Re: [paragui-dev] PG_Font Repost - plaintext version

[Alexander Pipelka]

Maybe you didn't notice it but PG_Font has a non public constructor.
That means you cannot create PG_Font objects by yourself.

Why do you want to do that ?

Just use 'PG_Widget::SetFontName("myfont.ttf");'.
That much easier i think.

If you take a look at the simple.zip file.
It's structured like this:

simple.theme
simple/font.ttf
simple/*.png

If you would like to access simple.theme you would pass "simple.theme"
to PG_FileArchive. If you want to access "font.ttf" in there you need
"simple/font.ttf" !!

Got it ?
