Would need to see the code for your handle() function(s).
The 0|1 values it returns are probably critical.
Also, which version of FLTK and what operating system?
FWIW, I added a handle() function to the the table-sort.cxx
example program to print the events it received, and if I hold
a key down, it repeatedly gets FL_KEYDOWN. Tested with fltk 1.3.x
current svn on linux.
I basically added this line at the top of the example:
#include <FL/names.h>
..and added this method to its MyTable class:
int handle(int e) {
printf("EVENT %s (%d)\n", fl_eventnames[e],e);
return Fl_Table_Row::handle(e);
}
