get_preferred_width_for_height

Description:

public virtual void get_preferred_width_for_height (CellAreaContext context, Widget widget, int height, out int minimum_width, out int natural_width)

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

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

Parameters:

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