Add gimp_item_get_merged_color_tag(), which returns the color tag
of the nearest ancestor (including the current item) that has a
color tag other than NONE. Use this function in GimpItemTreeView,
instead of gimp_item_get_color_tag(), to set the cell color of
items, so that item's with a NONE color tag inherit the color of
their parent. Add a boolean "inherited" parameter to
gimp_get_color_tag_color(), which indicates if the color tag is the
item's actual color tag, or an inherited color tag, and modify the
returned color accordingly, so that inherited colors are less
saturated/lighter than non-inherited ones.
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.
Add property "color-tag" of type enum GimpColorTag to GimpItem so all
layers, channels and paths can be tagged with a color.
For interoperability, use the color list from Krita which is a
superset of Photoshop's colors.
Features a "Color Tag" submenu in the layers, channels and paths
menus, a row of color radio buttons in the properties dialogs,
undo and PDB API.
As a side effect, some common code is now factores out into
items-actions.[ch] and items-commands.[ch] which adds visible, linked
and lock actions for layers and channels.
Apply and heavily modify patch from remyDev which adds "lock position"
to GimpItem, similar to "lock content". Lock position disables all
sorts of translation and transform, from the GUI and the PDB.
Cleaned up some aspects of the lock content code as well because a
second instance of similar code always shows what went wrong the first
time.
but don't fix it for item trees yet (refactoring only). Kill the
"exclusive liked" function which only existed because it was so easy
to have, but was always utterly useless. Prove me wrong and I will
revive it.
Properly distinguish between dropping after a group and into it, by
having three drop areas on a collapsed row. Still handle expanded rows
as before, but indicate dropping into visually just as on a collapsed
row.
In the drop callbacks, don't check if the GimpContainerView's container
contains the dropped item, it might be in a sub-container. Instead,
simply checking if the GimpContainerView knows the item is sufficient
(and also much simpler than a recursive container serach).
Collapsing the tree gets rid of any selection in the collapsed branch,
and doesn't restore it upon exapnding. So connect to the
GtkTreeView::row-expanded signal and select the active item manually.
Had to add evil hack that makes sure we don't try this on child items
that are currently being inserted, because our parent class has no
choice but to expand the tree while the item is not completely
inserted in all subclasses yet.
- gimp_container_tree_view_prepend_toggle_cell_renderer() to
gimp_container_tree_view_add_toggle_cell()
- gimp_container_tree_view_prepend_cell_renderer() to
gimp_container_tree_view_add_renderer_cell()
because "prepend" is an implementation detail, "renderer" is obsolete,
and in the second case it's not "cell renderer" but really a "renderer
cell".
* app/widgets/gimpitemtreeview.[ch]: add class members for the lock
content button's icon, tooltip and help_id and use them when
creating the button. Create the button in constructor() instead of
init() so we have access to our real class structure without the
need for a custom get_type() function.
* app/widgets/gimpdrawabletreeview.c: configure the button as "Lock pixels".
* app/widgets/gimpvectorstreeview.c: configure it as "Lock path strokes".
- new API to add widgets to a box of options, for stuff like the paint
mode menu and opacity scale. Set it sensitive automatically and
update its spacings in GtkWidget::style_set().
- new API to get a hbox for "lock" toggles, for stuff like lock
pixels and lock alpha.
* app/core/gimpimage.[ch]: rename all gimp_image_reposition_foo() to
gimp_image_reorder_foo() and added "new_parent" parameters. Factor
out calculating of the item's new container and index to a utility
function.
* app/core/core-enums.[ch]: rename the REPOSITION undos to REORDER.
* app/core/gimpimage-undo-push.[ch]
* app/core/gimpchannelpropundo.[ch]
* app/core/gimplayerpropundo.[ch]
* app/vectors/gimpvectorspropundo.[ch]: change accordingly. Remember
the old parent item in all item reorder undos.
* app/widgets/gimpitemtreeview.h: change GimpReorderItemFunc prototype
accordingly.
* app/widgets/gimpchanneltreeview.c
* app/widgets/gimplayertreeview.c
* app/widgets/gimpvectorstreeview.c (class_init): follow image API
name changes.
* app/widgets/gimpitemtreeview.c (gimp_item_tree_view_drop_viewable):
implement reordering of items between groups.
* app/widgets/gimpcontainertreeview.c
(gimp_container_tree_view_reorder_item): fix to reorder the item
within its level of the tree (unrelated to above changes, but needed
to make them work).
* app/widgets/gimpcontainertreeview-dnd.c
(gimp_container_tree_view_real_drop_possible): support DND within a
tree and make sure a group item is not dropped into itself.
* app/widgets/gimpitemtreeview.c (gimp_item_tree_view_drop_viewable):
implement intra-container reordering within all branches; print a
message for inter-container reordering because that's not yet
implemented in the core.
