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.


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.

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. ;)

      I was not lucky to find the right function so I created it by my self:
      _GUICtrlListView_GetColumnID_ByName()
      Example:
       
      #include <GUIConstantsEx.au3> #include <GuiListView.au3> #include <MsgBoxConstants.au3> Example() Func Example() GUICreate("ListView Get Column ID", 400, 300) Local $idListview = GUICtrlCreateListView("Alfa|Beta|Gama", 2, 2, 394, 268) GUISetState(@SW_SHOW) _GUICtrlListView_SetColumnOrder($idListview, "2|0|1") MsgBox($MB_SYSTEMMODAL, "Information", "Column ID: " & _GUICtrlListView_GetColumnID_ByName($idListview, 'Gama')) ; Loop until the user exits.

      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 cannot be downloaded although they are visible on the web site!
       
      Here the download link of the source code only: AutoIt Sysinternal Tools Synchronizer v0.99.1 build 2017-10-23 beta.7z  (1353 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.

      Ahoy Autoit Community!
      After many trials and errors I am unable to solve a problem I am facing and would appreciate any kind of input or better yet a solution 
      The Premise: An embeded slideshow viewer that runs after double-clicking an item in a ListView (each item will generate a different slideshow images).
      The Setup: GUI with a ListView Control and a simple exit button.
      The Issue: Once double clicked the slide plays however the GUI "locks"/non responsive until the slide is over. Same thing if I click on the "Test" button.
      The Culprit: I believe since it's in the images loop it can't accept any other commands until that loop is over.
      The Wish: I want to be able to use the GUI functions (selecting other items, clicking on button etc.) while the slideshow plays.
      The Code (stripped and simplified as much as I could):
      #include <GuiListView.au3> #include <File.au3> #include <GDIPlus.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> Opt("GUIOnEventMode", 1) HotKeySet("{Esc}", "_Exit") Global $c=0 Global $ssGDI[3], $ssGraphic[2], $ssImage Global Const $bg_color = "000000" Global Const $ssW = 480, $ssH = 320 Global $aFiles = _FileListToArrayRec("d:\testStage\", "*.jpg;*.png;*.bmp;*.gif;*.JPG;*.PNG;*.BMP;*.GIF", $FLTAR_FILES, $FLTAR_NORECUR ,$FLTAR_SORT ,$FLTAR_FULLPATH ) $guiW = 1200 $guiH = 726 $mainWindow = GUICreate("Slideshow Viewer", $guiW, $guiH, -1, -1, $WS_POPUP) $Button1 = GUICtrlCreateButton("Exit", 0, 0, 50, 50) GUICtrlSetOnEvent($Button1, "_Exit") $Button1 = GUICtrlCreateButton("Test", 60, 0, 50, 50) GUICtrlSetOnEvent($Button1, "Test") Global $ListView = GUICtrlCreateListView("Entry Name|Category", 5, 75, 195, 280) _GUICtrlListView_SetColumnWidth ($ListView, 0, 100) _GUICtrlListView_SetColumnWidth ($ListView, 1, 100) GUICtrlSendMsg($ListView, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_GRIDLINES, $LVS_EX_GRIDLINES) GUICtrlSendMsg($ListView, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_FULLROWSELECT, $LVS_EX_FULLROWSELECT) GUICtrlCreateListViewItem("Name 1|Category 1", $ListView) GUICtrlCreateListViewItem("Name 2|Category 2", $ListView) screenshotWidgetInit($ssW,$ssH, 690, 100) GUISetState(@SW_SHOW, $mainWindow) GUIRegisterMsg($WM_NOTIFY, "WM_Notify_Events") While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE _Exit() EndSwitch WEnd Func Test() For $k = 1 To UBound($aFiles) - 1 screenshotWidgetTransition($aFiles[$k]) Next EndFunc Func ListView_Click() ConsoleWrite("Left Click") EndFunc Func