Pango.AttrList.splice

### Method

# Pango AttrListsplice

#### Declaration [src]

    void
    pango_attr_list_splice (
      PangoAttrList* list,
      PangoAttrList* other,
      int pos,
      int len
    )

#### Description [src]

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.

This operation is equivalent to stretching every attribute that applies at position `pos` in `list` by an amount `len`, and then calling `pango_attr_list_change()` with a copy of each attribute in `other` in sequence (offset in position by `pos`, and limited in length to `len`).

This operation proves useful for, for instance, inserting a pre-edit string in the middle of an edit buffer.

For backwards compatibility, the function behaves differently when `len` is 0. In this case, the attributes from `other` are not imited to `len`, and are just overlayed on top of `list`.

This mode is useful for merging two lists of attributes together.

#### Parameters

`other`

  Type: `PangoAttrList`

  Another `PangoAttrList`.

  The data is owned by the caller of the method.

`pos`

  Type: `int`

  The position in `list` at which to insert `other`.

`len`

  Type: `int`

  The length of the spliced segment. (Note that this must be specified since the attributes in `other` may only be present at some subsection of this range).
