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
