首先定义：
procedure TStatusForm.FormCreate(Sender: TObject) ;
begin
StatusBar1.Panels[0].Style := psOwnerDraw;
StatusBar1.Panels[1].Style := psOwnerDraw;
end;

自画事件：
procedure TStatusForm.StatusBar1DrawPanel(
StatusBar: TStatusBar;
Panel: TStatusPanel;
const Rect: TRect) ;
begin
with StatusBar.Canvas do
begin
case Panel.Index of
0: //fist panel
begin
Brush.Color := clRed;
Font.Color := clNavy;
Font.Style := [fsBold];
end;
1: //second panel
begin
Brush.Color := clYellow;
Font.Color := clTeal;
Font.Style := [fsItalic];
end;
end;
//Panel background color
FillRect(Rect) ;

//Panel Text
TextRect(Rect,2 + ImageList1.Width + Rect.Left, 2 + Rect.Top,Panel.Text) ;
end;

//draw graphics
ImageList1.Draw(StatusBar1.Canvas, Rect.Left, Rect.Top, Panel.Index) ;
end;
