Required creating a registration class for create_option_widget
overload functions because without it the dispatch function
complained of missing symbols at link time.
So that most of the gnome-util and gnome consumers don't need to
be converted to C++.
Hide the corresponding functions in options-utils to stop the
compiler whining.
Note that this commit breaks the build but is necessary at
least temporarily to compartmentalize the changes.
Wraps creating a GncOptionDBPtr, freeing up gnc_option_db_new() to
return a GncOptionDB* for use in C code. Convert gnc_option_db_new()
calls in gtest-gnc-optiondb to call std::make_unique() as well.
Provides find_option(const char*) and foreach_option(func) for easy
iteration. find_option and find_section now return plain const ptrs
instead of std::optionals. Much less cumbersome though the compiler
won't nag if you forget the nullptr check.
To support a variation available in dialog-options. Even though it's not
used in any GnuCash code nor documented anywhere it might be in some
custom reports.
Simplifies the design because derived classes can have whatever save UI class
they need and implement the void(void) set_ui_item_from option and
set_option_from_ui_item with whatever functions are appropriate for
the UI class. No need for callbacks or std::function members.
After getting a better understanding of how it interacts with dialog-options and
finding some additional scheme API needing implementation (exposed only in
hello-world.scm, but possibly used in user-written reports).
Creates a new file-pair, gnc-options-date.[ch]pp to separate the creation of
the static structs with the type info and strings for the various
RelativeDatePeriod values from the already too large gnc-option-impl.
Although the result is a rather C-ish design the alternative with classes
or template specializations would be more complicated and offer no
benefit.
Implements the permissible_values functions of GncOptionMultichoiceValue
for GncDateValue and provides for absolute, relative, and both
UI values for the three widget configs afforded by dialog-options.
From std::string. The consumer is a GtkWidget so we might as well do the conversion
inside the class and this will simplify adding these functions to GncOptionDateValue
in the next commit.
Implemented in gnc-optiondb.i it more clearly indicates the intended
use and restricts the access. Unfortunately further limiting the
friend declaration with #ifdef SWIG prevented the declaration from
working, raising the error "m_option is a private member of GncOption".
Separating the UI from the data model. Note that the GncOptionVariant
classes still have a GncOptionUIType member to ensure that a
GncOptionUIItem of the right type is attached.
