Virtual Method

GtkCellAreaget_preferred_width_for_height

since: 3.0

Declaration [src]

void
get_preferred_width_for_height (
  GtkCellArea* area,
  GtkCellAreaContext* context,
  GtkWidget* widget,
  gint height,
  gint* minimum_width,
  gint* natural_width
)

Description [src]

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

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