Turn off the KeyPressMask bit for the Canvas Window.
XWindowAttributes attrs;
XSetWindowAttributes set_attrs;
[...]
fl_show_form(fd_try->try,FL_PLACE_CENTERFREE,FL_FULLBORDER,"try");
XGetWindowAttributes( fl_get_display(),
FL_ObjWin( fd_try->canvas ),
&attrs );
set_attrs.event_mask = ~KeyPressMask & attrs.your_event_mask;
XChangeWindowAttributes( fl_get_display(),
FL_ObjWin( fd_try->canvas ),
CWEventMask,
&set_attrs );
By default, the KeyPressMask, ExposureMask, and StructureNotifyMask
bits are set in the Canvas object event mask.
