... and G_TYPE_INSTANCE_GET_PRIVATE()
g_type_class_add_private() and G_TYPE_INSTANCE_GET_PRIVATE() were
deprecated in GLib 2.58. Instead, use
G_DEFINE_[ABSTRACT_]TYPE_WITH_PRIVATE(), and
G_ADD_PRIVATE[_DYNAMIC](), and the implictly-defined
foo_get_instance_private() functions, all of which are available in
the GLib versions we depend on.
This commit only covers types registered using one of the
G_DEFINE_FOO() macros (i.e., most types), but not types with a
custom registration function, of which we still have a few -- GLib
currently only provides a (non-deprecated) public API for adding a
private struct using the G_DEFINE_FOO() macros.
Note that this commit was 99% auto-generated (because I'm not
*that* crazy :), so if there are any style mismatches... we'll have
to live with them for now.
Call gimp_canvas_group_remove_item() and don't just unref them, so
their state gets restored and signals get disconnected. They may not
be owned by the group, or have other external references.
Use a GQueue instead of a GList in GimpCanvasGroup, so adding items
takes constant time instead of O(n). Also, removing items was
traversing the list twice. This should generally speed up tools with
lots of canvas items.
Also, add a private pointer to the instance struct instead of using a
GET_PRIVATE() macro.
and get the shell from gimp_canvas_item_get_shell() if needed. Remove
some cairo_translate() that didn't have any effect and were leftovers
from a very early canvas item code.
This is a gross hack that typedefs around between GdkRegion and
cairo_region_t and has some evil #ifdefs. This is going to die
immeditately once we can depend on cairo 1.10.
and use it to set visibility of guides and sample points, so this
reression is fixed.
- return NULL extents for invisible items and never draw them
- do nothing for invisible items in more places, like the group
While hacking this, it turned out that it was a braino to collect an
item's region before and after a change in
dispatch_properties_changed(), so a new update had to be devised:
- add a "change count" and new API begin_change()/end_change()
- in begin_change(), remember the item's extents before the change
- in end_change(), combine old and current extents and emit "update"
- add some protected function to emit "update", and to figure if
it makes sense at all to emit "update" on an item.
which gets emitted when the item wants to be redrawn:
- Emit "update" it when any item property changes
- Groups connect to their children and forward "update" for them
- The shell connects to its group of canvas items and exposed
the affected area
- Remove gimp_display_shell_expose_item()
- Move all the shell's item group code into gimpdisplayshell-items.c
In order to avoid visually overlapping lines:
- GimpCanvasItem got a "suspend_stroking" API that allows to skip
stroking and instead starts a new sub-path
- GimpCanvasGroup got a "group_stroking" API that sets suspend_stroking
on all its children and does one stroke after calling all items'
draw().
