CellArea.getPreferredHeight

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

Retrieves a cell area’s initial minimum and natural height.

area will store some geometrical information in context along the way; when requesting sizes over an arbitrary number of rows, it’s not important to check the minimum_height and natural_height of this call but rather to consult [gtk.cell_area_context.CellAreaContext.getPreferredHeight] after a series of requests.

Parameters

`context`	the #GtkCellAreaContext to perform this request with
`widget`	the #GtkWidget where area will be rendering
`minimumHeight`	location to store the minimum height, or null
`naturalHeight`	location to store the natural height, or null
