Deleting listviewitem leaves a black space

[er453r]

Hi. My ListView has $LV_VIEW_TILE style. When I try to delete items from it (with _GUICtrlListViewDeleteItem) they are deleted, but the space after the deleted item is not filled. It just disappears, and leaves a black place. Any ideas?

I've tried to delete all items, and redraw the whole list, but it takes too long. Thanks in advance.

Some code would prompt a reply quicker I'm guessing.

There's little coding here... but with pictures

We have a ListView:

Now:

_GUICtrlListViewDeleteItem($list,2)

Effect:

Hope it helps.

Being there is no script to look at, we'll have to guess.

Try

GuiSetState(@SW_LOCK)

before the delete and

GuiSetState(@SW_UNLOCK)

after the delete

if this don't work

you might want to look at the beta, and do something like

_GUICtrlListView_BeginUpdate

_GUICtrlListView_DeleteItem

_GUICtrlListView_EndUpdate

look at _GuiCtrlListView_SetItemPosition in beta

Tile/Icon view doesn't re-arrange the items automatically as far as I know

might also look at _GUICtrlListView_Arrange

on a roll here, won't re-arrange automatically unless you have $LVS_AUTOARRANGE style set

Ok, beta does wonders. BUT it doesn't support $LV_VIEW_TILE style

_GUICtrlListView_SetView($listview, 4)

Found it myself at least... Thanks for all the help

edit: maybe one more thing. Is it possible to change the tile icon size?

ok, managed myself

And is it possible to change font in listview?

And is it possible to change font in listview?

here's what sets the font of the UDF created listview

_SendMessage($hList, $WM_SETFONT, _WinAPI_GetStockObject ($DEFAULT_GUI_FONT), True)

if your using the GuiCtrlCreateListview, might look at GUICtrlSetFont

_SendMessage($hList, $WM_SETFONT, _WinAPI_GetStockObject ($DEFAULT_GUI_FONT), True)

Hm. And which part corresponds to size/weight?

And I'm using betas

_GUICtrlListView_Create

_GUICtrlListView_Create

_SendMessage($hList, $WM_SETFONT, _WinAPI_GetStockObject ($DEFAULT_GUI_FONT), True)

_WinAPI_GetStockObject ($DEFAULT_GUI_FONT) gets the handle to the default gui font.

the $WM_SETFONT message takes a handle to a font.

_WinAPI_CreateFontIndirect and $tagLOGFONT is what you need, the $tagLOGFONT isn't listed in the help at the moment, should be soon, but you can find it in the StructureConstants.au3 file

You'll also need to know how to do DllStruct functions

Thanks

[er453r]

And how can I control the resizing of the beta ListView?

Thanks, Gary.

Can you do it for us, then it won't end up in a mess like this:

expandcollapse popup

#include <GUIConstants.au3>
#Include <GuiListView.au3>

Opt("GUIOnEventMode", 1)
$Form1 = GUICreate('testing', 767, 452, 193, 115, BitOR($WS_MAXIMIZEBOX,$WS_MINIMIZEBOX,$WS_SIZEBOX,$WS_THICKFRAME,$WS_SYSMENU,$WS_CAPTION,$WS_OVERLAPPEDWINDOW,$WS_TILEDWINDOW,$WS_GROUP,$WS_TABSTOP,$WS_BORDER,$WS_CLIPSIBLINGS), 0)
GUISetOnEvent($GUI_EVENT_CLOSE, "Form1_Close")
$LV1h = _GUICtrlListView_Create($Form1, '', 0, 0, 766, 390, _
                BitOR($LVS_REPORT, $LVS_SINGLESEL, $LVS_SHOWSELALWAYS, $WS_VSCROLL, $WS_CHILD, $WS_VISIBLE))
_GUICtrlListView_SetExtendedListViewStyle($LV1h, BitOR($LVS_EX_GRIDLINES,$LVS_EX_HEADERDRAGDROP, $WS_EX_CLIENTEDGE))

_GUICtrlListView_AddColumn($LV1h, 'Name', 230, 2)
_GUICtrlListView_AddItem($LV1h, 'Gemma Atkinson')
_GUICtrlListView_AddItem($LV1h, 'Jason "J" Brown')

GUISetState(@SW_SHOW)

_SetFont_hWnd($LV1h, 12.5, 400, 2, 'Lucida Console')
