Check the pointer (or 'this') for NULL.
So if you're doing:
fl_throw_focus(otherwidget);
..then check otherwidget for NULL.
Or, if using 'this', check 'this' for NULL.
Make sure all pointers are initialized to NULL
so that you can tell an uninitialized pointer
from a wild pointer address. (Sometimes wild addresses
in uninitialized pointers are hard to tell from good addresses)
If you're getting a crash, and have FLTK in debug mode,
check the arguments passed to the subroutines in the calling
hierarchy for NULLs. 'this' should almost never be NULL.
