Terenz Posted February 16, 2014 Share Posted February 16, 2014 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 Nothing is so strong as gentleness.

Moderators Melba23 Posted February 16, 2014 Moderators Share Posted February 16, 2014 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!

Terenz Posted February 16, 2014 Author Share Posted February 16, 2014 (edited) 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 expandcollapse popup#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 Edited February 16, 2014 by Terenz Nothing is so strong as gentleness.

Moderators Melba23 Posted February 16, 2014 Moderators Share Posted February 16, 2014 Terenz ,Good find. 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.

Terenz Posted February 16, 2014 Author Share Posted February 16, 2014 (edited) 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 Edited February 16, 2014 by Terenz Nothing is so strong as gentleness.

Moderators Melba23 Posted February 16, 2014 Moderators Share Posted February 16, 2014 Terenz,It is a bit more complicated than that. I have got the ListView header subclassed and prevented the cursor from changing, but the GUI then becomes unresponsive: expandcollapse popup#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_ResizeIt also blocks the cursor change for all columns.

FireFox Posted February 16, 2014 Share Posted February 16, 2014 (edited) 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.

Moderators Melba23 Posted February 16, 2014 Moderators Share Posted February 16, 2014 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.

FireFox Posted February 16, 2014 Share Posted February 16, 2014 (edited) 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.

Moderators Melba23 Posted February 16, 2014 Moderators Share Posted February 16, 2014 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.

FireFox Posted February 16, 2014 Share Posted February 16, 2014 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.

FireFox Posted February 16, 2014 Share Posted February 16, 2014 And what's different from the post #6 ? Link to comment Share on other sites More sharing options...
Terenz Posted February 16, 2014 Author Share Posted February 16, 2014 (edited) 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? Edited February 16, 2014 by Terenz Nothing is so strong as gentleness.
