How can I change the default font size in tk?

Ruby
1

root = TkRoot.new do
font {Tahoma 10 normal}
end

can’t work.

2

I found TkOptionDB.add( “*font”, “{Lucida Sans Unicode} 10” ) works£¬but
Tk::Tile didn’t change.

I know how:
TkFont.configure(‘TkDefaultFont’, ‘family’ => ‘Lucida Sans Unicode’,
‘size’
=> ‘10’)
