🚀 go-pugleaf

I use the following:

  (Glyph *)_cursor = new Background(
			(LauoutKit *)->spaces(1, 0.2, <current font>,
						<black color>),
                         <black color>
                      );

 (ScrollBox *)_body _ (LayoutKit *)->vscrollbox();
  _body->ref();
 (Composition *)_paragraph[0] = new LRComposition(
                      	          (LayoutKit *)->vbox(5),
                                   new SimpleCompositor,
				   nil,
			            4*72.0,
                                    fil,
				    fil,
				    GlyphIndex(100)
     				);
  _paragraph[0]->insert(GlyphIndex(0), _cursor);
  _paragraph[0]->insert(GlyphIndex(1), (LayoutKit *)->hglue(0, fil, 0));

  _body->insert(GlyphIndex(0), _paragraph[0]);
  _body->insert(GlyphIndex(1), (LayoutKit *)vglue());

  body(_body);
  _paragraph[0]->repair();


-------

  When the program runs, my window comes up with the cursor as i wanted.
  But when I want to add a new _paragraph[x] to the _body,
  the cursor is not visible.

--
 <add newline>
   <remove _cursor, OK>
   <add _paragraph[1]>
    _paragraph[1] = new LRComposition(<as _paragraph[0])
    _paragraph[1]->insert(.._cursor)
    _paragraph[1]->insert(..hglue)

    _body->insert(GlyphIndex(1), _paragraph[1]);
    body(_body);
    _paragraph[1]->repair();
-----
The idea is to add the new paragraph between the last paragraph, and the vglue.
-----

When I want a new line the cursor disappears  and is placed at the next line, but
it is not visible until I type a character.
If I type two Newlines, both are added to _body, but when I start typing
text(placed in last line), the cursor and characters shows up under the previous
line displayed(e.g. the line has some characters). Since I typed two newlines,
there should be 1 line of space between them.

I may no move the cursor upwards, when it comes to a line which is not shown, the
cursor disappears. If I now type some text and later resize the window, the
hidden line becomes visible.

I have tried to use _glyph->damage_all(), when encountering a newline, but still
can't get it right.

BTW. is this a "good" way to implement a software cursor, should I use other
glyphs instead ?
