Marco,

you can try to freeze the most left colums

Code: Select all  Expand view
oBrw:nFreeze := 2


or disable the the scrollbar

Code: Select all  Expand view
oBrw:lNoHScroll := .t.
kind regards
Stefan

Ok,
oBrw:nFreeze := 2
this line it's ok

Other solution
oBrw:lNoHScroll := .t.
creates this problem

I hope I don't create other problems in this way

wbrowse.prg

case nScrollCode == SB_PAGEDOWN
while nCol < Len( ::GetColSizes() ) .and. ;
(::IsColVisible( nCol ) .or. ::nColPos == nCol)
nCol++
end
IF ::lNoHScroll <> .T.
::nColPos := nCol
::nColAct := nCol
::oHScroll:SetPos( nCol )
::Refresh( .f. )
ENDIF

::lNoHScroll is an enhancement of tcbrowse, it does not exist in wbrowse. The problem is the HScroll() method of wbrowse, which is not overwritten in tcbrowse. As a workaround you can try to define your own method hscroll() in tcbrowse.

maybe like this (not tested)
Code: Select all  Expand view
METHOD HScroll (nWParam, nLParam) INLINE IIF (!::lNoScroll, super:HScroll(nWParam, nLParam), nil)
kind regards
