update


Description:

[ Version ( since = "1.44" ) ]
public void update (int pos, int remove, int add)

Update indices of attributes in this for a change in the text they refer to.

The change that this function applies is removing remove bytes at position pos and inserting add bytes instead.

Attributes that fall entirely in the (pos, pos + remove) range are removed.

Attributes that start or end inside the (pos, pos + remove) range are shortened to reflect the removal.

Attributes start and end positions are updated if they are behind pos + remove.

Parameters:

this

a `PangoAttrList`

pos

the position of the change

remove

the number of removed bytes

add

the number of added bytes
