DESCRIPTION

17       tickit_pen_has_attr()   tests  whether  a  pen  instance  has  a  given
18       attribute  defined  on  it.  It  returns  true  if  the   corresponding
19       tickit_pen_set_*_attr() function has been called since construction, or
20       the last time it was cleared. This is true even if  the  attribute  has
21       been set to its default value.
22
23       tickit_pen_nondefault_attr()  tests  whether a pen instance has a given
24       attribute defined with a non-default value.  It  returns  true  if  the
25       attribute  is  set  to a value that is not the default, or false if the
26       attribute is absent, or set to the default  value  for  that  attribute
27       type.

RETURN VALUE

30       tickit_pen_has_attr()  and  tickit_pen_nondefault_attr() return a bool‐
31       ean.
