再学 GDI+[43]: 文本输出 - 获取已安装的字体列表

这比用 Screen.Fonts; 获取麻烦一些.
本例效果图:


代码文件:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Memo1: TMemo;
    procedure FormCreate(Sender: TObject);
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

uses GDIPOBJ, GDIPAPI;

procedure TForm1.FormCreate(Sender: TObject);
var
  fontFamilyArr: array of TGPFontFamily;
  fonts: TGPFontCollection;
  fontCount: Integer;
  str: string;
  i: Integer;
begin
  fonts := TGPInstalledFontCollection.Create;
  fontCount := fonts.GetFamilyCount;

  SetLength(fontFamilyArr, fontCount);
  for i := 0 to fontCount - 1 do fontFamilyArr[i] := TGPFontFamily.Create;

  fonts.GetFamilies(fontCount, fontFamilyArr, fontCount);

  Memo1.Clear;
  for i := 0 to fontCount - 1 do
  begin
    fontFamilyArr[i].GetFamilyName(str);
    Memo1.Lines.Add(str);
  end;

  for i := 0 to fontCount - 1 do fontFamilyArr[i].Free;
  fonts.Free;
end;

end.
