That loop should probably be:
while (run_make->value() == 1) {
Fl::wait(0.5);
}
[Your call to Fl::flush() just flushes the graphics,
it doesn't yield cpu to FLTK for processing events.]
*Or*, possibly better, just delete all of this:
----
sleep(1);
while (run_make->value() == 1) {
sleep(1); frame->redraw(); Fl::flush();}
o->activate(); frame->cursor(FL_CURSOR_DEFAULT);
----
..so that the function just returns after the
Fl::add_fd() so that Fl::run() will take over, keeping
the interface alive, and HandleFD() will automatically
be called until all the data is read.
Then you can return the cursor to normal and reactivate
the widget by adding these 2 lines just after the pclose():
----
if ( fgets(results, 1023, G_fp) == NULL ) {
run_make->value(0);
Fl::remove_fd(fileno(G_fp));
pclose(G_fp);
frame->cursor(FL_CURSOR_DEFAULT); // ADD THIS LINE
run_make->activate(); // ADD THIS LINE
return;
}
----
I think that approach is better, at least in this case,
because there's no reason for the loop; the loop pretty
much simulates what Fl::run() is already doing for you
anyway.
HTH.
