The CAPI interface supports the use of other fonts for text in title panes and other CAPI objects, such as buttons, through the use of the
:font
keyword. If the CAPI cannot find the specified font it reverts to the default font. The
:font
keyword applies to data following the
:text
keyword. The value is a graphics ports
gp:font-description
object specifying various attributes of the font.
On systems running X Windows, the
xlsfonts
command can be used to list which fonts are available. The X logical font descriptor can be explicitly passed as a string to the
:font
initarg, which will convert them.
Here is an example of a
title-pane
with an explicit font:
(contain
(make-instance 'title-pane
:text "A title pane"
:font (gp:make-font-description
:family "Times"
:size 12
:weight :medium
:slant :roman)))
Here is an example of using
:font
to produce a title pane with larger lettering. Note that the CAPI automatically resized the pane to fit around the text.
(contain
(make-instance 'title-pane
:text "A large piece of text"
:font (gp:make-font-description
:family "Times"
:size 34
:weight :medium
:slant :roman)))
