change bitmaps from radio button

[Silvio.Falconi]

I need to change a small bitmaps from radio button ..How I can make ...is there a test sample ?
I use radio control for the first element and the I use radiomenu for the other element

sample :

@ 8, 11 SAY "&Avviso:" SIZE 45, 7 PIXEL OF oFld4:aDialogs[3] COLOR 0, 14215660
@ 6, 51 RADIO aGet[25] VAR nMessaggioComunicazioni Prompt "No" SIZE 30, 10 PIXEL OF oFld4:aDialogs[3] on change refresh_bitmap_avviso(nMessaggioComunicazioni,oBmp[2])
@ 6, 100 RADIOITEM "&Mail" RADIOMENU aGet[25] OF oFld4:aDialogs[3] PIXEL SIZE 30, 10
@ 6, 150 RADIOITEM "&Sms" RADIOMENU aGet[25] OF oFld4:aDialogs[3] PIXEL SIZE 30, 10
@ 6, 190 RADIOITEM "&Telefono" RADIOMENU aGet[25] OF oFld4:aDialogs[3] PIXEL SIZE 30, 10

@ 22, 342 BITMAP oBmp[2] RESOURCE "XPINFO" PIXEL OF oFld4:aDialogs[3] NOBORDER SIZE 32,32 ADJUST
oBmp[2]:ltransparent:=.t.

........

Function refresh_bitmap_avviso(nMessaggioComunicazioni,oBmp[2])
Do case
case nMessaggioComunicazioni = 1
oBmp[2]:cBitmap:="NOavviso"
case nMessaggioComunicazioni = 2
oBmp[2]:cBitmap:="MailAvviso"
case nMessaggioComunicazioni = 3
oBmp[2]:cBitmap:="avvisoSms"
case nMessaggioComunicazioni = 4
oBmp[2]:cBitmap:="AvvisoTel"
endcase
oBmp[2]:refresh()
return nil



why not run ?

Any Idea ?

Silvio,

only a quick test ( I still noticed a missing transparency, loading a bmp-resource )

Another solution, setting the image-position related to the radios.

REDEFINE BITMAP oBmpOpc RESOURCE cBmpOpc ID 4008 OF oDlg

elseif nVar=2

Francisco,

Silvio only wants to load BMP's from a resource like :
DEFINE IMAGE oImg RESOURCE "A_EXIT" // FILENAME c_path1 + "A_EXIT.bmp"
or
oImg := FILoadImg( AllTrim( "A_EXIT.bmp" ), , "A_EXIT" )
The problem : it is impossible, to save a alphablended bmp with Resource-Workshop
I tested with a bmp, changing the transparent-area to black, but PalBmpDraw doesn't
show the bmp transparent.

Original 32 bpp with alpha-channel
reduced to
24 bpp with black background ( transparent area replaced with black )



This bmp can be saved as resource with borland resource-workshop

Maybe somebody can show a working sample from resource using PalBmpDraw ?

Best regards
Uwe

Uwe,

I tried with this :

@ 22, 342 BITMAP oBmp[2] RESOURCE NIL PIXEL OF OFld4:aDialogs[3] NOBORDER SIZE 32,32 ADJUST
oBmp[2]:ltransparent:=.t.
oBmp[2]:bPainted := { |hDC| IIF( nMessaggioComunicazioni = 1, ;
hBmp := LoadBitmap( GetResources(), "NOAVVISO" ), NIL ), ;
IIF( nMessaggioComunicazioni = 2, ;
hBmp := LoadBitmap( GetResources(), "MAILAVVISO" ), NIL ), ;
IIF( nMessaggioComunicazioni = 3, ;
hBmp := LoadBitmap( GetResources(), "SMSAVVISO" ), NIL ), ;
IIF( nMessaggioComunicazioni = 4, ;
hBmp := LoadBitmap( GetResources(), "PHONEAVVISO" ), NIL ), ;
PalBmpDraw( hDC, 0, 0, hBmp, ,oBmp[2]:nWidth, oBmp[2]:nHeight, , .T., 0 ), ;
DeleteObject( hBmp ) }


When I select the Radio item the bitmap not refresh
If I select another folder tab and then return on that folder tab the bitmpa is changed
Where isi the error?

Silvio,

I found a short and easy transparent solution that works from resources.

oRad:nClrText := 255 } )

// define the resource, You want to display at startup !!!

@ 70, 120 BITMAP oBmp1 RESOURCE "IMAGE1" PIXEL OF oFld:aDialogs[1] NOBORDER SIZE 32, 32 ADJUST
oBmp1:ltransparent:=.t.

used Borland resource-workshop
because of NO alpha-channel, a clean borderpainting is needed.
