This is replaced with a QVariantMap. It was never really more than this in the
past and with the switch to QgsConfigurationProperties, there is really no
longer any reason to assume that this will change.
Warnings are shown, but features can be committed. Fields which
fail an unenforced constraint are now shaded in yellow to differentiate
from the red failure for enforced constraints.
From the clazy docs:
Finds cases where you're using QMap<K,T> and K is a pointer.
QMap has the particularity of sorting it's keys, but sorting
by memory address makes no sense. Use QHash instead, which
provides faster lookups.
Fixes issues with the current approach:
- poor appearance on certain environments (esp OSX)
- large area on spin boxes' right which "swallows" clicks
and blocks interactivity
Fix#12920
Now the widgets factories can give a score on how good they could handle
a widget.
Additionaly, plugins can be added to choose a widget factory in function
of an external information. One of them uses a table in PostgresQL to
allow specification of the widget type and configuration.
I took the opportunity to remove a few deprecated method in relation to
this.

This commit adds a new mode to the attribute table dialog for searching
and filtering features. When activated (using a button on the toolbar
or by pressng CTRL+F), the dialog will switch to form view and all
widgets are replaced with their search widget wrapper variant.
Alongside each widget is a tool button with options for controlling
the search/filter behaviour for that field, eg "equal to", "not equal
to", "is null", "greater than", etc.., with the options presented
matching themselves to the corresponding field and widget type.
New buttons appear at the bottom of the form for either selecting
matching features (with options for add to selection/remove from
selection/select within current selection) or filtering features
in the table (with options for adding features to a current filter
or further restricting a current filter).

This change allows the attributes of multiple features to be edited
simultaneously. It is enabled when the attribute table dialog is in
"form mode", via a new "multi edit" button on the toolbar.
In this mode, attribute value changes will apply to all selected
features. New widgets appear next to each editor widget allowing for
display of the current multi-edit state and for rolling back changes
on a field-by-field basis.
Changes are made as a single edit command, so pressing undo will
rollback the attribute changes for all selected features at once.
Multiedit mode is only available for auto generated and drag and
drop forms - it is not supported by custom ui forms.

Now all classes and members are either exposed to bindings or marked
as "not available in Python bindings" in the docs.
Drop test thresholds to 0. Now it should be much easier to determine
what missing members have been added which are causing test
failures.
This adds the possibility to manage data on a normalized relational
database in N:M relations. On the relation editor in a form, the tools
to add, delete, link and unlink work (also) on the linking table if a
relation is visualized as N:M relation.
Configuration is done through the fields tab where on the relation a
second relation can be chosen (if there is a suitable relation in terms
of a second relation on the linking table).
Limitations
===========
QGIS is not a database management system.
It is based on assumptions about the underlying database system. In
particular it expects
* A `ON DELETE CASCADE` or similar measure on the second relation
* Does not take care of setting the primary key when adding features.
Either users need to be instructed to set them manually or - if it's a
database derived value - the layers need to be in transaction mode
(currently only activatable through the API)
