Rounded and titled "TPanel" in Delphi 7 - delphi

Question

I would have a TPanel in my application but with another look.
For it I want a colored title bar and the up corner rounded just like in some user interfaces like it
Do you know any component or library for it ? (Prefered Open source but not only).
I tried TJVCaptionPanel it's OK but needs rounded up corner.

Like this?
unit CustomCaptionPanel;
interface
uses
Windows, SysUtils, Classes, Controls, Graphics;
type
TCustomCaptionPanel = class(TCustomControl)
private const
DEFAULT_BORDER_COLOR = $0033CCFF;
DEFAULT_CLIENT_COLOR = clWindow;
DEFAULT_BORDER_RADIUS = 16;
private
{ Private declarations }
FBorderColor: TColor;
FClientColor: TColor;
FBorderRadius: integer;
FCaption: TCaption;
FAlignment: TAlignment;
procedure SetBorderColor(BorderColor: TColor);
procedure SetClientColor(ClientColor: TColor);
procedure SetBorderRadius(BorderRadius: integer);
procedure SetCaption(const Caption: TCaption);
procedure SetAlignment(Alignment: TAlignment);
protected
{ Protected declarations }
procedure Paint; override;

Answer 2

If you wanna round the corner of anything you want, try this:
procedure RoundCornerOf(Control: TWinControl) ;
var
R: TRect;
Rgn: HRGN;
begin
with Control do
begin
R := ClientRect;
rgn := CreateRoundRectRgn(R.Left, R.Top, R.Right, R.Bottom, 20, 20) ;
Perform(EM_GETRECT, 0, lParam(#r)) ;
InflateRect(r, - 4, - 4) ;
Perform(EM_SETRECTNP, 0, lParam(#r)) ;
SetWindowRgn(Handle, rgn, True) ;
Invalidate;
end;
end;
