TICKIT_WINDOW_GET_PEN(3) Library Functions Manual TICKIT_WINDOW_GET_PEN(3) NAME tickit_window_get_pen, tickit_window_set_pen - manipulate the window's rendering pen SYNOPSIS #include <tickit.h> TickitPen *tickit_window_get_pen(const TickitWindow *win); void tickit_window_set_pen(TickitWindow *win, TickitPen *pen); Link with -ltickit. DESCRIPTION tickit_window_get_pen() returns a pointer to the given window's pen in- stance. This pen instance is directly stored by the window. The appli- cation is permitted to modify this pen instance, though any modifica- tions will not be observed until the window is next exposed for render- ing. tickit_window_set_pen() stores a new pointer for a pen instance into the given window. The window retains a reference to that pen and incre- ments the reference count on it. Any previous pen is unreferenced first. Because the window stores what may be one of many references to the pen instance, applications that do modify the pen should be careful that such modifications do not adversely affect other users of the same pen. RETURN VALUE tickit_window_get_pen() returns a pointer to a pen instance. tickit_window_set_pen() returns no value.
