TBITMAP with SCROLL Problem.
Posted: Fri Nov 13, 2009 09:51 PM

Hi,

I have realized that when I use the SCROLL scope in TImage derived from TBitmap and click the scroll buttons it behaves strange. When I click Vertical scroll, Bitmaps moves horizontal. When I click Horizontal scroll, Bitmaps moves vertical.

Is there any more setting in scroll?

Thanks in advance.

Hi Rao,

As I said before I prepared a sample. It works fine in a standalone prg. But it does not work in my program.

But I am able to reproduce your problem in this small program

Code (fw): Select all Collapse

#include "FiveWin.ch"

function Main()

LOCAL oDlg, obmp

   DEFINE DIALOG oDlg  SIZE 400, 500 TRANSPARENT

   @ 10,10 IMAGE oBmp OF oDlg PIXEL ;
      FILE '\fwh\bitmaps\olga1.jpg' SCROLL ;
      SIZE 150,212 Update

   ACTIVATE DIALOG oDlg CENTERED

return nil

Seems to be a bug

i also found out that if the DIALOG is TRANSPARENT the scrollbars are behaving wrongly.

If the dialog is NOT TRANSPARENT, the scroll bars are behaving correctly

Exactly, You are right. It is related with dialogs Transparent clause.

Hakan, Rao,

Already fixed. It was a little bug in Class TBitmap

In both calls to TransBmp(), simply swap ::nX with ::nY:

Code (fw): Select all Collapse

                  TransBmp( ::hBitmap, ::nWidth(), ::nHeight(), nZeroZeroClr, ::hDC,;
                            ::nY, ::nX, ::nWidth(), ::nHeight() )

This fix is included in next FWH 9.11 build

regards, saludos
