PgAttributeList

The #PangoAttrList structure represents a list of attributes that apply to a section of text. The attributes are, in general, allowed to overlap in an arbitrary fashion, however, if the attributes are manipulated only through pango_attr_list_change(), the overlap between properties will meet stricter criteria.

Since the #PangoAttrList structure is stored as a linear list, it is not suitable for storing attributes for large amounts of text. In general, you should not use a single #PangoAttrList for more than one paragraph of text.

Constructors

this this(PangoAttrList* pangoAttrList, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(): Create a new empty attribute list with a reference count of one.

Functions

change void change(PgAttribute attr): Insert the given attribute into the #PangoAttrList. It will replace any attributes of the same type on that segment and be merged with any adjoining attributes that are identical.
copy PgAttributeList copy(): Copy @list and return an identical new list.
doref PgAttributeList doref(): Increase the reference count of the given attribute list by one.
filter PgAttributeList filter(PangoAttrFilterFunc func, void* data): Given a #PangoAttrList and callback function, removes any elements of @list for which @func returns %TRUE and inserts them into a new list.
getIterator PgAttributeIterator getIterator(): Create a iterator initialized to the beginning of the list. @list must not be modified until this iterator is freed.
getPgAttributeListStruct PangoAttrList* getPgAttributeListStruct(): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
insert void insert(PgAttribute attr): Insert the given attribute into the #PangoAttrList. It will be inserted after all other attributes with a matching @start_index.
insertBefore void insertBefore(PgAttribute attr): Insert the given attribute into the #PangoAttrList. It will be inserted before all other attributes with a matching @start_index.
splice void splice(PgAttributeList other, int pos, int len): This function opens up a hole in @list, fills it in with attributes from the left, and then merges @other on top of the hole.
unref void unref(): Decrease the reference count of the given attribute list by one. If the result is zero, free the attribute list and the attributes it contains.
