I am trying to finish the second release of this hpgl interface for ubuntu/linux, The first release is popular but not very feature rich. My problem is I have added two large save and read in settings buttons on the bottom of the gui window. I need to be able to save to a file all the screen options to a chosen filename. I want it to save to ~/bin/xxxx.set (only to that folder) with .set extension and then the reverse reading in xxx.set file and refreshing the gui window. The .set can be visible to the user or not it's for sorting only anyway.
Thanks for your help!
