Listview in Tab

19 posts in this topic

After >JohnMcloud showing me how to select individual items in a listview earlier, I've been pulling my hair out trying to get it to work in my own script for quite a while.

I finally discovered the problem was occurring because the listview was on a tab item.

The symptoms are:

You have to click on the selection you want, and then the one above it, for the actuall selection to happen.

I'd love some help on this. I've created a reproducer, below...

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

Global $hGUI, $hListview, $aHit[2] = [-1, -1]

$hGUI = GUICreate("Listview in TAB", 250, 180)

GUISetBkColor(0x00E0FFFF)
GUISetFont(9, 300)

Local $idTab = GUICtrlCreateTab(0, 0, 250, 130)

GUICtrlCreateTabItem("tab")

$iListview = GUICtrlCreateListView("one|two|three", 0, 20, 350, 130, $LVS_REPORT, BitOR($LVS_EX_GRIDLINES, $LVS_EX_FULLROWSELECT))
$hListview = GUICtrlGetHandle($iListview)
GUICtrlCreateListViewItem("0-0|0-1|0-2", $iListview)
GUICtrlCreateListViewItem("1-0|1-1|1-2", $iListview)
GUICtrlCreateListViewItem("2-0|2-1|2-2", $iListview)
GUICtrlCreateTabItem("")

$hButton = GUICtrlCreateButton("Click", 0, 155, 250, 20)

GUISetState(@SW_SHOW)
GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")

I'am not sure, but maybe this:

;~                         $aInfo = _GUICtrlListView_SubItemHitTest($hListview, $aInfo[0] - 2, $aInfo[1] - 2) ; Upper left = ( 2, 2 )
                        $aInfo = _GUICtrlListView_SubItemHitTest($hListview, -1, -1) ; Upper left = ( 2, 2 )

The problem is that you are not selecting a cell explicitly. Your code will work till you select a cell and not mark a row only -> not tab related!

Try this:

Switch $iCode
                Case $NM_CLICK
                    $tInfo = DllStructCreate($tagNMITEMACTIVATE, $lParam)
                    $aHit[0] = $tInfo.Index
                    $aHit[1] = $tInfo.SubItem
                Case $LVN_ITEMCHANGED

You have to check your code in the WM_NOTIFY function -> $LVN_ITEMCHANGED and $NM_CUSTOMDRAW.

If you disable those check it will work properly but you have no explicitly cell selection.

J1,

This works for me...

<code deleted>

To recolor the items I believe you have to loop back throught the listview, not sure though...

Have you seen M23's listview UDF?  I think it's called _GuiCtrlListViewEX...

Then the correct item is returned, but obviously no selection is shown.

I'm looking at the code in that block for a while, but my head is just spinning.

Maybe here you can find your hints

JohnOne,

You need to set the correct coordinates of your ListView in this line:

$aInfo = _GUICtrlListView_SubItemHitTest($hListview, $aInfo[0] - 2, $aInfo[1] - 20) ; Upper left = ( 2, 20 )
As you still had the coordinates of the other example it was not giving you the correct return in $aHit. ;)
