In that example, the rows vary in height based on the data that is rendered
in each row. In particular, the image renderer is specified for column one,
with this code:
// Tell the row renderer to use an image renderer for column 1 var r = new
qx.ui.progressive.renderer.table.cell.Image(); rowRenderer.addRenderer(1, r);
It sounds like you'd like varying row heights based on something else. If
you look at how the cell renderers are implemented, you'll see that each
cell in a row is passed the height, determined so far by previous cells in
the row. Any cell renderer can set the height to something larger. See the
documentation in the shaded area here:
http://demo.qooxdoo.org/current/apiviewer/#qx.ui.progressive.renderer.table.cell.Abstract
To accomplish your goal, you need simply create a cell renderer that selects
the minimum row height based on something in the data model.
You might also look at qx.ui.virtual.* to see if something there meets your
needs. Although I wrote "progressive" and expect it to still be an
appropriate tool for some applications, many of its benefits are now being
provided by the much more modern "virtual" infrastructure with data binding.
(A full replacement for a virtual table, however, has not yet been
implemented.)
