Virtual Method
GtkCellAreaget_preferred_height_for_width
Declaration [src]
void
get_preferred_height_for_width (
GtkCellArea* area,
GtkCellAreaContext* context,
GtkWidget* widget,
int width,
int* minimum_height,
int* 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().
