From ac18bf760907d148490594a1a38dfa311978fcef Mon Sep 17 00:00:00 2001
From: Matthias Melcher So that we can keep track of changes to the file, we also want to add
a "modify" callback: Finally, we want to use a mono-spaced font like FL_COURIER:
-w->editor = new Fl_Text_Editor(0, 30, 640, 370);
-w->editor->buffer(textbuf);
+w->editor = new Fl_Text_Editor(0, 30, 640, 370);
+w->editor->buffer(textbuf);
-textbuf->add_modify_callback(changed_cb, w);
-textbuf->call_modify_callbacks();
+textbuf->add_modify_callback(changed_cb, w);
+textbuf->call_modify_callbacks();
-w->editor->textfont(FL_COURIER);
+w->editor->textfont(FL_COURIER);
