These changes are to align with the changes to column types and also the
basic setup of the new commodity from and currency to combo's. More
changes will follow to make the saving and loading work properly.
Added two combo's to allow user to specify a Commodity from and Currency
to for the whole file. Also reduced the property types to four and
aligned all the commodity and currency variables.
Where possible in the Python SWIG code use the builtin SWIG conversion
code over custom code. This ensures appropriate overflow/type checking.
With this I have enabled GncNumeric from longs and tested for correct
overflow handling.
Note: This could be extended to GUILE but I am not familiar enought to
safely enable this.
At current the Python GncNumeric has issues with type conversion eg.
* GncNumeric(1.3) = 1.00
* GncNumeric("1.3") is OK but any future methods error
This behaviour was relied on for the Account tests to pass as it used
GncNumeric(0.5) == GncNumeric(1.0) but this is not what many users would
expect.
This fix alows GncNumeric to be constructed from a (int, int)
numerator/denominator pair or int/float/str where double_to_gnc_numeric
and string_to_gnc_numeric from C is used.
Only string values should be quoted in queries; in particular NULL
isn't a string value and must not be quoted.
Note that this is a less than perfect solution because it doesn't use
the Database's quoting function and so doesn't escape quotes, linefeeds,
or carriage returns inside the string. That's because the SQL generating
logic is independent of the connection class and can't easily get to it.
The default color of a color option is set during a call to "gnc:make-color-option"
as a list of rgba values. In all color option instances in the scheme code this
default color is incorrectly set to transparent.
For example, white color was being set with:
(list #xff #xff #xff 0)
The last value in the list is the value of the alpha channel, with 0 meaning
transparent. When the color button is displayed in the gui it shows a checkerboard
pattern instead of the intended color.
This commit changes all default colors of color options to have alpha=#xff, i.e.,
fully opaque.
Wherin the problem is that MySQL's TIMESTAMP has a date range of
1970-01-01 00:00:01 to 2038-01-19 03:14:07 and is unable to handle
time_t of 0. MySQL's TIMESTAMP also assumes that input is in the server's
timezone and adjusts it to UTC. GnuCash has already done that conversion.
There did not seem to be an easier way to control the toggle button
width so created a custom one based on the GtkToggleButton. This
allowed the use of the class function get_preferred_width which is set
at two thirds the height.
