Change a form's caption font and alignment (2) (Views: 101)


Problem/Question/Abstract:

Does anyone know how to write text with the TEXTOUT command in the title bar of a form in D5?

Answer:

You have to handle the WM_NCPAINT message.

{ ... }
type
  TForm1 = class(TForm)
  private
    procedure WMNCPaint(var Msg: TWMNCPaint); message WM_NCPAINT;
  public
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.WMNCPaint(var Msg: TWMNCPaint);
var
  ACanvas: TCanvas;
begin
  inherited;
  ACanvas := TCanvas.Create;
  try
    ACanvas.Handle := GetWindowDC(Form1.Handle);
    with ACanvas do
    begin
      Brush.Color := clActiveCaption;
      Font.Name := 'Tahoma';
      Font.Size := 8;
      Font.Color := clred;
      Font.Style := [fsItalic, fsBold];
      TextOut(GetSystemMetrics(SM_CYMENU) + GetSystemMetrics(SM_CXBORDER),
        Round((GetSystemMetrics(SM_CYCAPTION) - Abs(Font.Height)) / 2) + 1,
          ' Some Text');
    end;
  finally
    ReleaseDC(Form1.Handle, ACanvas.Handle);
    ACanvas.Free;
  end;
end;
