Scrollbars

[Nicolai Kuntze]

Hi,
I have played with my continuing bug (#2302) but I have some problems 
understanding the meaning of the output:

fixme:win:GetWindowModuleFileNameA GetWindowModuleFileNameA(hwnd 
0x40032, lpszFileName 0x40670548, cchFileNameMax 80) stub!
trace:scroll:SetScrollInfo hwnd=0x10074 nBar=1 info=0x406715d4, 
bRedraw=1
trace:scroll:SCROLL_SetScrollInfo hwnd=0x10074 bar=1 mask=4 pos=1
trace:scroll:SCROLL_SetScrollInfo curVal=0 nPos=1
trace:scroll:SCROLL_SetScrollInfo new values: page=1 pos=0 min=0 max=0
trace:scroll:SCROLL_SetScrollInfo hide or disable
trace:scroll:SCROLL_ShowScrollBar hwnd=0x10074 bar=1 horz=0, vert=0
trace:scroll:SetScrollInfo hwnd=0x10074 nBar=1 info=0x406715d4, 
bRedraw=1
trace:scroll:SCROLL_SetScrollInfo hwnd=0x10074 bar=1 mask=4 pos=2
trace:scroll:SCROLL_SetScrollInfo curVal=0 nPos=2
trace:scroll:SCROLL_SetScrollInfo new values: page=1 pos=0 min=0 max=0
trace:scroll:SCROLL_SetScrollInfo hide or disable
trace:scroll:SCROLL_ShowScrollBar hwnd=0x10074 bar=1 horz=0, vert=0
trace:scroll:SetScrollInfo hwnd=0x10074 nBar=1 info=0x406715d4, 
bRedraw=1
trace:scroll:SCROLL_SetScrollInfo hwnd=0x10074 bar=1 mask=4 pos=3
trace:scroll:SCROLL_SetScrollInfo curVal=0 nPos=3
trace:scroll:SCROLL_SetScrollInfo new values: page=1 pos=0 min=0 max=0
trace:scroll:SCROLL_SetScrollInfo hide or disable
trace:scroll:SCROLL_ShowScrollBar hwnd=0x10074 bar=1 horz=0, vert=0

If my blue bar in the list disappears pos Value counts how many lines 
under the window I am. I have added a little debug to follow the source 
... From the developer I got the following snipplet:

int SViewLow::ViewSetScrollY( int PPos, int PMax, int PPage)
{
SCROLLINFO Scroll;
memset( &Scroll, 0, sizeof( Scroll));
Scroll.cbSize= sizeof( SCROLLINFO);
Scroll.fMask= 0;
if (PPos!=-1)
Scroll.fMask|= SIF_POS;
if (PMax!=-1)
Scroll.fMask|= SIF_RANGE;
if (PPage!=-1)
Scroll.fMask|= SIF_PAGE;
Scroll.nPos= PPos;
Scroll.nPage= PPage;
Scroll.nMax= PMax-1;
return SetScrollInfo( (HWND)ViewGetHWND(), SB_VERT, &Scroll, TRUE);
}
Does anyone has an idea what this could be?
Yours,
Nicolai
