Gtk.CellArea::get_preferred_width_for_height

function vfunc_get_preferred_width_for_height(context:Gtk.CellAreaContext, widget:Gtk.Widget, height:Number):void {
}

Retrieves a cell area's minimum and natural width if it would be given the specified height.

area stores some geometrical information in context along the way while calling Gtk.CellArea.prototype.get_preferred_height. It's important to perform a series of Gtk.CellArea.prototype.get_preferred_height requests with context first and then call Gtk.CellArea.prototype.get_preferred_width_for_height on each cell area individually to get the height for width of each fully requested row.

If at some point, the height of a single row changes, it should be requested with Gtk.CellArea.prototype.get_preferred_height again and then the full height of the requested rows checked again with Gtk.get_preferred_height.
