int;int;int", $lParam)
    Local Const $iEvent = DllStructGetData($TagNMHDR, 3)
    Switch $iEvent
        Case $HDN_ITEMCHANGINGA, $HDN_ITEMCHANGINGW
            Local $iCol = DllStructGetData($tNMHEADER, "Item")
            If $iCol = $iFix_Col Then Return True
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_NOTIFY

Is pratically the same, i didn't notice.

An easy way, is possible to set an event on hover on the column header ( like find the area occupied by the header with GetWindowRect and if mouse is in that area = hover ) and if disabled ( just check the flag ) then use guisetcursor with the arrow?

Or guisetcursor will be overrided by the listview?
