Prevent listview column resize

13 posts in this topic

Hey guys, I have a column in a listview which is meant to be hidden but not deleted. The reason for this, is because the listview will hold values from an inisectionread and I dont want the names of the keys to appear. Is this possible?

Thanks.

If the values are numerical then may I suggest using _GUICtrlListView_SetItemParam() & _GUICtrlListView_GetItemParam()

Mikeman27294,

To hide a column, just use _GUICtrlListView_SetColumnWidth to set the column width to 0: :graduated:

#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
 
GUICreate("ListView Set Column Width", 400, 300)
$hListView = GUICtrlCreateListView("Column 1|Column 2|Column 3|Column 4", 2, 2, 394, 268)
GUISetState()
 
; Change column 1 width
MsgBox(4160, "Information", "Column 1 Width: " & _GUICtrlListView_GetColumnWidth($hListView, 0))
_GUICtrlListView_SetColumnWidth($hListView, 0, 0)
MsgBox(4160, "Information", "Column 1 Width: " & _GUICtrlListView_GetColumnWidth($hListView, 0))
 
; Loop until user exits
Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

To answer the question in the title, just disable the header: :)

#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
 
$hGUI = GUICreate("ListView Set Column Width", 400, 300)
$hListView = GUICtrlCreateListView("Column 1|Column 2|Column 3|Column 4", 2, 2, 394, 268)
GUISetState()
 
; Prevent resizing of columns
ControlDisable($hGUI, "", HWnd(_GUICtrlListView_GetHeader($hListView)))
 
; Loop until user exits
Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

And before you ask, just use ControlEnable to reenable it. ;)

All clear? ;)

Ah thanks. I have never heard of that ControlDisable one before. I will take a look to make sure it works with my script.

Aah... I found that I had to disable it like this:

ControlDisable($ColumnID, "", "")

Otherwise it would disabl my entire GUI.

But it has worked. Thanks.

Mikeman27294,

Your use of ControlDisable makes no sense at all - the parameters are ("GUI title", "GUI text", "Control ID") and the command works perfectly when you use them, as my example shows. And I do not see how you can disable an entire GUI with this function! :graduated:

What is "$ColumnID"? ;)

Could you post the code you ended up with? :)

Yeah that didnt work for me.

$ColumnID is a variable with the Control ID of the column. I stored it in an array and it works perfectly now, whereas when I tried exactly what you said, it disabled the entire GUI, which has a dropdown box in it to allow the user to change the data.

Anyway, it is fixed now, so thanks.

this will disable all columns, is it possible to disable just one column (for example, the first column)?

netegg,

That was fun! :)

Here is how you can do it:

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

$hGUI = GUICreate("ListView Fix Column Width", 400, 300)
$hListView = GUICtrlCreateListView("Column 0|Column 1|Column 2|Column 3", 2, 2, 394, 268)
GUISetState()

; Prevent resizing of a specific column (0-based)
Global $iFix_Col = 1

GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY")

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

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

All clear? ;)

That is a very slick method, I like it.

BrewManNH,

Thanks. It took a fair bit of Googling and MSDN searching but the end result was worth it. I suppose it could be improved with the cursor not changing - but I will leave that to someone else. ;)

      Hello,
      Do you have any idea to resize Vector graphic using some maths trick?
      It's example to create Vector image 10x10px and write A
      Local $a10x10 = [ _ 1,1,1,1,1,1,1,1,1,1, _ 1,1,1,0,0,0,0,1,1,1, _ 1,1,0,0,1,1,0,0,1,1, _ 1,1,0,1,1,1,1,0,1,1, _ 1,1,0,1,1,1,1,0,1,1, _ 1,1,0,0,0,0,0,0,1,1, _ 1,1,0,1,1,1,1,0,1,1, _ 1,1,0,1,1,1,1,0,1,1, _ 1,0,0,0,1,1,0,0,0,1, _ 1,1,1,1,1,1,1,1,1,1 _ ] Local $oVector = ObjCreate("WIA.Vector.1") If Not IsObj($oVector) Then ConsoleWrite("+++ Error " & @error & " durning create a Vector.object." & @CRLF) Exit EndIf Local $iBlue = 0xFF0000FF ; ARGB color Local $iWhite = 0xFFFFFFFF ; adding pixels to vector For $i = 0 To UBound($a10x10) - 1 Local $iPixel = $a10x10[$i] Local $iColor = $iBlue If $iPixel = 0 Then $iColor = $iWhite $oVector.Add($iColor) Next ; create a img 10x10 px Local $oImg = $oVector.ImageFile(10, 10) ; path to file Local $sPath = @ScriptDir & "\Vector.bmp" ; delete previous file if exits. FileDelete($sPath) ; save img to script direction. $oImg.SaveFile($sPath) ; show result, you have to use 800% size to see effects. ShellExecute("Vector.bmp")

