If I change nHeadBmpNo how do I repaint the header?

oCol:bLClickHeader := {|r,c,f,o| IIF( oCol:nHeadBmpNo = 2, oCol:nHeadBmpNo := 1 ,oCol:nHeadBmpNo := 2 ) )) }
PaintHeader??
Thanks in advance
Otto

Thank you for your help.

The line

oCol:oxBrw:Refresh()

causes an error. I don't find out what is wrong.

Otto,

Try:

oCol:oBrw:Refresh()

Hello Antonio,
thank you. I see the msgInfo correctly but the changes of the bmp are not visible.

oCol:AddBmpHandle( FwBmpAsc() )
oCol:AddBmpHandle( FwBmpDes() )
oCol:nHeadBmpNo := 1
oCol:bLClickHeader := {|r,c,f,o| IIF( oCol:nHeadBmpNo = 2, (oCol:nHeadBmpNo := 1 ,msginfo(1)),(oCol:nHeadBmpNo := 2,msginfo(2) )),oCol:oBrw:Refresh(),msginfo("test") }

Could you please extend the testxbrw.prg
to show how
oCol:nHeadBmpNo =

should be used.

Suggestion:
I would comment for the standard sample ADS out - for a beginner the error this causes is no so easy to find out.
You should also reindex customer automatically. Otherwise the incremental search gives an error.

Otto

Otto,

You may use:
METHOD PaintHeader( nRow, nCol, nHeight, lInvert, hDC ) CLASS TXBrwColumn

METHOD PaintHeader( nRow, nCol, nHeight, lInvert, hDC ) CLASS TXBrwColumn

Isn't this called by HeaderLButtonDown?

METHOD HeaderLButtonDown( nMRow, nMCol, nFlags ) CLASS TXBrwColumn

if ::oBrw:nCaptured == 0 .and. ::oBrw:lAllowColSwapping
::oBrw:oCapCol := Self
::oBrw:nCaptured := 1
::oBrw:Capture()
::PaintHeader( 2, nil, ::oBrw:nHeaderHeight - 3, .t. )
endif

return nil

METHOD PaintHeader( nRow, nCol, nHeight, lInvert, hDC ) CLASS TXBrwColumn

Otto,

> Isn't this called by HeaderLButtonDown?

Yes

Otto,

In samples\TestXBrw.prg, STATIC FUNCTION Bitmaps( oWnd ):

oCol := oBrw:AddCol()
oCol:AddResource( "CLIP" )
oCol:AddResource( "star" )
oCol:bLClickHeader = { | nMRow, nMCol, nFlags, Self | If( ::nHeadBmpNo == 2, ::nHeadBmpNo := 1, ::nHeadBmpNo := 2 ), ::oBrw:Refresh() }

And add this to TestXBrw.rc:
STAR BITMAP "../bitmaps/16x16/favorite.bmp"

I did it this way. But the header does not change.
Regards,
Otto
