Hi,

I'm new to dephi. I have search the net for the component but i couldn't install it.
Do you know where I could get a simple component just to change my existing radio button on the form to be transparent? I want the background colour of the text for the radio button and group box to be transparent.

I notice that if you are running windows XP style it automatically do it for you. do you know why?

Thanks

Check out the free LMD Component set (has a TRadioGroup w/ transparent display)

Thanks Shane,

I know that works but I need to convert the normal group box and radio box delphi provide to transparent colour?

Do you know the code or a component to convert that?

Thanks again

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Try this.

First try it with just the CreateParams overriden, then tru overridding the Paint method.

Shane


  TTransGroup = class(TGroupBox)
  protected
    procedure CreateParams(var Params: TCreateParams); override;
    procedure Paint; override;
    end;


procedure TTransGroup.CreateParams(var Params: TCreateParams);
begin
  inherited CreateParams(Params);
  if not (csDesigning in ComponentState)
    then Params.ExStyle:=Params.ExStyle or WS_EX_TRANSPARENT;
  end;

procedure TTransGroup.Paint;
var
  XBitMap: TBitMap;
  XOldDC: HDC;
  XRect: TRect;
begin
{This panel will be transparent only in Run Time}
  if (csDesigning in ComponentState)
    then inherited Paint
  else begin
    XRect:=ClientRect;
    XOldDC:=Canvas.Handle;
    XBitMap:=TBitMap.Create;
    try
      XBitMap.Height:=Height; XBitMap.Width:=Width;
      Canvas.Handle:=XBitMap.Canvas.Handle;
      inherited Paint;
      RedrawWindow(Parent.Handle, @XRect, 0,
                   RDW_ERASE or RDW_INVALIDATE or
                   RDW_NOCHILDREN or RDW_UPDATENOW);
    finally
      Canvas.Handle:=XOldDC;
      Canvas.BrushCopy(XRect, XBitMap, XRect, Color);
      XBitMap.Free;
      end;
    end;
  end;
