CellArea.getPreferredHeightForWidth

void getPreferredHeightForWidth(gtk.cell_area_context.CellAreaContext context,  gtk.widget.Widget widget,  int  width,  out  int  minimumHeight,  out  int  naturalHeight)

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

area stores some geometrical information in context along the way while calling [gtk.cell_area.CellArea.getPreferredWidth]. It’s important to perform a series of [gtk.cell_area.CellArea.getPreferredWidth] requests with context first and then call [gtk.cell_area.CellArea.getPreferredHeightForWidth] on each cell area individually to get the height for width of each fully requested row.

If at some point, the width of a single row changes, it should be requested with [gtk.cell_area.CellArea.getPreferredWidth] again and then the full width of the requested rows checked again with [gtk.cell_area_context.CellAreaContext.getPreferredWidth].

Parameters

`context`	the #GtkCellAreaContext which has already been requested for widths.
`widget`	the #GtkWidget where area will be rendering
`width`	the width for which to check the height of this area
`minimumHeight`	location to store the minimum height, or null
`naturalHeight`	location to store the natural height, or null
