How a ListView acts as CTRL was pressed by default?

9 posts in this topic

#1 ·  Posted (edited)

I want that the Listview acts as CTRL key was pressed by default to avoid any deletion when the listview was clicked.

Here an example code:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GUIListView.au3>

$hGUI = GUICreate("ListView Test", 400, 550)
$iLV = GUICtrlCreateListView("", 0, 10, 400, 480, $LVS_SHOWSELALWAYS, BitOR($LVS_EX_FLATSB, $LVS_EX_CHECKBOXES, $LVS_EX_FULLROWSELECT, $LVS_EX_DOUBLEBUFFER))
_GUICtrlListView_AddColumn($iLV, "Date", 100, 1)
_GUICtrlListView_AddColumn($iLV, "Size (bytes)", 100, 1)
_GUICtrlListView_AddColumn($iLV, "File Name", 100, 1)
For $i = 0 to 150
    _GUICtrlListView_AddItem($iLV, "Row " & $i)
    _GUICtrlListView_AddSubItem($iLV, $i, $i * 2, 1)
    _GUICtrlListView_AddSubItem($iLV, $i, $i * 4, 2)
Next

$cButton = GUICtrlCreateButton("Reset", 10, 510, 80, 30)

GUISetState()
_GUICtrlListView_SetItemChecked($iLV, 0)
_GUICtrlListView_SetItemSelected($iLV, 0)

_GUICtrlListView_SetItemSelected($iLV, 1)
_GUICtrlListView_SetItemChecked($iLV, 2)
_GUICtrlListView_SetItemSelected($iLV, 2)

EndFunc   ;==>_DebugPrint

Just cklick the listview and you will see that the selection is deleted. Repeat it and hold the CTRL key pressed.

Any ideas?

I don't want to read the listview and check whether the checkbox is checked and mark the row appropriately! It's lagging...

UEZ, May be you can use something like this:

LarsJ,

interesting idea to simulate the CTRL key behavior which didn't came to my mind although I used  $NM_CUSTOMDRAW to draw the grid in different color.  :thumbsup:

Just for my curiosity: is there a way without simulating? How is windows handling the lv when ctrl is pressed?

Thanks!

Br,

UEZ

LarsJ,

Another nice script. :thumbsup:

But could I make 2 suggested changes?

- 1. When adding extended styles to a ListView it is always advisable to use _GUICtrlListView_SetExtendedListViewStyle as some of these values are also used by $WS_Ex_* styles and can be confused with them. That is why the function exists. ;)

- 2. In ListViews created with the native function, AutoIt uses the item parameter to store the internal ControlID of the row. As explained in the Help file, it is best to use parameter values well above any possible existing ControlIDs (we recommend 1000+) as experience has shown that there can be "ghost" effects on the real control if this is not done. In this case you are only using True/False (1/0) and so there is no real possibility of this happening, but I raise it a useful hint for anyone reading. :)

Making those changes does not affect the script as you can see here (I use 1000/1001 as checked/unchecked):

At first glance it looks like what I want BUT it doesn't work when you have checkboxes and mark checked and unmark unchecked rows in the list view.
Only rows with checked checkboxes should be selected using _GUICtrlListView_SetItemSelected().


Is it possible in this section

...
                            If $wParam = $iListView_Web Then
                                Local $lItemlParam = $tNMLVCUSTOMDRAW.lItemlParam ; Item param
                                Local $iSubItem = $tNMLVCUSTOMDRAW.iSubItem ; Subitem index
                                Local $uItemState = $tNMLVCUSTOMDRAW.uItemState ; Item state

                                If $lItemlParam Then ; Checked rows
                                    If Not BitAND($uItemState, $CDIS_FOCUS) Then
                                        DllStructSetData($tNMLVCUSTOMDRAW, "ClrText", $iColor_Text) ; Forecolor white
                                        DllStructSetData($tNMLVCUSTOMDRAW, "clrTextBk", 0x00FF00) ;0xFF9933) ; Backcolor blue, BGR
                                    EndIf
                                Else ; Other rows
                                    If Not BitAND($uItemState, $CDIS_FOCUS) Then
                                        DllStructSetData($tNMLVCUSTOMDRAW, "ClrText", $iColor_Text)
                                        DllStructSetData($tNMLVCUSTOMDRAW, "ClrTextBk", 0x0000FF) ;$iColor_LV)
                                    EndIf
                                EndIf
                            EndIf
...

to set the background color only for checked rows?


Edit: seems that $CDIS_CHECKED, $CDIS_SELECTED, $CDIS_MARKED are doing partly the job. Continuing to test and search for a solution...


Btw, is there a way to get the color which the system uses to mark a row in LV? -> _WinAPI_GetSysColor($COLOR_HIGHLIGHT)


Forget it, it was my wrong implementation which caused the problems.

