Right. The font face is depending on the platform you're on. This is set at
the Font theme which is provided by the framework. As long as you do not
change this behaviour by using your own font theme these settings will be
applied.

The best way would be to implement an own Font theme. Take a look at your
application class structure. There should be a folder "theme" by default and
also a provided (empty) Font theme.
There you can implement your own fonts and then you can use them throughout
your application by using the name you chosen.
--snip--
// part of the framework font theme
qx.Theme.define("qx.theme.modern.Font",
{
fonts :
{
"default" :
{
size : (qx.bom.client.System.WINVISTA || qx.bom.client.System.WIN7) ? 12
: 11,
lineHeight : 1.4,
family : qx.bom.client.Platform.MAC ? [ "Lucida Grande" ] :
(qx.bom.client.System.WINVISTA || qx.bom.client.System.WIN7) ?
[ "Segoe UI", "Candara" ] :
[ "Tahoma", "Liberation Sans", "Arial", "sans-serif" ]
}
}
}
// in your application
yourLabel.setFont("default");

Take a look at the documentation at
http://qooxdoo.org/documentation/1.0/ui_theming#font_theme
to get to know more about font themes and theming in general.
cheers,
Alex
