Gtk.Entry.prototype.set_max_length

function set_max_length(max:Number):void {
    // Gjs wrapper for gtk_entry_set_max_length()
}

Sets the maximum allowed length of the contents of the widget. If the current contents are longer than the given length, then they will be truncated to fit.

This is equivalent to:

<informalexample><programlisting> gtk_entry_buffer_set_max_length (gtk_entry_get_buffer (entry), max); </programlisting></informalexample>
