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 CellArea |
| context |
the CellAreaContext which has already been requested for widths. |
| widget |
the Widget 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, or null |
| natural_width |
location to store the natural width, or null |
