Hi.

This code works, but need be cleared and optimized. Sorry but I start it and don't have time to finish.

Use it in ON INIT clause of an dialog like:

ACTIVATE DIALOG...ON INIT INITSHADOW( oDlg:hWnd ) )

Code: Select all  Expand view
#pragma BEGINDUMP

#include "windows.h"
#include "hbapi.h"

#define S_SHADE 5

HB_FUNC( INITSHADOW )
{
        RECT rc;
        HWND hWnd = ( HWND ) hb_parnl( 1 );
        HDC dc = GetDC( NULL );

        HDC tdc = CreateCompatibleDC( dc );
        HBITMAP map1 = CreateCompatibleBitmap( dc,1600,1200);
        HGDIOBJ hOldBmp;
        int w,e;
        float f,g;
         GetWindowRect( hWnd, &rc );

        hOldBmp = SelectObject( tdc, map1 );
        BitBlt( tdc, rc.left,rc.top,rc.right+S_SHADE, rc.bottom+S_SHADE,dc,rc.left,rc.top,SRCCOPY);

        for( w=rc.right;w<=rc.right+S_SHADE;w++)
        {
            f=((float)w-rc.right)/S_SHADE;
            for(e=rc.top+S_SHADE;e< rc.bottom;e++)
            {
                SetPixel(tdc, w,e,RGB(
                    GetRValue(GetPixel(tdc,w,e))/(2-f),
                    GetGValue(GetPixel(tdc,w,e))/(2-f),
                    GetBValue(GetPixel(tdc,w,e))/(2-f)));
            }
        }

        for(e=rc.bottom;e<=rc.bottom+S_SHADE;e++)
        {
            f=((float)e-rc.bottom)/S_SHADE;
            for(w=rc.left+S_SHADE;w<=rc.right+1;w++)
            {
                SetPixel(tdc,w,e,RGB(
                GetRValue(GetPixel(tdc,w,e))/(2-f),
                GetGValue(GetPixel(tdc,w,e))/(2-f),
                GetBValue(GetPixel(tdc,w,e))/(2-f)));
            }
        }

        for(e=rc.bottom;e<=rc.bottom+S_SHADE-2;e++)
        {
            f=((float)e-rc.bottom)/S_SHADE;
            for(w=rc.right+2;w<=rc.right+S_SHADE-2;w++)
            {
                g=((float)w-rc.right+2)/(S_SHADE);
                SetPixel(tdc,w,e,RGB(
                    GetRValue(GetPixel(tdc,w,e))/(2-(f+g)/2),
                    GetGValue(GetPixel(tdc,w,e))/(2-(f+g)/2),
                    GetBValue(GetPixel(tdc,w,e))/(2-(f+g)/2)));
            }
        }

        BitBlt(dc, rc.left,rc.top,rc.right+S_SHADE,rc.bottom+S_SHADE,tdc,rc.left,rc.top,SRCCOPY);

        SelectObject( tdc, hOldBmp );

        hb_retnl( ( LONG ) map1 );
}

#pragma ENDDUMP

Ante todo gracias, pero lo que necesito no solo es poner sombra a un dialogo sino, yo tengo una imagen con ESQUINAS redondeadas y con sombra y utilizarla de fondo del dialogo.

¿Como lo podemos hacer?

Juan,

Revisa este ejemplo:
Code: Select all  Expand view

#include "FiveWin.ch"

function Main()

   local oWnd
   
   DEFINE WINDOW oWnd COLOR 0, CLR_WHITE
     
   ACTIVATE WINDOW oWnd MAXIMIZED ;
      ON INIT Test( oWnd )

return nil

function Test( oWnd )

   local oDlg, oBrush
   local oBmp, hDC, hBmpBack
   local nTop, nLeft, nBottom, nRight, nWidth, nHeight  
   local cTest := Space( 10 )

   DEFINE BITMAP oBmp FILENAME "dialog4.bmp"

   nWidth   = nBmpWidth( oBmp:hBitmap )
   nHeight  = nBmpHeight( oBmp:hBitmap )
   nLeft    = ( GetSysMetrics( 0 ) / 2 ) - nWidth / 2
   nTop     = ( GetSysMetrics( 1 ) / 2 ) - nHeight / 2
   nRight   = nLeft + nWidth - 1
   nBottom  = nTop + nHeight - 1

   hBmpBack = FWSaveScreen( oWnd:hWnd, nTop, nLeft, nBottom, nRight )

   DEFINE BRUSH oBrush COLOR CLR_RED // STYLE NULL             // Transparent painting !

   DEFINE DIALOG oDlg ;
      FROM 2, 2 TO 23, 45 ;
      STYLE WS_POPUP ;
      BRUSH oBrush ;

   @ 3.5, 7.5 GET cTest

   ACTIVATE DIALOG oDlg CENTERED ;
      ON PAINT ( ABPaint( hDC := GetWindowDC( oWnd:hWnd ), nLeft, nTop, oBmp:hBitmap, 150 ), ReleaseDC( oWnd:hWnd, hDC ) ) ;
      ON INIT SetTransparent( oDlg ) ;
      VALID ( FWRestScreen( oWnd:hWnd, hBmpBack, nTop, nLeft, nBottom, nRight ), DeleteObject( hBmpBack ), .T. ) ;
      ON CLICK oDlg:End()

   oBmp:End()
     
return nil

//----------------------------------------------------------------------------//

#define LWA_COLORKEY  1
#define GWL_EXSTYLE   -20
#define WS_EX_LAYERED 524288


STATIC FUNCTION SETTRANSPARENT( oDlg )

   SETWINDOWLONG( oDlg:hWnd, GWL_EXSTYLE, NOR( GETWINDOWLONG( oDlg:hWnd, GWL_EXSTYLE ), WS_EX_LAYERED ) )

   SETLAYEREDWINDOWATTRIBUTES( oDlg:hWnd, CLR_RED,, LWA_COLORKEY )

RETURN NIL

Juan,

En el PRG que te dice Bayron, revisa la función MsgSplash() que no precisa de una ventana posterior.

Antonio,

Si no estoy equivocado, de esta manera, podriamos presentar aplicaciones que respetan el area del modelo rectangular, pero que se presente en pantalla de manera irregular, cierto???

Ejemplo, de manera circular, triangular, etc...
