wxPenList: wxList

A pen list is a list containing all pens which have been created. There is only one instance of this class: wxThePenList. Use this object to search for a previously created pen of the desired type and create it if not already found. In some windowing systems, the pen may be a scarce resource, so it is best to reuse old resources if possible. When an application finishes, all pens will be deleted and their resources freed, eliminating the possibility of `memory leaks'.
