Message 1 in thread
Is it possible to change the spacing of the letters drawn with
QPainter::drawText?

it's a bit hairy.
QFontMetrics is going to contain most of what you need. looks
like maybe making your own QFont/QFontMetrics subclasses would let you
override QFontMetrics::leading() (inter-line-spacing), e.g., if that's
what you want.
inter-letter-spacing ("kerning") is rather more work. fonts
already have a notion of how close to an "i" another given letter is
allowed to be, e.g. to override that, it seems you'd basically have to
handle it on a character-by-character basis -- look at
QFontMetrics::width() for how kerning is basically a composite of base
character width and its left- and right-bearings.
now, whether or not you can subclass those things and actually
paint glyphs at a reasonable speed, i'm not sure. but QFontMetrics is the
place to start, at least.
good luck,
