… gimp_label_spin_set_digits() and deleted gimp_prop_opacity_entry_new()
- The "digits" argument for the number of decimal places in
gimp_prop_scale_entry_new() is now mostly useless since GimpLabelSpin
(hence GimpScaleEntry too) got a nice estimation algorithm of sensible
values.
- Add gimp_label_spin_set_digits() function to manually set the digits
property when we don't like the estimated value.
- Also add a new "factor" argument to gimp_prop_scale_entry_new(). Its
role is to allow a GimpScaleEntry showing a factored range, typically
a [0, 100] range for some types of [0, 1] properties.
- Remove gimp_prop_opacity_entry_new() which was basically a
special-case of gimp_prop_scale_entry_new() and which can now be
easily reproduced by simply set factor=100.0.
- Update all usage of gimp_prop_scale_entry_new() in app/ and plug-ins/
with updated arguments. It is interesting to note that all existing
usage were either integers (digits=1) or when double, the estimated
decimal places are the same as the ones which were manually set (hence
showing the generic estimation is not too bad). So the new function
gimp_label_spin_set_digits() was not even needed once in current code.
Similar code was used in 2 places basically (GimpLabelSpin and
GimpProcedureDialog) so just make it an utils function. It's good anyway
to have a generic function to estimate suitable increments and decimal
places depending on a range.
As a consequence also gimp_label_spin_new() now takes a gint digits
(instead of guint), with -1 meaning we want digits computed from the
range.
Similarly gimp_prop_scale_entry_new() docs adds the -1 meaning too.
There is currently no property widget which just creates a
GimpSpinButton with a label. Just as the GimpScaleEntry was needed, this
one is as well.
I am creating a GimpLabeled abstract class which will represent various
widgets with a label. While this may seem a bit over-engineered for such
a basic feature, this will actually bring some consistency and a common
parent. In particular this can be used to get the GtkLabel with a common
interface to add them all in a common GtkSizeGroup when generating
dialogs automatically, hence make dialogs with properly aligned labels
and edition widgets.
