insert_before

Description:

public void insert_before (out TreeIter iter, TreeIter? sibling)

Inserts a new row before sibling.

If sibling is null, then the row will be appended to the end of the list. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call @set or set_value.

Parameters:

this	A `GtkListStore`
iter	An unset `GtkTreeIter` to set to the new row
sibling	A valid `GtkTreeIter`
