Transparents radios

[Marcelo Via Giglio]

Hello,

I trying to display radios inside a painted area ( painted with GradientFill or RoundRect ) on dialog, the dialog is defined like TRANSPARENT ( DEFINE DIALOG..... TRANSPARENT ), the say are displayed correctly, but the radios no, I am using
AEval( oRadio:aItems, { | oRm | oRm:lTransparent := .T. } ) to define transparent in radio but I can't obtain the right result

some sugestion?

Marcelo,

please have a look at the Dialog-background-function.

Code: Select all  Expand view

FUNCTION SHOW_MSG()
Local nValue := 3, oRad

DEFINE DIALOG oPopup FROM nTop, nLeft TO nTop + 280, nLeft + 300 OF oDlg PIXEL FONT oSysFont1 ;
TITLE cHead TRANSPARENT ;
STYLE nOr(WS_POPUP, WS_BORDER, WS_THICKFRAME, WS_CAPTION )

@ 100, 5 RADIO oRad VAR nValue  PIXEL ;
ITEMS "&One", "&Two", "T&hree" _3D SIZE 40, 12 ;
HELPID 100, 101, 102 ;
ON CHANGE MsgBeep()

DLG_BRUSH( oPopup, 1, .T., 16770250, 14089979, 0.2 )

ACTIVATE DIALOG oPopup

RETURN( NIL )

//--------- DIALOG Background ------------------------

FUNCTION DLG_BRUSH(oControl, nStyle, lDirect, nVColor, nBColor, nMove, cBrush, cImage)
LOCAL oBrush, oTmp
LOCAL aGrad := { { nMove, nVColor, nBColor }, { nMove, nBColor, nVColor } }

IF nStyle = 1
    hDC = CreateCompatibleDC( oControl:GetDC() )
    hBmp = CreateCompatibleBitMap( oControl:hDC, oControl:nWidth, oControl:nHeight )
    hBmpOld = SelectObject( hDC, hBmp )
    GradientFill( hDC, 0, 0, oControl:nHeight, oControl:nWidth, aGrad, lDirect )
    DeleteObject( oControl:oBrush:hBrush )
    oBrush := TBrush():New( ,,,, hBmp )
    oBrush:Cargo  := aGrad
    SelectObject( hDC, hBmpOld )
    oControl:ReleaseDC()
    oControl:SetBrush( oBrush )
    RELEASE BRUSH oBrush
ENDIF
IF nStyle = 2
    IF File( cImage )
        DEFINE IMAGE oTmp FILE cImage
            oBrush := TBrush():new( ,,,, ResizeBmp( oTmp:hBitmap, oControl:nWidth, oControl:nHeight, .T. ) )
        oControl:SetBrush( oBrush )
        oBrush:End()
    ELSE
        MsgAlert( "Cannot load : " + CRLF + ;
                 cImage, "Error" )
    ENDIF
ENDIF

RETURN( NIL )

Uwe,

thanks for response, ok, I can see the transparent radio, but how can I do it, BUT please take in mind that I don't use a gradient or other dialog background, only some dialog area are painted and inside it, I want to put the radios, the says work perfectly.

regards

Marcelo

P.D. sorry I didn't see the code, I will try thanks

[Marcelo Via Giglio]

Uwe,

your sample is using background dialog brush, it is possible to do without brush? only paint some dialog area

regards

Marcelo

// Area
GradientFill( hDC, 50, 0, 130, 100, aGrad, lDirect )

// complete
// GradientFill( hDC, 0, 0, oControl:nHeight, oControl:nWidth, aGrad, lDirect )

Best Regards
Uwe

Thanks again Uwe,

but I have a problems with brush, what I am using is a RGROUP class this means that is working like a control, and we can use many of it in the same dialog, do you know if are there others possibilities for solve this issue

regards and thanks for your time

Marcelo
