Virtual Method

GtkCellAreaget_preferred_height_for_width

since: 3.0

Declaration [src] 

void
get_preferred_height_for_width (
  GtkCellArea* area,
  GtkCellAreaContext* context,
  GtkWidget* widget,
  gint width,
  gint* minimum_height,
  gint* natural_height
)

Description [src]

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

area stores some geometrical information in context along the way while calling gtk_cell_area_get_preferred_width(). It’s important to perform a series of gtk_cell_area_get_preferred_width() requests with context first and then call gtk_cell_area_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 gtk_cell_area_get_preferred_width() again and then the full width of the requested rows checked again with gtk_cell_area_context_get_preferred_width().
