get_preferred_height_for_width

Description:

public virtual void get_preferred_height_for_width (CellAreaContext context, Widget widget, int width, out int minimum_height, out int natural_height)

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

this stores some geometrical information in context along the way while calling get_preferred_width. It’s important to perform a series of get_preferred_width requests with context first and then call get_preferred_height_for_width 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 get_preferred_width again and then the full width of the requested rows checked again with get_preferred_width.

Parameters:

this	a `GtkCellArea`
context	the `GtkCellArea`Context which has already been requested for widths.
widget	the `GtkWidget` where this will be rendering
width	the width for which to check the height of this area
minimum_height	location to store the minimum height
natural_height	location to store the natural height
