1999-06-18 Michael Natterer <mitschel@cs.tu-berlin.de> * app/Makefile.am * app/context_manager.[ch]: new files. Currently only init and destroy the static contexts (user, standard and default). * app/app_procs.c: call the context manager's init and free functions. Still have to figure out the right time to do this. * app/gimpcontext.[ch]: alpha version 0.0.1 :-) Features: - Each context has a name - Attributes: opacity, paint mode, image, display - Signal emission on attribute change - Possibility to set a "parent" context - Each attribute can be defined or undefined. In the latter case the values are taken from the parent context. - Possibility to pass a template and parent context to the constructor Bugs: - Many attributes/functions still missing - It's connected to nothing
