Method
GtkCellAreaget_preferred_width_for_height
Declaration [src]
void
gtk_cell_area_get_preferred_width_for_height (
GtkCellArea* area,
GtkCellAreaContext* context,
GtkWidget* widget,
int height,
int* minimum_width,
int* 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().
