Hi,

Is it possible to embed a font for a GUI application in Lazarus in a platform independent way? I've been looking on the internet and I only found windows specific solutions so far.

Regards, Darius

You already know the windows way, so I'll omit it.

With qt you can use QFontDatabase_addApplicationFont, e.g.

uses qt4;
...
procedure TForm1.FormCreate(Sender: TObject);
var ws:WideString;
begin
   ws:='/file/with/the/font.ttf';
   QFontDatabase_addApplicationFont(@ws)
end;

There's also a addApplicationFontFromData if you want to load the font from a resource.

With GTK you can use fontconfig, e.g.

uses fontconfig;
....
function FcConfigAppFontAddFile(config:pointer;
fname:Pchar):FcBool;stdcall;external 'libfontconfig.so';
....
procedure TForm1.FormCreate(Sender: TObject);
var
   res: FcBool;
begin
   res:=FcConfigAppFontAddFile(nil,'/file/with/the/font.ttf');
end;

There isn't a function to load the font from data, so if you want to use resources I guess you should save it to a temporary file and load the font from it.

What I couldn't find is a way to know if the application is using qt or gtk (or win): LCLWidgetType is an ide macro, not a define.

Bye

Thanks Luca!

Does anyone how to make it natively work on the Mac?
