A crash could happen when a duplicate nick was found due to incorrectly
freeing the content of 'choice->keys' which holds the nicks and not
GimpChoiceDesc. Instead, the nick needs to be simply freed.
New libgimpbase functions:
- gimp_param_spec_choice_get_choice
- gimp_param_spec_choice_get_default
Now the only GParamSpec in libgimpbase whose struct is visible is
GimpParamSpecObject. This can't change since it is derived into param
specs defined in libgimp and therefore needs to be visible.
libgimpbase:
- Mew GimpFileChooserAction enum type: basically a near-mapping of
GtkFileChooserAction (GTK is not accessible from libgimpbase) with
an added GIMP_FILE_CHOOSER_ACTION_ANY.
- New GimpParamSpecFile param spec type: based off
GimpParamSpecObject, it has a default value, but also a none_ok and
action argument. This way, we can also know from the argument type
if this is a file argument meant for selecting a normal file or a
folder, or for saving into a file, or for creating a directory.
libgimp, plug-ins:
- All existing file arguments (until now using a standard
GParamSpecObject param with GFile value type) were moved to the new
GimpParamSpecFile.
- Script-Fu in particular will now generate the appropriate param type
depending on whether it is an SF-FILENAME or SF-DIRNAME.
- File arguments are now stored between runs as a URI rather than as a
path. As far as I can tell, a GFile always has a URI, but not always
a path (in particular remote file won't have a path).
It was possible to set a GimpChoice property to a value out of the
allowed list. This got very likely broken when I re-parented
GimpParamSpecChoice to GParamSpecString which had a value_is_valid()
implementation, which was shadowing our custom value_validate().
This is fixed by now also implementing value_is_valid() for this param
spec type.
Fixes:
> libgimpbase/gimpchoice.c:366: Warning: Gimp: gimp_choice_set_sensitive: invalid return annotation
Introspection step is now fully without any warning! \o/
This is used in the generated GUIs for GimpChoice arguments, but also for
validation of property setting.
New functions:
* gimp_choice_set_sensitive()
* gimp_string_combo_box_set_sensitivity()
This will be used for creating limited lists of strings as argument types for
procedures.
Ideally enums are the best type for this, but it can only be used for generic
libgimp* enum types, not custom enums created only for a given plug-in. For
this, we currently just demote the args to ints which lose any semantic. A
limited list of string will give back some semantic and some better validation,
even though it's a tiny bit more annoying to work with strings than int types
(at least in C).
