TICKIT_PEN_COPY

NAME

tickit_pen_copy, tickit_pen_copy_attr - copy attributes from one pen to another

SYNOPSIS

#include <tickit.h>

void tickit_pen_copy(TickitPen *dst, TickitPen *src,
bool overwrite);
void tickit_pen_copy_attr(TickitPen *dst, TickitPen *src,
TickitPenAttr attr);

Link with -ltickit.

DESCRIPTION

tickit_pen_copy() copies attributes that are defined on src into dst. If an attribute is already defined on dst then it will only be changed if overwrite is true; otherwise the existing value will be left alone. It will invoke the TICKIT_EV_CHANGE event on the dst pen instance if the value of at least one attribute has actually changed.

tickit_pen_copy_attr() copies the value of a single attribute from src into dst, or clears it in dst if it is not present in src. It will invoke the TICKIT_EV_CHANGE event on the dst pen instance.

RETURN VALUE

tickit_pen_copy() and tickit_pen_copy_attr() return no value.
