MikeA Posted September 11, 2007 Share Posted September 11, 2007 In releases as far back as 3.2.6.0 at least, on Windows XP, if I use the up or down scroll buttons or click in the scroll bar to move up or down in a ListView with gridlines, the ListView display becomes "garbled" (see the attached screen capture). This does not happen when I use the slider button to scroll. In fact, using the slider button will "clean up" the garbled ListView display. This issue does not occur on Vista. I haven't tested it on any other OS. Link to comment Share on other sites More sharing options...

Zedna Posted September 11, 2007 Share Posted September 11, 2007 I think problem is with GUISetFont(9, Default, Default, "Tahoma") GUICtrlSetFont($ShareList, 8.5) but here must help you somebody more experienced Resources UDF ResourcesEx UDF AutoIt Forum Search Link to comment Share on other sites More sharing options...
Siao Posted September 11, 2007 Share Posted September 11, 2007 (edited) Ya, these gridlines are glitchy, about any script works as an example...Lets say#include <GUIConstants.au3> GUICreate("listview items",220,200) $listview = GUICtrlCreateListView ("col1 |col2",10,10,200,150,-1,$LVS_EX_GRIDLINES) Dim $aLVItm[16] For $i = 1 to 15 $aLVItm[$i]=GUICtrlCreateListViewItem("item"&$i,$listview) Next GUISetState() While GUIGetMsg() <> $GUI_EVENT_CLOSE WEndIf I scroll down using methods MikeA mentioned, I get this:No gridlines for any of the items that come into view. Dragging the scroll button or mouse scrolling works OK.And I remember getting that garbled view in one of my programs too, probably I used custom Font settings just like OP.v3.2.4.9 Edited September 11, 2007 by Siao "be smart, drink your wine" Link to comment Share on other sites More sharing options...

ReFran Posted September 11, 2007 Share Posted September 11, 2007 (edited) It's the some behavior with a simple, but long Listview for me (WinXP). If I scroll the LV it has a repain problem. I think that is a generell problem/challenge/bug with the built-in LV. In a disussion with Mr. Gafrost about drag'n drop inside a LV, where also a repain problem occurs, if the LV is scrolled, he stated: ... "Also found out that if you use the Built-in ListView then there is the repain problem in using the DragImage, didn't see that problem with Creating your own ListView." ... Creating my own Listview is far about my level, but Au3Lib can create a own Listview. So perhaps someone may test, if that works.

ReFran Posted September 12, 2007 Share Posted September 12, 2007 (edited) So perhaps someone may test, if that works. It's the same behavoir with a Au3Lib created Listview. After scrolling it gets a repain problem. So it seems, there is a bug. Or? br, Reinhard #include <A3LListView.au3> Global $hGUI, $hList ; Create GUI $hGUI = GUICreate("ListView", 400, 300) $hList = _ListView_Create($hGUI, 2, 2, 394, 268) _ListView_SetExtendedListViewStyle($hList, BitOR($LVS_EX_FULLROWSELECT, $LVS_EX_GRIDLINES)) GUISetState() ; Add columns _ListView_InsertColumn($hList, 0, "Column 1", 100) _ListView_InsertColumn($hList, 1, "Column 2", 100) _ListView_InsertColumn($hList, 2, "Column 3", 100) for $i=0 to 30 _ListView_AddItem ($hList, "Row "&$i &": Col 1", $i) _ListView_AddSubItem($hList, $i, "Row "&$i &": Col 2", 1) _ListView_AddSubItem($hList, $i, "Row "&$i &": Col 3", 2) next ; Loop until user exits do until GUIGetMsg() = $GUI_EVENT_CLOSE Edited September 12, 2007 by ReFran Link to comment Share on other sites More sharing options...
smashly Posted September 13, 2007 Share Posted September 13, 2007 Hi, I noticed the the listview problem back when I dl'd the ApiConstants gui from the downloads section of the forum. If I scroll using the down arrow on the scroll bar then the lines become all screwwed up, but if I use the scrollbar slider button or the scrollbar up button then the graphics glistch is not there.. I just never looked to deeply into it.. Good to see it's not just my configuration of software that has this glitch Cheers Link to comment Share on other sites More sharing options...
