Listview Item Without Icon Shows Empty Space

Recommended Posts

buymeapc

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

snip. don't know. your requirements seem weird to me. why can't everyone have an icon? even just a '-' character?

I see no clipping in the example that you got your code from in the Help file

It's going to be a list of applications which will have a column for updates that are available. If there's an update available, it shows a 'new' icon with the new version. If no update is necessary, it's just an empty subitem. And if an item with no updates available is selected, it just looks weird with this white square in the subitem. I was hoping there was some trick to make it blend in.

I've attached an image where I've selected the item without an icon and it shows the 'placeholder' where an icon would be as a white square - it just looks weird to me.

I kind of like it, like a tree node. but I hope you can make it transparent. good luck. there are other gui and color wizards around here than me for that.

I placed a white icon and it looks like this

You might use a dirty workaround... create a zero-width column 0 and set it at the last column position

#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 end
    _GUICtrlListView_SetColumnWidth($listview, 0, 0)
    _GUICtrlListView_SetColumnOrder($listview, "1|2|3|0")

    ; 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, 2)

 
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
    GUIDelete()
EndFunc   ;==>_Main

      I am tracking this topic by @LarsJ.  It is very advanced and overkill for what I am currently trying to do.
       
      Problem is this.
      Listview contains columns, one of which is right aligned and gets populated by float values, such as 123.99.  Some do not have decimals ie 124.00 and on sort gets truncated to 124.  Its obviously still the same value, but the display has reset.
      ; line below is for list VIEW ;..................................0.........1......2............ $cListView = GUICtrlCreateListView("CUSTOMER|AMOUNT|DESCRIPTION", 8, 152, 764, 279) GUICtrlSetBkColor($cListView, $GUI_BKCOLOR_LV_ALTERNATE) ; alternate between the listview background color and the listview item background color GUICtrlSetBkColor($cListView, $LVStdClr) ; Set the background color for the listview _GUICtrlListView_SetColumnWidth($cListView, 0, 120) ; -- the client name _GUICtrlListView_SetColumnWidth($cListView, 1, 90) ;-- the amount _GUICtrlListView_JustifyColumn($cListView, 1, 1) ; 1 - Text is right aligned _GUICtrlListView_SetColumnWidth($cListView, 2, 200) ; the description What I am looking for is something native and simple like a 
          _GUICtrlListView_SetColumnFormat($cListView, 1, "%.2f") ;  1 - column is stringformatted to "%.2f"
      So that after each sort it will appear as it was in the original rendering.
      Is there something like this? I have not been able to find a simple solution.

      Thanks.
