Storm" Date: Wed, 21 Jul 2004 21:09:43 +0000 Subject: [PATCH] (display_line): Increment nrows_scale_factor and set fonts_changed_p if past last allocated row. (append_glyph, append_composite_glyph, produce_image_glyph) (append_stretch_glyph): Increment ncols_scale_factor and set fonts_changed_p if current area is full. --- src/xdisp.c | 30 +++++++++++++++++++++++++++--- 1 file changed, 27 insertions(+), 3 deletions(-) diff --git a/src/xdisp.c b/src/xdisp.c index d273de74847..4083ce7a438 100644 --- a/src/xdisp.c +++ b/src/xdisp.c @@ -14462,9 +14462,13 @@ display_line (it) /* We always start displaying at hpos zero even if hscrolled. */ xassert (it->hpos == 0 && it->current_x == 0); - /* We must not display in a row that's not a text row. */ - xassert (MATRIX_ROW_VPOS (row, it->w->desired_matrix) - < it->w->desired_matrix->nrows); + if (MATRIX_ROW_VPOS (row, it->w->desired_matrix) + >= it->w->desired_matrix->nrows) + { + it->w->nrows_scale_factor++; + fonts_changed_p = 1; + return 0; + } /* Is IT->w showing the region? */ it->w->region_showing = it->region_beg_charpos > 0 ?
