I insert on a folder a image
oImagen = TImage():Define(,"scaf.bmp" )
...

oGrid:adialogs[1]:bPainted := {|hDC| (PalBmpDraw( hDC, 0, 0, oImagen:hBitmap,, oGrid:adialogs[1]:nWidth, oGrid:adialogs[1]:nHeight,, .T.) ) }

and on this folder many btnbmp buttons with png file

@ nrow,ncol btnbmp oBtn[n] Filename aBmp[RA->RACOLORE] ;
SIZE nsizeW,nsizeh ;
Prompt str2lines(alltrim(Ra->Radesc)," ") ;
noborder CENTER;
font ofontsmall of oGrid:adialogs[1] ;
Action NIL

oBtn[n]:lTransparent:=.T.
oBtn[n]:oCursor:= cCursor







How you can see the buttons are not transparent ... why ?

Silvio,

it seems, Your images are NOT transparent ( white background ) ?

I can check them for You if You want

Can You check with my testbuttons ( premultiplied alpha ) ?
If You like it, I can create them with any color You need ( 3D - style )





My FOLDER-test.
Like You can see NO PROBLEM



@ 50, 50 BTNBMP oBtn[1] OF oFld1:aDialogs[3] ;
SIZE 70, 70 PIXEL TRANSPARENT ;
NOBORDER ;
FILENAME c_path1 + "Testbtn1.Png" ;
ACTION MsgAlert( "Buttontest" ) ;
CENTER

Uwe,
I tried and not run
I sent you a snapshot

Silvio,

I tested with ALL possible folder-page-backgrounds
I couldn't find any problem.
Maybe my Testtool can help. I will give You a download-link
