1999-10-17 Michael Natterer <mitch@gimp.org>
* app/gimpcontext.[ch]: added the possibility to store the current
tool, FG/BG color, brush, pattern and gradient, but don't use
these attributes yet.
Before replacing the get/set color/brush/... functions with
context functions, I'll have to change the "parent context"
implementation to something where the children catch the parent's
color/brush/..._changed signals.
Finally, updating the indicator_area, device_status, tool_options
etc. will be done by connecting to their own context's "*_changed"
signals, which will be much cleaner than calling the update
functions from various places.
(I think this is a "consistency fix", please let me know if you
consider it a new feature).

added the possibility to store the current tool, FG/BG color, brush,
1999-10-17 Michael Natterer <mitch@gimp.org>
* app/gimpcontext.[ch]: added the possibility to store the current
tool, FG/BG color, brush, pattern and gradient, but don't use
these attributes yet.
Before replacing the get/set color/brush/... functions with
context functions, I'll have to change the "parent context"
implementation to something where the children catch the parent's
color/brush/..._changed signals.
Finally, updating the indicator_area, device_status, tool_options
etc. will be done by connecting to their own context's "*_changed"
signals, which will be much cleaner than calling the update
functions from various places.
(I think this is a "consistency fix", please let me know if you
consider it a new feature).