One important thing. Because a row is drawn only in one color, the row should be drawn in the item part of the drawing stage, where the entire row is drawn at once. To draw such a row column by column in the subitem part is wrong, and leads to bad performance.

Here the rows are drawn in the item part of the drawing stage. The subitem part is deleted. A controlID offset with a value of 1000 is added to ItemParam.

Thanks LarsJ.
 
One question how would you implement multi selection? I mean if you change $NM_CLICK to $NM_DBLCLK and select some rows by holding down the shift key. These lines should be marked and the checkbox should be set.

The same when unselecting some lines.
 

This is what I did:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GUIListView.au3>


Global Const $iColor_TextBk = _WinAPI_GetSysColor($COLOR_HIGHLIGHT)
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GUIListView.au3>

$hGUI = GUICreate("ListView Test", 400, 550)
$iLV = GUICtrlCreateListView("", 0, 10, 400, 480, $LVS_SHOWSELALWAYS)
_GUICtrlListView_SetExtendedListViewStyle($iLV, BitOR($LVS_EX_FLATSB, $LVS_EX_CHECKBOXES, $LVS_EX_FULLROWSELECT, $LVS_EX_DOUBLEBUFFER))

_GUICtrlListView_AddColumn($iLV, "Date", 100, 1)
_GUICtrlListView_AddColumn($iLV, "Size (bytes)", 100, 1)
_GUICtrlListView_AddColumn($iLV, "File Name", 100, 1)
For $i = 0 To 150
    _GUICtrlListView_AddItem($iLV, "Row " & $i)
    _GUICtrlListView_SetItemParam($iLV, $i, 1000)
    _GUICtrlListView_AddSubItem($iLV, $i, $i * 2, 1)
    _GUICtrlListView_AddSubItem($iLV, $i, $i * 4, 2)
Next
_GUICtrlListView_SetItemChecked($iLV, 0)
_GUICtrlListView_SetItemParam($iLV, 0, 1001)
_GUICtrlListView_SetItemChecked($iLV, 1)
_GUICtrlListView_SetItemParam($iLV, 1, 1001)

      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. Do Until GUIGetMsg() = $GUI_EVENT_CLOSE GUIDelete() EndFunc ;==>Example Func _GUICtrlListView_GetColumnID_ByName($hListView, $sColumnToFind) Local $iColumn_Count = _GUICtrlListView_GetColumnCount($hListView) Local $aColumns For $iColumn_idx = 0 To $iColumn_Count - 1 $aColumns = _GUICtrlListView_GetColumn($hListView, $iColumn_idx) If $aColumns[5] = $sColumnToFind Then Return $iColumn_idx EndIf Next Return SetError(1, 0, -1) EndFunc ;==>_GUICtrlListView_GetColumnID_ByName

      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):

      Thank you in advance!
      P.S.
      The script is patched from different scripts of different users in the forum - thank you again users!

      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:
      Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam) #forceref $hWnd, $iMsg, $iwParam, $ilParam Local $hWndFrom, $iCode, $tNMHDR $tNMHDR = DllStructCreate($tagNMHDR, $ilParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iCode = DllStructGetData($tNMHDR, "Code") Switch $hWndFrom Case $hListView Switch $iCode Case $NM_CUSTOMDRAW Local $iDrawStage, $tCustDraw $tCustDraw = DllStructCreate($tagNMLVCUSTOMDRAW, $ilParam) $iDrawStage = DllStructGetData($tCustDraw, 'dwDrawStage') Switch $iDrawStage Case BitOR(0, $CDDS_ITEMPREPAINT) ;, $CDDS_SUBITEM) setItemColor($tCustDraw, $hWndFrom) Return $CDRF_NOTIFYSUBITEMDRAW EndSwitch EndSwitch EndSwitch Return $GUI_RUNDEFMSG EndFunc ;==>WM_NOTIFY Func setItemColor($tCustDraw, $hWnd) Local $iIndex, $color, $iSubitem $iIndex = DllStructGetData($tCustDraw, 'dwItemSpec') ; item number $color = _GUICtrlListView_GetItemParam($hWnd, $iIndex) $iSubitem = DllStructGetData($tCustDraw, 'iSubItem') ; Here, I want to only change the color of the 3rd col, and not the 1st and 2nd cols DllStructSetData($tCustDraw, 'iSubItem', 2) ; always use the 3rd column (the 'sample' col) logmsg("+++: setItemColor($tCustDraw, 0x" & Hex($hWnd) & ") entered ... " _ & ", $iIndex = " & $iIndex & ", $iSubItem = " & $iSubitem & ", $color = " & Hex($color)) DllStructSetData($tCustDraw, 'clrText', $color) ; set the Text color DllStructSetData($tCustDraw, 'clrTextBk', bitnot($color)) ; set the background color EndFunc ;==>setItemColor Func logmsg($msg, $lnum = @ScriptLineNumber) ConsoleWrite("+++:" & $lnum & ": " & $msg & @CRLF) EndFunc ;==>logmsg
