1999-06-21 Michael Natterer <mitschel@cs.tu-berlin.de> * app/context_manager.c: namespace cleanups. * app/commands.[ch] * app/menus.c: moved the "Toggle Selection" menu entry to "View", sprinkled some separators and made the layers/channels/paths popup menus consistent with Tigert's last ops buttons change. * app/fileops.c * app/plug_in.c: check for gdisplay_active() returning NULL in some more places. * app/[all tool related files]: - Turned the ToolAction and ToolState #define's into typedef'ed enums, so the compiler can do some more sanity checking. - Removed one more unused global variable "active_tool_layer". - Removed some #include's from tools.c. - Standardized the individual tools' structure names. - Moved showing/hiding the tool options to separate functions. - Stuff... * app/commands.c * app/disp_callbacks.c * app/gdisplay.c * app/tools.c: fixed the segfaults which happened when the image of one of the tools which have dialogs (levels/posterize/...) was deleted. My approach was to do stricter sanity checking and to set some gdisplay pointers correctly where appropriate, so I can't tell exactly where the bug was. The curves tool now(??) updates on every _second_ display change only, which is really obscure. Finding/changing the display to operate on should definitely be done by connecting to the user context's "display_changed" signal. * app/gimpset.c: emit the "remove" signal _after_ removing the pointer from the set. If this was not a bug but a feature, please let me know, we'll need two signals then.
