GMarkupCollectType

A mixed enumerated type and flags field. You must specify one type (string, strdup, boolean, tristate). Additionally, you may optionally bitwise OR the type with the flag G_MARKUP_COLLECT_OPTIONAL. It is likely that this enum will be extended in the future to support other types. G_MARKUP_COLLECT_INVALID used to terminate the list of attributes to collect G_MARKUP_COLLECT_STRING collect the string pointer directly from the attribute_values[] array. Expects a parameter of type (const char **). If G_MARKUP_COLLECT_OPTIONAL is specified and the attribute isn't present then the pointer will be set to NULL G_MARKUP_COLLECT_STRDUP as with G_MARKUP_COLLECT_STRING, but expects a parameter of type (char **) and g_strdup()s the returned pointer. The pointer must be freed with g_free() G_MARKUP_COLLECT_BOOLEAN expects a parameter of type (gboolean *) and parses the attribute value as a boolean. Sets FALSE if the attribute isn't present. Valid boolean values consist of (case-insensitive) "false", "f", "no", "n", "0" and "true", "t", "yes", "y", "1" G_MARKUP_COLLECT_TRISTATE as with G_MARKUP_COLLECT_BOOLEAN, but in the case of a missing attribute a value is set that compares equal to neither FALSE nor TRUE G_MARKUP_COLLECT_OPTIONAL is implied G_MARKUP_COLLECT_OPTIONAL can be bitwise ORed with the other fields. If present, allows the attribute not to appear. A default value is set depending on what value type is used
