* Don't generate our own marshallers if they are available in GLib
already
* Don't set the c_marshaller parameter in `g_signal_new()` if it's a
default marshaller provided by GLib. See commit message of commit
39e4aa3c57 on why this is the case.
... 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.
Add an offset_angle parameter to gimp_constrain_line(), which
offsets the radial lines by a given angle.
Add gimpdisplayshell-utils.[ch], with two new functions:
- gimp_display_shell_get_constrained_line_offset_angle():
Returns the offset angle to be passed to
gimp_constrain_line(), in order to constrain line angles in
display space, according to the shell's rotation angle and
flip mode.
- gimp_display_shell_constrain_line(): A convenience function
which calls gimp_constrain_line() with the said offset angle.
Use the new functions in all instances where we constrain line
angles, so that angles are constrained in display space, rather
than image space.
The only exception is GimpEditSelectionTool, which keeps
constraining angles in image space, since it's not entirely obvious
that we want to constrain angles of dragged layers/selections in
display space.
...is a regression in common cases
Commit the free select tool on double click inside the polygon.
Done by implementing GimpCanvasItem::hit() in GimpCanvasPolygon, using
ugly code.
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);
and a default key_press() handler that emits CONFIRM, CANCEL and RESET
responses. Remove code with the same purpose from all subclasses.
Change tools feed key_press() to the widget and connect to its
"response" instead of implementing key_press() themselves. This will
only be better and less code after the tool side of this is done
generically.
Rename gimp_tool_widget_snap_offsets() to set_snap_offsets(),
and add gimp_tool_widget_get_snap_offsets().
Also rename gimp_tool_widget_status() to set_status(), and
add new function and signal set_status_coords().
