... after erasing all points
When erasing the last remaining point in the iscissors tool, halt
the tool, rather than leaving the tool active with an empty curve,
which it is not prepared to handle, and which results in a segfault
once trying to add a new point.
Additionally, when erasing the last remaining segment (i.e., the
two last remaining points), don't erase the entire segment (i.e.,
both points), but rather convert the segment to its initial point,
so that, in effect, we only erase the last point of the segment.
More than 2000 lines of code less in app/, instead of
if (instance->member)
{
g_object_unref/g_free/g_whatever (instance->member);
instance->member = NULL;
}
we now simply use
g_clear_object/pointer (&instance->member);
Call HALT generically in gimp_tool_control() after calling COMMIT, and
remove all hacks in tools that call both COMMIT and HALT or call
halt() from commit().
Some tools interact with their subclasses (e.g. filter tool and
operation tool), and it's essential that COMMIT runs through the
entire class hierarchy before HALT.
Probably breaks something, please test.
to ::can_undo() and ::can_redo(). They still return description
strings and the new naming is slightly off :) but get_undo_desc() will
be needed for something else soon, and half of the time the functions
are indeed used to check whether there are undo/redo staps at all.
Try to sort all GIMP_ICON_* defines into FDO categories like in
https://specifications.freedesktop.org/icon-naming-spec/latest/ar01s04.html
Add defines for all icons we override, rename some icons to their FDO
standard names, and mark the ones we duplicate with a comment so we
don't forget to rename those to standard names in 3.0.
gimp_suggest_modifiers(): change "shift_format" and "control_format"
parameters to "extend_selection_format" and "toggle_behavior_format",
which fixes the longstanding problem that the function did the right
thing only by accident.
tools: use gimp_get_extend_selection_mask() instead of GDK_SHIFT_MASK
which is not 100% semantically correct in all cases, but at least a
step in the right direction to make the tool modifiers easier to
improve.
Add undo to the Isissors tool, along with some refactoring:
- Always modify the actual curve, instead of a set of obscure states
kept around in the tool instance
- On cancel, simply go back to the curve on the undo stack
- Draw handles on top of curve segments
- Draw the currently edited segments and handles in the highlight color
The interaction is fully restored, it's also ported to the new halt()
and commit() API of tools and semi-properly GEGLized: the gradient map
is now constructed on the fly using a GimpTileHandlerValidate
subclass.
The only problem is that it doesn't find any edges in the image and is
totally useless. Pushing anyway to put an end to the bitrot, any help
with debugging is greatly appreciated...
Reset the tool on image changes again, but not if only the active
drawable changes, so keep bug #678890 closed:
Introduce new dirty flag GIMP_DIRTY_ACTIVE_DRAWABLE and set it on all
tools' dirty_mask except for rect select. Check the new flag when
reseting the active tool because of a drawable change.
