update_contents

Description:

public void update_contents (AccessibleTextContentChange change, uint start, uint end)

Notifies assistive technologies of a change in contents.

Implementations of the `GtkAccessibleText` interface should call this function every time their contents change as the result of an operation, like an insertion or a removal.

Note: If the change is a deletion, this function must be called *before* removing the contents, if it is an insertion, it must be called *after* inserting the new contents.

Parameters:

this	the accessible object
change	the type of change in the contents
start	the starting offset of the change, in characters
end	the end offset of the change, in characters
