Fl_Text_Buffer / Fl_Text_Display removal of lines. How?

How do I remove a line or a set of lines from the beginning of a Fl_Text_Buffer / Fl_Text_Display so as to keep the display under control

Hi Gonzalo,

I'm not sure I understood the question... Are you wanting to trim lines off the start of your text buffer, with the intention of stopping it growing too large?

So, you can use  Fl_Text_Buffer::remove (start, end) to cut stuff out, set start = 0 and use  line_start (pos)  to find the start of some line that we can use for end.

Should work at any rate...

Or I'm answering the wrong question?

Yes, that was it.   You nailed it with remove(), line_start(), etc.
