A "filled marker" is similar to the simple marker symbol layer, except
that it uses a fill sub symbol to render the marker. This allows use
of all the existing QGIS fill (and outline) styles for rendering
markers, eg gradient or shapeburst fills.
A new abstract class QgsSimpleMarkerSymbolLayerBase has been created
from which both QgsSimpleMarkerSymbolLayerV2 and
QgsFilledMarkerSymbolLayer derive. All common code has been moved to
this base class, allowing for easy addition of new shapes or features
to both simple markers and filled markers without duplication.
Also, adds a lot of missing docs to marker symbol layers.
- Closes https://hub.qgis.org/issues/14378
- Adds new virtual methods in QgsDataProvider(): enterUpdateMode() and leaveUpdateMode()
and implement them in the OGR provider. Limited to shapefiles and tabfiles
- Implements QgsOGRProvider:reloadData()
- Robustify OGR provider methods so they don't crash if dataset re-opening fails.
Usually QObjects must subclass and override methods like focusOutEvent
to handle focus events. Using this class as an event filter avoids
the need to subclass objects and the focus events can be directly
caught using the emitted signals.
Useful for GPKG and other database based drivers
- For OGR drivers that have GetFIDColumn() != '', expose it as a QGIS
field.
- When creating features, use the value potentially provided in this
first field, as the feature id to force to OGR. Disallow changing it
in changeAttributeValues()
- show correct domain type as field type name
- correctly determine length and precision of domain types
- expose bpchar field type as 'character' to users, as postgres only
uses 'bpchar' internally and refers to bpchar as character in the
front end
A new "legend" tab has been added to diagram properties, allowing
both the existing attribute legend and a new size legend to be
enabled/disabled. The size legend has a configurable marker
symbol.
Also includes unit tests for both diagram attribute and size
legends.

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.
