Re: Making plugins

[Larry Dennison <larry avici com>]

Clement,

I too am making a C-based plugin.  I started with the chronogram library as 
it seemed to use the standard Dia property management system.  Some quick 
notes on the integration of the new plugin:

1.  The plugins in are in the objects subdir, forking mostly involves 
copying and renaming.
2.  The Makefile.am in objects will need to know about your new plug-in as 
well.
3.  You'll need to create a stencil (?) sheet in the sheets directory so 
that the Dia gui will know about your plugin.  Makefile.am needs to be 
edited here as well.

I am finding that the standard property management system wasn't expressive 
enough to deal with lists of structures - I have to use the techniques 
found in the UML library.  Note as well that the GtkList structure that the 
UML plugin uses is also deprecated in the latest GTK+.  I'm having to write 
my own using GtkListStore, etc. which is adding a lot of coding work.

Good Luck!
