If variables are edited directly, in some cases, the GUI and the
symmetries may end up out-of-sync. The variable can only be edited
through property setting.
This value is actually used as a special value when removing a guide to
get rid of a symmetry, in particular it is set in the guides' callback
gimp_mirror_guide_removed_cb() for "removed" signal.
If not setting to 0, when adding back a symmetry, it starts with weird
low or high values near to border (whereas when set to 0, it is reset to
default position afterwards).
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);
As proposed by Mitch. This completes first renaming attempt (commit
08ffc10) with even less ambiguous names.
"horizontal-axis-position" and "vertical-axis-position" are now
respectively "mirror-position-y" and "mirror-position-x".
"Horizontal position" and "Vertical position" could be mistaken as
meaning respectively the x and y coordinates, hence the vertical (resp.
horizontal) guide's positions.
The more accurate "horizontal-axis-position" and "vertical-axis-position"
namings are less misleading.
Mitch gets a better idea to deal with soft limits (i.e. min/max values
different from the property min/max) applied to a spin scale created by
gimp_prop_spin_scale_new().
So let's just remove the current implementation (using locale data on
the GimpConfig object). The symmetry spin scales are back with crazy
huge maximums, which makes quite a horrible GUI, but this is only
temporary until Mitch commits his new implementation.
Currently a GimpSpinScale created with gimp_prop_spin_scale_new() will
use the associated property's lower and upper values.
Unfortunately these generic values may not be always relevant and we
may want to construct a spin scale UI adapted to the current image.
For instance, several symmetry painting have a x/y property which has
to stay within the image's dimension, but changing the property's lower
and upper values would affect the symmetry on the class level (i.e. for
all similar symmetries on all images).
Let's allow setting data on object with key "property-name:min|max" to
provide locale min/max values specifically for this object.
This is used only on the symmetry dock for now, but could be used as
well on GEGL op UIs.
and remove lots of labels from calls to gimp_prop_foo_new(). Also
had to manually remove some unwanted labels that are now added
automatically, fixes bug #761880.
This is not ideal since the scale widget is crazy huge, thus
impractical, but the solution used on properties of other symmetries
(updating min/max of the class property) is wrong since it applies to
the whole class.
For the time being, it avoid setting obviously bad values until we
figure out the ideal automatic UI construction.
Remove GimpSymmetry::get_settings() and instead tag the properties that
should have a GUI with the GIMP_SYMMETRY_PARAM_GUI flag. Also use plain
g_object_class_install_property() because that allows for separate nick
and blurb. Finally, use gimp_prop_gui_new() to generate the GUI,
You can now set any paint tool to mirror painting relatively
horizontal/vertical axis or a central point (any combination of these 3
symmetries).
This has been implemented as a new multi-stroke core, where every stroke
is actually handled as a multi-stroke (default of size 1).
This is also the first usage of custom guides for symmetry guiding.
Current version has to be activated in the playground.
