GtkCustomFilter is a GtkFilter that uses a callback to determine whether to include an item or not.
gboolean
(*GtkCustomFilterFunc) (gpointer item,
gpointer user_data); User function that is called to determine if the item should be matched. If the filter matches the item, this function must return TRUE. If the item should be filtered out, FALSE must be returned.
item | The item to be matched. | [type GObject] |
user_data | user data |
TRUE to keep the item around
GtkCustomFilter * gtk_custom_filter_new (GtkCustomFilterFunc match_func,gpointer user_data,GDestroyNotify user_destroy);
Creates a new filter using the given match_func to filter items.
If match_func is NULL, the filter matches all items.
If the filter func changes its filtering behavior, gtk_filter_changed() needs to be called.
match_func | function to filter items. | [nullable] |
user_data | user data to pass to | [nullable] |
user_destroy | destroy notify for |
a new GtkCustomFilter
void gtk_custom_filter_set_filter_func (GtkCustomFilter *self,GtkCustomFilterFunc match_func,gpointer user_data,GDestroyNotify user_destroy);
Sets (or unsets) the function used for filtering items.
If match_func is NULL, the filter matches all items.
If the filter func changes its filtering behavior, gtk_filter_changed() needs to be called.
If a previous function was set, its user_destroy will be called now.