      Hi,

      Is it possible to set a different text direction/layout (not alignment) for a Listview column?
       
      Thanks.

      So trying to get an INI section in a listView with checkboxes. Was able to get the the section values to show until i add the checkboxes and now only the keys are show up. Between reading the Help file, Forum Topic and trying other code option. I have been unable to answer this problem. I'm assuming its something very basic I'm overlooking since this it's day 21 of learning Autoit.
      If someone could please advise I would appreciate the assistance.
       
      Here's the code: 
      #include <GUIConstantsEx.au3> #include <MsgBoxConstants.au3> #include <GUIListView.au3> #include <Array.au3> #include <File.au3> #include <ListViewConstants.au3> Global $sIniPath = "installLog.ini" ;ConsoleWrite($sIniPath) $iniSctionNames = IniReadSectionNames($sIniPath) ;_ArrayDisplay($iniSctionNames, "$iniSctionNames") $keys2 = IniReadSection($sIniPath, $iniSctionNames[2]) _ArrayDisplay($keys2 , "$keys2") ; Create GUI $hGUI = GUICreate("Test", 300, 250) ; Create ListView $cLV = GUICtrlCreateListView("", 10, 10, 200, 200,$LVS_List,$LVS_EX_CHECKBOXES) _GUICtrlListView_AddColumn($cLV, $keys2, 100) _GUICtrlListView_AddColumn($cLV, $keys2, 100) ;_GUICtrlListView_AddItem($cLV, $keys2, 0) _GUICtrlListView_AddArray($cLV, $keys2) GUISetState() While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd And the INI file I'm using.

      Hi all,
      I'm trying to create a listview with subitem icons and I achieved this by simply rearranging the order of the columns, so that the first column is in the middle, thus appearing as a subitem with an icon - this method prevents the "icon clipping" that happens when using subitem icons in a listview. My issue is that when I select a row that does not have an icon, the space where the icon would be is white. Is there a way to make this transparent, so it looks like the entire row is selected?
      Here's an example - click the second listview item/row to see a blank space where the icon would be.
      #include <GuiConstantsEx.au3> #include <GuiListView.au3> #include <GuiImageList.au3> #include <WindowsConstants.au3> _Main() Func _Main() Local $hGui, $listview, $hImage Local $iLV_EXStyle_NoChecks = BitOR($LVS_EX_GRIDLINES, $LVS_EX_FULLROWSELECT, $LVS_EX_SUBITEMIMAGES, $LVS_EX_DOUBLEBUFFER, $LVS_EX_HEADERDRAGDROP) $hGui = GUICreate("Listview Test With Icons", 400, 300) $listview = GUICtrlCreateListView("Col 1|Col 2|Col 3", 2, 2, 394, 268, BitOR($LVS_REPORT, $LVS_SHAREIMAGELISTS)) _GUICtrlListView_SetExtendedListViewStyle($listview, $iLV_EXStyle_NoChecks) GUISetState() ; Create the image list $hImage = _GUIImageList_Create(16, 16, 5, 3) _GUIImageList_AddIcon($hImage, @SystemDir & "\shell32.dll", 165) _GUICtrlListView_SetImageList($listview, $hImage, 1) ; Set the order so the first column is moved to the middle, ; acting like a subitem with an icon _GUICtrlListView_SetColumnOrder($listview, "1|0|2") ; Add the items GUICtrlCreateListViewItem("Item1|Item2|Item3", $listview) GUICtrlCreateListViewItem("Item4|Item5|Item6", $listview) ; Set an icon for just the first item _GUICtrlListView_SetItemImage($listview, 0, 0) Do Until GUIGetMsg() = $GUI_EVENT_CLOSE GUIDelete() EndFunc ;==>_Main
