: I then compiled fltk-nanox-pre6 and received no errors. However when I
: run the fltk demos I don't seem to get any input from my mouse or
: keyboard. The demos draw to the frame buffer but the mouse pointer just
: sits in the center of the screen not responding to mouse movement or
: button presses and no key presses from the keyboard seem to have any
: effect. All I can do is kill the app from another shell. No errors are
: reported to stderr.
The mouse problem is very strange, but here is a patch
that seems to work. I think this is related to the pollability
of the particular mouse driver, it has always worked on my
system:
The following is a dirty fix to the problem:
Originally, in Fl_x.cxx, Row 209:
--------------------------------
// GrCheckNextEvent(&ev);
// if(ev.type!=0)
if(GrPeekEvent(&ev))
{
do_queued_events();
return time;
}
Dirty fix:
---------
GrCheckNextEvent(&ev);
if(ev.type!=GR_EVENT_TYPE_NONE)
// if(GrPeekEvent(&ev))
{
fl_handle(ev);
do_queued_events();
return time;
}
In regards to the keyboard problem, make sure that you
have TTYKBD=Y in the config file. If the kbd still doesn't
work after the patch, please send complete system version
details.
Regards,
Greg