ListView_DoubleClick() ConsoleWrite("Double Left Click") Test() EndFunc Func WM_Notify_Events($hWndGUI, $MsgID, $wParam, $lParam) #forceref $hWndGUI, $MsgID, $wParam Local $tagNMHDR, $event, $hwndFrom, $code $tagNMHDR = DllStructCreate("int;int;int", $lParam) If @error Then Return $event = DllStructGetData($tagNMHDR, 3) Select Case $wParam = $ListView Select Case $event = $NM_CLICK ListView_Click () Case $event = $NM_DBLCLK ListView_DoubleClick () EndSelect EndSelect Return $GUI_RUNDEFMSG EndFunc Func screenshotWidgetTransition($image, $delay = 0, $speed = 1, $sleep = 2000) Local $a, $d = $c, $iX, $iY $ssImage = _GDIPlus_ImageLoadFromFile($image) $iX = _GDIPlus_ImageGetWidth($ssImage) $iY = _GDIPlus_ImageGetHeight($ssImage) $FDesktop=$ssH/$ssW $Fact =1 If $iX > $ssW And $FDesktop > ($iY/$iX) Then $Fact=$ssW/$iX ElseIf $iY > $ssH Then $Fact=$ssH/$iY EndIf $H1 = Round(($Fact * $iY),0) $W1 = Round(($Fact * $iX),0) _GDIPlus_GraphicsDrawImageRect($ssGraphic[$d], $ssImage,($ssW - $W1)/2, ($ssH - $H1) / 2,$W1,$H1) WinSetTrans($ssGDI[$d], "", 0) WinSetOnTop($ssGDI[$d], "", 1) For $a = 0 To 254 Step $speed WinSetTrans($ssGDI[$d], "", $a) Sleep($delay) Next WinSetTrans($ssGDI[$d], "", 254) WinSetOnTop($ssGDI[Not ($d)], "", 0) WinSetTrans($ssGDI[Not ($d)], "", 0) _GDIPlus_GraphicsClear($ssGraphic[Not ($d)]) $c = 1 - $d _GDIPlus_ImageDispose ($ssImage) ; very important to realease the pics Sleep($sleep) EndFunc ;==>screenshotWidgetTransition Func screenshotWidgetInit($ssW,$ssH,$ssX,$ssY) $ssGDI[2] = GUICreate("", $ssW, $ssH, $ssX, $ssY, $WS_POPUP, $WS_EX_MDICHILD, $mainWindow) $ssGDI[0] = GUICreate("", $ssW, $ssH, 3, 3, $WS_POPUP, $WS_EX_MDICHILD, $ssGDI[2]) $ssGDI[1] = GUICreate("", $ssW, $ssH, 3, 3, $WS_POPUP, $WS_EX_MDICHILD, $ssGDI[2]) ; GUISetBkColor("0x" & $bg_color, $ssGDI[2]) GUISetState(@SW_SHOW, $ssGDI[2]) GUISetState(@SW_SHOW, $ssGDI[0]) GUISetState(@SW_SHOW, $ssGDI[1]) WinSetTrans($ssGDI[0], "", 0) WinSetTrans($ssGDI[1], "", 0) _GDIPlus_Startup() $ssGraphic[0] = _GDIPlus_GraphicsCreateFromHWND($ssGDI[0]) $ssGraphic[1] = _GDIPlus_GraphicsCreateFromHWND($ssGDI[1]) _GDIPlus_GraphicsClear($ssGraphic[0], "0xFF" & $bg_color) _GDIPlus_GraphicsClear($ssGraphic[1], "0xFF" & $bg_color) EndFunc ;==>screenshotWidgetInit Func _Exit() _GDIPlus_ImageDispose($ssImage) _GDIPlus_GraphicsDispose($ssGraphic[0]) _GDIPlus_GraphicsDispose($ssGraphic[1]) GUIDelete($ssGDI[0]) GUIDelete($ssGDI[1]) GUIDelete($ssGDI[2]) _GDIPlus_Shutdown() Exit EndFunc ;==>_Exit I hope someone can shed light on this; perhaps a different approach is needed?

      I know there are listbox and listview, but now I have?
      here is the video of infowindow 
      I tried to read mouse selection like for listbox:
      $listWindow = "[CLASS:TFormResearchGR]" $topicsList = "[CLASS:TMWrapper; INSTANCE:255]" WinWait($listWindow, "", 60) $hdlWindow = WinGetHandle($listWindow) $hdlList = ControlGetHandle($hdlWindow, "", $topicsList) _GUICtrlListBox_ClickItem($hdlList, 0, "left") $countOfList = _GUICtrlListBox_GetCount($hdlList) ConsoleWrite("Count of list: " & $countOfList & @LF) count of list is not working.
      I realiezed that there are difference between listbox and listview, but this is something different.
      and till now I never saw that you can go inside with infotool and also get instances.
       
      so Im confused how to get the list number and the names of selection?

      I have a listview with 3 columns and I want to set the 3rd column's color based on the item's 'Param' value, but even though I set up for the 3rd column, the entire row always gets the color.
      My test code is below, but here is the pertinent code:
