The basic function to do this is fl_redraw_form(). It will cause the
entire form to be redrawn, in order.
If the background Pixmap is large or the form is complicated, this may
cause an unpleasant amount of flicker. This can be alleviated by
making the form double buffered and bracketing the redraw and update
with fl_freeze_form()/fl_unfreeze_form() calls:
FD_try *fd_try = ( FD_try *) ob->form->fdui;
[...]
fl_set_form_dblbuffer( ob->form, 1 );
fl_freeze_form( ob->form );
fl_free_pixmap_pixmap( fd_try->background_pixmap );
fl_set_pixmap_data( fd_try->background_pixmap, new );
fl_redraw_form( ob->form );
fl_unfreeze_form( ob->form );
fl_set_form_dblbuffer( ob->form, 0 );
Bracketing the whole mess with fl_set_form_dblbuffer() allows the rest
of the form processing to be handled in a single buffer mode, which
generally produces better apparent performance. Double buffering
introduces a bit of a delay in updating forms, particularly relatively
complicated ones.
