splice

Description:

public void splice (uint position, uint n_removals, string[]? additions)

Changes this by removing n_removals strings and adding additions to it.

This function is more efficient than [method@Gtk.StringList.append] and [method@Gtk.StringList.remove], because it only emits the items_changed signal once for the change.

This function copies the strings in additions.

The parameters position and n_removals must be correct (ie: position + n_removals must be less than or equal to the length of the list at the time this function is called).

Parameters:

this	a `GtkStringList`
position	the position at which to make the change
n_removals	the number of strings to remove
additions	The strings to add
