Doing a redraw() after loading the data should work..
definitely don't use hide/show to force the redraw.
Just be sure to tell the *Window* to redraw.
eg. in your callback:
static void read_callback(Fl_Widget *w, void*) {
[[ ..load your data here, update charts.. ]]
w->window()->redraw(); // schedule the parent window to redraw itself
}
Or, if you have a direct pointer to the parent window
of the widget that needs updating, tell that to redraw().
When your callback returns, FLTK will handle doing the
actual redraw.
