insert

Description:

public void insert (ref TextIter iter, string text, int len)

Inserts len bytes of text at position iter.

If len is -1, text must be nul-terminated and will be inserted in its entirety. Emits the “insert-text” signal; insertion actually occurs in the default handler for the signal. iter is invalidated when insertion occurs (because the buffer contents change), but the default signal handler revalidates it to point to the end of the inserted text.

Parameters:

this	a TextBuffer
iter	a position in the buffer
text	text in UTF-8 format
len	length of text in bytes, or -1
