From a931e84e8b17f6529959ef0559eb012e08d3f2c1 Mon Sep 17 00:00:00 2001 From: Georg Baum Date: Thu, 8 Sep 2016 22:01:22 +0200 Subject: [PATCH] Prepare for mutlicolumn lines The \multicolumn command allows to set vertical lines for individual rows. These are not yet displayed, but if they are supported one day, the code in a27ff13663 needs to be adjusted. This change hints at the adjustment. --- src/mathed/InsetMathGrid.cpp | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/src/mathed/InsetMathGrid.cpp b/src/mathed/InsetMathGrid.cpp index 4e9de1de10..3d60683a9b 100644 --- a/src/mathed/InsetMathGrid.cpp +++ b/src/mathed/InsetMathGrid.cpp @@ -636,10 +636,13 @@ void InsetMathGrid::drawWithMargin(PainterInfo & pi, int x, int y, - i * vlinesep() - vlinesep()/2 - colsep()/2; int top_offset; - if (r > 0) + // prevRowHasLine needs to be changed if multicolumn lines are supported + bool const prevRowHasLine(r > 0); + if (prevRowHasLine) + // start from offset of previous row to create a continous line top_offset = rowinfo_[r - 1].offset_ + rowinfo_[r - 1].descent_; else - top_offset = rowinfo_[0].offset_- rowinfo_[0].ascent_; + top_offset = rowinfo_[r].offset_- rowinfo_[r].ascent_; pi.pain.line(xx, y + top_offset, xx, y + rowinfo_[r].offset_ + rowinfo_[r].descent_, Color_foreground);
