This is because MetricsInfo::MetricsInfo() is not implemented. >The problem is that the MetricsInfo is not available.

You can store all the asc en desc of the cells in CellData. This can be done in InsetTabular::metrics. This is now also done for the rows. (cell_info[row][col].asc = ...). 2. Or, maybe you can call something like this: text_ = cellInset(cell)->text(); TextMetrics & tm = pi.base.bv->textMetrics(&text_); >p.s. I still don't understand how exactly dim.asc is calculated. Where >in the code is this done? Well. Have a look in the code then :S ? InsetTabular::metrics() calls InsetText::metrics() which calls TextMetrics::metrics() which calls ParagraphMetrics::ascent()... Vincent
