求改Delphi实现代码：
以下是显示在Delphi窗体内的代码：
貌似不支持组合键显示
[Delphi] 纯文本查看 复制代码 unit Unit2;
interface
uses
Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants,
System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs;
type
TForm2 = class(TForm)
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
procedure MyMsg(var msg: TWMKeyDown); message WM_KEYDOWN;
public
{ Public declarations }
end;
var
Form2: TForm2;
implementation
{$R *.dfm}
procedure TForm2.FormCreate(Sender: TObject);
begin
Canvas.Font.Size := 24;
Canvas.Font.Style := [fsBold];
Canvas.Font.Color := clRed;
Canvas.Brush.Color := clWhite;
end;
procedure TForm2.MyMsg(var msg: TWMKeyDown);
var
buf: array[0..255] of Char;
rect: TRect;
str: string;
begin
{获取}
GetKeyNameText(msg.KeyData, buf, Length(buf));
{画出来}
str := buf;
rect := ClientRect;
Canvas.FillRect(rect);
Canvas.TextRect(rect, str, [tfSingleLine, tfCenter, tfVerticalCenter]);
inherited;
end;
end.
