- introduce new state "boolean is_first" which tracks if the currently
drawn rectangle is the first with this instance
- cancel the widget if there was no movement when creating the first
rectangle
- undo to the previous rectangle if the user created a zero-extent
rectangle
- also undo to the previous rectangle if a newly drawn rectangle is
canceled with button-3 release
We can't rely on g_object_unref() in halt() for breaking all property
GBindings between the tool options and GimpToolRectangle, because we
might be in the middle of a signal emission which also refs and keeps
the rectangle alive until the last callback returns. So we had
dangling rectangles interacting with tool options.
Remember all bindings in a list, and break them explicitly when we
shut down the rectangle in halt().
Also, forgot to unset the display's highlight in the rectangle
selection tool.
because of bailing out early after emitting "response". Instead, don't
ref the object around this function, and move the "response" emission
to the end of the function.
The tool manager still keeps an active tool which it unrefs on
destruction, triggering a final HALT on the tool, which may want to
lookup tool options to reset something. Happened with the new
widget-ported rectangle select tool.
- enable the setting code in gimp-gegl.c again
- but set the default to one thread in GimpGeglConfig, with a CPP warning
- rename "processors" to "threads" in the GUI
- add a warning box about unexpected results when increasing #threads
We were leaking all tool widgets set with gimp_draw_tool_set_widget(),
and those having signal connections to e.g. the display shell were
doing things when they were supposed to be gone. Fixes make check.
query() is run only the first time for efficiency. Yet this plugin is
dependent on the presence of `rawtherapee` which may be installed or
uninstalled between GIMP startups. Therefore we should move the usual
gimp_install_procedure() to init() so that the check is done at every
startup instead.
Since commit 48046d2, libtiff is a hard dependency. So the have_libtiff
variable is not needed anymore. Just rename it and use it to output a
little bit more informative error message on libtiff check failure.
I wonder if these should not rather be simply removed instead, but well
I'll leave them if the plugin developer needs these regularly for
testing. Use at least C-style comments as per our coding style.
- factor out widget creation to new start() function
- and tool shutdown to new halt() function
- connect to "response" and remove key_press()
- remove oper_update(), it was doing the same as the draw tool impl
- unset "rect_adjusting" before bailing out on button_release()
- update the integer rectangle when the double properties change
- don't try to show handles with a size of < 3
- remove unused members
- shorten some variable names
