We want it to work whatever the level in the item tree. We only care
about whether the items are selected or not.
Also fixing the AppStream release tag for the description of this
feature.
Unlike other locks, visibility lock is less useful for locking a whole
hierarchy of item and their children. On the other hand, being able to
lock a group visibility while editing the children visibility is quite
useful.
I cleaned many remaining places where the concept of linked item still
survived.
On loading an XCF file with linked items, we are now going to create a
named sets for the linked items, allowing people to easily select these
back if the relation was still needed.
We don't remove gimp_item_get_linked() yet and in particular, we don't
save stored items into XCF files. This will come in an upcoming change.
… the selected items only.
This is the exact same algorithm as Shift-click, except that Shift-click
switch exclusivity within the whole level of items. Alt-click does the
same but only within selected items in the list.
Similar to exclusive visibility switch on layers, now for locks too, if
one wants to lock all layers within a same level for instance by
Shift-clicking the lock icon.
Also once again I factorized the exclusive switching code to ensure it
will always works the same for all similar features (visibility and all
locks).
Sometimes one may want to lock visibility of a given layer. This is very
useful in particular when shift-clicking a layer visibility. In this
case, it won't be included in the list of layer to update. This can be
used for instance if you want some layers always visible (or always
hidden) while setting exclusive visibility of some other layers only.
Shift-click should actually toggle only within a given group. The new
capability of toggling only a sub-item, brought by commit 970e9ac is
still feasible in 2 steps: first toggling the parent (item group), then
the desired child.
It brings now a third possibility with exclusive toggle among many
children items, without touching other groups and top-level items.
When toggling visibility of a child in an item group, we should also
toggle the visibility of other items in the same group, as well as
top-level items. Otherwise toggling exclusive visibility of any item in
a group is identical to toggling the parent's exclusive visibility,
which is simply absurd.
We still don't touch visibility of items in other groups.
- don't include <gdk-pixbuf/gdk-pixbuf.h> in headers in app/
- instead, include it in many .c files instead of <glib-object.h>,
finally acknowledging the fact that app/ depends on gdk-pixbuf almost
globally
- fix up includes as if libgimpbase depended in GIO, which it soon will
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.
